If the mean weight of 4 backfield members on the football team is 222 lb and the mean weight of the 7 other players is 198 lb, what is the mean weight of the 11 person team?

To find the Mean or Average you have to add up all numbers it is asking for which in case are 222 and 198.

so you will add 222+198

That will equal 420

Then you will divide with the amount added together which is 2

420/2=210

so the mean of the 11 people is 210 or 210lbs

were is the equation
