I think the correct answer is 5.6569
Answer:
y = 2
x = 7
Explanation:
<u>Make the coefficient of "y" in equation 1 same</u>
{ 5x + 3y = 41 } * 2 → 10x + 6y = 82 ........equation 1
→ 3x - 6y = 9 ........equation 2
<u>solving them using linear combination</u>
============
Find y:
I agree. All real numbers except -1.
We need the coefficient of determination definition
The coefficient of determination (R²) is a number between 0 and 1 that measures how well a statistical model predicts an outcome. You can interpret the R² as the proportion of variation in the dependent variable that is predicted by the statistical model
So if we have a coefficient of determination of 0.233 we multiply by 100 to get the percentage
Answer: 23.3%
