The average of \(P\) numbers is \(x\) so the total = \(Px\)
The average of \(N\) numbers is \(y\) so the total = \(Ny\)
Final total = \(Px + Ny\)
Average = \(\frac{Px + Ny}{P + N}\)
Answer E
The average of \(N\) numbers is \(y\) so the total = \(Ny\)
Final total = \(Px + Ny\)
Average = \(\frac{Px + Ny}{P + N}\)
Answer E
