Answer:
Equation :
Gallons needed = gallons
Step-by-step explanation:
It is given that:
Gallons of paint used by Tyler =
Area of fence painted = 5/7
Let,
x be the whole fence needed to paint.
Because we know that 5/7 of the fence is painted with 5/4 gallons of paint.
Multiplying the equation with 7/5
Therefore,
Equation :
Gallons needed = gallons
Answer-
The exponential model best fits the data set.
Solution-
x = input variable = number of practice throws
y = output variable = number of free throws
Using Excel, Linear, Quadratic and Exponential regression model were generated.
The best fit equation and co-efficient of determination R² are as follows,
Linear Regression
Quadratic Regression
Exponential Regression
The value of co-efficient of determination R² ranges from 0 to 1, the more closer its value to 1 the better the regression model is.
Now,
Therefore, the Exponential Regression model must be followed.
