Answer:
Step-by-step explanation:
Answer: x-bar = y-bar = 0 whereas z-bar = 8/3
M= (c^2)/8 which is intern equal to 2
Step-by-step explanation:
Find the area, by setting the limits as
= 



Therefore;
Mxy= 
z-bar = 8/3
M= 8
dividing it into two volume gives us = 4
means 

c=2

Prime numbers are those that cannot be divided by another number (other than themselves and 1). In other words, prime numbers have factors of themselves and 1.
For example, 3 is a prime number because its only factors are 3 and 1.
6 is not a prime number because it can be factored to 3*2.
Therefore, the correct answer is c. 3,11,23,31
