2.5.171 A medicine ball manufacturer developed process results in a ball that lasts roughly four times as long as a ball produced by the current process To showing a "new ball having four times the radius of the "old ball. Complete parts (a) and (b) below. has determined that a newly Old ballNew ball Type an exact answer, using radicals as needed.) O A. The area of the "new ball in the brochure gives the visual impression that it lasts onlytimes as long as the 'old" bell, which is les than four times as long OB. The graph is truncated and gives the impression that the "new ball lasts only times as long as the "old bal, which is less than four times as iong. O C. The area of the 'new ball in the brochure gives the visual impression that it lastsimes as long as the fold" bal, which is more than four times as long 5 5 3

Explanation / Answer

Answer 2.5.171
Option C is correct
The area of the new ball in the brochure gives the virtual impression that it lasts 10 times as long as old ball, which is more than four times as long
We assume it to be 10 times because we can fit 10 old balls in the one new ball, so we take it as 10 times as long as old ball

Answer 2.4.131
Option E, F and H are only possible symmetric distributions because the mean, mode and median in Option E and F are shown at the same point
Option A and B are not symmetric because these distributions are left skewed
Option D is bimodal distribution which is skewed
Option C and G are right skewed, that’s why these are not correct answer
