The scores of two school volleyball teams are recorded.

Team A scored the following points per game: 20, 17, 25, 25, 13, 25, 12, 25, 25
and 23.
Team B scored the following points per game: 25, 25, 9, 10, 25, 11, 25, 15, 10
and 25.
What is the mean of Team A?
What is the mean of Team B?

Answer 1

Time A:

Para obter a média temos que somar todos os pontos e dividir pela quantidade de pontos, ou seja, 20 + 17+ 25+ 25+ 13+

25+ 12+ 25+25 +23= 210/10= 21

A média do time A é 21 pontos.

Time B:

O mesmo procedimento,

25+ 25+ 9+ 10+ 25+

11+25+ 15+10 + 25= 180/10= 18

A média do time B é 18 pontos.
