Well, I know to find the mean you add all the numbers and divide it by how many numbers there were, so I'm guessing you just do that with the stem and leaf plot. I hoped this helped a bit
Is there a picture or is it just that
7 is digit for hundred thousands and 6 is for ten thousands so the answer is 800,000
The answer is 27.1052631579 or 27.1 if you rounded "m" to .10
