HELP ASAP! PLEASE! 50 POINTS! Since 1970, the number (in thousands) of males M and females F attending institutes of higher education can be modeled by:
M = 0.09t^3 - 4.8t^2 + 110t + 5000 and F = 0.19t^3 - 12t^2 + 350t + 3600
where t is the number of years since 1970. Write a model for the total number of people attending institutes of higher education.

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.)
