Fill in the blank: when using the least squares method, the line of best fit is the line that

a- minimizes the total area of error squares on the scatter plot
b- minimizes the sum of the squared deviations of the data points from the line
c- both a and b
d- none of the above

take it another

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
