A model rocket is launched into the sky. The quadratic function y =-16x2 + 32x models the height in feet of
the rocket after x seconds. How long is the rocket in
the air?

Which inequality comparing two of the expressions is true when 0.7 < x < 0.9

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.)
