The steps to predict the population of a place in the years to come.

1. Population
Predictor
By: Mikayla Kopp

2. Intro To Population
Predictor
• To begin to predict a population you must first
get your numbers of previous years. In this
project I used the years 1850, 1900, 1950, 1960,
1980, 1990, 2000 and 2010. We used all of these
numbers to predict the year 2060

3. Graph
Years and population
Pick two points that
best represent your
population growth

4. Work
Point One:
• First you pick two (110, 45,684,000)
points that best Point Two:
represent your (130, 53, 880,000)
growth.
• The you plug the
two points into the After plugging it in I got
Slope equation. the answer 409, 800

5. Work
• You then take your
first point and plug When plugging it into
Point Slope Formula the
it into Point Slope
answer I got was 606,000
Form.
• Your Slope answer
is M and your Point When plugging into
Slope answer is Y=Mx + B I got
your B.. Plug into Y=409,800x+606,000
Y=Mx+B

6. Finishing up your work
• Solve your 409,800(210)+606,000-
equation by
860,580,000+606,000=
placing you
861,186,000
number of years
in the place of X Y=861,186,000
Population Prediction of france in 2060 is
861,186,000

7. Intro
• Another way to predict your future
population is to plug it into a quadratic
equation.

8. Work
• Choose three points
Points:
from your chart on
(X1,Y1)=(0,36)
slide three. Round
(X2,Y2)=(50,41)
the to the nearest
(X3,Y3)=(100,42)
millionth.
• First plug in your
first point into the 36=ao2+bo+c
equation c=36
Y1+ax12+bx1+c

9. Work
• Then plug in C to 41=a(50)+b(50)+36
the equation and solve for A
plug in your next A=-0.008
set of points.
• Now that you have
42=a(100)2+b(100)+c
a and c use
B=-0.0292
elmination to find
your b

10. More Work
• After you have found all of your
points plug your numbers into
Y=Ax 2+Bx+C. The answer is what
you get after you plug in
everything and you plug in one of
your three points into X and Y.

11. Intro
• This next equation that we will solve
for will give us a log graph. You will
need two points.

12. Graph

13. Work
• The equation that
you will need for
this is Y=abx
• Then plug X and
41=ab50 and 42=ab100
Y into the
equation. You
should have two
equations so you
can plug in both
points.

14. Work
• After you have 41b50/=ab50/b50
your problem 41/b100=ab 100 /b100
divide b and your
exponent on both 41/b50=a and 42/b100=a
sides of each
equation
• Then place A in
the place of A 41/b50=42/b100

15. • Then Cross Answer=
Multiply 41b100 =42b 50
• Then divide by
b50 41b50=42
• Divide 41 on each 41b50/41=42/41
side b50=1.0243
• Get rid of the
exponent 50 b=1.0004803

16. Work
• Now plug in b
into the
equation and
solve 41=a(1.0004803)50
41/1.0242998=
• And then after a(1.0242998)/
plug in your 1.0242888
points to check a=40.02734
your math. You
got it right if it
is close to 41
