which parts do you need help in?

All of them

okay, in part a you need to describe how both of the sets have the same numbers, for example they have number 70 in common, that's how they overlap

for part , you need to find all the number in each data set for soil A and B, add all those numbers up and divide them by how many numbers there are, for example if you had the data set {90, 79, 66, 80} and you added them up to get 315, now you divide it by 4 since there are 4 numbers and you get 78.75, you understanding?

What do you mean for part a you describe what numbers they have in common? (I'm pretty dumb)
only_hanaaa
  • only_hanaaa
okay i already gave you the answer for part a, but ill explain...overlap means how to they have the same numbers, and you really don't have to describe the numbers i dont know why they put that in the question, but yea i think 70 is the only number they have in common but id check gain just in case...

@izzy529 Many math problems can be solve by starting to understand the terms used. Here the keyword is "stem and leaf plot". The moment you understand what the numbers in the plot mean, things will look MUCH easier. You can start by reading how a stem and leaf plot is constructed: http://www.purplemath.com/modules/stemleaf.htm Then write down the dataset (or interpret the plot) as two separate lists. The questions will then make a lot more sense. At that point, if you still have questions, please post again.
