Short answer No.


Explanation

Suppose you have a sample of coins that have the date of production on them. They go from 1990 to 2000 inclusive. There are 100 coins in each year. That means there are 1100 coins because there are 11 years. Now you pick out 10 coins without replacement. Let's say all of them are from 1999. Then the mean is 1999.


If you start again and pick out 10 and get 3 years

4 from 2000

2 from 1995

4 from 1992


Whatever the mean is, it is not 1999. The mean of the second batch is 1995.8!

Answer:

Data from random samples will not always include the same values. Values are chosen randomly and they may or may not be the same. So means will vary among samples.

Step-by-step explanation:

Even though the data comes from the same population, different values are chosen with each sample.

Make an argument for why (4^2)^4=(4^4)^2
Eduardwww [97]
I hate when it comes to explaining but I gave it my best!

(4^2)^4 is the same as (4^4)^2 because they’re both being squared and multiplied by the a number equaling to the same number, but written differently.

4^2=16 , whereas 4^4=256
HOWEVER
16^4=65536 and 246^2=65536.

Therefore both equal to the same number. It depends on the exponents, and multiplication. If it were to be a different exponent, then they wouldn’t have been the same

How to find if two equations are inverses of each other?
Nady [450]
If you have 2 functions, f(x) and g(x), you would find f(g(x)) and g(f(x)). If, after you simplify both and you end up with just "x" as the answer, they are inverses of each other.  For example, f(x) = 3x - 2 and g(x) = (x+2)/3
f(g(x)) takes the g function and plugs it into the x in the f function, like this:
f(g(x))=3[ \frac{(x+2)}{3} ]-2
cancel out the 3's to get
f(g(x))=(x+2)-2 which is just x.  Now do it the other way: g(f(x))
g(f(x))= \frac{[(3x-2)+2]}{3}
3x-2+2 is 3x, so we have
g(f(x))= \frac{3x}{3} =x
See?
