Q. Carol, the band director, tracked how many minutes each saxophone player practiced last week. She found that Sven practiced for

30

minutes, Li Mihn practiced for

45

minutes, Wendy practiced for

90

minutes, Thomas practiced for

75

minutes, and Gabriel practiced for

60

minutes.

\newline

Find the mean length of practice time.

\newline

\square

\text{minutes}

Calculate Total Practice Time: To find the mean length of practice time, we need to add up all the individual practice times and then divide by the number of saxophone players. $\newline$ Calculation: Total practice time = Sven's + Li Mihn's + Wendy's + Thomas's + Gabriel's practice times. $\newline$ Total practice time = $30$ minutes + $45$ minutes + $90$ minutes + $75$ minutes + $60$ minutes. $\newline$ Total practice time = $300$ minutes.
Find Mean Practice Time: Next, we need to divide the total practice time by the number of saxophone players to find the mean. $\newline$ There are $5$ saxophone players. $\newline$ Mean practice time = Total practice time / Number of players. $\newline$ Mean practice time = $300$ minutes / $5$ players. $\newline$ Mean practice time = $60$ minutes.
