6. A scatter plot of the residuals NORMAL FLOAT AUTO REAL RADIAN MP from a linear regression are shown
at the right. The plots are (1,1.3),
(2.-2.2), (3,1.6), (4,-1.1), and
(5,0.4). Which statement is true
about the sum of the residuals?
Choose:
o The sum is positive.
o The sum equals zero.
o The sum is negative.
o The sum is unknown.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

it is 10.6 according to my calculations
