Answer; Ans. Option 1: is correct answer.

Use Cramer's rule to find the solutions for x.y and z given the following equations: 5x - 6y + 4z = 10 3x + 2y - z = 15 2x +y - 5z = 20 x = 4.0944 O. y = 0.1968 z = -2.322 x = - 4.0944 O I. V = -0.1968 z = 2.322 x = -2.322 O I.V = 0.1968 z = 4.0944 x = -2.0614 %3! ON.V = 0.1628 z = - 1.312

Use Cramer's rule to find the solutions for x.y and z given the following equations: 5x - 6y + 4z = 10 3x + 2y - z = 15 2x +y - 5z = 20 x = 4.0944 O. y = 0.1968 z = -2.322 x = - 4.0944 O I. V = -0.1968 z = 2.322 x = -2.322 O I.V = 0.1968 z = 4.0944 x = -2.0614 %3! ON.V = 0.1628 z = - 1.312

4- The manager of Collins Import Autos believes the number of cars sold in a day(Q) depends on two factors: (1) the number of hours the dealership is open (H) and (2) the number of salespersons working that day (S ). After collecting data for two months (53 days), the manager estimates the following log-linear model: Q = aHbSc ----- a. Explain how to transform this log-linear model into a linear form that can be estimated using multiple regression analysis. b. How do you interpret coefficients b and c? If the dealership increases the number of salespersons by 20 percent, what will be the percentage increase in daily sales? c. Test the overall model for statistical significance at the 5 percent significance level.
