Q. Carol, the band director, tracked how many minutes each saxophone player practiced last week. She found that Sven practiced for 3030 minutes, Li Mihn practiced for 4545 minutes, Wendy practiced for 9090 minutes, Thomas practiced for 7575 minutes, and Gabriel practiced for 6060 minutes.\newlineFind the mean length of practice time.\newlineminutes\text{minutes}
  1. 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.\newlineCalculation: Total practice time = Sven's + Li Mihn's + Wendy's + Thomas's + Gabriel's practice times.\newlineTotal practice time = 3030 minutes + 4545 minutes + 9090 minutes + 7575 minutes + 6060 minutes.\newlineTotal practice time = 300300 minutes.
  2. Find Mean Practice Time: Next, we need to divide the total practice time by the number of saxophone players to find the mean.\newlineThere are 55 saxophone players.\newlineMean practice time = Total practice time / Number of players.\newlineMean practice time = 300300 minutes / 55 players.\newlineMean practice time = 6060 minutes.
