Answer:
Part A: x = 6
Part B: S = 3.51

How to Find the Mean
Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
Calculate the mean of 2,3,4,5,8,8,12
Step 1: Add all the numbers together, to find the sum
2 + 3 + 4 + 5 + 8 + 8 + 12 = 42
Step 2: Count the number of values in your data set
There are 7 numbers
Step 3: Divide the sum by the count
42 ÷ 7 = 6
So the mean is 6
How to find sample standard deviation, look at the picture
The statement that -6 is in the domain of f(g(x)) is true
<h3>Complete question</h3>
If f(x) = -2x + 8 and g(x) = , which statement is true?
- -6 is in the domain of f(g(x))
- -6 is not in the domain of f(g(x))
<h3>How to determine the true statement?</h3>
We have:
f(x) = -2x + 8
Start by calculating the function f(g(x)) using:
f(g(x)) = -2g(x) + 8
Substitute
Set the radicand to at least 0
Subtract 9 from both sides
This means that the domain of f(g(x)) are real numbers greater than or equal to -9. i.e. -9, -8, -7, -6, ...........
Hence, the statement that -6 is in the domain of f(g(x)) is true

I think I solved the problem correctly.
24 + 88
88 + 24
( 88 + ( 24 ) )
( 24 + ( 88 ) )
