2 answers:
Answer:
Infinite solution
Step-by-step explanation:
We are given an equation is identity
We have to find that how many solutions equation have
Identity equation:Identity equation is that true equation in which no matter what value is substitute for variable .It is always true statement.
Suppose that we have an identity equation
If this type of condition is obtained then we have infinite solutions.
So, if an equation is identity then the equation have infinite solutions.

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.
