I have a table with a data set #, and 2 variables (W and P) with values in the table.
Homework Equations
The equation (which I don't know what it means) says V= (summation with n on top and i=1 below Wi X Pi)/(summation with n on top and i=1 on bottom X Pi)
The Attempt at a Solution
What are the summations meaning and what do the subscript "i"'s mean?
