The width and the length of a rectangular piece of plywood are 4 feet and 8 feet, respectively. Along one edge of the plywood, a strip $$x$$ inches wide and 8 feet long is removed. Then, along an edge perpendicular to the 8-foot edge, a strip $$x$$ inches wide is removed. For what value of $$x$$ will the remaining rectangular piece have width and length in the ratio of 2 to 5? (1 foot = 12 inches)
Four toys—a stuffed animal, a ball, a toy car, and a doll—are to be distributed among three children—Jasmine, Katey, and Leah. If the toys are to be distributed in such a way that each child receives at least one toy, how many such distributions are possible?
Faucets $$X$$ and $$y$$ dispense water at their respective constant rates. Dispensing simultaneously, faucets $$X$$ and $$Y$$ fill an empty tub in 3 minutes. Faucet $$X$$, dispensing alone, takes $$\frac{3}{4}$$ as long as faucet $$y$$, dispensing alone, to fill the empty tub. Let $$x$$ and $$y$$ be the respective times, in minutes, that it takes faucets $$X$$ and $$y$$, each dispensing alone, to fill the empty tub. What are the values of $$x$$ and $$y$$?
A furniture store purchased sofas for a wholesale price of $400 each and sold most of them for a retail price of $560 each. In a summer sale, the retail price of the last few sofas was reduced by $$x$$ dollars, and they were sold at this reduced price.

For each value $$x$$ in a list of values with mean $$m$$, the squared deviation of $$x$$ from the mean is defined as $$(x-m)^2$$. The variance of the values in the list is the mean of the squared deviations.

For two lists of values. T and U, the numbers of values are equal and the means of the values are equal, but the variances of the values are distinct. List W consists of the values in T and the values in U combined.

Quantity A

The sum of the variances values in T and U

Quantity B

The variance of the values in W


The list price of a certain book is $$k$$ dollars. After the list price of the book is discounted by $$p$$ percent, the resulting price is $$n$$ dollars.
