PLEASE HELP 25 POINTS When it is best to solve a system using analytical methods versus using graphical or algebraic methods?

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.)

What is the effect on the graph of the function f(x)=x when f(x) is replaced with -f(x)+4
