Given:  Population mean IQ = 112Population standard deviation IQ = 50.62Sample size (n) = 30To find: Distribution of the sample mean IQ

The Central Limit Theorem states that for a large sample size, the distribution of sample means will be approximately Normal with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size . Let's calculate the standard deviation of the sample mean IQ:

Standard deviation of sample mean IQ = (Population standard deviation IQ) / √n= 50.62 / √30= 9.241 (approx.)Therefore, the distribution of the sample mean IQ is approximately Normal, with mean 112 and standard deviation 9.241. The correct option is (d).

Answer:

Domain: (-∞,+∞)

Range: (-∞,1)

y-intercept: (0,2)

Asymptote: I am not sure (sorry) I know they can be solved using the equation n(x)=0

Step-by-step explanation:

Domain: the set of all x-values

- this graph has arrows which means the domain is from -∞ to +∞ (-∞,+∞)

Range: the set of all y-values

- the graph extend continuously on the negative side so -∞ and it stops at 1 on the positive side  (-∞,1)

Y-intercept: this point is where the graph crosses the y-axis, this is at (0,2)

The statements that are TRUE with regard to a data set's measures of Central Tendency, Dispersion, and Paired Observations are the following:In a very small set of data, i.e. small n, the Sample Standard Deviation is generally smaller than its Population Standard Deviation.

It is possible for the value of the Correlation between a set of paired observations to be greater than 1.In a set of paired observations of X and Y, if the Correlation is 0.75, then as the values of X increases (decreases), the values of Y also generally increases (decreases) in the same direction.In a very large set of data, i.e. large n, the Standard Deviation is a better measurement than Range.Why these statements are true?In a very small set of data, the Sample Standard Deviation is generally smaller than its Population Standard Deviation because when the sample size is smaller, there is less dispersion and thus the value of the sample standard deviation is generally smaller than that of the population standard deviation.It is possible for the value of the Correlation between a set of paired observations to be greater than 1 because the correlation coefficient r ranges from -1 to 1, inclusive of both endpoints.

However, it is practically impossible to get a value of r outside this range in a real dataset.In a set of paired observations of X and Y, if the Correlation is 0.75, then as the values of X increases (decreases), the values of Y also generally increases (decreases) in the same direction. This is because 0.75 is a strong positive correlation indicating that as the value of one variable increases, the value of the other variable also increases.In a very large set of data, i.e. large n, the Standard Deviation is a better measurement than Range because the standard deviation takes into account all values in the dataset and is less sensitive to outliers as compared to the range. On the other hand, the range only considers the minimum and maximum values of the dataset and thus is less informative.

Answer:

A

Step-by-step explanation:

To solve the equation 4cos^2(x)tan(x) - 2tan(x) = 0 on the interval [0°, 360°), we can use algebraic manipulations and trigonometric identities. Let's simplify the equation step by step:

Start with the given equation: 4cos^2(x)tan(x) - 2tan(x) = 0.

Factor out the common term tan(x): tan(x)(4cos^2(x) - 2) = 0.

Set each factor equal to zero and solve separately:

a) tan(x) = 0:

Since tan(x) is zero at x = 0°, 180°, and 360°, we have x = 0°, 180°, 360° as solutions.

b) 4cos^2(x) - 2 = 0:

Add 2 to both sides: 4cos^2(x) = 2.

Divide by 4: cos^2(x) = 1/2.

Take the square root: cos(x) = ±√(1/2).

To find the values of x in the interval [0°, 360°), we need to consider both the positive and negative square root:

cos(x) = √(1/2):

x = 45°, 315° (since cos(45°) = cos(315°) = 1/√2)

cos(x) = -√(1/2):

x = 135°, 225° (since cos(135°) = cos(225°) = -1/√2)

Therefore, the solutions to the equation 4cos^2(x)tan(x) - 2tan(x) = 0 on the interval [0°, 360°) are: x = 0°, 45°, 135°, 180°, 225°, 315°, and 360°.

The initial value of X can be determined using compound interest calculations. X is invested in an account with a nominal annual interest rate of 2.5%, compounded on a monthly basis, for a period of five years. After the initial period, X is then transferred to another account with a nominal annual interest rate of 3.2%, compounded on a quarterly basis, for a total duration of eight years. The approximate value of X at the end of this investment period is $6,573.83.

To solve for X, we will substitute the first equation into the second equation and solve for X. Let's proceed with the calculations:

The first equation is: FV = X(1 + 0.025/12)^(12*5)

The second equation is: $10,000 = X(1 + 0.032/4)^(48)(1 + 0.025/12)^(125)

We can substitute the first equation into the second equation:

$10,000 = [X(1 + 0.025/12)^(125)] * (1 + 0.032/4)^(48)

$10,000 = X * (1 + 0.025/12)^(125) * (1 + 0.032/4)^(48)

Now we can simplify the equation:

$10,000 = X * (1.002083)^60 * (1.008)^32

Divide both sides of the equation by [(1.002083)^60 * (1.008)^32] to solve for X:

X = $10,000 / [(1.002083)^60 * (1.008)^32]

Using a calculator, we can find the value of X:

X ≈ $10,000 / (1.138877 * 1.335893)

X ≈ $10,000 / 1.521364

X ≈ $6,573.83

Therefore, the value of X is approximately $6,573.83.

The true solution to the equation is x ≈ 0.688. By simplifying the equation and solving for x, we find the approximate value.

To find the true solution to the equation 3ln(2ln8) = 2ln(4x)x = 1x = 2x = 4x = 8, we need to simplify the equation and solve for x.

First, let's break down the equation step by step:

3ln(2ln8) = 2ln(4x)x = 1x = 2x = 4x = 8

By simplifying each expression, we have:

3ln(ln8) = 2ln(4x)x = x = 2x = 4x = 8

Now, let's focus on the middle expression, 2ln(4x)x. Using the properties of logarithms, we can rewrite it as:

ln((4x)^2) = x

Simplifying further:

ln(16x^2) = x

Exponentiating both sides:

16x^2 = e^x

This is a transcendental equation that cannot be solved algebraically. However, using numerical methods or a graphing calculator, we find the approximate solution:

x ≈ 0.688

Therefore, the true solution to the equation is x ≈ 0.688.

Step-by-step explanation:

The mode is the number that appears the most in the data set. 102 appears 3 times while the others only once

The x-coordinate of the endpoint of the line segment is 2.

The y-coordinate of the endpoint is -6.

To find the x-coordinate of the endpoint of the line segment, we can use the midpoint formula.

Given that one endpoint is at (10, 12) and the midpoint is at (6, 9), we can denote the coordinates of the other endpoint as (x, y).

Using the midpoint formula, we have:

x-coordinate of the endpoint = 2 * x-coordinate of the midpoint - x-coordinate of the known endpoint

x = 2 * 6 - 10

x = 12 - 10

x = 2

To find the y-coordinate of the endpoint of the line segment, we can use the midpoint formula. We know that the midpoint of the line segment is (6, 9) and one endpoint is (10, 12).

Let the coordinates of the other endpoint be (x, y). Using the midpoint formula, we can set up the following equation:

(10 + x) / 2 = 6

Simplifying the equation, we have:

10 + x = 12

Subtracting 10 from both sides:

x = 2

Therefore, the x-coordinate of the endpoint is 2. Now, we need to find the y-coordinate. Since we know that the endpoint is (2, y), we can use the given endpoint (10, 12) to find the y-coordinate:

12 + y / 2 = 9

Subtracting 12 from both sides:

y / 2 = -3

Multiplying both sides by 2:

y = -6

The company have sold 50 GMC and 125 Honda for this profit.

Let the number of GMC sold be x and the number of Honda sold be y.

Then:

[tex]x + y = 175[/tex]----------------------(1)

GMC: Profit on one car sold = $300

Therefore, the total profit on x GMC cars sold = $300x

Honda: Profit on one car sold = $450

Therefore, the total profit on y Honda cars sold = $450y

Total profit on x GMC and y Honda sold = $60,750

Therefore, we can write:

[tex]300x + 450y = 60,750[/tex]----------------(2)

Multiplying (1) by 450 and subtracting it from (2) multiplied by 100, we get:

[tex]-150x = 7,500⇒ x = 50[/tex]

Substituting the value of x in (1), we get:

[tex]y = 175 - 50= 125[/tex]

Therefore, the number of GMC sold is 50 and the number of Honda sold is 125.
