a.
To describe: The shape of the distribution.
The shape of the distribution is Bimodal.
Given:
The histogram shows the sugar content (as a percent of weight) of 49 brands of breakfast cereals:
Calculation:
There are two peaks in the given histogram, one peak centered at about 5 and another peak centered about 45.
Conclusion:
The shape of the distribution is Bimodal.
b.
To describe: The reason for the shape of the histogram.
The cereals can be classified as low as well as high sugar content.
Given:
The salaries of the workers in one department of the Garcia Brothers Company (given in thousands of dollars) are as follows:
Calculation:
From part
The two peaks originate from the fact that most cereals either have low sugar content(5%) or high sugar content(45%).
Thus, the cereals can be classified as low as well as high sugar content.
Conclusion:
The cereals can be classified as low as well as high sugar content.

- Let the region R be the area enclosed by the function f(x)= = 3x² and g(x) = 4x. If the region R is the base of a solid such that each cross section perpendicular to the x-axis is an isosceles right triangle with a leg in the region R, find the volume of the solid.
