Answer: A
Step-by-step explanation:
By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.
(2x+3)+25=3x-17 [combine like terms]
2x+28=3x-17 [subtract both sides by 2x]
28=x-17 [add both sides by 17]
x=45
Now, we know that the answer is A.
Answer:
(4x+9)-(16x+9) = 4x+9-16x-9
= -12x
Answer: (67,87)
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where 
is the sample mean and E is the margin of error.
Given : Sample mean : 
Margin of error : E=10
Then, the confidence interval for population mean will be :-
Hence, the confidence interval for population mean =(67,87)
