  • Q #1: The width of a rectangle is 4 inches (in) and the area of the rectangle is 32 in2. Which of the following is the length of the rectangle?

    A. 8 in

    B. 28 in

    C. 36 in

    D. 128 in

    Answer Explanation

    We need to find the length of the rectangle from the given area and width of the rectangle. Let L be length if the rectangle. Then,

    Area of rectangle=Length*width

    Substituting area=32 in2 and w=4 inches

    32=L*4

    32=4L

    Divide both sides by 4

    32/4=4L/4

    8=L

    The length of the rectangle is 8 inches.

  • Q #2: A teacher has asked all the students in the class which days of the week they get up after 8 a.m. Which of the following is the best way to display the frequency for each day of the week?

    A. Pie graph

    B. Bar graph

    C. Histogram

    D. Scatterplot

    Answer Explanation

    The best way to display the frequency of each day of the week when students get up after 8 a.m. is by using a bar graph. Bar graphs are well-suited for representing categorical data, where each day of the week is a separate category, and the height of each bar corresponds to the count or frequency of students waking up late on that specific day.

    Note: Histograms, on the other hand, are more appropriate for visualizing continuous or numerical data and are not ideal for categorical data like days of the week. Histograms are useful for understanding the distribution of data, identifying patterns, and assessing the shape of the data distribution, such as whether it's normally distributed, skewed, or has multiple modes.

    As you can see below, the Histogram is used to depict a pattern/continuous data. While a bar graph does just fine even with discrete data.

  • Q #3: To determine the insurance of a car, an insurance company considers the following determinants: the age of the car, the model of the car, and the mileage of the car. Which of the following is the dependent variable?

    A. Model

    B. Insurance premium

    C. Mileage

    D. Age

    Answer Explanation

    A dependent variable is one that when another variable changes, it also changes. In our case, the insurance premium changes if the age, model, mileage of car changes. Thus, insurance premium is the dependent variable while the other three are independent variable.
