The <u>correct answer</u> is:
0.872.
Explanation:
The correlation coefficient of a regression line is a measure of how closely the line fits our data. Negative correlation coefficients represent decreasing lines; positive correlation coefficients represent increasing lines.
The closer a correlation coefficient is to +1 or -1, the better the fit; a perfect positive fit is r=1 and a perfect negative fit is r=-1.
We can see in the graph that the line is very close to our data, so it is a pretty good fit.
The line is increasing; this means we want a correlation coefficient that is close to 1.
The best choice is 0.872.
5x +12 = 6x - 10
Move the 5x over to the right by subtraction
12 = x - 10
Then move the 10 to the left by addition
22 = x

26 Square Inches.
If you find the area of the two missing fragments, which are 3 in. by 4 in., you can make the equation 2(3 x 4)= 24. Find the area of the whole 5 in. by 10 in. which is equal to 50 in. Subtract 24 from 50 and you get 26.
