Two classes took the same math test. In one class, the high score was 98% and the low score was 75%. In the other class, the high score was 96% and the low score was 51%. Explain what each measure of measure of central tendency could tell you about these class scores and the comparison of how the two classes did on the test? Explain your reasoning.

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
