a.

Explanation of Solution
Given information: The percent m of American males between the age of 18 and 24
who are no more than x inches tall is modeled by:
And the percent m of American females between the age of 18 and 24who are no more
than x inches tall is modeled by:
Calculation:
Given function are
The graph of the given functions using graphing calculator is shown below.
b.
To find: the horizontal asymptotes of the function using the graph of part (a) and interpret their meanings in the context of the problem.
b.

Answer to Problem 132E
The horizontal asymptotes are:
Explanation of Solution
Calculation:
The horizontal asymptote of the function is given by substituting the value of x −axis component to
The horizontal asymptotes are:
c.
To find: the average height for each sex( male or female).
c.

Answer to Problem 132E
Average height of male is 69.71.
Average height of male is 64.51.
Explanation of Solution
Calculation:
From the graph, most males and females are bigger than 52in tall and less than 78in tall and there are no more Americans male and female more than 78 in tall.
Average height of male is 69.71.
Average height of male is 64.51.
