Question

The graph below plots the values of y for different values of x:

Answer 1

Which correlation coefficient best matches the data plotted on the graph?

0.5
0.8
0.9
1.0

Answer 2

1.0

Answer 3

Can you tell me how? I just want to make sure. ^-^

Answer 4

ok hold on

Answer 5

I'm working on it

Answer 6

Okay.

Answer 7

i said thaT BECAUSE they are spaced out by 1

Answer 8

I don't get it. O.o Also, why would it take 15 whole minutes for you to type that? O.o

Answer 9

@SolomonZelman Can you check this?

Answer 10

I can't determine which function it would be, but probably some positive cubic function. The spacing between the points seems to be 1.0 (1 unit exactly).

The points have different changes in y between them, but the change in x is same. it is the aforementioned "1".

Answer 11

I would also take 15 minutes to type it, (perhaps), because I haven't ever done these questions, when I studied this. (maybe because it is too simple, once you know what you are asked -> the change in x).

But I never did this type of problems in my algebra.

Answer 12

Okay. Thanks. :)

Answer 13

Anytime.
