John scored a mean of 19 points in his first.3 basketball games. In his fourth game, he scores 23 points. What is his average score for all four basketball games?

20

Step-by-step explanation:

We are told in the question that

John scored a mean of 19 points in his first 3 basketball games

His total points for his first 3 games = Number of games × Mean of those games

= 3 × 19

His total points for his first 3 games = 57 points

We aslo told that in his fourth game, he scores 23 points.

His average score for all four basketball games is calculated as:

(57 points + 23 points) ÷ 4 games

= 80 points ÷ 4 games

= 20

His Average for the four games = 20
