How does the mean absolute deviation (mad) of the data in set 2 compare to the mean absolute deviation of the data in set 1?

set 1: 16, 15, 10, 12
set 2: 16, 62, 15, 10, 12
a. the mad of set 2 is 10 less than the mad of set 1.
b. the mad of set 2 is 13.35 more than the mad of set 1.
c. the mad of set 2 is 10 more than the mad of set 1.
d. the mad of set 2 is 13.35 less than the mad of set 1.

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 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)
