Question

which relationships could have a negative correlation? select three options. number of hours worked and free time speed of a car and minimum stopping distance the speed of a train and the length of time to reach the destination adults head circumference and age a tadpoles age and the length of its tail

Explanation:

Step1: Analyze hours - worked and free - time

As the number of hours worked increases, free time decreases. So, it has a negative correlation.

Step2: Analyze car speed and stopping - distance

As the speed of a car increases, the minimum stopping distance increases. It has a positive correlation.

Step3: Analyze train speed and time - to - destination

As the speed of a train increases, the length of time to reach the destination decreases. It has a negative correlation.

Step4: Analyze adult head - circumference and age

Adult head - circumference does not change significantly with age. There is little to no correlation.

Step5: Analyze tadpole age and tail - length

As a tadpole ages, its tail length decreases. It has a negative correlation.

Answer:

number of hours worked and free time, the speed of a train and the length of time to reach the destination, a tadpole's age and the length of its tail
