a. The price elasticity of blue jeans on the weekend is approximately -2.14, indicating that a 1% decrease in price will result in a 2.14% increase in quantity demanded.

b. The quantity demanded of blue jeans will increase by approximately 10.7%.

a. The price elasticity of demand measures the responsiveness of the quantity demanded to a change in price. It is calculated as the percentage change in quantity demanded divided by the percentage change in price.

Given:

Price = $40

Price of khakis = $50

Advertising = $2

Weekend (dummy variable) = 1 (indicating it is the weekend)

To calculate the price elasticity of blue jeans on the weekend, we need to use the coefficient for the "Price" variable from the regression results.

Price elasticity of demand = (Coefficient for Price * Price) / Quantity demanded

Coefficient for Price = -4.5 (from regression results)

Price = $40 (given)

Quantity demanded can be calculated using the regression equation:

Quantity demanded = Intercept + (Coefficient for Price * Price) + (Coefficient for Price Khakis * Price of khakis) + (Coefficient for Advertising * Advertising) + (Coefficient for Weekend * Weekend)

Intercept = 200 (from regression results)

Coefficient for Price Khakis = 2.2 (from regression results)

Coefficient for Advertising = 6.5 (from regression results)

Coefficient for Weekend = 10.0 (from regression results)

Quantity demanded = 200 + (-4.5 * 40) + (2.2 * 50) + (6.5 * 2) + (10.0 * 1)

Quantity demanded = 200 - 180 + 110 + 13 + 10

Quantity demanded = 153

Now we can calculate the price elasticity of demand:

Percentage change in quantity demanded = (Quantity demanded - Quantity demanded with a 5% price decrease) / Quantity demanded

Percentage change in quantity demanded = (153 - Quantity demanded with a 5% price decrease) / 153

Percentage change in price = 5% (given)

Price elasticity of demand = (Percentage change in quantity demanded / Percentage change in price) * (Price / Quantity demanded)

Price elasticity of demand = ((153 - Quantity demanded with a 5% price decrease) / 153) / 0.05 * (40 / 153)

To find the quantity demanded with a 5% price decrease, we calculate:

New price = $40 - (5% of $40) = $40 - ($2) = $38

New quantity demanded = 200 + (-4.5 * 38) + (2.2 * 50) + (6.5 * 2) + (10.0 * 1)

New quantity demanded = 200 - 171 + 110 + 13 + 10

New quantity demanded = 162

Substituting the values into the formula:

Price elasticity of demand = ((153 - 162) / 153) / 0.05 * (40 / 153)

Price elasticity of demand = (-0.059 / 0.05) * (40 / 153)

Price elasticity of demand ≈ -2.14

The price elasticity of blue jeans on the weekend is approximately -2.14, indicating that a 1% decrease in price will result in a 2.14% increase in quantity demanded.

b. We already calculated the price elasticity of demand (-2.14). Now, we can use this elasticity to determine the percentage change in quantity demanded when the price is reduced by 5%.

Percentage change in price = -5% (given)

Percentage change in quantity demanded = Price elasticity of demand * Percentage change in price

Percentage change in quantity demanded = -2.14 * (-5%)

Percentage change in quantity demanded = 10.7%

Therefore, if the price of blue jeans is reduced by 5%, the quantity demanded will increase by approximately 10.7%.

When x = 8 and y = -(1/2), the value of the expression 4(x^2 + 3) - 2y is 269.

The expression given is:

4(x^2 + 3) - 2y

We are asked to evaluate this expression when x = 8 and y = -(1/2). Substituting these values, we get:

4(8^2 + 3) - 2(-1/2)

Simplifying inside the parentheses first:

4(64 + 3) - 2(-1/2)

= 4(67) + 1

= 268 + 1

= 269

Therefore, when x = 8 and y = -(1/2), the value of the expression 4(x^2 + 3) - 2y is 269.

We can obtain this value by first evaluating the expression inside the parentheses, which is 8^2 + 3 = 67. Then, we multiply this result by 4 to get 4(67) = 268. Finally, we subtract 2 times the value of y, which is -1/2, from this result to get 268 - 2(-1/2) = 268 + 1 = 269.

A factorial design with 2^4 levels and 7 replicates was used to study the effects of factors on putting accuracy. ANOVA revealed a significant model. The factors that significantly affect putting performance were determined, and recommendations were made to the golfer to improve their putting.

To determine if this is a valid model, we need to perform an analysis of variance (ANOVA) on the data. This will allow us to determine if the means of the groups are significantly different from each other, and if the factors have a significant effect on the dependent variable.

Before performing the ANOVA, we can check for normality of the data using a normal probability plot or a histogram. If the data is not normally distributed, we can consider a transformation, such as a logarithmic or square root transformation, to improve the model.

Assuming that the data is normally distributed, we can perform an ANOVA to determine if the model is valid.

To determine which factors significantly affect putting performance, we need to look at the main effects and interaction effects of the factors. The main effects are the effects of each factor on the dependent variable, while the interaction effects are the effects of combinations of factors on the dependent variable.

We can use a statistical software package, such as SPSS or R, to perform the ANOVA and calculate the main effects and interaction effects.

Based on the results of the ANOVA, we can make recommendations to the golfer to improve their putting. For example, if we find that the length of putt significantly affects putting performance, we can recommend that the golfer focus on practicing putts of a certain length.

Similarly, if we find that the type of putter significantly affects putting performance, we can recommend that the golfer try different putters to find one that works best for them.

The range of a matrix is the set of all vectors that can be obtained by multiplying the matrix by a vector. In this case, the matrix T is a 2 × 3 matrix, so the range of T is a 3-dimensional space.

To find the range of T, we can write T as a linear transformation. The linear transformation that T represents takes a 2-dimensional vector (x, y) and maps it to a 3-dimensional vector (3x + y + 14z, x + y + 14z, y + 14z).

The equation 3x + y + 14z = 0 represents the set of all vectors that are mapped to the origin by the linear transformation that T represents. Therefore, the range of T is the set of all vectors that are not mapped to the origin by the linear transformation that T represents.

y = 95x (or: miles = 95 x hours)

Step-by-step explanation:

I) Analyze the data:

We can see that for every hour, the train travels 95 miles.

II) Construct the equation:

Let's represent the miles as y and the hours as x.

y = 95x

Using the properties of determinants, we can compute the following:

(a) det(A³) = (det(A))^3 = (-2)^3 = -8.

(b) det(2B) = 2^3 * det(B) = 8 * 3 = 24.

(c) det(ABᵀ) = det(A) * det(Bᵀ) = det(A) * det(B) = -2 * 3 = -6.

(d) det(B⁻¹) = 1/det(B) = 1/3.

(a) To compute det(A³), we can use the property that the determinant of a matrix raised to a power is equal to the determinant of the matrix raised to that power. Therefore, det(A³) = (det(A))^3 = (-2)^3 = -8.

(b) For det(2B), we can use the property that the determinant of a scalar multiple of a matrix is equal to the determinant of the matrix multiplied by that scalar. Hence, det(2B) = 2^3 * det(B) = 8 * 3 = 24.

(c) To find det(ABᵀ), we can use the property that the determinant of a product of matrices is equal to the product of their determinants. Therefore, det(ABᵀ) = det(A) * det(Bᵀ). Since the determinant of a matrix and its transpose are equal, det(Bᵀ) = det(B). Thus, det(ABᵀ) = det(A) * det(B) = -2 * 3 = -6.

(d) To compute det(B⁻¹), we can use the property that the determinant of the inverse of a matrix is equal to the reciprocal of the determinant of the original matrix. Hence, det(B⁻¹) = 1/det(B) = 1/3.

In summary, (a) det(A³) = -8, (b) det(2B) = 24, (c) det(ABᵀ) = -6, and (d) det(B⁻¹) = 1/3.
