Find the mean temperature.
Find the new sum of temperatures. Then, use the new sum of temperatures and number of days to set up an expression to find the mean.
Day Temperature °F
Monday 64
Tuesday 60
Wednesday 54
Thursday 60
Friday 62
Saturday 84
Mean =
Mean temperature = (64 + 60 + 54 + 60 + 62 + 84) / 6
Mean temperature = 384 / 6
Mean temperature = 64°F
New sum of temperatures = 64 + 60 + 54 + 60 + 62 + 84
New sum of temperatures = 384
Expression to find the mean temperature:
Mean temperature = New sum of temperatures / Number of days
Mean temperature = 384 / 6
Mean temperature = 64°F
