Which scatterplot shows no correlation?

A. A graph with both axes unnumbered. A scattered line increases from left to right.

B. A graph with both axes unnumbered. A scattered line decreases from left to right.

C. A graph with both axes unnumbered. A short scattered line increases from left to right.

D. A graph with both axes unnumbered. A line zig zags up and down the graph.

D. A graph with both axes unnumbered. A line zig zags up and down the graph.

Step-by-step explanation:

Any form of scattered line shows correlation. A line shows that as on variable increases the other decreases. A line that has no obvious direction, like one scattered, shows no correlation. Look at the image for a better visual of what I mean.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
