Answer 1

what does weighted mean mean?

Answer 2

if the average of two colleges in georgia is 7700, how much does it cost to attend both schools total?

Answer 3

nooooo idea

Answer 4

multiply the number of schools by average cost

Answer 5

for both states

Answer 6

then add it up and divide it by the amount of schools there are- which is 5

Answer 7

you can think of it this way
each of the two schools in georgia cost 7,700 and each of the three schools in ny cost 9,400 so the total of all five schools is
\[2\times 7,700+3\times 9,400\] and the average is
\[\frac{2\times 7,700+3\times 9,400}{5}\]
