The number of voters that should be sampled for a confidence interval depends on the desired level of confidence and the margin of error.

A larger sample size generally leads to a smaller margin of error and a higher level of confidence in the accuracy of the results. However, the relationship between sample size and margin of error is not linear, meaning that doubling the sample size will not necessarily halve the margin of error.
To calculate the required sample size, a formula can be used that takes into account the margin of error, level of confidence, and population size.
the number of voters that should be sampled for a confidence interval depends on several factors and cannot be determined without more information.
To determine the required sample size, you can use the following formula:
n = (Z^2 * p * (1-p)) / E^2

Where:
- n is the sample size
- Z is the Z-score (usually 1.96 for a 95% confidence interval)
- p is the estimated proportion of the population (usually 0.5 for the worst-case scenario)
- E is the margin of error (in decimal form)

Hence, without the specific margin of error, we cannot provide the exact sample size needed.

Step-by-step explanation:

The volume of cube with a side length of 5 meters is 125 cubic meters, while volume of cube with side length of 4 meters is 64 cubic meters. The difference between the volumes of two cubes is 61 cubic meters.

The volume of a cube is given by V = \(s^3\), where s is the side length of the cube. To find the difference between the volumes of two cubes, we can subtract the smaller volume from the larger volume.

So, the volume of the cube with side length 5 meters is V1 = \(5^3\) = 125 cubic meters, and the volume of the cube with side length 4 meters is V2 = \(4^3\) = 64 cubic meters.

The volume of a cube is given by \(s^3\), where s is the length of the side of the cube. The volume of a cube with a side length of 5 meters is \(5^3\) = 125 cubic meters, and the volume of a cube with a side length of 4 meters is \(4^3\) = 64 cubic meters.

The difference in volumes is V1 - V2 = 125 - 64 = 61 cubic meters. Therefore, the difference in volumes of the two cubes is 61 cubic meters.

Answer:

y = ⅔x - 5

Step-by-step explanation:

The line that is parallel to 2x - 3y = 24, would have the same slope as the line, 2x - 3y = 24.

Rewrite;

2x - 3y = 24

-3y = -2x + 24

Divide both sides by -3

y = ⅔x - 8

Thus, the slope of 2x - 3y = 24 is ⅔.

Therefore the line that is parallel to 2x - 3y = 24, will have a slope (m) of ⅔.

Using point-slope form, we can generate an equation that passes through (-3, -7) and is parallel to 2x - 3y = 24.

Thus, substitute (a, b) = (-3, -7) and m = ⅔ into y - b = m(x - a)

Therefore:

y - (-7) = ⅔(x - (-3))

y + 7 = ⅔(x + 3)

Rewrite in slope-intercept form.

Multiply both sides by 3

3(y + 7) = 2(x + 3)

3y + 21 = 2x + 6

3y = 2x + 6 - 21

3y = 2x - 15

Divide both sides by 3

y = ⅔x - 5

At least 5 expected observations in each cell in order to apply the chi-square test of independence, we prefer to have at least 5 expected observations in each cell. The correct answer is c.

The chi-square test of independence is a statistical method used to determine whether two categorical variables are independent or associated with each other.

To apply this test, it is preferred to have at least 5 expected observations in each cell of the contingency table. The expected frequency is calculated based on the assumption of independence between the two variables.

If the expected frequency is less than 5 in any cell, the chi-square test may not be valid and alternative methods, such as Fisher's exact test, should be considered. Having a sufficient sample size can also improve the accuracy and reliability of the test results.

Suppose we've got cosine of angle A and B measurements.

Then, we have:

sin(B)

\(\cos(A+B) = \cos(A)\cos(B) - \sin(A)\sin(B)\)

We are given that;

An identity is an equation that is true for all values of the variable.

The following three options are identities:

sin(x)(cot(x) + tan(x)) = sec(x)

csc^2(x) + sec^2(x) = 1

cos(2x) - sin(2x) = 1 - 2sin^2(x)

fxy = ∂^2f/∂x∂y = 80xy^3 - 105x^2y^4 is the second-order partial derivative of f(x, y).

To find fxy, we need to take the partial derivative of f(x, y) with respect to x and then with respect to y. Let's calculate it step by step: Given: f(x, y) = 10x^2y^4 - 7x^3y^5. Take the partial derivative of f(x, y) with respect to x (treating y as a constant): ∂f/∂x = ∂/∂x (10x^2y^4) - ∂/∂x (7x^3y^5). Differentiating each term: ∂/∂x (10x^2y^4) = 20xy^4, ∂/∂x (7x^3y^5) = 21x^2y^5

Therefore, ∂f/∂x = 20xy^4 - 21x^2y^5. Take the partial derivative of ∂f/∂x with respect to y (treating x as a constant): ∂/∂y (20xy^4 - 21x^2y^5). Differentiating each term: ∂/∂y (20xy^4) = 80xy^3, ∂/∂y (-21x^2y^5) = -105x^2y^4. Therefore, ∂f/∂x = 80xy^3 - 105x^2y^4. Thus, fxy = ∂^2f/∂x∂y = 80xy^3 - 105x^2y^4 is the second-order partial derivative of f(x, y).

Step-by-step explanation: I used substitution

The function f(x) = x² - 1/x + 1, with domain [0, ∞), does not have an absolute maximum on its domain, but this does not contradict the extreme value theorem.

The extreme value theorem states that if a real-valued function f is continuous on a closed interval [a, b], then f must have both an absolute maximum and an absolute minimum on that interval.

However, the theorem does not apply to functions that have an open interval as their domain, such as f(x) = x² - 1/x + 1 with a domain of [0, ∞).

In this case, f(x) approaches infinity as x approaches 0, but it does not have a maximum value within the given domain. The lack of an absolute maximum for f(x) on [0, ∞) is consistent with the behavior of the function, and it does not violate the extreme value theorem since the domain is not a closed interval.

Therefore, the function f(x) = x² - 1/x + 1, defined on [0, ∞), lacks an absolute maximum, but this does not violate the extreme value theorem.

B. setl 23 47: This option is incorrect because setl is used to set a byte to 1 if the Less flag (SF≠OF) is set, but the given values of a and b are 23 and 47, respectively, so it does not satisfy the condition for setl to be set.

C. sete 23 23: This option is incorrect because sete is used to set a byte to 1 if the Zero flag (ZF=1) is set, but the given values of a and b are 23 and 23, respectively, so it does not satisfy the condition for sete to be set.

D. setne 23 47: This option is correct. setne is used to set a byte to 1 if the Zero flag (ZF=0) is not set, which means the values of a and b are not equal. In this case, the given values of a and b are 23 and 47, respectively, so they are not equal, and setne should be used.

The mean of the sampling distribution of sample means is \(\mu \bar{x}\)=80 and the standard error is \(\sigma\)/√n = 2.5.

The mean of the sampling distribution of sample means is the same as the population mean, which is given as μ=80. This means that on average, the sample means will be equal to the population mean.

The standard error of the sampling distribution of sample means is given by the formula \(\sigma\)/√n, where \(\sigma\) is the population standard deviation and n is the sample size. In this case, \(\sigma\)=20 and n=64, so the standard error is:

\(\sigma\)/√n = 20/√64 = 2.5.

The standard error represents the amount of variability or dispersion that we can expect to see in the sample means. A smaller standard error indicates that the sample means are more tightly clustered around the population mean.

In summary, the mean of the sampling distribution of sample means is \(\mu \bar{x}\)=80, and the standard error is \(\sigma\)/√n = 2.5.
