Since the value is taken from a population, the value is a parameter.
<h3>Parameter and Statistic:</h3>
- If the information is taken from a sample, it is called a statistic.
- If the information is taken from a population, it is called a parameter.
For this problem, the students of the class are the population, as all students are considered for the calculator of the mean, hence the value is a parameter.

If there is some scalar function
such that

So the vector field

is given by
In this case,
Answer:x=1/108 is your answer
-5/6x-1/9x=-102
1/x(-5/6-1/9)=-102
1/x=-102/(-17/18)=-102×-18/17=108
x=1/108
Answer
n = 30
Explanation
To solve for n, you have to isolate it by 'getting rid' of the 18, 2, and negative sign.
You 'remove' these numbers in backward PEMDAS.
So to 'remove' the 18, you subtract both sides by 18.
3-18 = -15
-n/2+18-18 = -n/2
So now you are left with -15 = -n/2.
To 'get rid' of the 2, you multiply each side by 2.
-15×2 = -30
-n/2×2 = -n
And now you have -30 = -n.
To 'get rid' of the negative sign, you multiply both sides by -1.
-30×-1 = 30
-n×-1 = n
So you get 30 = n or n = 30.
If you still have questions I'll answer them in the comments (under this question).
