Auto racing is a sport enjoyed by many people. In each race, there may be up to 25 cars on the racetrack. Which of the following is NOT an example of a quantitative variable you might use to describe a car in a race? A. the brand of car
B. the number of tires used
C. the number of laps completed
D. the average speed (in mpg)

A. the brand of car

Step-by-step explanation:

quantitative variable  are those variable whose value can be represented by any number. The number may be fractional, decimal or discrete. But it should have some value like 2, 8, 1000 , 3.555, 4/5 ETC.

Given

A. the brand of car

The brand cannot have numerical  value. Brand has value like ferrari, mercedes, SKODA , JEEP etc.

Hence,

A. the brand of car is an example of a quantitative variable that  might not  be used to describe a car in a race. (Answer)

Other three

can have numerical values

as

the number of tires can have value 1,2,3,4,5

the number of laps completed can have value from 0, 1, 2, ...to n laps as decided for thr race

average speed can have value 40 km.hr, 45.666 km/hr ...etc

no, because the sides are not congruent

both equations and proportions are better.
