Answer:
This isn't the best worded question but from what I understand a larger sample size decreases the margin of error. If he would like a more accurate answer a larger sample size of the viewers will give more accurate answers.
Step-by-step explanation:
m =( Y2 - Y1)/ (X2-X1)
m =( 3-(-5))/ (-6-3)
m = - 8/9
I am assuming you meant a slope of 9/8 in your original question, so the points perpendicular to I are answer D.
Perpendicular means the slope is opposite reciprocal of your first slope given.

Step-by-step explanation:
The given matrix equation is:
To find Matrix X, we need to multiply both sides of the equation by 2 to obtain:
This simplifies to;
By scalar multiplication, we multiply each entry in the matrix A by to 2 to obtain matrix X.
Set as a proportion
16 = 12
------------------
5x+2 24
cross multiply
12(5x+2) = 16 * 24
60x +24 = 384
60x +24-24 = 384-24
60x =360
60x/60=360/60
x =6
To figure AB plug 6 into 5x+2
5x +2
5(6) + 2
30+2
32
AB = 32
