The linear function f(x) = 0.5x + 80 represents the average test score in your math class, where x is the number of the test taken. the linear function g(x) represents the average test score in your science class, where x is the number of the test taken. x g(x) 1 81 2 83 3 85 part a: determine the test average for your math class after completing test 2. (2 points) part b: determine the test average for your science class after the completing test 2. (2 points) part c: which class had a higher average after completing test 4? show work to support your answer. (6 points)

If anyone has done the algebra 2 chaos theory portfolio would you be wiling to me? i kind of know what i'm doing i just don't know if i'm doing it right.

Abcd is a square. what is the measure of angle bac

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.
