Answer:
<h3>
The option B) is correct.</h3><h3>
That is the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible is correct answer</h3>
Step-by-step explanation:
Given that " The least-squares regression line "
The least-squares regression line is <u>the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible.</u>
Therefore option B) is correct
Answer:
x^2 +13x+22 =0
Step-by-step explanation:
Subtract the zero from x
(x- -11) (x- -2) =0
(x+11) (x+2) = 0
Foil
x^2 +2x+11x+22 =0
Combine like terms
x^2 +13x+22 =0
