Answer:
B. 9.6 = the number of points you would increase each hour of studying;
65.8 = your score if you studied 0 hours
Step-by-step explanation:
A linear regression equation y = 9.6x + 65.8, with x representing hours.
When x = 0, then y = 65.8. This means
65.8 = your score if you studied 0 hours
When x = 1, then

is your score after studying one hour.
The score increased by
so
9.6 = the number of points you would increase each hour of studying.
Yes. The opposite rays mean they are in the same line.
Plug in the dimensions to the formula given using a handy dandy calculator for both problems.
1. The diameter of the bottom of the cone is 4 so the radius (half that) is 2. Volume = 1/3 * pi * (2)² * 6
= 1/3 * pi * 4 * 6
= 1/3 * pi * 24
= 8 * pi
≈ 25.1327 cm³
2. They give you all you need, the radius.
Volume = 4/3 * pi * (6)³
= 4/3 * pi * 216
= 288 * pi
≈ 904.7787 in³
This would be a binomial model, since there is a fixed number of trials, the probabilities are independent and there are only two choices (either the shot is made or missed).
