If 21 is the final answer to the equation then x would be 9
Answer:
Step-by-step explanation:
To solve this problem one can use the trigonometric ratios, these ratios are the following,
In this problem, one is given the adjacent side, and is asked to find the opposite side, thus use the function (). Substitute in the given value and solve,
Inverse operations,
Solve,
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:
28/41
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
5/2= 2.5 ((or 2 1/2) (or 250%) any you prefer) But you can't get half a person to come in the amusement park so we round it down (2.5 → 2)
So the answer is 2
