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)
Answer:
4(2x+7) which is equal to 8x+28
Perpendicular lines have negative reciprocal slopes. So if the slope is -2/5...to find the negative reciprocal, " flip " the slope and change the sign.
So we flip -2/5 and we get 5/-2...and now we change the sign...and we get 5/2. So our perpendicular slope will be 5/2.
Answer:
THE ANSWER IS 120
Step-by-step explanation:
AND SURE LETS TALKK
24-1 = 23
6-1/4 = 5 3/4
23/5 3/4 = 4
The constant is 4, so Vanessa is correct
The answer is:
D. Vanessa is correct because the quotient when dividing the values in the bottom row by the values in the top row is always 4.
