Answer:
See explanation below.
Step-by-step explanation:
The average is measure of central tendency that is also called sample mean and is calculated from the following formula:

This is an estimator of the population mean and is unbiased since the expected value for the estimator is the same parameter as we can see here:

And is important because is the most common measure of central tendency reported on any study.
Is important to remember that this measure can be affected by outliers , for this case when we have outliers is better use the median as a measure of central tendency
Answer:
Step-by-step explanation:
One of the most important things to understand about lines is the definition of slope. Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.
Answer is 3 because when you solve its 3 or less
Answer:
1/15
Step-by-step explanation:
This is probably too late but I'll do it anyway.
There are 10 cards in all.
of the 10, 3 are green.
So your chance of drawing the first green is 3/10
Now you have 9 cards in total left.
Two of them are green
Your chance of drawing a green card again is 2/9
Your total chance of drawing 2 green cards is
2/9 * 3/10 = 6/90
2/9 * 3/10 = 1/15
