Suppose a straight line has been used to model the relationship between two quantitative variables represented on a scatter plot. Which of these statements are correct? Select all that apply.

Answer choices:
A. The farther away the points on the scatter plot are from the line, the better model fit.
B. The closer the points on the scatter plot are to the line, the worse the model fit.
C. The closer the points on the scatter plot are to the line, the better the model fit.
D. The farther away the points on the scatter plot are from the line, the worse the model fit.

step-by-step explanation:

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
