Answer:
B. 14.075
Step-by-step explanation:
The mean is calculated by adding up all of the data points and then dividing the sum by the amount of points added.
The mean fitness score was 3.2 points. If all of the students scored the same thing (3.2 points) then this would be the fitness score of each student.
Thus, the answer is D. 3.2 points.
96 = -6 * (-4 - 3y) <== It's easiest to solve when the y is on the right
↓
-6 * (-4 - 3y) = 96 <== Multiply the -6 by everything inside the
parentheses
<span>↓</span>
24 + 18y = 96 <== Subtract the 24 from both sides
↓
18y = 72 <== Divide both sides by 18
↓
y = 4
The correct answer is choice B. y = 4.
Hope that helped =)
