What was the mean number of push-ups Erik performed?

\newline

____push-ups

Identify Total Push-ups: Identify the total number of push-ups Erik performed across all sets. $\newline$ To find the mean number of push-ups, we first need to add up the total number of push-ups Erik did in all the sets. $\newline$ $8$ (first set) + $5$ (second set) + $6$ (third set) + $9$ (fourth set) + $7$ (fifth set) + $8$ (sixth set) = $43$ push-ups.
Count Sets Completed: Count the number of sets Erik completed. Erik completed a total of $6$ sets.
Calculate Mean Push-ups per Set: Calculate the mean number of push-ups per set. $\newline$ To find the mean, we divide the total number of push-ups by the number of sets. $\newline$ Mean = Total push-ups / Number of sets = $43$ push-ups / $6$ sets.
Perform Division to Find Mean: Perform the division to find the mean. $\newline$ Mean = $\frac{43 \text{ push-ups}}{6 \text{ sets}} \approx 7.17 \text{ push-ups per set}.$ $\newline$ Since we cannot do a fraction of a push-up, we can round this to the nearest whole number if necessary, but for the mean, we can report the exact decimal.
