8 0

Answer:

15, 8, 13, 13

Step-by-step explanation:

(1) mean =  Σx / n = 135 / 9 = 15

(2) range = highest value - lowest value = 21 - 13 = 8

(3) mode = 13 (most repeated value in data set)

(4) for 9 values in a data set, we have that (9 + 1) / 2 = 5th number

median = 13

The number of goals scored by a soccer team varies directly as the number of shots on goal. If the Lakeside Bears scored 4 goals
enot [183]

Since it varies directly, divide the number of shots by the number of goals:

48 shots / 4 goals = 12

This tells you they score a goal every 12 shots.

Multiply shots needed by number of goals:

12 x 3 = 36

They need 36 more shots to score 3 more goals.
