The populations is all of the beavers at the park and the sample is the 10 that he randomly chose. A population means the total amount, so it wouldn’t make sense that it would be 10. A sample is a portion of the entire population, so 10 would be the right answer since it is only a portion of the entire population. 31 does not work because it is the data that is found using the sample of 10 beavers.
Total = amount Amy has(A) + amount Ruben has(R) + amount Sam has(S)
S = 3 * R
R = A + 9
S = 3 * (A+9)
S = 3A + 27
71 = A + (A + 9) + (3A + 27)
71 = 5A + 36
5A = 35
A = $7
R = A + 9
R = 7 + 9
R = $16
S = 3 * R
S = 3 * 16
S = $48
Answer:
He would be able to play for 5 games
Step-by-step explanation:
9 divided by 1.75 to get 5.14
The answer is B, because if you take the sqrt(144) you get the answer which is 12
