The correlation coefficient for the data in the table is A. –0.993
<h3>Calculations and Parameters:</h3>
Using this formula: ![r = \frac{n(\sum xy)-(\sum x\sum y)}{\sqrt{n\sum x^2-(\sum x)^2}\sqrt{n\sum y^2-(\sum y)^2}}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7Bn%28%5Csum%20xy%29-%28%5Csum%20x%5Csum%20y%29%7D%7B%5Csqrt%7Bn%5Csum%20x%5E2-%28%5Csum%20x%29%5E2%7D%5Csqrt%7Bn%5Csum%20y%5E2-%28%5Csum%20y%29%5E2%7D%7D)
We would use x and y to represent the unknowns.
n = 4
We have,
- ∑x = 42,
- ∑y = 44.37 ,
- ∑xy = 461.3
- ∑x^2 = 446,
- ∑y^2 = 494
Putting these values in the formula
would bring the answer as. A. –0.993

No 2 numbers do this.
Possible numbers that can multiply to 108:
<span>1 x 108 = 108
2 x 54 = 108
3 x 36 = 108
4 x 27 = 108
6 x 18 = 108
9 x 12 = 108
12 x 9 = 108
18 x 6 = 108
27 x 4 = 108
36 x 3 = 108
54 x 2 = 108
108 x 1 = 108

By definition we have the meaning of FOIL is given by:
F: First
O: Outer
I: Inner
L: Last
We have then the following product:
![(x-3) (4x + 2) ](https://tex.z-dn.net/?f=%28x-3%29%20%284x%20%2B%202%29%0A)
Applying the FOIL method we have that the products are given by:
Answer:
the answer choice showing the FOIL method products is:
B. (X) (4x) + (2) (x) + (- 3) (4x) + (- 3) (2)
