In her free time, Pam likes to practice dancing while preparing for a math tournament. She spends a total of 80 minutes every day practicing dance and math. To help her concentrate better, the number of minutes Pam dances is twenty more than the number of minutes she practices math. Let D represent the number of minutes Pam dances and M represent the number of minutes she practices math. Part A: Write a pair of linear equations to show the relationship between the number of minutes Pam dances (D) and the number of minutes she practices math (M). (3 points) Part B: Solve the system algebraically and show your solving steps? (5 points) Part C: Write the solution statement representing the answer to this problem. (2 points) (10 points)

The investigating team suspected that there were differences in the cost of repairing cars in workshop i and workshop ii. the investigating team suspected that the costs raised by workshop i were greater than workshop ii. for that they tested the repair of 15 cars in each workshop to see the cost of repairs. the decision of the right hypothesis to prove the suspicion above is a. h0 : μ1- μ2­ = 0; ha : μ1- μ2­ ≠ 0 b. h0 : μ1- μ2 ≥ 0; ha : μ1- μ2 < 0 c. h0 : μd ≥ 0; ha : μd < 0 with μd = μ2- μ1 d. h0 : μd = 0; ha : μd ≠ 0 with μd = μ2- μ1 e. h0 : μ1- μ2 = 0; ha : μ1- μ2 ≥ 0
