Let's call this unknown number, x.
So then we can put together the equation using the information from the question:
Then we start by distributing this 10 to both the and the 6:
Then we subtract 60 on both sides:
Then we divide both sides by 5 to solve for x:
or
Answer:
The population mean is a true measure of the central tendency of the distribution of Y whereas the sample average is an estimator of the population mean.
Step-by-step explanation:
Out of all the statements given the correct statement is:
The population mean is a true measure of the central tendency of the distribution of Y whereas the sample average is an estimator of the population mean.
A sample mean is calculated from a dataset that is sampled out of the entire population data. And this sample mean is used to estimate or predict the population mean
Answer:
x= -11
Step-by-step explanation:
-2x-6+5x=-39
3x-6=-39
3x=-39+6
3x=-33
x= -11
The first integral has a well-known beta function representation, so the second one should too. The beta function itself is defined as
and satisfies the identity
Later on, we'll also use the so-called reflection formula for the gamma function; for non-integer z,
as well as the identity
Replace in both integrals, so that
Now replace :
So, the original integral (which I condense here to a double integral) is

Does anybody know the answer?
