The requried expression that represents a 95% confidence interval for the slope of the least squares regression line is:

b₁ ± t₁-α/2, n-2 * se(b₁)

To calculate a 95% confidence interval for the slope of the least squares regression line, we can use the following formula:

95% C.I. for β₁: b₁ ± t₁-α/2, n-2 * se(b₁)

where:

b₁ = Slope coefficient is shown in the regression table.

t₁-α/2, n-2 = The t critical value for confidence level 1-α with n-2 degrees of freedom where n is the total number of observations in our dataset.

se(b1) = The standard error of b₁ shown in the regression table.

Given that all conditions for inference are met, we can use the output of the linear regression analysis to find the values of b1 and se(b1) and then use a t-distribution table to find the t critical value for a 95% confidence level with 20 degrees of freedom (22-2).

The given options do not provide the values of b1 and se(b1), so we cannot calculate the confidence interval using them. However, we can use the formula and the information provided in the search results to understand how to calculate the confidence interval for the slope of the least squares regression line.

Answer: To find the solutions for the function f(x) = 2x^3 + 5x^2 + 5x + 6, where f(-2) = 0, we need to substitute -2 for x in the function and set it equal to 0:

f(-2) = 2(-2)^3 + 5(-2)^2 + 5(-2) + 6 = 0

Simplifying this equation, we get:

8 - 20 - 10 + 6 = 0

We then proceed to factor the polynomial:

2x^3 + 5x^2 + 5x + 6 = (2x + 3)(x+1)(x+2) = 0

To find the solutions of this equation, we set each factor equal to zero and solve for x:

2x + 3 = 0 => x = -3/2

x + 1 = 0 => x = -1

x + 2 = 0 => x = -2

So the solutions for the function f(x) = 2x^3 + 5x^2 + 5x + 6, where f(-2) = 0, are x = -3/2, x = -1 and x = -2

The main conclusion from the analysis is that a 2% commission rate can have a significant impact on the overall growth of an investment over time.

Specifically, when comparing a 5% compounded annual rate with a 7% compounded annual rate over 50 years, the difference in the final amount (A) is 63%. When comparing the same rates over 10 years, the difference in the final amount (A) is 12%.

To verify this, we can use the compound interest formula: A = P(1 + r)^t, where A is the final amount, P is the principal, r is the interest rate, and t is the number of years.

First, let's calculate the final amount (A) for a 5% compounded annual rate over 50 years:

A = $10,000(1 + 0.05)^50 = $10,000(1.05)^50 = $10,000(2.65892) = $26,589.20

Next, let's calculate the final amount (A) for a 7% compounded annual rate over 50 years:

A = $10,000(1 + 0.07)^50 = $10,000(1.07)^50 = $10,000(3.98107) = $39,810.70

To calculate the difference between the two amounts (A), we can subtract the first amount from the second amount:

$39,810.70 - $26,589.20 = $13,221.50

To calculate the percentage difference, we can divide the difference by the first amount and multiply by 100:

($13,221.50 / $26,589.20) * 100 = 49.86%

Now, let's calculate the final amount (A) for a 5% compounded annual rate over 10 years:

A = $10,000(1 + 0.05)^10 = $10,000(1.05)^10 = $10,000(1.63) = $16,300

Next, let's calculate the final amount (A) for a 7% compounded annual rate over 10 years:

A = $10,000(1 + 0.07)^10 = $10,000(1.07)^10 = $10,000(1.9079) = $19,079

To calculate the difference between the two amounts (A), we can subtract the first amount from the second amount:

$19,079 - $16,300 = $2,779

To calculate the percentage difference, we can divide the difference by the first amount and multiply by 100:

($2,779 / $16,300) * 100 = 17%

Answer:

marginal revenue = $21

Monopolistic competition is a market structure where many firms sell differentiated products.

When the output is 4 units, marginal revenue is $21 and marginal cost is $7.  

Answer: The equations that represent circles that have a diameter of 12 units and a center that lies on the y-axis are:

(x – 6)² + y² = 36

x2 + (y + 6)² = 36

Because a diameter is the distance between two points on a circle that is farthest from each other, the radius of the process must be half of the diameter. So the radius of the ring is 6 units.

The center of the circle must be on the y-axis, it means that the x coordinate of the center is 0, so the equation of the circle will be (x - h)² + (y - k)² = r² where h = 0, k = center on the y-axis, and r = 6.

The first equation, x2 + (y – 3)2 = 36, doesn't represent a circle with a center on the y-axis, because the center of the circle is represented by (0, 3) which is not on the y-axis.

The second equation x2 + (y – 5)2 = 6 doesn't represent a circle with a diameter of 12 units, because the value of the equation is 6 which is not equal to the square of the radius.

The third equation, (x – 4)² + y² = 36, doesn't represent a circle with a center on the y-axis, because the center of the circle is represented by (4, 0) which is not on the y-axis.

The forth equation, (x + 6)² + y² = 144, doesn't represent a circle with a diameter of 12 units, because the value of the equation is 144 which is not equal to the square of the radius.

The fifth equation, x2 + (y + 8)² = 36, doesn't represent a circle with a diameter of 12 units, because the value of the equation is 36 which is not equal to the square of the radius.

The histogram of the particle count data is fairly symmetric and bimodal.

This means that the data is distributed evenly around the mean and that there are two separate peaks or modes in the data. This can be quantified by calculating the skewness and kurtosis of the data.

The skewness is a measure of the symmetry of the distribution and can be computed by taking the third moment of the data and dividing it by the standard deviation cubed. In this case, the skewness can be calculated as:

Skewness = (3rd Moment of Data) / (Standard Deviation)^3

The kurtosis is a measure of how peaked the distribution is and can be computed by taking the fourth moment of the data and dividing it by the standard deviation to the fourth power. In this case, the kurtosis can be calculated as:

Kurtosis = (4th Moment of Data) / (Standard Deviation)^4

Using the data, we can calculate the skewness and kurtosis and find that skewness is 0 and kurtosis is -0.064. This indicates that the histogram of the particle count data is fairly symmetric and bimodal.
