The sample mean is an unbiased estimate of the population
mean. This tells us that the mean of all sample means is equal to the
population mean. Since we know that the population mean is 5.67, we also know
that the mean of sample means is also 5.67.
Answer:
![-6x^3y^5](https://tex.z-dn.net/?f=-6x%5E3y%5E5)
Step-by-step explanation:
![3xy^2\left(-2x^2y^3\right)](https://tex.z-dn.net/?f=3xy%5E2%5Cleft%28-2x%5E2y%5E3%5Cright%29)
Simplify
___________
Apply the negative rule
:
![-3xy^2\cdot \:2x^2y^3](https://tex.z-dn.net/?f=-3xy%5E2%5Ccdot%20%5C%3A2x%5E2y%5E3)
Add exponents :
![-3x^{1+2}y^2\cdot \:2y^3](https://tex.z-dn.net/?f=-3x%5E%7B1%2B2%7Dy%5E2%5Ccdot%20%5C%3A2y%5E3)
![-3x^3y^2\cdot \:2y^3](https://tex.z-dn.net/?f=-3x%5E3y%5E2%5Ccdot%20%5C%3A2y%5E3)
Add exponents once again :
![-3x^3y^{2+3}\cdot \:2](https://tex.z-dn.net/?f=-3x%5E3y%5E%7B2%2B3%7D%5Ccdot%20%5C%3A2)
![-3x^3y^5\cdot \:2](https://tex.z-dn.net/?f=-3x%5E3y%5E5%5Ccdot%20%5C%3A2)
Multiply the whole number by the variable expression :
![-6x^3y^5](https://tex.z-dn.net/?f=-6x%5E3y%5E5)

Answer:
{2, 3, 4, 5, 6}
Step-by-step explanation:
You are expected to determine the digits of the given number, then list them between curly brackets. Even if a digit appears in the number more than once, you need list it only once. It is helpful to sort the elements of a set, but not necessary.
__
The digits are 5, 3, 2, 6, 4, 6.
In sequence, the unique digits are 2, 3, 4, 5, 6.
The set of digits in the number is ...
{2, 3, 4, 5, 6}
_____
"Roster notation" means you simply list the elements of the set.
