Clive needs to write 20 paragraphs for a school assignment. He has already written 10 and can write 5 paragraphs per hour. Clive solves for the number of hours it will take to complete his assignment by subtracting 10 from 20 and then dividing by 5.
Which of the equations below can be solved using the same steps?
O A 10z +5 - 20
OB. 5z + 10 - 20
OC. 5z + 10% = 20
OD. 20z - 10% = 5

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
