Consider the following function.

f(x) = x^2/7, a = 1, n = 3, 0.8 ≤ x ≤ 1.2

(a) approximate f by a taylor polynomial with degree n at the number a. t3(x) =
(b) use taylor's inequality to estimate the accuracy of the approximation f(x) ≈ tn(x) when x lies in the given interval.

(round your answer to eight decimal places.) |r3(x)| ≤

Angles r and s are complementary. the measure of angle r is 31 degrees. which equation can be used to find angle s?

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.
