The first term of a sequence is 8. Each term after the first is 6 times the preceding term. If w represents the nth term of a sequence, which equation gives W in terms of n?
w = 6(8")
w = 6(81-1)
w = 8 (6")
w = 8(6-1)

Find the missing factor. 7s2 + 25s + 12 = (s + 3)( ).

Come up with a new linear function that has a slope that falls in the range 10 m − < < . choose two different initial values. for this new linear function, what happens to the function’s values after many iterations? are the function’s values getting close to a particular number in each case?

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.
