Answer: 3 hope this helped (:
Well first lets find the ROC (rate of change) in the sets of data.
1990 -> 134
2000 -> 139
so lets find the difference from the years given
2000-1990=10 so there is a 10 year gab
139-134=5 so there is a 5 million increase in the population
so divide 10 by 5 which gives us 2, so every year there is a 2 million increase in the population. so from 2000 to 2014 there is 14 years, so
14 x 2= 28, then add that to the latest population data
139+28=167
so the population in 2014 would be 167 million
Hope this helped!!
16-~7 make sure to leave the power 5 out
1) Plug the numbers into the equation for a simple interest rate. The equation is I = Prt, where P is the initial amount, r is the interest rate, and t is the time in years. 2) You have to turn the time into years, so put it over 12 (the months in a year) to turn it into a fraction for the unit of years, and plug in the equation to get I = 1200*0.81*(9/12). 3) Multiply this equation out to get 729.00, this is the answer. Answer: $729.00 interest. **TAKE THIS WITH A GRAIN OF SALT, you wrote the interest as dollars, but in this equation I assumed you meant to write it was a percent. If you did make a mistake and the 81 interest is a percent, then the math in this equation is correct. If it is an amount of money, then don’t copy it because it would be incorrect.
