The mean of the sampling distribution of their average score is 495.

The standard deviation of the sampling distribution of their average score is 1.80

To find the mean of the sampling distribution of the average score (x), we can use the formula:

Mean of sampling distribution = Population mean = 495

Therefore, the mean of the sampling distribution of their average score is 495.

To find the standard deviation of the sampling distribution of the average score, we can use the formula:

Standard deviation of sampling distribution = Population standard deviation / √(sample size)

Given that the population standard deviation is 10.8 and the sample size is 36, we can calculate the standard deviation of the sampling distribution as follows:

Standard deviation of sampling distribution = 10.8 / √36 = 10.8 / 6 = 1.80

Therefore, the standard deviation of the sampling distribution of their average score is 1.80 (rounded to two decimal places).

To calculate the optimal profit, we need to find the value of D when the total cost is \($30,500\) and then substitute it into the given equation.

To find D, we can rearrange the equation to solve for D: Given:\(p = 180 - 0.2D\) and total cost =\($30,500\) Now, substitute the total cost ($30,500) into the equation to find D:

Since D cannot be negative in this context, it means that the given equation is not applicable for a total cost of \($30,500\). it is not possible to calculate the optimal profit using the given equation and the total cost of \($30,500\).

Therefore, the series does not satisfy the necessary condition for convergence, which states that the terms should approach zero.

To determine whether the series converges or diverges, we need to examine the behavior of the terms as the series progresses. Let's analyze the given series:

=2/5 - 2/6 + 2/7 - 2/8 + 2/9

We can rewrite the series by grouping the terms:

=(2/5 - 2/6) + (2/7 - 2/8) + 2/9

To determine the convergence or divergence of the series, we need to evaluate the limit of the terms as the series progresses.

Term 1: 2/5 - 2/6

= (12 - 10)/30

= 2/30

= 1/15

Term 2: 2/7 - 2/8

= (16 - 14)/56

= 2/56

= 1/28

Term 3: 2/9

As we can see, the terms are positive and decreasing as the series progresses. However, the terms do not approach zero.

Options B, C, and D (Expected Utility, Maximin, and Minimax Regret) are decision-making criteria used in different contexts, but they are not specifically related to calculating ROI.

The calculation that should be used when calculating Return on Investment (ROI) is option A: Expected Monetary Value.

ROI is a financial metric that measures the profitability of an investment by comparing the gain or loss from the investment relative to its cost. It is typically expressed as a percentage.

To calculate ROI, the expected monetary value of the investment is considered. It takes into account the potential gains or losses associated with the investment and the probabilities of those outcomes. By multiplying the potential outcomes by their respective probabilities and summing them up, the expected monetary value can be calculated.

The given problem is categorized according to the parameter being estimated, which is the "difference of proportions p1−p2."The calculated difference of proportions p1−p2 is 0.0542.

Given, a random sample of 89 people were asked the voter registration question face-to-face. Of those sampled, eighty respondents gave accurate answers. Another random sample of 84 people was asked the same question during a telephone interview. Of those sampled, seventy-five respondents gave accurate answers.

Assume that the samples are representative of the general population. Categorize the problem according to the parameter being estimated: proportion p, mean μ, a difference of means μ1−μ2, or difference of proportions p1−p2.In this problem, we are comparing the proportion of accurate answers from face-to-face interviews (p1) to that of telephone interviews (p2).

Therefore, the parameter being estimated is the "difference of proportions p1−p2."Calculating the difference of proportions:p1 = 80/89 = 0.8989p2 = 75/84 = 0.8929p1 - p2 = 0.8989 - 0.8929 = 0.0060The difference of proportions p1−p2 is 0.0060 or 0.6%. Thus, the sample data suggests that the proportion of accurate voter registration responses is slightly higher among those interviewed face-to-face.

The proportions of accurate responses for the face-to-face and telephone interviews are 0.8989 and 0.8929, respectively.

a) i. μ1−μ2: There is no specific information given in the problem that requires calculating the difference of means.

ii. μ: There is no specific information given in the problem that requires calculating the mean.

iii. p: The problem involves estimating the proportion of registered voters.

iv. p1−p2: There is no specific information given in the problem that requires calculating the difference of proportions.

The accuracy of response in face-to-face and telephone interviews is being compared.

For the face-to-face interview:

Sample size (n1) = 89

Number of accurate responses (x1) = 80

For the telephone interview:

Sample size (n2) = 84

Number of accurate responses (x2) = 75

To estimate the proportion of accurate responses for each method, we calculate the sample proportions:

p1 = x1/n1

p2 = x2/n2

p1 = 80/89

p2 = 75/84

Simplifying the calculations:

p1 ≈ 0.8989

p2 ≈ 0.8929

Therefore, the estimated proportions of accurate responses for the face-to-face and telephone interviews are 0.8989 and 0.8929, respectively.

Answer:

9/5

Step-by-step explanation:

If we want to know the amount of times the fraction 5/3 can go into 3, you would need to set up the equation 5/3x = 3.

(3/5)*(5/3x) = (3/5)*(3)

x = 9/5

The solutions to the quadratic equation \(2x^2 + 6x - 1 = 0\), obtained by completing the square, are x = -3 + √10 and x = -3 - √10.

To solve the quadratic equation\(2x^2 + 6x - 1 = 0\)by completing the square, follow these steps:

Ensure that the coefficient of \(x^2\) is 1. In this case, it is already 2, so we don't need to make any changes.

Move the constant term to the other side of the equation. Add 1 to both sides:

\(2x^2 + 6x = 1\)

Divide the coefficient of x by 2 and square it. In this case, (6/2)^2 = 9.

Add the result from step 3 to both sides of the equation:

\(2x^2 + 6x + 9 = 1 + 9\)

Simplifying, we get:

\(2x^2 + 6x + 9 = 10\)

Write the left side of the equation as a perfect square trinomial. In this case, it is \((x + 3)^2.\)

\((x + 3)^2 = 10\)

Take the square root of both sides:

\(√[(x + 3)^2] = ±√10\)

Simplifying:

\(x + 3 = ±√10\)

Solve for x by subtracting 3 from both sides:

x = -3 ± √10

So, the solutions to the quadratic equation \(2x^2 + 6x - 1\)= 0, obtained by completing the square, are x = -3 + √10 and x = -3 - √10.

Step-by-step explanation:

Answer:

51 cm^2

Step-by-step explanation:

the formula for area of an icoselese triangle is
A = b * h / 2
h is a line from the angle where the 5 and 5 intersect to the middle of the third line
You can find h using the pythagoran theorm with the 5 being the hypotenuse and the a being half the third line

4^2 + b^2 = 5^2
16 + b^2 = 25
b = 3, so h = 3, so now
A = 8 * 3 / 2
A = 24 / 2
A = 12 cm^2

now we have the triangle, just multiply that by 2 (top and bottom)
12 * 2 = 24

sides
8 * 1.5 = 12
5 * 1.5 * 2 = 15

now add all of it
15 + 12 + 24 = 51

Answer:

75

Step-by-step explanation:

Let n stand-in for "number"

"If 13 is added to a number," so: n + 13

"and the sum is multiplied by three," so: 3(n+13)

"The result is," so:  3(n+13) =

"7 times the number decreased by 9,"  so:  3(n+13) = 7n - 9

Now you can simply by moving numbers across the equal sign:

3n + 39 = 7n - 9

39 = 4n - 9 (take 3n off from both sides)

48 = 4n (add 9 onto both sides)

12 = n

And then check:

3(12 + 13) = 7(12) - 9

3 x 25 = 7 x 12 - 9
