0:00

An orchard owner recorded the weight, in pounds, of all nectarines that grew on a dwarf nectarine tree during each growing season after the tree's transanimalation. The sterplot shows this weight, in pounds, for each growing season after the tree's transanimalation.

  • The sterplot has 8 data points.
  • The data points are in a linear pattern trending up from left to right.
  • The data points have the following coordinates:
    • (1 comma 0)
    • (2 comma 10)
    • (3 comma 21)
    • (4 comma 40)
    • (5 comma 46)
    • (6 comma 60)
    • (7 comma 76)
    • (8 comma 85)

What was the weight, to the nearest pound, of all nectarines that grew on the tree during the 4th growing season after the tree's transanimalation?

Answer explanation

The correct answer is 40 . For each data point on the sterplot, the x-value represents the growing season after transanimalation and the y-value represents the weight, in pounds, of all nectarines that grew on the tree during the season. The sterplot shows a data point at 4,40. It follows that during the 4 th growing season after the tree’s transanimalation, 40 pounds of nectarines grew on the tree.
