Mr. jenning's physics class built different-shaped parachutes to see which shapes were more effective. the students tested the parachutes by dropping them from a height of 25 feet and timing the fall. they calculated the summary below:
mean std dev min q1 median q3 max
4.2 secs 0.5 sec 2.6 secs 3.4 secs 4.0 secs 5.7 secs 6.8 secs
the students want to see what happens to their times when they drop the parachutes from 35 feet. they find that every drop is increased by 1.5 seconds. find the new mean and standard deviation.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

Gexpressions: practice question 3 of 5 jackson wants to study the popularity of his music video by tracking the number of views the video gets on his website. the expression below represents the total number of views that jackson's video receives n days after he begins tracking the nu views, where b is the rate at which the number of views changes. alb)" select the statement that would accurately describe the effect of tripling a, the initial number of views before jackson beginst the rate at which the number of views changes, b, will triple. the total number of views the video has after n days, a(b)", will not change. the total number of days since jackson begins tracking views, n, will be reduced by one-third. the total number of views the video has after n days, alb)", will triple. submit
