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. For number of hours worked and free - time: As the number of hours worked increases, free time decreases, showing a negative correlation.
  2. For the speed of a train and the length of time to reach the destination: Faster speed means less time to reach the destination, indicating a negative correlation.
  3. For a tadpole's age and the length of its tail: As a tadpole ages, its tail length decreases, which is a negative correlation.
  4. For speed of a car and minimum stopping distance: Faster speed leads to a longer stopping distance, which is a positive correlation.
  5. For adult's head circumference and age: There is generally no significant linear correlation between adult head circumference and 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
