PLEASE URGENT!

suppose company C produces packages of hazelnuts that are normally distributed with a mean of 93.5 individual hazelnuts and a standard deviation of 2.4 hazelnuts.
Company D produces packages of hazelnuts that are normally distributed with a mean of 95.9 individual hazelnuts and a standard deviation of 2.9 hazelnuts.

prove mathematically and explain which company is most likely to have a package with 91 hazelnuts.

please show work!

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)
