Angle C would be 55 degrees. A straight line is 180 degrees so you would do 180-125 which equals 55. Hope this helps!
Answer:
A
Step-by-step explanation:
Simple linear regression is a statistical method that summarizes and study relationships between two continuous quantitative variables.
One variable is regarded as the predictor, explanatory, or independent variable and the other variable is regarded as the response, outcome, or dependent variable.
Two variables can be denoted by X and Y.
Among the given options, the correct option is A. After conducting a hypothesis test to test that the slope of the regression equation is nonzero, you can conclude that your predictor variable, X, causes Y
The diameter is given which is 13.5feet and radius is half of diameter. Therefore radius = 6.75 feet.
Slant height = 16.8 feet
The formula of surface area of cone is

Correct option is C
See the attached picture:
6% = 1200
9% = 2400
12% = 3800
6,00 because you have to add them up then divide the the last nimber and you should get 6,000
