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

Answer

Brief Explanations:

  1. As the number of hours worked increases, free - time decreases, showing a negative correlation.
  2. As the speed of a train increases, the time to reach the destination decreases, indicating a negative correlation.
  3. As a tadpole ages, its tail length decreases, which is a negative correlation. The speed of a car and minimum stopping distance have a positive correlation (faster speed means longer stopping distance). Adult head circumference and age generally do not have a clear negative correlation as adult head circumference is relatively stable with age.

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 it’s tail
