Sort these correlation coefficients from the weakest correlation to the strongest: -09,0.56, 0.05, -0.4, 0.8

0.05, -0.4, 0.8, 0.56, -9

Step-by-step explanation:

In this case, negative signs don't matter, just the values themselves. Think of it like absolute value. Then you list them, from smallest value to greatest.

Hope this helps :)

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

the answer will be b x² +x-1
