Answer:
Provided that the sample size, n, is sufficiently large (greater than 30), the distribution of sample means selected from a population will have a normal distribution, according to the Central Limit Theorem.
Explanation:
1. As n increases, the sample mean approaches the population mean
(The Law of Large numbers)
2. The standard error of the sample is
σ/√n
where σ = population standard deviation.
As n increases, the standard error decreases, which means that the error
between the sample and population means decreases.
so this is how i was taught the inverse function. f(x) is basicly the same thing as saying y
so y=x over x+3
you switch the top x with y so it turns in to x=y over x+3
the problem should tell you what x equals so substitute x with the number it equals and then solve
here is an example f(x)=x over x+3 and x=14
x=y over x+3
14=y over 14+3
the inverse inverse function would probably be just solve the equation so just substitute the number they give you for x in for x
Do you have to find the area or perimeter?
Answer:
domain: all real numbers
range: y<-2
Step-by-step explanation:
I think its correct but already know the answer sooo yea
