Your shady uncle has given you a six-sided die that he claims is weighted so that the six is 3 times as likely as any other number. you wish to test his claim using a goodness-of-fit test at the α=0.005 significance level. so, you roll the die 110 times. what is your null hypothesis?

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)
