If you toss a pair of dice 1,000 times, how many times would you expect to get a sum of 12 as the result?
1.)about 12 times 2.)about 27 times 3.)about 36 times 4.)about 100 times the lesson doesn't show me how to work this. whats the formula?

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)
