First, let's consider triangles and parallelograms. Notice that if we cut a parallelogram diagonally to divide it in half, we form two triangles, with the same base and height as the parallelogram. (please answer quickly)

Part a : solve - vp + 40 < 65 for v . part b : solve 7w - 3r = 15 for r show your work!

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.

Which zero pair could be added to the function f(x) = x2 + 12x + 6 so that the function can be written in vertex form? o 3, -3o 6,629,-936, 36
