The answer would be 8. hope this helps
F(x) = -9 + 10.3x probably.
It's definitely not the first or last option as they have negative gradients (i.e. negative x-coefficient) and so represent a negative correlation. The data given tells us there is a positive gradient and so a positive correlation.
It could be the second option as the second and third are not so vastly different but I would go for the third because it appears to most closely fit the data pattern.
Answer:
80%
Step-by-step explanation:
Please consider the complete question:
Micah is preparing for a piano recital. He practices for 50 minutes on Monday and 90 minutes on Wednesday. By how much did she increase the time she practiced each day?
We will use percent change formula to solve our given problem.

Upon substituting our given values, we will get:



Therefore, Micah had increased the time by 80%.
