Which is the best estimate of the correlation coefficient for the scatter plot?

a.1
b.-0.9
c.0.9
d.0.3

The best estimate of the correlation coefficient is 0.9 from the given data.

Step-by-step explanation:

From the scatter plot, the line of best fit will have a positive slope.

So, the correlation coefficient , is greater than 0.

so, ≠ - 0.9

Also, there is a deviation from absolute linearity.

So, ≠ 1

Again from the scatter plot it is closer to linearity than further.

Hence, ≠ 0.3 .

So = 0.9

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
