If the mean weight of 3 outfielders on the baseball team is 194 lb and the mean weight of the 6 other players is 229 lb, what is the mean weight of the 9-person team?

217.33 Ib

Step-by-step explanation:

The mean of a set of numbers is the ratio of the total of these numbers to the number of numbers added. As such where there are x numbers and the sum of these numbers is T, the mean is

= T/x

If the mean weight of 3 outfielders on the baseball team is 194 lb, the total weight  of the 3 outfielders

= 194 * 3

= 582 Ib

the mean weight of the 6 other players is 229 lb, the total weight  of the 6 outfielders

= 229 * 6

= 1374 Ib

Total weight of the 9 players

=  1374 Ib + 582 Ib

= 1956 Ib

Mean of 9 person team

= 1956/9

= 217.33 Ib
