Question

Jack scored a mean of 15 points per game in his first 3 basketball games. In his 4th game, he scored 27 points. What is his mean score for the first 4 games?

Answer 1

His mean score for the first 4 games will be 18 points.

Explanation

In the first 3 games, the mean of the scores is 15 points . Mean is the simple average of some numbers.

So, the total score in first 3 games = $(15*3)= 45$ points

Now, in the 4th game, he scored 27 points. So, the total score in the first 4 games = $45+27= 72$ points

Thus, the average of scores in first 4 games = $\frac{72}{4} = 18$ points

So, his mean score for the first 4 games will be 18 points.
