C. above

The value of the least-squares regression line at x=8 is ___.

A. -6.4

B. 0

C. 12

D. 19.2

E. 25.6

So, the residual of the data point (8,19.2) is .

A. -19.2

D. 12

E. 19.2

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

b

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
