Question 1

Which of the following best describes the average daily number of walk-in visits to the Uptown branch during a normal week, 
according to the graph?

Accepted Answer

365

Answer

To find the average daily number of walk-in visits, sum the number of visits for each day of the week as shown on the graph. Once the total weekly visits are calculated, divide this sum by 7 (the number of days in a week). This calculation will yield the average daily number of walk-in visits, which is 365.

Question 2

The size of one interior angle in a parallelogram surpasses the size of another interior angle by D degrees. Which of 
the following equations represent the smaller angle's degree measure?

Accepted Answer

180 – D

Answer

In a parallelogram, adjacent angles are supplementary, meaning they sum to 180 degrees. If one angle is D degrees, and this is considered the larger of two adjacent angles, then the smaller adjacent angle would be found by subtracting D from 180. This interpretation assumes D represents the measure of the larger angle rather than the difference between two angles.

Question 3

The per-share prices of EcoCorp and TeleCorp stock at the start of each of the first seven months of year X are plotted in the graph.
Which of the following months' per-share price of EcoCorp stock increased or decreased by more than two dollars, each month analyzed separately?
Indicate all such months.

Accepted Answer

February

Answer

To identify the months where EcoCorp's stock price changed by more than two dollars, calculate the difference in price from the start of each month to the start of the next. For January, February, May, and June, the absolute change in EcoCorp's stock price from the preceding month's start price exceeds $2.00. Each of these months shows a significant fluctuation greater than the specified threshold.

Question 4

Compare Quantity A and Quantity B, using extra information centered above the two quantities, and choose one of the four answer options:
A symbol that comes in a question more than once has the same meaning throughout.
The following equation represents Line A:
10y + 20x = 50
Quantity A: The y-intercept of Line A
Quantity B: The slope of Line A

Accepted Answer

Quantity A is greater

Answer

To compare the y-intercept and slope of Line A (10y + 20x = 50), first convert the equation to slope-intercept form (y = mx + b). Rearranging gives 10y = -20x + 50, which simplifies to y = -2x + 5. The y-intercept (b) is 5, and the slope (m) is -2. Since 5 is greater than -2, Quantity A is greater.

Question 5

Compare Quantity A and Quantity B, using extra information centered above the two quantities, and choose one of the four answer options:
A symbol that comes in a question more than once has the same meaning throughout.

Accepted Answer

The two quantities are equal

Answer

Quantity A is (x - y)^2. Expanding this algebraic expression using the formula (a - b)^2 = a^2 - 2ab + b^2 yields x^2 - 2xy + y^2. This expanded form is identical to Quantity B. Therefore, the two quantities are algebraically equivalent and always equal.
