Answer:
C
Step-by-step explanation:
-1 cus its -1 becus u -1 so u get -1
Answer:
x = 5
y = 3
Step-by-step explanation:
9x and 45 are alternate interior angles, meaning they're congruent, so set them equal to one another, like so:
9x = 45
<em><u>Divide both sides by 9:</u></em>
x = 5
<u>Solving for y</u>, the two sides are of equal length, so set them equal:
6y = 18
<em><u>Divide both sides by 6:</u></em>
y = 3
<u>Answer-</u>
<em>The </em><em>exponential model</em><em> best fits the data set.</em>
<u>Solution-</u>
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,
<u>Linear Regression</u>

<u>Quadratic Regression</u>

<u>Exponential Regression</u>

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.
