What was the percent increase in the mean population from 1950 to 2000?
1950 mean: 426,000,042.5
2000 mean: 1,046,500,000
Do I divide the mean for 2000 by the mean for 1950?
no, you want the percent of the increase
so subtract the two populations, then divide that by 426,000,043
First of all, the population mean does not need to be carried out to more than the nearest whole number. (Where would you find .5 of a person?)
Since it is asking for the percent increase, you would take the difference between the two and divide by the 1950 number (rounded off).
I hope this helps. Thanks for asking.
I get 1.477 % is that correct?
1,046,500,000 minus 426,000,043 = 620,499,957 รท 420,000,043 = 1.4777
no
1.477 = 147.7%
(didn't the population more than double ??)
to change a decimal to a percent, move the decimal place two spots to the right (you are multiplying by 100)
