Answer:

The correct option is C.

Step-by-step explanation:

The given data table is

  x          y

  2         15

  6         13

  7          9

  8         8

  12        5

Using calculator we get

Mean of x =7

Mean of y =10

SS_x=52

SS_y=64

r=-0.9534\approx -0.953

The correlation coefficient of the data set is -0.953.

Therefore the correct option is C.

Simplify, using the distributive<br> property.<br> 5f + 16f = (5 +?)f=?f
Soloha48 [4]

Applying the distributive property, we would simplify the expression as: 5f + 16f = (5 + 16)f = 21f.

<h3>How to Apply the Distributive Property?</h3>

The distributive property states that, ab + ac = (b + c)a.

Using the distributive property, we have:

5f + 16f

= (5 + 16)f

= 21f

Therefore, 5f + 16f is simplified as 21f.
