Answer:
108 degrees
Step-by-step explanation:
Given
Let the angles be A and B


Required
Find the larger angle
If both angles form linear pair, then the following relationship exist:

Substitute values for A and B

Solve for x


Substitute 13.5 for x in







<em>Hence, the larger angle measures 108</em>
0.87= 87/100
But there is no choice even though it is the right answer
Answer is 87/100
Answer: (20.86, 22.52)
Step-by-step explanation:
Formula to find the confidence interval for population mean :-

, where
= sample mean.
z*= critical z-value
n= sample size.
= Population standard deviation.
By considering the given question , we have


n= 58
Using z-table, the critical z-value for 95% confidence = z* = 1.96
Then, 95% confidence interval for the amount of time spent on administrative issues will be :





Hence, the 95% confidence interval for the amount of time spent on administrative issues = (20.86, 22.52)
