Answer: B. x = 40
Step-by-step explanation:
The angles given are supplementary.
Supplementary angles are any two angles that add to 180 degrees, most commonly seen on one side of a straight line.
As these angles are supplementary, we can solve for x by adding both angles to get 180:
This means that the angle on the left is (3*40) + 15, or 135 degrees, while the angle on the right is 45 degrees. These angles add to 180 degrees.
The correct answer choice is B.
Answer:
.0942816
Step-by-step explanation:
Given
Sample size n = 150
Sample proportion =
= 0.28
Confidence interval = = .99
1 - confidence interval = 1 - 0.99 = .01
For 99 confidence interval
( Z = 2.576 )
= .0942816
