Question

В футбольной команде 4 игрокам по 19 лет 3 игрокам по 20 лет и 4 игрокам по 21 году. найдите средний возраст игроков команды.

Answer 1

((19*4)+(20*3)+(21*4)) : (4+3+4) =220 : 11 = 20 лет

Answer 2

19 * 4 = 76

20 * 3 = 60

21 * 4 = 84

76 + 60 + 84 = 220

4 + 3 + 4 = 11

220 : 11 = 20 лет - средний возраст команды

можно сразу написать выражение:

(19*4+20*3+21*4) : (4+3+4) = 220 : 11 = 20

Answer 3

Calculating the Average Age of the Football Team

To find the average age of the football team, we can use the following formula:

Average Age = (Sum of all individual ages) / (Total number of players)

Given that there are 4 players aged 19, 3 players aged 20, and 4 players aged 21, we can calculate the average age using the provided information.

Average Age = (4*19 + 3*20 + 4*21) / (4 + 3 + 4)

Average Age = (76 + 60 + 84) / 11

Average Age = 220 / 11

Average Age = 20

Therefore, the average age of the football team is 20 years.
