Answer:
76 on second exam, 80 on third exam
Step-by-step explanation:
First, find the total of all 3 test scores by multiplying the average by the number of elements. 81 · 3 = 243.
The first score is 83 so 243 - 83 = 160. 160 is the other two test scores combined.
To find the other 2 scores, divide 160 by 2, which is 80.
The second score is 4 less so it will be 76. The third score is 80.
Answer:
-2, 0, 0.4, 1.1, 2, 12, 53, 58
Step-by-step explanation:
The formula for the area of a square is A = s^2, where s is the side length. Here, 225 cm^2 = s^2.
To find the side length, we need only take the sqrt of both sides of this equation and eliminate the negative root:
plus or minus √{225 cm^2) = s. Thus, s = 15 cm = side length.
