Given value:
find:
Sample mean=?
Answer: No, it is not.
Step-by-step explanation:
In order to solve this exercise it is important to remember the definition of "Integers".
Integers are defined as those numbers that do not have a fractional part. Integers contains:
1. The positive numbers (these are the numbers greater than zero):
2. The negative numbers (these are the numbers less than zero):
3. The zero:
It is also necessary to remember the definition of "Decimal numbers".
Decimal numbers are those numbers that have a whole part, a fractional part and a point that separates these parts. That point is called "Decimal point".
Then, given the following number:
You can identify that it has a whole part and a fractional part separated by the Decimal point. Therefore, that number it is not an Integer.
Answer:
7^5 (the arrow means it is an exponent)

Answer: (y-2)(y-7)</h3>
=====================================================
Explanation:
To factor this, we need to find two numbers that
- A) multiply to 14 (last term)
- B) add to -9 (middle coefficient)
Through trial and error, you would find that the two numbers are -2 and -7
-2*(-7) = 14
-2 + (-7) = -9
So that's why the given trinomial factors to (y-2)(y-7)
You can use the FOIL rule to go from (y-2)(y-7) back to y^2-9y+14 again.
