a) 48

b) 55

c) 60

d) 72

Answer 1

To achieve a mean score of 55 across their last four games, the OMS Lady Hawks basketball team must score 61 points in their final game, as their current total after three games is 159 points.

Step-by-step explanation:

The OMS Lady Hawks basketball team needs to determine what score they need in their final game to achieve their goal of a mean score of 55 for the last four games. The scores in the first three games were 42, 50, and 67 points. To find the required score for the fourth game, we will calculate the mean of all four games.

First, we add up the scores of the three games: 42 + 50 + 67 = 159. Since they want an average score of 55 points over four games, the total points for all four games should be 55 x 4 = 220 points. To find the needed score for the final game, subtract the sum of the first three games from the desired total: 220 - 159 = 61 points.

Therefore, the Lady Hawks must score 61 points in the final game to reach their target mean score of 55.
