The statistic that the coach should study is mean or the
average score of the two teams. If the coach wants to know if football players
who warm up before a game will score more points than those who don't warm up.
He will break the team up into two groups and make sure each player gets equal
time on the field. He will then count how many points each player makes during
the game. After counting them, add the scores of the group that he divided and
then divided it by the number of player in that group to get an average score
on teams that warm up or do not warm up before the game.
Answer:
(2,1)
Step-by-step explanation:
x=4×1/2=2
y=2×1/2=1
2m + 4s = 66.
4m + 3s = 84.
(Double the 2 glass of milk and 4 snack bars)
4m + 8s = 132.
4m + 3s = 84.
(Take away the second equation from the first equation)
5s= 48.
s = 48/5.
s = 9.6.
4m + 3(9.6) = 84.
4m + 28.8 = 84.
4m = 84 - 28.8.
4m = 55.2.
4m/4 = 55.2/4.
m = 13.8.
In a glass of milk, there are 13.8 carbs, and in a snack bar, there are 9.6 carbs.
2(13.8) + 4(9.6) = 66.
