I'm not sure what to do for the "arithmetic approach" but for the algebraic approach:
The equation you need to solve would be 5.35x + 182.90 = 750
when you solve it, you would get x = 106, meaning they would have to sell 106 more
Very confident because a correlation coefficient of 1 is perfect then a correlation coefficient of .96 means it is like 96% accurate
The answer to the question
Answer:
to anyone who takes this its not mixed, I think it might be endpoint but I honestly don't know.
Step-by-step explanation:
took the quiz edge 2021
Multiply by 10
2x+50=190-5x
190=2x+50+5x
140=7x
x=20
