Answer 1

Answer:

Hey Hi

here is your answer

Change in population

= population in 2002 - population in 1997

= 1.28 x 10^9 - 1.24 x 10^9

= 10^9(1.28 - 1.24)

= 10^9(0.04)

Thus

% Change

= {Change/Population in 1997} x 100

= {10^9(0.04)/1.24 x 10^9} x 100

= {0.04/1.24} x 100

= 4/1.24

= 3.22 % is your answer

Thanks
