USE THE GIVEN FORMULA IN COMPLETING THE TASK.

FORMULAS BELOW ARE USED TO COMPUTE FOR POPULATION: POPULATION DENSITY population ) = Population Density area for example: 250,000,000 people ) = 8.06 people per square 31 000 000 sq. kilometer km. BIRTH OR DEATH RATES: # of births or deaths per year = Birth or Death Rate total population NOTE: to find Crude Birth/Death Rates, multiply the rate by 1,000 for example: 124,909 births 675, 543 = 0.18 = 18.49% birth rate people 185 = Crude Birth RateFINDING POPULATION GROWTH RATE (r): (This does not include immigration or emigration) crude births - crude deaths births - deaths =r % X 100 = r % 10 total population OR for example: 40 - 30 28,546 births - 24,389 = 1.0% deaths = 0.9% 10 455,387 total people FINDING THE DOUBLING TIME OF A POPULATION: THE RULE OF 70!! (This only applies if the population is growing exponentially) Why 70? It is 100 x In(2). What does that mean? Who cares...the math works! 70% 0.7 of r (in decimal form) = Doubling Time (dt) in years r (in percent form) for example: 70% 0.7 = 10 years 7% 0.07 FINDING FUTURE POPULATION FROM GROWTH RATE: ( initial population ) X ( growth rate ) years = Final Population NOTE: a growth rate of 3% is expressed as 1.03; a growth rate of 0.25% is 1.0025 for example: ( 468,843 people ) X ( 1.03 )10 years = 630,085 peopleDirections: Fill in the missing information in the table below.
