A car dealer recently sold five cars for the following profits: $10,126, $9,999, $12,398, $12,007, and $4,567. What was the mean
yawa3891 [41]
The mean is the average
to find the average, first you add all the numbers together
10,126 + 9 999 + 12,398 + 12,007 + 4,567= 49,097
since you added five numbers together, you will divide by five
49,097 ÷ 5 = 9,189.40, so the answer is B
