Question

in a high school league, there were 256 touchdowns made last year. if 64 games were played, what is the mean, or the average, number of touchdowns made per game?
4
192
320
16,384

Explanation:

Step1: Recall mean formula

The mean (average) $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $\sum_{i = 1}^{n}x_{i}$ is the total number of touchdowns and $n$ is the number of games. Here, $\sum_{i = 1}^{n}x_{i}=256$ and $n = 64$.

Step2: Calculate the mean

$\bar{x}=\frac{256}{64}=4$
