The measures the variation in the dependent variable that is explained by variables other than the independent variable in simple regression analysis . a. total sum of squares
b. sum of squares error
c. sum of squares within
d. sum of squares regression

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

a is the right answer
