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

minutes

Add practice times: 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. There are $5$ players: Sven, Li Minn, Wendy, Thomas, and Gabriel.
Calculate total: First, we add up the practice times: Sven's $30$ minutes, Li Minn's $45$ minutes, Wendy's $90$ minutes, Thomas's $75$ minutes, and Gabriel's $60$ minutes. The total practice time is $30 + 45 + 90 + 75 + 60$ .
Divide by players: Calculating the total practice time: $30 + 45 + 90 + 75 + 60 = 300$ minutes.
Calculate mean: Now, we divide the total practice time by the number of players to find the mean. There are $5$ players, so we divide $300$ minutes by $5$ .
Final result: Calculating the mean practice time: $300$ minutes $\div$ $5$ players = $60$ minutes.
Final result: Calculating the mean practice time: $300$ minutes $\div$ $5$ players = $60$ minutes. The mean length of practice time for the saxophone players is $60$ minutes.
