Answer:

70 ounces

Step-by-step explanation:

26÷13=2

so 1 candy bar weighs 2 ounces

35 candy bars will then equal 35×2

35×2=70 ounces

Answer: 70 ounces

Step-by-step explanation:

       First, we will find the weight per bar. We will do this by dividing 26 ounces by 13 bards.

               26 ounces / 13 candy bars = 2 ounces per bar

       Next, we will multiply this value of ounces per bar by 35 candy bards.

               35 candy bards * 2 ounces per bar = 70 ounces

The area inside both the ellipse and the curve is 0.

To compute the area inside the ellipse, we'll apply Green's theorem. First, let's rewrite the equation of the ellipse in a standard form:

x^2/7^2 + y^2/18^2 = 1

This gives us the equation of the ellipse as:

x^2/49 + y^2/324 = 1

Now, we'll find a parametrization for the ellipse using the trigonometric functions. Let:

x(t) = 7cos(t)

y(t) = 18sin(t)

where t is a parameter that ranges from 0 to 2π (a complete cycle).

Next, we'll compute the area using Green's theorem:

∫∫D dxdy = (1/2)∫∂D -ydx + xdy

Substituting the parametrization into the integral:

∫∫D dxdy = (1/2)∫∂D -ydx + xdy

= (1/2)∫[0 to 2π] (-18sin(t))(7cos(t))dt + (7cos(t))(18sin(t))dt

Simplifying the expression:

∫∫D dxdy = (1/2)∫[0 to 2π] -126sin(t)cos(t)dt + 126sin(t)cos(t)dt

= (1/2)∫[0 to 2π] 0 dt

= 0

Therefore, the area inside the ellipse x^2/7^2 + y^2/18^2 = 1 is 0. This result may seem counterintuitive, but it is because the ellipse is symmetric and the positive and negative areas cancel each other out when integrated over the entire ellipse.

Now, let's move on to the second part.

The equation of the curve is given as:

x^2/8^(2/3) + y^2/8^(2/3) = 1

Simplifying this equation:

x^(2/3) + y^(2/3) = 64^(1/3)

To find a parametrization for this curve, let:

x(t) = 8cos^3(t)

y(t) = 8sin^3(t)

where t ranges from 0 to 2π.

Now, using Green's theorem, we'll compute the area inside the curve

∫∫D dxdy = (1/2)∫∂D -ydx + xdy

Substituting the parametrization into the integral:

∫∫D dxdy = (1/2)∫∂D -ydx + xdy

= (1/2)∫[0 to 2π] (-8sin^3(t))(8cos^3(t))dt + (8cos^3(t))(8sin^3(t))dt

Simplifying the expression:

∫∫D dxdy = (1/2)∫[0 to 2π] -64sin^3(t)cos^3(t)dt + 64sin^3(t)cos^3(t)dt

= (1/2)∫[0 to 2π] 0 dt

= 0

Therefore, the area inside the curve x^2/8^(2/3) + y^2/8^(2/3) = 1 is also 0. Similar to the previous case, this result is due to the symmetric nature of the curve, causing the positive and negative areas to cancel each other out when integrated over

Both solutions satisfy the original equation. As a result, there are no extraneous solutions in this case.

To determine the number of extraneous solutions in the given equation, let's simplify it step by step:

Step 1: Let's find the common denominator for the two fractions on the left side of the equation. The common denominator is (2m + 3)(2m - 3).

Step 2: Apply the common denominator to both fractions:

[(2m)(2m - 3)]/[(2m + 3)(2m - 3)] - [(2m)(2m + 3)]/[(2m + 3)(2m - 3)] = 1

Step 3: Simplify the numerators:

[tex][4m^2 - 6m - 4m^2 - 6m]/[(2m + 3)(2m - 3)] = 1[/tex]

[-12m]/[(2m + 3)(2m - 3)] = 1

Step 4: Cancel out common factors:

-12m = (2m + 3)(2m - 3)

[tex]-12m = 4m^2 - 9[/tex]

Step 5: Rearrange the equation:

[tex]4m^2 + 12m - 9 = 0[/tex]

Step 6: Solve the quadratic equation using factoring, completing the square, or using the quadratic formula. Let's use the quadratic formula:

[tex]m = (-b ± √(b^2 - 4ac))/(2a)[/tex]

For our equation, a = 4, b = 12, and c = -9. Substituting these values:

m = (-(12) ± √((12)^2 - 4(4)(-9)))/(2(4))

m = (-12 ± √(144 + 144))/(8)

m = (-12 ± √288)/8

m = (-12 ± 12√2)/8

Simplifying further:

m = (-3 ± 3√2)/2

So, we have two potential solutions for m:

m = (-3 + 3√2)/2  and  m = (-3 - 3√2)/2

Now we need to check if these solutions satisfy the original equation. Let's substitute these values back into the equation:

For m = (-3 + 3√2)/2:

[(2(-3 + 3√2))/(2(-3 + 3√2) + 3)] - [(2(-3 + 3√2))/(2(-3 + 3√2) - 3)] = 1

Simplifying this equation, we find that it holds true.

For m = (-3 - 3√2)/2:

[(2(-3 - 3√2))/(2(-3 - 3√2) + 3)] - [(2(-3 - 3√2))/(2(-3 - 3√2) - 3)] = 1

Simplifying this equation, we also find that it holds true.

Therefore, both solutions satisfy the original equation. As a result, there are no extraneous solutions in this case.

The solution to the given PDE with the provided BCs and ICs involves finding the eigenfunctions and eigenvalues through separation of variables and then using the Fourier series expansion to determine the coefficients that satisfy the initial conditions.

The given partial differential equation (PDE) is a wave equation in one dimension, represented as utt = 25ux x, where u is a function of two variables x and t. This equation describes the behavior of waves propagating in the x-direction.

The boundary conditions (BC) state that u(0,t) = u(1,t) = 0, which means that the function u is zero at both ends of the interval x = 0 and x = 1. These boundary conditions enforce the idea that there are no reflections or transmissions at the boundaries.

The initial conditions (IC) specify the initial behavior of the wave. Here, u(x,0) = 9sin(2πx) represents the initial displacement of the wave, and ut(x,0) = 4sin(3πx) represents the initial velocity of the wave.

To solve this problem, we can use the method of separation of variables. We assume a solution of the form u(x,t) = X(x)T(t), where X(x) represents the spatial component and T(t) represents the temporal component.

By substituting this solution into the wave equation, we obtain two ordinary differential equations: X''(x)/X(x) = T''(t)/(25T(t)) = -λ².

Solving the spatial equation X''(x)/X(x) = -λ², subject to the boundary conditions X(0) = X(1) = 0, we find that the eigenfunctions are Xn(x) = sin(nπx), and the corresponding eigenvalues are λn = nπ.

Solving the temporal equation T''(t)/(25T(t)) = -λ², we obtain Tn(t) = A_nsin(λnt) + B_ncos(λnt), where A_n and B_n are constants determined by the initial conditions.

Finally, we can express the general solution as the superposition of all the eigenfunctions: u(x,t) = Σ[A_nsin(λnt) + B_ncos(λnt)]sin(nπx), where the sum is taken over all possible values of n.

To find the specific solution that satisfies the given initial conditions, we can use the Fourier series expansion of the initial conditions and match the coefficients with the general solution.

The point (-2, 5) translated down 4 units would result in the new coordinates (-2, 1).

When a translation is performed, the entire shape or point is shifted in a specified direction.

In this case, since we are translating down, we need to decrease the y-coordinate of the point by 4 units.

Starting with the original point (-2, 5), we move 4 units downward along the y-axis. Since we are subtracting 4 units from the y-coordinate, the new y-coordinate becomes 5 - 4 = 1.

Therefore, the translated point would be (-2, 1).

This means that the point originally located at (-2, 5) has been shifted downward by 4 units and is now located at (-2, 1).

The x-coordinate remains the same since the translation was only performed along the y-axis.

Green's theorem can be used to evaluate the line integral along the triangular path from (0, 0) to (2, 0) to (2, 1) to (0, 0) of the function xy dx + y^3 dy.

Green's theorem relates a line integral around a closed curve to a double integral over the region enclosed by the curve. The theorem states that the line integral of a vector field F along a simple closed curve C is equal to the double integral of the curl of F over the region D enclosed by C. In this case, we are given the line integral of the function xy dx + y^3 dy along the triangular path.

To evaluate the line integral using Green's theorem, we first need to find the curl of the vector field associated with the function. The curl of F = (P, Q) is given by ∂Q/∂x - ∂P/∂y, where P and Q are the components of the vector field.

In this case, P = xy and Q = y^3. Taking the partial derivatives, we get ∂Q/∂x = 0 and ∂P/∂y = x. Therefore, the curl of F is 0 - x = -x.

Now, we can evaluate the double integral of the curl of F over the region D enclosed by the triangular path. The region D is a triangle with vertices (0, 0), (2, 0), and (2, 1). By integrating -x over this region, we can find the value of the line integral.

Performing the double integral and simplifying the result will give us the final answer for the line integral along the given path using Green's theorem.

The probability of drawing a D, then drawing an H (with replacement) from the given deck is 2/49.

To calculate the probability of drawing a D, then drawing an H, replacing the first card, we need to know the total number of cards in the deck and the number of D and H cards in the deck.

Since you mentioned the deck consists of the letters OHDBOHG, we'll assume there are 7 cards in total.

The probability of drawing a D on the first draw, assuming all cards are equally likely to be drawn, is 1 out of 7 since there is only one D card in the deck.

Since we are replacing the first card, the deck remains the same for the second draw. So, the probability of drawing an H on the second draw, assuming all cards are equally likely to be drawn, is also 1 out of 7 since there is only one H card in the deck.

To find the overall probability, we multiply the probabilities of the individual events:

Probability = (1/7) * (1/7) = 2/49

Therefore, the probability of drawing a D, then drawing an H (with replacement) from the given deck is 2/49.

The joint probability mass function is determined to be p(x,y) = (2/3)xy, the conditional probability p(x > 1 | y = 1) is 1/2, E(X) is 10/3, and E(Y) is 2.

To find the value of k that makes the given function a probability mass function, we need to ensure that the sum of all probabilities over the entire sample space is equal to 1.

Let's calculate the sum of probabilities:

∑∑ p(x, y) = ∑∑ k(xy)

Since the function is defined as zero when x ≠ 1 and 2y ≠ 1, we only need to consider the cases where x = 1 and 2y = 1:

∑∑ p(x, y) = k(1 * y) + k(1 * (1/2))

To make this sum equal to 1, we need:

k(y + 1/2) = 1

Since this equation holds for all values of y, we can choose a value of y that satisfies the equation. Let's choose y = 1:

k(1 + 1/2) = 1

k(3/2) = 1

k = 2/3

So, the value of k that makes the function a probability mass function is 2/3.

Now let's find p(x > 1 | y = 1):

p(x > 1 | y = 1) = p(x = 2 | y = 1) / p(y = 1)

To calculate p(x = 2 | y = 1), we use the joint probability mass function:

p(x = 2 | y = 1) = k(2 * 1) = 2/3

To calculate p(y = 1), we sum the probabilities over all x values:

p(y = 1) = ∑ p(x, 1) = p(1, 1) + p(2, 1) = k(1 * 1) + k(2 * 1) = 2/3 + 2/3 = 4/3

Therefore, p(x > 1 | y = 1) = (2/3) / (4/3) = 1/2.

To find E(X), we need to calculate the expected value of X using the joint probability mass function:

E(X) = ∑∑ x * p(x, y)

= 1 * p(1, 1) + 2 * p(2, 1)

= 1 * (k * 1 * 1) + 2 * (k * 2 * 1)

= 1 * (2/3 * 1 * 1) + 2 * (2/3 * 2 * 1)

= 2/3 + 8/3

= 10/3

Therefore, E(X) = 10/3.

To find E(Y), we need to calculate the expected value of Y using the joint probability mass function:

E(Y) = ∑∑ y * p(x, y)

= 1 * p(1, 1) + 1 * p(1, 2)

= 1 * (k * 1 * 1) + 1 * (k * 1 * 2)

= 1 * (2/3 * 1 * 1) + 1 * (2/3 * 1 * 2)

= 2/3 + 4/3

Diatomic molecules can move through rotation and vibration. Quantum mechanics quantizes energy, and the Schrödinger equation provides solutions for studying molecular energy levels.

When examining molecular energy levels, diatomic molecules exhibit rotational and vibrational motions independent of their center of mass. In quantum mechanics, energy is quantized, meaning it can only be added or subtracted in specific discrete quantities.

The Schrödinger equation provides solutions for various quantum systems. Two solutions, the hydrogen atom and the harmonic oscillator, are particularly useful for studying molecules. The hydrogen atom has a spherically symmetric potential energy, which allows us to determine the allowed values of angular momentum (L) using the equation L^2 = l(l + 1)ℏ^2, where l represents different angular momentum states (l = 0, 1, 2, 3, ...).

Similarly, diatomic molecules have a spherically symmetric potential energy function U(r) = 0 for rotation. As a result, we can utilize the same equation for the allowed angular momentum states as in the case of the hydrogen atom, enabling us to analyze and understand the rotational energy levels of diatomic molecules.

A cutoff of 10% for statistical significance is more lenient compared to the standard 5% cutoff.

What is statistical significance?

Statistical significance is a measure used in hypothesis testing to determine whether an observed result is likely to be due to chance or represents a true effect. It indicates the level of confidence that can be placed in the findings of a study or experiment

Compared to the standard 5% cutoff for statistical significance, a cutoff of 10% would be more lenient or less strict.

In statistical hypothesis testing, the significance level, often denoted as alpha (α), represents the threshold below which the p-value must fall to reject the null hypothesis. The commonly used standard cutoff is 5% (or 0.05), which means that if the p-value is less than 0.05, the result is considered statistically significant, and the null hypothesis is rejected.

When the cutoff is increased to 10% (or 0.10), it means that the threshold for statistical significance is relaxed. In other words, a p-value less than 0.10 would now be considered statistically significant, leading to a higher likelihood of rejecting the null hypothesis. This increased cutoff allows for a wider range of p-values to be considered statistically significant, making it easier to detect effects or relationships.

However, it's important to note that a higher cutoff also increases the chances of a Type I error (rejecting the null hypothesis when it is true). This means there is a higher probability of falsely concluding that there is a significant effect or relationship when it may not actually exist.

Choosing the appropriate significance level depends on the specific context, research field, and the consequences of Type I and Type II errors. Lower significance levels, like 5%, are often used to maintain a more stringent standard and reduce the risk of false positives. However, in certain cases, a higher cutoff like 10% may be suitable, such as in exploratory analyses or when the consequences of Type II errors (failing to detect a true effect) are more severe.

The series converges. To determine the convergence or divergence of the series:

∑[infinity] (−1)^n ln(n) / n^2

We can use the alternating series test. The alternating series test states that if a series is of the form:

∑[infinity] (-1)^n b_n

where b_n > 0 for all n and b_n is a decreasing sequence, then the series converges if the limit of b_n as n approaches infinity is 0.

In the given series, we have b_n = ln(n) / n^2.

First, let's check if b_n is positive for all n. Since ln(n) is positive for n > 1 and n^2 is also positive, the ratio ln(n) / n^2 is positive for n > 1.

Next, we need to show that b_n is a decreasing sequence. To do this, we can consider the ratio of consecutive terms:

b_{n+1} / b_n = [ln(n+1) / (n+1)^2] / [ln(n) / n^2]

= (ln(n+1) / n^2) * (n^2 / (n+1)^2)

= (ln(n+1) / n^2) * (1 / (1+1/n)^2)

Since ln(n+1) is a logarithmic function, it grows at a slower rate than any positive power of n. Therefore, the first term ln(n+1) / n^2 decreases as n increases. The second term (1 / (1+1/n)^2) is always less than or equal to 1.

Thus, the ratio b_{n+1} / b_n is less than or equal to 1 for all n > 1. This shows that the sequence b_n is decreasing.

Now, we need to evaluate the limit of b_n as n approaches infinity:

lim(n->∞) ln(n) / n^2

= lim(n->∞) [ln(n) / n] / n

= (0 / ∞) / ∞ (using L'Hôpital's rule)

= 0

Since the limit of b_n as n approaches infinity is 0, the alternating series test tells us that the series:

To compute the partial sums 3, 4, and 5 for a series, we need to add up the first three, four, and five terms of the series, respectively. Let's say the series is denoted by a_n, where n is the index of the term.

For example, if the series is 1, 2, 3, 4, 5, 6, 7, 8, 9, ... (which is an arithmetic series with a common difference of 1), then the partial sums would be:
- The sum of the first three terms (n=1, 2, 3) is 1 + 2 + 3 = 6.
- The sum of the first four terms (n=1, 2, 3, 4) is 1 + 2 + 3 + 4 = 10.
- The sum of the first five terms (n=1, 2, 3, 4, 5) is 1 + 2 + 3 + 4 + 5 = 15.
To find the sum of the series, we need to take the limit of the partial sums as n goes to infinity. In other words, we need to find the value of:
lim n→∞ ∑_(k=1)^n a_k


Without knowing the actual series, it's hard to give a specific answer to this question. However, the process for computing partial sums and finding the sum of a series is the same for any series, so you can apply the same method to whatever series you are given.

Answer:

The gas with the highest average speed at 350 K is the one with the lowest molar mass. This is because the average speed of a gas molecule is directly proportional to the square root of its temperature and inversely proportional to the square root of its molar mass. So, the gas with the lowest molar mass will have the highest average speed.

Therefore, helium will have the highest average speed at 350 K.

Therefore, the value of the line integral of F · dr over C, using Stokes's theorem, is -10/3 times the square root of 2.

To use Stokes's theorem to evaluate the line integral of the vector field F = 2yi + 3zj + xk over the triangle C, we need to find the curl of F and then calculate the surface integral of the curl over the surface bounded by C.

The curl of F is given by:

∇ × F = (∂Fz/∂y - ∂Fy/∂z)i + (∂Fx/∂z - ∂Fz/∂x)j + (∂Fy/∂x - ∂Fx/∂y)k

Calculating the partial derivatives, we have:

∂Fz/∂y = 0

∂Fy/∂z = 0

∂Fx/∂z = 1

∂Fz/∂x = 3

∂Fy/∂x = 2

∂Fx/∂y = 0

Therefore, the curl of F is:

∇ × F = 3j + 2k

Now, we need to calculate the surface integral of the curl over the surface bounded by C, which is a triangle with vertices (2, 0, 0), (0, 2, 0), and (0, 0, 2).

Using Stokes's theorem, the line integral of F · dr over C is equal to the surface integral of ∇ × F · dS over the surface bounded by C.

The normal vector to the surface is perpendicular to the triangle and has a magnitude of sqrt(2) in this case.

The surface integral becomes:

∬ (∇ × F) · dS = ∬ (3j + 2k) · sqrt(2) dA

The area element dA is given by dxdy.

Integrating over the triangle with bounds as determined by the vertices, we have:

∬ (∇ × F) · dS = ∫[0,2] ∫[0,2-x] (3j + 2k) · sqrt(2) dxdy

Evaluating the integral, we get:

∬ (∇ × F) · dS = ∫[0,2] [(3(2-x) + 2(2-x))] sqrt(2) dx

Simplifying further:

∬ (∇ × F) · dS = ∫[0,2] (10 - 5x) sqrt(2) dx

Integrating, we get:

∬ (∇ × F) · dS = sqrt(2) ∫[0,2] (10x - 5x^2) dx

Evaluating the integral, we have:

∬ (∇ × F) · dS = sqrt(2) [(5x^2/2 - (5x^3)/3)] evaluated from 0 to 2

Plugging in the values, we get:

∬ (∇ × F) · dS = sqrt(2) [(5(2)^2/2 - (5(2)^3)/3) - (5(0)^2/2 - (5(0)^3)/3)]

Simplifying further:

∬ (∇ × F) · dS = sqrt(2) [(10 - 40/3) - 0]

∬ (∇ × F) · dS = sqrt(2) [(30/3 - 40/3)]

∬ (∇ × F) · dS = sqrt(2) [-10/3]

To estimate the numbers using linear approximation, we can use the first-order Taylor expansion, which approximates a function near a point using the function's derivative.

1. Estimate[tex]1.999^4:[/tex]

Let's use the function f(x) =[tex]x^4[/tex] and approximate it near x = 2.

The first derivative of f(x) is f'(x) = [tex]4x^3.[/tex]

Using the linear approximation formula, we have:

f(1.999) ≈ f(2) + f'(2)(1.999 - 2)

         ≈[tex]2^4[/tex] + 4[tex](2^3)[/tex](1.999 - 2)

         ≈ 16 + 4(-0.008)

         ≈ 16 - 0.032

         ≈ 15.968

Therefore, the estimate for[tex]1.999^4 i[/tex]s approximately 15.968.

2. Estimate 5.998^(-1):

Let's use the function f(x) = x^(-1) and approximate it near x = 6.

The first derivative of f(x) is f'(x) =[tex]-1/x^2.[/tex]

Using the linear approximation formula, we have:

f(5.998) ≈ f(6) + f'(6)(5.998 - 6)

           ≈ [tex]6^(-1) \\[/tex]+ [tex](-1/6^2)[/tex](5.998 - 6)

           ≈ 1/6 + (-1/36)(-0.002)

           ≈ 1/6 + 0.00005556

           ≈ 0.1666667 + 0.00005556

           ≈ 0.1667222

Therefore, the estimate for[tex]5.998^(-1)[/tex] is approximately 0.1667222.

3. Estimate sin(0.01):

Let's use the function f(x) = sin(x) and approximate it near x = 0.

The first derivative of f(x) is f'(x) = cos(x).

Using the linear approximation formula, we have:

f(0.01) ≈ f(0) + f'(0)(0.01 - 0)

         ≈ sin(0) + cos(0)(0.01)

         ≈ 0 + 1(0.01)

         ≈ 0.01

Therefore, the estimate for sin(0.01) is approximately 0.01.

4. Estimate [tex]e^(0.01)[/tex]:

Let's use the function f(x) = [tex]e^(x).[/tex] and approximate it near x = 0.

The first derivative of f(x) is f'(x) = [tex]e^(x).[/tex]

Using the linear approximation formula, we have:

f(0.01) ≈ f(0) + f'(0)(0.01 - 0)

         ≈[tex]e^(0)[/tex] + [tex]e^(0)(0.01)[/tex]

         ≈ 1 + 1(0.01)

         ≈ 1.01

Therefore, the estimate for e^(0.01) is approximately 1.01.

These are the linear approximation estimates for the given numbers.

If the total spending of the family is $54,500, then the expected spending on others is $5400.00, The correct option is B.

To calculate the amount spent on "Other," we must determine the fraction of the total expenses corresponding to "Other." According to the graph, "Other" accounts for 1/10 of the total expenses.

To find the amount spent on "Other," we multiply the fraction by the total expenditure:

Amount spent on "Other" = (1/10) * $54,000

To calculate the p-value for a test with the given hypotheses h0:p=0.23 and hΛ:p<0.23, a specific test statistic value is needed.  The p-value represents the probability of obtaining a test statistic as extreme as or more extreme than the observed value, assuming the null hypothesis is true.

Calculating the p-value involves comparing the observed test statistic to the distribution under the null hypothesis. The test statistic could follow different distributions depending on the type of test being conducted (e.g., t-distribution, chi-square distribution, etc.). By determining the appropriate distribution and the critical region defined by the     alternative hypothesis (in this case, hΛ:p<0.23), you can calculate the probability associated with the observed test statistic.

However, since the specific test statistic value is not provided in the question, I recommend referring to statistical software or consulting a statistical table specific to your test statistic and distribution. These resources can help you determine the p-value by comparing the observed test statistic to the distribution and rounding it to the nearest thousandth.

The indicated probabilities from the probability tree are as follows:

(A) P(M∩S) = 0.9 * 0.5 = 0.45

(B) P(R) = 0.9

In the probability tree, we have two branches originating from the initial event, denoted by R and M. The probability of event R occurring is given as 0.9, which means P(R) = 0.9.

Moving down the R branch, we encounter another event denoted by M, with a probability of 0.5. Now, to calculate the probability of the intersection of events M and S, denoted by M∩S, we multiply the probabilities of M and S,

which gives us 0.9 * 0.5 = 0.45.

Therefore, the probability of event M and S both occurring, P(M∩S), is 0.45.

P81 is approximately 73.303. This means that the score of 73.303 separates the bottom 81% from the top 19% of scores on the test.

To calculate P81, which separates the bottom 81% from the top 19%, we need to find the z-score corresponding to the 81st percentile.

The z-score can be calculated using the formula:

[tex]z = (x - μ) / σ[/tex]

Where:

x is the desired percentile (in this case, the 81st percentile)

μ is the mean of the distribution (63.2%)

σ is the standard deviation (11.7)

To find the z-score corresponding to the 81st percentile, we need to find the z-value such that the area under the normal curve to the left of that z-value is 0.81.

Using a standard normal distribution table or statistical software, we can find the z-value corresponding to the 81st percentile. In this case, it is approximately 0.865.

Now, we can solve for x in the z-score formula:

0.865 = (x - 63.2) / 11.7

Rearranging the equation and solving for x:

x - 63.2 = 0.865 * 11.7

x - 63.2 = 10.103

x = 73.303
