Answer and Step-by-step explanation: Power Functions are of the form:
where a is scaling factor, which means, it moves the values of up or down;
and b is exponent or power, which determines the rate of growth or decay of the function.
The difference between exponential and power functions, is that in power functions, a variable base is elevated to a fixed exponent.
For that reason, Equations:
A.
B.
C.
D.
are NOT power functions.

Step-by-step explanation:
Given that a normally distributed set of data has a mean of 102 and a standard deviation of 20.
Let X be the random variable
Then X is N(102, 20)
We can convert this into standard Z score by
We are to find the probability and after wards percentage of scores in the data set expected to be below a score of 151.
First let us find out probability using std normal table
P(X<151) =
We can convert this into percent as muliplying by 100
percent of scores in the data set expected to be below a score of 151.
=0.71%
Answer:
10"
Step-by-step explanation:
The volume for a cube is V = l × w × h
But since this is a cube, all the sides aree the same length, so we could rewrite this in terms of x as:
V =
If we know the volume to be 1000, we sub it in for V:
We "undo" a cube by taking the cubed root of both sides. The cubd root of x cubed is just x, and the cubed root of 1000 is 10. Therefore, x = 10
