Answer:
13 is your answer
Step-by-step explanation:
Based on the regression line, and the data points, the sum of squared residuals is 22.
<h3>What is the sum of squared residuals?</h3>
The squared residual can be found as:
= (y - 3 + 2x)²
For point (4 , 8)
= (8 - 3 - 2(4))²
= 9
For point (2 , 5)
= (5 - 3 - 2(2))²
= 4
For point (1, 2)
= (2 - 3 - 2(1))²
= 9
The sum of squared residuals is:
= 9 + 4 + 9
= 22
Full question is:
The regression line = 3 + 2x has been fitted to the data points (4,8), (2,5), and (1,2). The residual sum of squares will be:

Answer:
17. xy + z = 51
18 yz - x = 18
21. 5z + ( y - x ) = 20
22. 5x - ( y2 - 4x ) = -10
23 . x2 + y2 - 10z = 70
24. z3 + ( y2 - 4x ) = 1
25. y + xz / 2
26 .3y + x2 / z = 30
Step-by-step explanation:
17.(6 x 8)+3=
48+3=51
18.(8 x 3)- 6 =
24 - 6 = 18
21. 15 + ( 8 - 3 )
15 + 5=
20
22 .30 - (64 - 24)=
30 - 40=
-10
23. 36 + 64 - 30
100 - 30
70
24. 9 + (16 - 24 )=
9 + -8 =
