Question

If the mean weight of 4 backfield members on the football team is 230 lb and the mean weight of the 7 other players is 199 ​lb, what is the mean weight of the 11​-person​ team?

Answer 1

About 210lbs
Multiply the 230 by 4 to get 920
(230 average times 4 players)

Multiply 199 by 7 to get 1393
(199 average by 7 players)

Add the 920 and 1393 to get 2313
(Total weight of all players)

Divide the 2313 by 11
(Finding average)

210.27 is the answer
