  • Q #1: Which of the following values is the greatest?

    A. 7/3

    B. 5.2

    C. 13/3

    D. 5.15

    Answer Explanation

    The initial step is to convert the decimal numbers into fractions.

    5.2 becomes 52/10

    5.15 becomes 515/100

    Next, find the least common denominator of 3, 10, and 100, which is 300. We use this value and multiply each fraction.

    7/3*300=700

    52/10*300=1560

    13/3*300=1300

    515/100*300=1545

    From the above, 1560 is the greatest value which corresponds to 52/10. Thus, 5.2 is the greatest value of all the choices given.

  • Q #2: Which of the following relationships represents a negative correlation between two variables?

    A. As a student’s class attendance decreases, the student’s overall grade remains the same

    B. As the number of hours a person exercises decreases, the weight of that person remains unchanged

    C. As the number of miles driven increases, the amount of the gasoline in the tank decreases

    D. As the amount of water plant receives increases, the growth rate of the plant increase.

    Answer Explanation

    Correlation of two variables falls into:

    Positive correlation: an increase in one variable causes another variable to increase

    Negative correlation: an increase in one variable causes another one to decrease

    No correlation: a change in one variable does not cause any response in another variable.

    From the given choices

    Option a is no correlation

    Option b is a no correlation

    Option c is a negative correlation

    Option d is a positive correlation

  • Q #3: 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

    Answer Explanation

    An independent variable is a change that when modified brings a change in other variables. In this case, the person increases his climbing rate, calories burned, distance traveled and energy used increases. Therefore, the walking speed is the independent variable while other variables are dependent.
