Let's do the sum first:
x+4-8x+10 = x-8x +4+10 = -7x + 14
coefficient is the number beside the x.
so the coefficient for this sum is -7
D and B. They are both when they use 1/5 of something and then divide it into 10 parts
Answer:
Step-by-step explanation:
12 + 2x = 16
2x = 16 - 12
2x = 4
x = 4/2
x = 2
this is not pemdas...this is just an equation
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!
