Question

The line plot shows the weight of stones found in a stream.what is the average weight of the stones

Answer 1

Because you haven't given the data, the only thing I can tell you is how to calculate the average weight:

Add all of the different weights recorded and divide it by how many numbers there are.

For example:

40, 30, 20, 10

40+30+20+10=100

100/(how many numbers there are)=100/4=25

Hope this helps!
