A firm's value of the marginal product of labor (VMPL?) is shown in the figure. Suppose the price of the product decreases. Using the line drawing tool, show how the value of the marginal product of labor changes by drawing a new value of the marginal product of labor. Label the line "VMPL?." Carefully follow the instructions above, and only draw the required object.

Ankit enrolled in the EDM course but had to miss a few classes due to mandatory election duty during India’s General Election. During his absence, the class was given an assignment to analyze the relationship between automobile sales (y) and their prices (X). Ankit estimated the following two models to explore this relationship: yi = \beta 1 + \beta 2X + ui (1) logyi = \alpha 1 + \alpha 2 log X + ui (2) a. Ankit is unsure how to interpret the coefficients \beta 2 and \alpha 2 in these models. Can you help Ankit interpret \beta 2 and \alpha 2 in these models? b. After reviewing the models, you notice that an important variable, Income (X2), which could affect automobile sales, is missing. Explain to Ankit the implications of not including a crucial/essential variable in the model.

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part In the sport of roller derby, players must pass a Minimum Skills test, in order to be allowed to participate in bouts. In one part of the test a skater must get 27 laps around the track in 5 minutes. Auntie Matter is a skater for the Reservoir Dolls, a roller derby team in Madison, Wisconsin. She is testing today to show that she can get her 27 in 5. Auntie studies physics, and she decides to determine in advance the minimum centripetal acceleration she will need in order to pass this test. Also, given that she knows the coefficient of friction of her wheels is 0.64 and her mass on skates is 67 kg, she decides to find the maximum number of laps she could get before losing friction and skidding off the track. Auntie chooses to skate Path B, skating in a path that is as close to a circle as possible. Based on the dimensions of a standard roller derby track, this circle will have a radius of 16.3 meters. How many meters will Auntie have to travel in order to do 27 laps? (Please provide an answer before moving to the next part.) The total distance Auntie will have to travel is m
