Answer:
B - x=5
Step-by-step explanation:
If y=25 is 250% more than y=10, so multiply 2 by 250% and you get 5
(f o g o h)(x) = f { g [ h(x) ] }
Which means: apply first function h, then apply function g to the result, and finally apply function f to the new result.
h(25) = √25 = 5
g(5) = 5 - 3 = 2
f(2) = 3(2) = 6.
Answer: 6

The formula for the confidence interval of the true mean is given by:
(1)
The degrees of freedom for this case is given by:
The Confidence level for this case is 0.95 or 95%, and the significance level
and
and the critical value is given by
Replcing into the formula for the confidence interval is given by:
For this case the confidence interval is given by :

Answer:
Real fifth root of 1024 is 4.
Step-by-step explanation:
We have to find the value of real fifth root of 1024.
For this let fifth root of 1024 = x
Therefore 
Or 
Therefore x = 4
X= 4 is the right answer.
