Question 3 • FL-1200700-Mathematics for College Algebra MIS

Which relationships could have a negative correlation? Select three options.number of hours worked and free timespeed of a car and minimum stopping distancethe speed of a train and the length of time to reach the destinationadult’s head circumference and agea tadpole’s age and the length of it’s tail

Answer
A
number of hours worked and free time
B
speed of a car and minimum stopping distance
C
the speed of a train and the length of time to reach the destination
D
adult’s head circumference and age
E
a tadpole’s age and the length of it’s tail

Explanation

A negative correlation means that as one quantity increases, the other tends to decrease. More hours worked generally means less free time, and a faster train generally takes less time to reach the destination. As a tadpole gets older, its tail typically becomes shorter during development. The car’s stopping distance usually increases with speed, so that relationship is positive, not negative.
