(If you're stumped, I figured it out ;) )

Answer 5

@yoyogators

Answer 6

Okay hold on

Answer 7

The x goes up 2 as the y goes down by 8

Answer 8

So it is a negative slope

Answer 9

Correct :)

Answer 10

So just keep subtracting 8 from that number until i reach 27?

Answer 11

Or is there an easier way to do it?

Answer 12

There is an easier way. I'm making a formula for you right now :)

Answer 13

y = 250 - 4x

Answer 14

Wait would it be 154?

Answer 15

Nope

Answer 16

Use the formula

Answer 17

Okay so x would be 27 correct?

Answer 18

Correct :)

Answer 19

So y = 250 - 4(27)

Answer 20

Exactly :D

Answer 21

y = number of sweaters sold

Answer 22

So 142?

Answer 23

Yep

Answer 24

Now for B :)

Answer 25

Negative right?

Answer 26

The correlation would be negative?

Answer 27

The correlation is negative :)

Answer 28

So what is a coefficient?

Answer 29

Would the "Correlation coefficient" still be negative?

Answer 30

4 in 4x is a coefficient. But I would have to look up correlation coefficient

Answer 31

So what should i put down? The correlation coefficient is negative?

Answer 32

Yep. The correlation coefficient is negative and strong. That's the answer to B

Answer 33

Part c would be causation right?

Answer 34

Because causation is something that is caused from something that wouldnt usually happen

Answer 35

Causation, because the discount would cause the number of sweaters sold to increase. So yes, you're right :)

Answer 36

Okay thank you very much Sir!
