1. a hot-air balloon flew at 10 miles per hour. using the variable h, write and solve a multiplication equation to find how many hours the balloon traveled if it covered a distance of 70 miles.
2. a passenger helicopter can travel 300 miles in the same time it takes a hot-air balloon to travel 20 miles. using the variable s, write and solve a multiplication equation to find how many times faster the helicopter can travel than the hot air balloon.
can you answer the two questions? ? : /

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.)
