Answer:
C. (f - g)(x) = 3ˣ - 2x + 14
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
- Function Notation
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3ˣ + 10
g(x) = 2x - 4
(f - g)(x) is f(x) - g(x)
<u>Step 2: Find (f - g)(x)</u>
- Substitute: (f - g)(x) = 3ˣ + 10 - (2x - 4)
- Distribute -1: (f - g)(x) = 3ˣ + 10 - 2x + 4
- Combine like terms: (f - g)(x) = 3ˣ - 2x + 14
It’s 3 because it just is okay math is hard
Answer:
Step-by-step explanation:
Data given
represent the sample mean obtained
represent the sample deviation obtained
represent the true mean (variable of interest)
n=400 represent the sample size selected
Solution to the problem
The best estimator for the true mean 
is given by the sample mean 
, and the reason is: If we assume that in tha random sample 
each observation follows a normal distribution like this:
Then when we find the expected value for the sample mean we have this:
If we use the properties of the expected value we have:
And since the expected value of each observation is the same we have:
So then we have that the best estimator for the population mean is given by:
Base=B
Area=A
is that what you mean
Answer:
length=92yd
width=49yd
Step by step:
2l+2w=282
l=2w-6
Plug in l
2(2w-6)+2w=282
4w-12+2w=282
6w-12=282
6w=282+12
w=294/6
w=49
Then plug in w
2l+2(49)=282
2l+98=282
2l= 184
l=92
