Te difference of 2 standard deviation of a population n1 & n2 is given by the formula:
sigma (difference)=√(sigma1/n1 + sigma2/n2), Plug:
sigma(d)= √(49/100 + 36/50)
Sigma(d=difference) =1.1
Answer:
the mean is 9.
Step-by-step explanation:
<h2>mean=<u>4+4+5+6+8+9+27</u></h2>

Answer:
A exterior angle of a polygon is an angle outside the polygon formed by one of its sides and the extension of an adjacent side.
To answer this question here is what you would do. I can't give you the exact answer because there is not a line plot attached.
Count the number of X's above the number 5 1/2 feet. Put this number over the total number of X's you count (including the 5 1/2s).
This is your answer when you write these 2 pieces of information in fraction form.
For a polygon to be regular it must have all sides the same length and all interior angles the same.
