A coin is being tossed from a 40 foot tall tower of a castle. The coin is tossed upward off of the
tower with a velocity of 9 ft/sec. Use the
formula h(t) = -16t2 + vt + s where h is the height
of the coin, t is the time, v is the starting
velocity and s is the starting height of the coin.
Which of the following would be the equation
that represents the given situation?

Arecent study focused on the number of times men and women who live alone buy take-out dinner in a month. assume that the distributions follow the normal probability distribution and the population standard deviations are equal. the information is summarized below. statistic men women sample mean 24.85 21.33 sample standard deviation 5.54 4.93 sample size 34 36 at the 0.01 significance level, is there a difference in the mean number of times men and women order take-out dinners in a month? state the decision rule for 0.01 significance level: h0: μmen= μwomen h1: μmen ≠ μwomen. (negative amounts should be indicated by a minus sign. round your answers to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? what is the p-value? (round your answer to 3 decimal places.)
