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:

Step-by-step explanation:
Answer:Find out the expressions for the number of sweets sue and tony have now .
To proof
As given
Sue has 18 sweets. tony has 18 sweets.sue gives tony x sweets
thus
sue sweets = 18 - x
Tony sweets = 18 + x
As given
Sue then eats 5 sweets. Tony then eats half of his sweets
sue sweets becomes = 18 -5 -x
= 13 - x
Hence proved
