Answer 1

Answer:

pls mark me as brainliest

Step-by-step explanation:

Average is the sum of the data values divided by the total number of data values.

Given that average of m numbers is n2

n2=msum of m numbers

Therefore, sum of m numbers =mn2

Given that average of n numbers is m2

m2=nsum of n numbers

Therefore, sum of n numbers =nm2

Therefore, average of (m+n) numbers is m+nmn2+nm2=m+nmn(m+n)=mn
