Answer:
The correct option is;
B) C(A(x))
Step-by-step explanation:
The given information are;
The cost to install the floor per square foot = $9
The area of the room is given by the function A(x) = x²
The function for the cost per square foot = C(A) = 9·A
We note that the total cost to install the wood floor = (The cost to install the floor per square foot) × (The area of the room)
∴ The total cost to install the wood floor = $9 × x²
Given that A(x) = x², we have;
The total cost to install the wood floor = $9 × A(x)
Also, given that C(A) = 9·A, we have;
C(A(x)) = 9·A(x)
Therefore;
The total cost to install the wood floor in dollar amount can be given by the function, C(A(x)) = 9·A(x)
Answer:
I am not sure if you were trying to find the mean- but if you are it is: 4
Step-by-step explanation:
For mean, you add all of the numbers and once you have that sum, you divide by the number of things you added.
Work:
1, 6, 6, 5, 2, 2, 0, 5, 6, 7
add all of those = 40
divide by 10 (because there are 10 things to add) = 4.
