HURRY I HAVE NO LONG TIME . plz help
Find an equation for the line below.

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.)

How many solutions does the nonlinear system of equations graphed bellow have?

Given sin28.4=.4756, cos28.4=.8796, and tan28.4=.5407 find the cos of 61.6
