Answer: 1.509
Step-by-step explanation:
The formula of Margin of Error for (n<30):-
Given : Sample size : n= 22
Level of confidence = 0.99
Significance level : 
Using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have
Hence, the margin of error for a 99% confidence interval for the population mean =1.509
-5+25 is (20) and it’s in the parenthesis so it’s still connected by multiplication. your answer is 40.
The formula for the volume of a cone is V= πr² (h/3).
V= 3.14 (12²) (8/3)
V= 3.14 (144) (2.6...)
V= 1205.76
V≈ 1206
So the answer is A.
C and D because I just know
What you want to do is take 9 and multiply 9 by itself 5 times as shown (9*9*9*9*9) and you get 59049 then you take that number and divide it by 2 so 59049/2 is 29524.5
