Solution By Steps

Step 1: number of hours worked and free time

If someone works more hours, they likely have less free time. This suggests a negative correlation.

Step 2: speed of a car and minimum stopping distance

As the speed of a car increases, the minimum stopping distance typically increases, indicating a negative correlation.

Step 3: a tadpole’s age and the length of its tail

Typically, as a tadpole ages, the length of its tail decreases, implying a negative correlation.

Final Answer

The relationships that could have a negative correlation are:

number of hours worked and free time

speed of a car and minimum stopping distance

a tadpole’s age and the length of its tail.

Summary

Understanding negative correlation is crucial in various fields like economics, biology, and transportation. Recognizing these relationships helps predict how changes in one variable may affect another in an opposite direction. This knowledge aids in decision-making processes and scientific analyses.
