Question

In 1980 the population of alligators in a particular region was estimated to be 1200. In 2006 the population had grown to an estimated 5500. Using the Malthusian law for population growth, estimate the alligator population in this region in the year 2020.

Answer #1

In 1980 the population of alligators in a particular region was
estimated to be 1300. In 2008 the population had grown to an
estimated 7000. Using the Malthusian law for population growth,
estimate the alligator population in this region in the year 2020.
The alligator population in this region in the year 2020 is
estimated to be

In 1980 the population of alligators in a particular region was
estimated to be 1800. In 2005 the population had grown to an
estimated 5000. Using the Malthusian law for population growth,
estimate the alligator population in this region in the year
2020.

In
1980 the population of alligators in a particular region was
eatimated to be 1500. In 2007 the population had grown to an
estimated 7000. Using the Malthusian law for population growth,
estimate the alligator population in this region in the year
2020.
The
alligator population in this region in the year 2020 is estimated
to be __.

In 1990 the Department of Natural Resources released 1000 splake
(a crossbreed of fish) into a lake. In 1997 the population of
splake in the lake was estimated to be 3000. Using the Malthusian
law for population growth, estimate the population of splake in the
lake in the year 2020.

The population of a region is growing exponentially. There were
20 million people in 1980 (when t=0) and 70 million people in 1990.
Find an exponential model for the population (in millions of
people) at any time tt, in years after 1980.
P(t)=
What population do you predict for the year 2000?
Predicted population in the year 2000 = million people.
What is the doubling time?
Doubling time = years.

The population of a region is growing exponentially. There were
35 million people in 1980 (when t=0) and 70 million people in
1990.
Find an exponential model for the population (in millions of
people) at any time t, in years after 1980. P(t)=
What population do you predict for the year 2000? Predicted
population in the year 2000 = million people.
What is the doubling time? Doubling time = years.

The fox population in a certain region has a continuous growth
rate of 5 percent per year. It is estimated that the population in
the year 2000 was 23600. (a) Find a function that models the
population t years after 2000 (t=0 for 2000) (b) Use the function
from part (a) to estimate the fox population in the year 2008.

1) a) The fox population in a certain region experiences
exponential growth with a relative growth rate of 8% a year. In
2013, it was estimated that the population was 18, 000. (a) Find a
function that models the population t years after 2013. (b) Use the
function above to estimate the fox population in the year 2021. (c)
After how many years will the fox population reach 25, 000?
b) Two observers simultaneously measure the angle of elevation of...

Assume that farm sizes in a particular region are normally
distributed with a population standard deviation of 150acres. A
random sample of 50 farm sizes in this region is given below in
acres. Estimate the mean farm size for this region with 90%
confidence. Round your answers to two decimal places and use
ascending order.
