If the pool has 18 married and 22 not married, this means there are 40 people total
this means there’s a 18/40 probability that people who are married will be chosen
18/40 = 2/5
There is a 22/40 probability people who are un married will be chosen
22/40 = 11/20
so if 2 x 10 = 20, you can check your answer by dividing 20 by either 2 or 10
20 / 2 = 10
20 / 10 = 2

Step-by-step explanation:
The ratio of the number of square windows to the total number of windows represented as a rational number is
.
The ratio of an <u>amount a to another amount b</u> is given by:
![r = \frac{a}{b}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7Ba%7D%7Bb%7D)
- A fraction is a rational number.
In this problem, there are:
Hence, the ratio is:
![r = \frac{8}{17}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B8%7D%7B17%7D)

Answer:
Step-by-step explanation:
When interest compounds once per year, the formula for this is
where P is the initial investment, r is the interest rate at which it grows, and t is the time in years. Therefore, our model is
or simplified a bit:
![A(t)=6500(1.03)^t](https://tex.z-dn.net/?f=A%28t%29%3D6500%281.03%29%5Et)
