We have been given that the ages of students in a school are normally distributed with a mean of 15 years and a standard deviation of 2 years.
We are asked to find the percentage of students that are between 14 and 18 years old.
First of all, we will find z-score corresponding to 14 and 18 using z-score formula.
Similarly, we will find the z-score corresponding to 18.
Now we will find the probability of getting a z-score between and
that is
.
Using normal distribution table, we will get:
Let us convert into percentage.
Therefore, approximately of the students are between 14 and 18 years old.
Answer: About 800 thousand
The more accurate value is 807,528 but this is also an approximation.

Work Shown:
That's the rough population of wild pigs (in millions) for the year 2000.
Multiply by to get it in terms of units instead.
There were roughly 800 thousand wild pigs in the year 2000.
What is the result of isolating y^2 in the equation below (x-2)^2+y^2=64?
Solution:
We want to isolate from the equation
To isolate , we must try to get
alone
So, We must subtract from both sides
