I have put together the math in words, please help me show the work in a math format. Info below Note 1,2,3
To find the population growth rate subtract the population of 2006 from 2007. Divide that answer by the 2006 population.
Australia’s growth rate from 2006 to 2007 was 0.67% per year.
1). 20,743,300 subtract 20,605,500 divided by 20,605,500 which equal the Population growth which is .00668 = 0.67%
2). 20,743,300 times .0067 equals the amount of growth of the population in 2007 which equals 138981
3). Find the approximate population which is 138981 + population of 2007 (which is 20,743,300) = 2008 population which is 20,882,281( 26 January 2008)
Using Australia data in the reference
20,882,281( 26 January 2008)
20,743,300 (26 January 2007)
20,605,500 (26 January 2006)
20,171,300 (26 January 2005)
Math assistance needed here.
The way I understand it is that ALGRBRA wants to have the steps above labeled 1) 2) and 3) in mathematical statements.
So....
1): Population growth = (20743300 - 20605500)/20605500
= .0066875
= .67%
2): amount of growth of the population in 2007 = 20743300(.67%)
= 20743300(.0067)
=138980
3): approximate population in 2008 = 138981 + 20743300
=20882281
BTW, all your populations were expressed in hundreds, so I would not leave my answers in the number form of your given data.
I would state the 2008 population as
20,882,300
Sure! Let me break down the steps for you in a mathematical format:
1) To find the population growth rate, we subtract the population of 2006 from the population of 2007 and divide it by the population of 2006.
Population growth rate = (Population in 2007 - Population in 2006) / Population in 2006
In this case:
Population in 2007 = 20,743,300
Population in 2006 = 20,605,500
So, the population growth rate = (20,743,300 - 20,605,500) / 20,605,500
= 137,800 / 20,605,500
≈ 0.00668
2) Next, to calculate the amount of growth of the population in 2007, we multiply the population in 2007 by the growth rate.
Amount of population growth in 2007 = Population in 2007 * Growth rate
= 20,743,300 * 0.00668
≈ 138,981
3) Finally, to find the approximate population in 2008 (specifically on January 26, 2008), we add the amount of population growth in 2007 to the population in 2007.
Approximate population in 2008 = Population in 2007 + Amount of population growth in 2007
= 20,743,300 + 138,981
= 20,882,281
Therefore, the approximate population in Australia on January 26, 2008, was 20,882,281.
I hope this helps! Let me know if you have any further questions.
