REVIEW MODULE 1: DERIVING CONCLUSIONS
BASED ON NOTATION QUIzZ
Step 1 of 1
Question 1 of 14
The distance in miles that a car drives can be represented by the function D(g) = 28g,
where gis the number of gallons of gasoline.
If you drive 224 miles, how much gas do you use?
252 gallons
8 gallons
6,272 gallons
28 gallons
Correct! Substituting 224 for the function value, you get 224 miles = 28g. Using
inverse operations to solve for g, 224/28 = 8 gallons.
Question 2 of 14
, You want to drain your rectangular in-ground swimming pool, which contains 9,000
gallons of water. The amount of water remaining in the pool can be represented by the
function W (t) = 9—2t, where tis the time, in hours, after the draining began. The
function, W(1), is measured in thousands of gallons.
How many gallons of water are in the pool two hours after the draining procedure
begins?
7,000 gallons
5 gallons
5,000 gallons
4,000 gallons
Incorrect. Four thousand gallons is the amount that has been drained after two
hours.
Question 3 of 14
What describes a quantitative variable?
Dog breeds
Populations of cities in the United States
States in the United States
Primary colors (red, blue, and yellow)
Correct! A quantitative variable is a numerical value. Population is a number and
can be measured.
