Regression and modeling with functions

Mathematics
1 answer:
Leto [7]3 years ago
5 0
I used scatter plot graph in the insert graph function of excel and added a trend line that shows the equation of the line of best fit and the r. 

The line that can be applied in this function is linear with an equation of y = 3800.6x - 5223.6 and the regression is r² = 0.8925. The y intercept represents when the starting point of a line starts. It is a strong correlation since the value of r² that is equal to 0.8925 is close to 1. We can solve the value of the investment after 6 years using the equation above.

y = 3800.6x - 5223.6
y = 3800.6(6) - 5223.6
y = 17,580

The answer for this math problem
laiz [17]
Hi, We have a isosceles triangle.

Then,

There is two angles = (2x +2)°

As the sum of angles = 180° To the any triangle.

Then we wiil stay with:

(2x+2)° + (2x+2)° +(3x+1)° = 180°

Canceling °

2x+2+2x+2+3x+1=180

7x +5 = 180

7x = 180-5

7x = 175

Passing 7 dividing 175

x = 175/7

x = 25

This would be your answer!
