Answer:
Infinitly many solutions
Step-by-step explanation:
1 Expand.
3x+3+1+2x=4x+4+x
2 Simplify 3x+3+1+2x to 5x+4.
5x+4=4x+4+x
3 Simplify 4x+4+x to 5x+4.
5x+4=5x+4
4 Since both sides equal, there are infinitely many solutions.
Infinitely Many Solutions
M = - 2n - 2
3 ( - 2n - 2 ) + 5n = - 3
- 6n - 6 + 5n = - 3
n = - 3
m = - 2 ( - 3 ) - 2
m = 4

Answer:
Step-by-step explanation:
Hello!
A linear regression for the price of renting a room in a hotel and the rating said hotel received was calculated from a sample of n= 25 hotels.
The theoretical regression model is E(Y)= α + βXi
And the estimated regression equation is: ^Y= a + bXi
Where:
The estimator for the slope is b= 125
And the estimator of the Y-intercept is a= -400
So for this example the estimated regression line for the price of the hotel rooms given the ratings of the hotel is:
^Y= -400 + 125 Xi
^Y= represents the estimated average price of a hotel room
a= -400 is the estimated average price of a hotel room when the rating of the hotel is zero.
b= 125 is the modification of the estimated average price of a hotel room when the rating of the hotel increases one unit.
I hope this helps!
