A doctor is studying heights of newborn babies. The doctor uses 20 inches as a reference point. Babies in the study receive a score to show how close they are to 20 inches. A baby that is 21 inches long receives a score of +1. A baby that is 16 inches long receives a score of -4. NOTE: For your answer to be counted correctly, first enter + or - and then the number.

To determine the scores based on how far each height is from the reference point of 20 inches:

  1. A baby that is 21 inches long:
    Score = \(21 - 20 = +1\)
    So the score is +1.

  2. A baby that is 16 inches long:
    Score = \(16 - 20 = -4\)
    So the score is -4.

Therefore, the scores are:

  1. For the baby that is 21 inches long: +1
  2. For the baby that is 16 inches long: -4

To determine the score for a baby that is 18 inches long, you can calculate the difference from the reference point of 20 inches:

Score = \(18 - 20 = -2\)

So, a baby that is 18 inches long receives a score of -2.
