In one week, 8 dogs were brought to the city animal shelter. The vet's assistant recorded the weights, in pounds, of the dogs. Find the mean
Find the sum of the absolute deviations from the mean
Find the mean absolute deviation (MAD). Explain how you found the MAD​

Simply 8x squared + 5(7x squared- x) - 2x =

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)

The function models the number of accidents
