We will have the following:
First, we will have that the population change by:
So, the population changed by 703 people.
It took the follwoing number of years to change from 1431 to 2134:
So, it took 4 years to changes from 1431 to 2134.
The average population growth per year is of 175.75 people per year.
The population in 2000 would have been:
So, the population in 2000 would have been approximately 1429 people.
We will have that the equation for the population would be:
So, the equation would be:
Now, we predict the number of people of the town in 2014:
So, there will be approximately 3890 people of the town in 2014.
Using the concept of probability and the arrangements formula, there is a
0.002 = 0.2% probability that the first 8 people in line are teachers.
----------------------------------
- A probability is the <u>number of desired outcomes divided by the number of total outcomes.</u>
- The order in which they are positioned is important, and all people will be positioned, and thus, the arrangements formula is used to find the number of outcomes.
The number of possible arrangements from a set of n elements is given by:
----------------------------------
The desired outcomes are:
- First 8 people are teachers, in <u>8! possible ways.</u>
- Last 4 are students, in <u>4! possible ways.</u>
Thus,
----------------------------------
For the total outcomes, <u>number of arrangements of 12 people</u>, thus:
The probability is:
0.002 = 0.2% probability that the first 8 people in line are teachers.
