Answer:
30°  is one of the degree measures of the angles.
Hence, option (A) is true.
Step-by-step explanation:
- Let 'x' be the degree measure of the first angle.
Given that the degree measure of one of two complementary angles is twice that of the other.
- Thus, the other angle = 2x
<em><u /></em>
<em><u>Complementary angles</u></em>
- We know that two angles are termed as complementary angles when the sum of their measured angles is 90°.
Thus the equation becomes
x + 2x = 90°
3x =  90°
Divide both equations by 3
3x/3 = 90°/3
x = 30°
Therefore, 30°  is one of the degree measures of the angles.
Hence, option (A) is true.

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
 y  Obtaining:
  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.
