This should be easy but if I stay on this page to long it will long me out and lock the question :/

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

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.)

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers
