It takes 12 minutes for Josephine to ride her bike 3 miles from home to school. At this rate, how long would it take Josephine to ride her bike from school to the neighborhood swimming pool if the distance is 10.5 miles?

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

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.
