Answer:
a. 
b. The symbol y-bar represents the average price of hotels in the area
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:
D)
Step-by-step explanation:
So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.
This problem shows 2/5 times 1/3 (Choice C). You can determine this by looking at the number of complete columns that are shaded out of the total number of columns(2/5). The look at how many complete rows are shaded out of the total number of rows shown(1/3). The overlapping part becomes the answer to the multiplication of these 2 fractions.
