<span>Naming of rays
Rays are commonly named in two ways:
By two points.
In the figure at the top of the page, the ray would be called AB because starts at point A and passes through B on it's way to infinity. Recall that points are usually labelled with single upper-case (capital) letters. There is a symbol for this which looks like this: AB This is read as "ray AB". The arrow over the two letters indicates it is a ray, and the arrow direction indicates that A is the point where the ray starts.
By a single letter. (I have not seen this done.)
The ray above would be called simply "q". By convention, this is usually a single lower case (small) letter. This is normally used when the ray does not pass through another labeled point.</span>

Answer:
$8,440
Step-by-step explanation:
5.5% of 8,00 = 440
8,000 + 440 = 8,440
1200 + 108 = 1200( 1 + 0.03x)
1308 = 1200 + 36x
36x = 108
x = 3 years
Answer:
The probability that a person with the marker develops cancer is 0.0725.
Step-by-step explanation:
Let's denote the events as follows:
<em>A</em> = a person has cancer
<em>B</em> = a person carries the marker.
<u>Given:</u>
P (A) = 0.03
P (B) = 0.12
P (B|A) = 0.29
The conditional probability of an event <em>X</em> provided that another event <em>Y</em> has already occurred is:
Use the conditional probability formula to compute the probability that a person with the marker develops cancer.
Thus, the probability that a person with the marker develops cancer is 0.0725.
