Keith left his house, rode his bike 3 miles along one road, took a 90 degree turn, and rode 3 miles to the local swimming pool. if he had ridden directly to the pool, how much distance would he have saved? round the answer to the nearest tenth of a mile. mc016-1.jpg

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.)

Asap! i'm not good math and i'm lost.

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
