Any given Y(n) among the set of Y1, Y2, ..., Y100, the probability of Y(n) being less than 1.9 is 0.475.

a) To compute P[2Y < 1.9], where Y is a Uniform(0, 2) random variable, we need to find the probability that twice the value of Y is less than 1.9. The Uniform(0, 2) distribution has a constant probability density function of 1/2 within the interval (0, 2). Since Y is uniformly distributed, the probability that Y takes any specific value within (0, 2) is equal.

To calculate the probability, we need to find the proportion of the interval (0, 2) where 2Y is less than 1.9. Dividing 1.9 by 2 gives us 0.95, and we need to find the proportion of the interval (0, 2) that lies to the left of 0.95. This proportion can be calculated as (0.95 - 0) / 2 = 0.475. Therefore, P[2Y < 1.9] is equal to 0.475.

b) P[Y(n) < 1.9] refers to the probability that a specific random variable, denoted as Y(n), is less than 1.9. Since Y(n) is part of the set of independent Uniform(0, 2) random variables, the probability calculation is the same as in part a). Each Y(n) follows the same distribution, and we can find the proportion of the interval (0, 2) where Y(n) is less than 1.9.

Using the same calculation as before, we determine that P[Y(n) < 1.9] is equal to 0.475. Therefore, for any given Y(n) among the set of Y1, Y2, ..., Y100, the probability of Y(n) being less than 1.9 is 0.475.

The random variable Y = F(X) is uniformly distributed over (0, 1).

Let's start by finding the CDF of Y uniformly distributed. The CDF of Y is defined as the probability that Y takes on a value less than or equal to a given number y. Mathematically, it can be written as:

CDF_Y(y) = P(Y ≤ y)

Now, let's consider a specific value y in the interval (0, 1). We want to find the probability that Y is less than or equal to y, i.e., P(Y ≤ y).

P(Y ≤ y) = P(F(X) ≤ y)

Since F is the CDF of the random variable X, we can rewrite this as:

P(F(X) ≤ y) = P(X ≤ F^(-1)(y))

Here, F^(-1) represents the inverse function of F. Note that F^(-1)(y) is the value of X for which the CDF equals y.

Now, let's analyze this expression further. Since X is a continuous random variable, its CDF F is a continuous function. This implies that P(X = F^(-1)(y)) = 0 for any specific value of y.

Therefore, we can rewrite the probability as:

P(X ≤ F^(-1)(y)) = P(X < F^(-1)(y))

The inequality X < F^(-1)(y) can be written in terms of F as:

F(X) < y

Since Y = F(X), we can rewrite the inequality as:

Y < y

Now, let's find the probability P(Y < y):

P(Y < y) = P(F(X) < y) = P(X < F^(-1)(y))

Since X is a continuous random variable, P(X < F^(-1)(y)) is the same as the CDF of X evaluated at F^(-1)(y), which is F(F^(-1)(y)).

Therefore, we have:

P(Y < y) = F(F^(-1)(y))

Now, consider the case when y = 1. The probability P(Y < 1) is:

P(Y < 1) = F(F^(-1)(1))

But F^(-1)(1) is the maximum value that X can take, which is denoted as x_max.

Therefore, we have:

P(Y < 1) = F(x_max)

Since x_max is the largest possible value for X, its CDF F(x_max) is equal to 1.

So, we have:

P(Y < 1) = 1

Now, consider the case when y = 0. The probability P(Y < 0) is:

P(Y < 0) = F(F^(-1)(0))

But F^(-1)(0) is the minimum value that X can take, which is denoted as x_min.

Therefore, we have:

P(Y < 0) = F(x_min)

Since x_min is the smallest possible value for X, its CDF F(x_min) is equal to 0.

So, we have:

P(Y < 0) = 0

In summary, we have shown that for any y in the interval (0, 1):

P(Y < y) = F(F^(-1)(y))

Since the CDF of Y satisfies the properties of a uniform distribution over (0, 1), we can conclude that the random variable Y = F(X) is uniformly distributed over (0, 1).

Main Answer: The value of ∂z/∂s = (e^(s/t))/t - 2t/(s^3)  and ∂z/∂t = -(e^(s/t)) × s/(t^3) + 2/(s^2)

Supporting Question and Answer:

How do you differentiate the function z = ex + 2y with respect to s and t using the chain rule when x = s/t and y = t/s?

To differentiate z with respect to s and t using the chain rule, we substitute the expressions for x and y in terms of s and t, and then differentiate each term separately.

Body of the Solution: To find ∂z/∂s and ∂z/∂t using the chain rule, we'll express z in terms of s and t and then differentiate with respect to each variable separately.

Given: z = e^x + 2y

x = s/t

y = t/s

First, let's express z in terms of s and t by substituting the expressions for x and y:

z = e^(s/t) + 2(t/s)

Now, we'll differentiate z with respect to s using the chain rule:

∂z/∂s = (e^(s/t)) × (1/t) + 2 × (1/s) × (-t/s^2)

Simplifying, we get:

∂z/∂s = (e^(s/t))/t - 2t/(s^3)

Next, we'll differentiate z with respect to t using the chain rule:

∂z/∂t = (e^(s/t)) × (-s/t^2) + 2 × (1/s) × (1/s)

Simplifying, we get:

∂z/∂t = -(e^(s/t)) ×s/(t^3) + 2/(s^2)

Final Answer: Therefore, the partial derivatives are:

∂z/∂s = (e^(s/t))/t - 2t/(s^3)

∂z/∂t = -(e^(s/t)) × s/(t^3) + 2/(s^2)

To find the expected return on a $1 ticket, we need to calculate the total winnings and divide it by the number of tickets sold.

Let's calculate the expected return step by step: The grand prize is $3,000,000, and there is only one winner, so the contribution to the total winnings from the grand prize is $3,000,000. There are 3 runner-up prizes of $141,000 each, so the total contribution from the runner-up prizes is 3 * $141,000 = $423,000. Similarly, there are 8 third-place prizes of $68,000 each, so the total contribution from the third-place prizes is 8 * $68,000 = $544,000. Finally, there are 19 consolation prizes of $200 each, so the total contribution from the consolation prizes is 19 * $200 = $3,800.

Adding up all the contributions, we get a total winnings of $3,000,000 + $423,000 + $544,000 + $3,800 = $3,970,800. Since there are 35 million tickets sold for $1 each, the total amount collected is 35 million * $1 = $35 million.

To find the expected return on a $1 ticket, we divide the total winnings by the number of tickets sold: Expected Return = $3,970,800 / $35,000,000 ≈ $0.113 (rounded to the nearest cent). Therefore, the expected return on a $1 ticket is approximately $0.113.

2) The probability that the first coin you pick is a nickel and the second coin is a dime is 0.25.

1) In the cooler, there are a total of 14 bottles of sports drink: 8 lemon-lime flavored and 6 orange flavored. When you randomly grab a bottle for your friend and another one for yourself, you both end up with lemon-lime flavored drinks.

The probability of this happening can be calculated as the probability of picking a lemon-lime bottle for your friend and then, given that, picking another lemon-lime bottle for yourself:

P(both lemon-lime) = P(lemon-lime for friend) * P(lemon-lime for yourself)

= (8/14) * (7/13)

= 56/182

≈ 0.3077

2) Next, you randomly pick a coin from your pocket and place it on the counter. Then, you randomly pick another coin. The first coin is a nickel and the second coin is a dime. Since the coins are selected randomly, the probability of these specific outcomes can be calculated as the product of the individual probabilities:

P(nickel and dime) = P(nickel) * P(dime)

= (1/2) * (1/2)

= 1/4

= 0.25

Therefore, the probability that the first coin you picked is a nickel and the second coin is a dime is 0.25.

When assessing the performance of a model in terms of small residuals and good predictive power, the preferred concept commonly used is the mean squared error (MSE).

MSE is a measure of the average squared difference between the predicted values of a model and the actual values. It provides an indication of how well the model fits the data and how close the predicted values are to the true values. The lower the MSE, the better the model's predictive power and the smaller the residuals, which are the differences between the predicted and actual values.

While other concepts such as the correlation coefficient, goodness of fit, and unbiasedness are also important in evaluating a model, MSE is specifically focused on the accuracy of predictions and the residuals. It is widely used because it provides a quantitative measure that can be compared across different models and helps in selecting the best model for the given data. The Wiener integral, on the other hand, is a concept related to stochastic processes and is not directly applicable in assessing model performance in terms of residuals and predictive power.

When assessing the model's performance in terms of small residuals and good predictive power, the preferred concept to consider is the correlation coefficient.

The correlation coefficient measures the strength and direction of the linear relationship between the predicted values and the actual values. It provides insights into how well the model's predictions align with the observed data. A high correlation coefficient indicates a strong linear relationship and suggests that the model's predictions are closely related to the actual values.

In the context of model evaluation, a higher correlation coefficient is desirable as it indicates a better fit of the model to the data. It suggests that the model's predictions capture a significant portion of the variation in the observed values. On the other hand, a low correlation coefficient suggests a weak relationship and implies that the model's predictions are not accurate or consistent with the actual values.

While mean squared error (MSE), goodness of fit, and unbiasedness are also important concepts in model evaluation, the correlation coefficient specifically focuses on the strength of the linear relationship and is commonly used to assess the model's predictive power and the extent to which it captures the underlying patterns in the data.

Yes, that is correct.

The model for the speed of an object of mass m dropped from rest, taking air resistance into account, is given by:

v = m g c (1 - e^(-c t / m))

where:

- v is the speed of the object in meters per second (m/s)

- g is the acceleration due to gravity in meters per second squared (m/s^2)

- c is a positive constant related to the air resistance and the properties of the object

- t is the time elapsed in seconds.

This model takes into account the fact that as the object falls, it experiences air resistance which opposes its motion and reduces its acceleration. The term (1 - e^(-c t / m)) represents the fraction of the object's weight that is accelerating it downward at any given time, and is a function of the time elapsed since the object was dropped.

As time goes on, this fraction approaches 1 and the object's speed approaches a terminal velocity, at which point the downward force due to gravity is balanced by the upward force due to air resistance, resulting in a constant speed.

When there is an increase in the money supply, the new long-run equilibrium is determined by point B on the aggregate demand and supply model.

In the aggregate demand and supply model, the equilibrium represents the point where aggregate demand (AD) and aggregate supply (AS) intersect, indicating a stable state of the economy. The original equilibrium is represented by point A.

When the money supply increases, it affects the economy in several ways. An increase in the money supply leads to a decrease in interest rates. Lower interest rates encourage borrowing and investment, which in turn stimulates aggregate demand. As a result, the aggregate demand curve shifts to the right.

The shift in aggregate demand causes an increase in both output and prices in the short run. However, in the long run, prices adjust to reflect the increased money supply. As prices rise, the short-run aggregate supply curve shifts to the left until it intersects with the new aggregate demand curve.

The long-run equilibrium is determined by the point where the new aggregate demand curve intersects with the adjusted aggregate supply curve, represented by point B. At this new equilibrium, both output and prices are higher than the original equilibrium (point A).

The approximate dimension of the Sierpinski carpet, a fractal shape related to the Sierpinski gasket and the Menger sponge, can be found by calculating the logarithm of the number.

The Sierpinski carpet is created by starting with a square and iteratively removing the center and dividing the remaining squares into smaller squares. Each step increases the number of self-similar copies of the shape.

To find the approximate dimension, we calculate the logarithm of the number of self-similar copies needed to cover the shape and divide it by the logarithm of the scaling factor, which is the ratio of the length of each square in the iteration to the length of the previous square.

The resulting value represents the fractal dimension, which quantifies the space-filling properties of the fractal. By rounding this value to the nearest tenth, we can estimate the dimension of the Sierpinski carpet and gain insight into its intricate and complex structure.

The probability that a randomly selected woman will be 60 inches or less is approximately 0.0139, or 1.39%.

To find the probability that a randomly selected woman will be 60 inches or less, we need to calculate the area under the normal distribution curve up to 60 inches.

First, we need to standardize the height using the z-score formula:

z = (x - μ) / σ

where:

x = 60 inches (the value we want to find the probability for)

μ = mean height = 65.5 inches

σ = standard deviation = 2.5 inches

Substituting the values into the formula, we get:

z = (60 - 65.5) / 2.5

z = -2.2

Next, we need to find the cumulative probability up to the z-score of -2.2. We can look up this value in the standard normal distribution table or use statistical software.

Using a standard normal distribution table, we find that the cumulative probability corresponding to a z-score of -2.2 is approximately 0.0139.

Therefore, the probability that a randomly selected woman will be 60 inches or less is approximately 0.0139, or 1.39%.

Mathematician: Évariste Galois

(1) Life History:

Évariste Galois was born in Bourg-la-Reine, France on October 25, 1811. Unfortunately, he passed away at the tender age of 20 on May 31, 1832. Amidst the political unrest in France, he engaged in political activism. Despite his premature death, Galois made a lasting impact on the field of mathematics. His non-conformist attitude and intelligence frequently led to conflicts with those in positions of power, earning him a reputation as a rebel. A fascinating piece of information is that Galois dedicated his night prior to his ultimate combat to jotting down his mathematical concepts, eventually emerging as notable enhancements to Algebra.

(2) Mathematical Discoveries:

Galois made remarkable contributions to the field of Algebra. He developed the theory of Galois groups, which revolutionized the study of polynomial equations and their solvability. Galois showed that the solvability of an algebraic equation by radicals is determined by the properties of its Galois group. This insight led to Galois theory, a cornerstone of modern Algebra. Additionally, he developed the concept of field theory, introducing the notion of field extensions, which provided a powerful framework for studying algebraic structures.

In spherical coordinates, ρ represents the radial distance from the origin, φ represents the inclination or polar angle, and θ represents the azimuthal angle.

For the bottom half of a sphere, the range of ϕ is from 0 to π/2, and the range of θ is from 0 to 2π.

x=0, y=1: 2/9

x=1, y=0: 2/9

x=1, y=1: 4/9

Based on the given information, we can determine the marginal probability distributions for x and y:

For x:

f(x=1) = 2/3

For y, since it is independent of x, the probabilities remain the same:

f(y=0) = 1/3

f(y=1) = 2/3

To find the joint probability distribution, we multiply the probabilities for x and y since they are independent:

f(x=0, y=0) = f(x=0) * f(y=0) = (1/3) * (1/3) = 1/9

f(x=0, y=1) = f(x=0) * f(y=1) = (1/3) * (2/3) = 2/9

f(x=1, y=0) = f(x=1) * f(y=0) = (2/3) * (1/3) = 2/9

f(x=1, y=1) = f(x=1) * f(y=1) = (2/3) * (2/3) = 4/9

Therefore, the joint probability distribution for x and y is as follows:

The given hash function, h(key) = key modulo 11, calculates the remainder when the key is divided by 11. In this case, to determine the index to which the key 47 will hash, we need to compute 47 modulo 11.

Dividing 47 by 11, we get 4 as the quotient with a remainder of 3. Therefore, 47 modulo 11 equals 3. This means that the key 47 will hash to index 3 in the hash table.

The hash function modulo operation distributes the keys uniformly across the available indices, ensuring a balanced distribution of values in the hash table. The use of modulo 11 in this hash function limits the indices to a range of 0 to 10.

The resulting index is determined solely by the remainder, allowing efficient retrieval and storage of values based on their keys.

Answer:

1 meter

Step-by-step explanation:

The volume of a rectangular prism is length*width*height.

Therefore, if we just set the length as a variable "l" and plug in the numbers into the equation, we get 35l=35.

Dividing both sides by 35, we get 1 meter.

Among the given options, the following statements could be true about the eigenvalues of a 4x4 matrix A:

Let's analyze each option one by one:

There could be one eigenvalue of algebraic multiplicity 2 and one of algebraic multiplicity 3:

For this to be true, the matrix A must have at least two distinct eigenvalues. The eigenvalue with algebraic multiplicity 2 means that it is a repeated eigenvalue. The eigenvalue with algebraic multiplicity 3 means that it is repeated three times. Therefore, this option is possible.

There could be 4 eigenvalues of algebraic multiplicity 2:

For a 4x4 matrix, it can have at most 4 distinct eigenvalues. However, each eigenvalue with algebraic multiplicity 2 would imply a total of 8 eigenvalues, which is not possible. Therefore, this option is not possible.

There could be no real eigenvalues:

This option is possible since a matrix can have complex eigenvalues. The eigenvalues may be complex conjugates, resulting in no real eigenvalues.

There could be 2 eigenvalues, each of algebraic multiplicity 1, and no other eigenvalues:

For this to be true, the matrix A must have exactly two distinct eigenvalues, each with algebraic multiplicity 1. This means that each eigenvalue appears only once. Since the matrix is 4x4, the remaining two eigenvalues would be zero. Therefore, this option is possible.

Answer:

Hispanics Account for More than Half of Nation's Growth in ...

The 2010 Census counted 50.5 million Hispanics in the United States, making up 16.3% of the total population. The nation's Latino population, which was 35.3 million in 2000, grew 43% over the decade.

Step-by-step explanation:

This answer provides step by step guidance to understanding a data set comprising of the Hispanic population in the US. It guides through the interpretation of the provided spreadsheet, the creation and interpretation of histograms and box plots, and the identification and analysis of outliers.

Since I'm not able to interact directly with your provided spreadsheet and tools, I'll guide you along the process. On Brainly, tutors can't provide images or interactive tools.

The 'Number' column represents the actual count of Hispanic/Latino population in a given location. The '% of Total Population' column represents the proportion of the Hispanic/Latino population against the total population in the same location. The 'Total' column, in this context, likely represents the total population of a given location.

For histogram and box plot creations, first copy the column of data you need, then paste it into the respective tool. Make sure to set meaningful limits and label your graphics appropriately. These visuals will help in understanding the distribution of the data.

Analyze your plots. Look for whether the data is symmetric (normal), skewed left (negative) or skewed right (positive). 'Spread' refers to the variability in your data, a key indicator might be the difference between maximum and minimum values discussed in Part B.

Central tendencies can be understood as the 'middle' or 'average' of the data. In a histogram, look for peaks, which represent the mode of the distribution. For a box plot, calculate the median (Q2), essentially the mid-point of the plotted data.

To find min/max values excluding outliers, look for the smallest/largest value that falls within the range defined by Q1 - 1.5*(IQR) and Q3 + 1.5*(IQR). Outliers are the data points outside this range. Check back to see which states these outliers correspond to.

Compare the given 16.3% to your box plot. Depending on where it fits within the plot's quartiles, it may or may not be surprising due to differing state-level proportions vs the overall distribution. Explanation might involve immigration, cultural hubs, or state-specific policies among others.

To estimate the total distance the runner travels from t=0 to t=6 seconds using trapezoids, we need to use the formula for the area of a trapezoid which is (base1 + base2) * height / 2.

We can estimate the distance traveled by dividing the time interval into smaller intervals and calculating the average velocity for each interval.
Let's divide the time interval into six smaller intervals of 1 second each. The velocity at each second is given as follows:
t=0: 0 m/s
t=1: 3 m/s
t=2: 6 m/s
t=3: 8 m/s
t=4: 10 m/s
t=5: 9 m/s
t=6: 0 m/s
Now, let's calculate the distance traveled during each interval using trapezoids:
Interval 1: (0 + 3) * 1 / 2 = 1.5 m
Interval 2: (3 + 6) * 1 / 2 = 4.5 m
Interval 3: (6 + 8) * 1 / 2 = 7 m
Interval 4: (8 + 10) * 1 / 2 = 9 m
Interval 5: (10 + 9) * 1 / 2 = 9.5 m
Interval 6: (9 + 0) * 1 / 2 = 4.5 m
The total distance traveled is the sum of the distances traveled in each interval:
Total distance = 1.5 + 4.5 + 7 + 9 + 9.5 + 4.5 = 36 m
Therefore, the answer is not provided in the given options. The total distance traveled by the runner from t=0 to t=6 seconds is approximately 36 meters.

A) The proportion of the sample of 300 that would be expected to be women can be calculated by multiplying the proportion of adult women in the geographical region (49%) by the sample size:

Proportion of sample = 0.49 * 300 = 147

Therefore, we would expect approximately 147 out of the 300 sampled individuals to be women.

B) The standard deviation of the sampling distribution, denoted as SD, can be calculated using the formula:

SD = sqrt(p * (1 - p) / n)

Where:

p is the proportion of adult women in the geographical region (0.49)

n is the sample size (300)

SD = sqrt(0.49 * (1 - 0.49) / 300) ≈ sqrt(0.2451 / 300) ≈ sqrt(0.000817)

SD ≈ 0.02858

Therefore, the standard deviation of the sampling distribution is approximately 0.02858.

The diameter of a single marble is approximately 35.4 cm^3 / 23.6 cm^2 = 1.5 cm.  This behavior occurs due to the amphiphilic nature of oleic acid, where the hydrophobic and hydrophilic parts of the molecule segregate to minimize energy. The resulting standing columnar structure is a result of this self-assembly process.

The equation that relates the cross-sectional area (A), the volume (V), and the thickness (t) of a cylinder is A = V/t. In this context, it represents the relationship between the area of a cross-section, the volume enclosed by that cross-section, and the thickness of the cylinder. In the case of oleic acid molecules, an assumption is made that they stand up like columns due to their chemical structure, with hydrophobic tails pointing downwards and hydrophilic heads pointing upwards. Given an area of a monolayer of marbles and the total volume of the marbles, we can calculate the approximate diameter (thickness) of a single marble.

Oleic acid molecules have a hydrophobic tail and a hydrophilic head. When a monolayer of oleic acid molecules forms, the hydrophobic tails orient themselves away from the water, while the hydrophilic heads face the water. This behavior occurs due to the amphiphilic nature of oleic acid, where the hydrophobic and hydrophilic parts of the molecule segregate to minimize energy. The resulting standing columnar structure is a result of this self-assembly process.

By mathematical induction, the characteristic polynomial of matrix A is (-1)^k * (ao + a1λ + ... + ak-1λ^(k-1) + λ^k), as desired.

To prove that the characteristic polynomial of matrix A is (-1)^(k) * det(A - λI), where λ is the eigenvalue and I is the identity matrix, we will use mathematical induction on k.

Base Case (k = 1):

For k = 1, matrix A is simply a 1x1 matrix with entry 100. The characteristic polynomial is det(A - λI) = det(100 - λ), which is equal to (-1)^1 * (λ - 100) = (-1)^1 * (a0 - 100).

Inductive Step:

Assume that the statement holds for a k x k matrix. We will prove it for a (k+1) x (k+1) matrix.

Let A' denote the (k+1) x (k+1) matrix with entries given as:

100 ... 0

1 0 ... 0

0 1 ... 0

...

0 0 ... 1

-a0 -a1 ... -ak-2 -ak-1

We will compute the determinant of A' - λI by expanding along the first row. We obtain:

det(A' - λI) = (100 - λ) * cofactor(1,1) - (-1)^(k+1) * a0 * cofactor(1,2) + (-1)^(k+1) * a1 * cofactor(1,3) - ... - (-1)^(k+1) * ak-1 * cofactor(1,k+1)

Expanding each cofactor, we can express them as determinants of (k x k) matrices:

det(A' - λI) = (100 - λ) * det(B) - (-1)^(k+1) * a0 * det(C0) + (-1)^(k+1) * a1 * det(C1) - ... - (-1)^(k+1) * ak-1 * det(Ck-1)

Here, B is a (k x k) matrix obtained by deleting the first row and column of A', and C0, C1, ..., Ck-1 are (k x k) matrices obtained by deleting the first row and columns 2, 3, ..., k+1 of A'.

By the induction hypothesis, the characteristic polynomial of B is (-1)^k * det(B - λI) = (-1)^k * (-1)^(k-1) * (a0 + a1λ + ... + ak-1λ^(k-1) + λ^k). This gives us:

det(B - λI) = (-1)^k * (λ^k + ak-1λ^(k-1) + ... + a1λ + a0)

Also, by the induction hypothesis, the characteristic polynomials of C0, C1, ..., Ck-1 are (-1)^(k-1) * (a0 + a1λ + ... + ak-2λ^(k-2) + λ^(k-1)).

Substituting these results back into the expression for det(A' - λI), we get:

det(A' - λI) = (100 - λ) * (-1)^k * (λ^k + ak-1λ^(k-1) + ... + a1λ + a0) - (-1)^(k+1) * a0 * (-1)^(k-1) * (a0 + a1λ + ... + ak-2λ^(k-2) + λ^(k-1)) + (-1)^(k+1) * a1 * (-1)^(k-1) * (a0 + a1λ + ... + ak-2λ^(k-2) + λ^(k-1)) - ... - (-1)^(k+1) * ak-1 * (-1)^(k-1) * (a0 + a1λ + ... + ak-2λ^(k-2) + λ^(k-1))

Simplifying this expression, we obtain:

det(A' - λI) = (-1)^(k+1) * (λ^(k+1) + (a0 + a1 + ... + ak-1) * λ^k + (a1 + a2 + ... + ak-1) * λ^(k-1) + ... + ak-1 * λ + ak)

This is equal to (-1)^(k+1) * ((a0 + a1 + ... + ak-1)λ^k + (a1 + a2 + ... + ak-1)λ^(k-1) + ... + ak-1 * λ + (λ^(k+1) + ak))

Therefore, the characteristic polynomial of A' is (-1)^(k+1) * ((a0 + a1 + ... + ak-1)λ^k + (a1 + a2 + ... + ak-1)λ^(k-1) + ... + ak-1 * λ + (λ^(k+1) + ak))

Comparing this with the desired form of (-1)^(k+1) * (ao + a1λ + ... + ak-1λ^(k-1) + λ^k), we can see that the coefficient (ao + a1 + ... + ak-1) matches the coefficient (ak-1) in the desired form.

Therefore, by mathematical induction, the characteristic polynomial of matrix A is (-1)^k * (ao + a1λ + ... + ak-1λ^(k-1) + λ^k), as desired.

To evaluate the integral by reversing the order of integration, we first need to draw the region of integration. From the given limits of integration, we can see that the region is a rectangle with vertices at (0,4), (0,12), (11,4), and (11,12).

Now, we can reverse the order of integration by integrating with respect to y first, and then x. The new limits of integration will be y = 4 to y = 12 and x = 0 to x = 11e^(2y/3).

So, the new integral will be:

∫(0 to 11) ∫(4 to 12) 3y e^(2x/3) dy dx

We can evaluate this integral using integration by parts. Integrating with respect to y gives us:

∫(0 to 11) [3y^2/2 e^(2x/3)] from y = 4 to y = 12

Simplifying this expression gives us:

∫(0 to 11) [36e^(2x/3) - 6e^(8x/3)]/2 dx

Now, integrating with respect to x gives us:

[27e^(2x/3) - 9e^(8x/3)] from x = 0 to x = 11

Substituting these values and simplifying gives us the final answer:

(27e^22/3 - 9e^88/3) - (27 - 9) = 27e^22/3 - 9e^88/3 - 18
