<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.
14 200 × 1,57 = 22 294
22 294 - 14 200 = 8 094
The increased +8 094 sales
Answer:
D.
Step-by-step explanation:
We have been an image of a right prism. We are asked to find the surface area of our given prism.
We will use surface area of prism formula to solve our given problem.
, where,
p = Perimeter of base of prism,
h = Height of prism,
B = Area of base of prism.
Now, we need to find the third side of triangular base of prism using Pythagoras theorem.
Upon substituting our given values in above formula we will get,
Therefore, the surface area of our given prism is 504 square units and option D is the correct choice.
If Bob can paint the fence in 4 hours, then in 1 hour he gets 1/4 of the fence painted. If Sarah can paint the fence in 2.5 hours, then she gets 2/5 of the fence painted in one hour (1/2.5 = 2/5). We add those amounts together and set them equal to 1/x, x being the the total time it will take them to paint the whole fence. 1/4 + 2/5 = 1/x. Find a common denominator first, then add the left side together. 5/20 + 8/20 = 1/x. 13/20 = 1/x. Cross-multiply to get 13x = 20 and x = 1.54 hours, just a bit over an hour and a half.
Answer:
6
Step-by-step explanation:
11x + 7 = 73
- 7 - 7
11x = 66
divide 66 by 11 and you get 6
