Step-by-step explanation:
a. The regression line equation is given by:
Where Alpha represents the slope, Beta represents the intercept with the Y axis, and epsilon represents the random component of the model. Thus,
y Obtaining:
.
b. In a simple linear regression model the value of y-bar represents the average of all values of y observed. Thus, since y represents the prices of the hotels, then y-bar is the average price of hotels in the area.
Answer:
Q-31=56
Step-by-step explanation:
Angle 1 and angle 2 are corresponding (they have an equal value). Set the two equations equal to each other, then solve.
40-4x=50-8x
+4x +4x
40=50-4x
-50 -50
-10=-4x
/-4 /-4
10/4=x
5/2=x
2.5=x
