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)
i send u a picture of how i solve it. i hope this can help u
The ball followed a path modelled by the equation h = −0.001! + 0.5 + 2.5 where h is the height of the ball in feet and is the
distance in feet.

Answer:
Answer to first question is:
You can convert all fractions to decimals. The decimal forms of rational numbers either end or repeat a pattern. If the fraction is a mixed number, change it to an improper fraction. Divide the numerator by the denominator. If the division doesn't come out evenly, round the decimal off.
Answer to second question is: 0.222222
Answer to third question is: Yes
Step-by-step explanation:
Well the way I think of it is:
3/9 as a fraction is 1/3... so 1 divided by 3 equals 0.333333 repeating. You can even write it as:
_
0.3 with the fraction bar over it because it keeps repeating.
This goes for 2/9. All you have to do is do 2 divided by 9 and you get 0.222222 repeating. You can even write it as:
<h3>
_</h3>
0.2 with the fraction bar over it because it keeps repeating.
Hope this helps, have a good day. c;
