Question

The table shows the approximate population of a town, in thousands, for the years 2009–2013.

Which is the best prediction for the town’s approximate population in 2025?

Use the data table to predict the population of a town for a given year.

100,000
115,000

Answer 1

@wolf1728 I like your picture. Do you think you could help me on this problem? :)

Answer 2

I'm working on it

Answer 3

Oh, ok. :) Thanks!

Answer 4

Seems as though the population growth runs from about 6% to 13% per year !!!
So, if we average that to about 10% per year that would make 2025 population about 213,000

Answer 5

I'm a bit confused...That's not one of the answer choices.

Answer 6

Are the answers 100,000
115,000 and so on?

Answer 7

Oh sorry. :) There the ones up top.

Answer 8

So it has to be one of these ?
100,000
115,000
120,000
130,000

Answer 9

Here are the population and the percent increase for each year

2009 46,000
2010 52,000 13.04%
2011 58,000 11.54%
2012 62,000 6.90%
2013 68,000 9.68%

Answer 10

Yes

Answer 11

So, if we have to guess the population for 2025, AND if we base it on the 2013 population AND if we choose the smallest possible growth rate then the
2025 population = 130,019 (5.55% growth)

Answer 12

2025 population = 120,041 (4.85% growth rate per year from 2013)

Answer 13

2025 population = 115,055 (4.48% growth rate per year from 2013)

Answer 14

2025 population = 110,006 (4.09% growth rate per year from 2013)

Answer 15

All set then, CrazyCountryGirl?

Answer 16

I think so, just to make sure...D? Right? :)

Answer 17

Yes is is D (or 130,000) IF it is based on a 5.55 % growth rate every year from 2013 through 2025

Answer 18

Well, I got a medal.
Thanks :-)

Refer to the least squares line fit and plot by Mathematica 9.
