  • Q #1: A large pizza has a diameter of 12 inches. Which of the following is the area of the pizza in terms of pi ()?

    A. 24 πi n2

    B. 48 π in2

    C. 18π in2

    D. 36 π in2

    Answer Explanation

    Before finding the area of the pizza, we need to find the radius of the pizza.

    Find radius of the pizza in terms of diameter

    Next, find area of the pizza using the radius of 6 inches

    Substituting r=6 in the equation of the area of a circle

    Thus, the pizza has an area of 36 π in2.

  • Q #2: When the marks of a science test are graphed, the distribution of markss is symmetric with the majority of weights centered around a single peak. Which of the following describes the shape of this distribution?

    A. Uniform

    B. Skewed right

    C. Bell-shaped

    D. Bimodal

    Answer Explanation

    In a bell-shaped curve, the data distribution is symmetric around a single peak. The centering of data around a single peak means the mean, mode and median of the test are all equal to each other.

  • Q #3: Five friends are sharing a pizza. Two friend eats a quarter of the pizza. The other three friends equally divide the rest among themselves. What portion of the pizza did each of the other three friends receive?

  • Q #10: As a person climbing a mountain increases walking speed, the rate of calories burned, height traveled, and energy expended also increase. Which of the following is the independent variable?

    A. Walking speed

    B. Energy

    C. Calories

    D. Height
