A)What was the mean population of the six continents or land masses that were habitable in 2000?
B) What was the mean population in 1950?
C) What was the percent incease in the mean population from 1950 to 2000?
What does this have to do with geometry?
A) If you mean the mean population per continent, divide the world population by 6. Total world population was 6.081 billion midyear
B) The midyear world population in 1950 was 2.556 billion
C) [(6.082-2.556)/2.556] x 100 is the percent gain over that period. It was much less than that PER YEAR
