Question

Math

Answer 1

@Vocaloid do I just find the relative frequency then simplify?

Answer 2

it's asking for the ratio of (people who like to watch TV and a movie)/(people who don't like either)

so you would just look at the table for the two appropriate values and find the ratio

Answer 3

32:4 or 8:1?

Answer 4

hm. my guess is that they'd want the simplified version 8:1

Answer 5

good

Answer 6

i only need help because the fractions always mess me up

Answer 7

well it looks like it would intercept the y-axis at about (0,5) and it also crosses (20,20) on the nose

so you just need to find the slope between (20,20) and (0,5)

Answer 8

B is out because its +3

Answer 9

15/20 = 3/4

Answer 10

D

Answer 11

good

Answer 12

good

Answer 13

Meta-Calc^

Answer 14

yeah that's good

Answer 15

-17?

Answer 16

residual = actual - predicted

the regression equation gives you the predicted value (-17)

the actual value is the y-coordinate of the given point (3)

so residual = 3 - (-17)

Answer 17

-20?

Answer 18

careful with your signs

3 - (-17) = 3 + 17

Answer 19

20

Answer 20

good, that's it
