A 10-year study (lasting from January 1, 2008 to December 31, 2017) was conducted examining the risk of developing lung cancer a
mong a group of 5 participants who were all exposed to asbestos without proper personal protective equipment when working in retrofitting old buildings. On the date the study began, the 5 exposed workers were enrolled and all screened negative for lung cancer. Since cancer can take time to develop, the workers were followed for 10 years and were re-screened at the end of each year (December 31st). The following represents the information the researchers collected from each of the 5 participants.
a. Calculate the prevalence of cancer on January 1, 2017 in the high-risk sample.
b. Calculate the incidence of cancer between January 1, 2017 – January 1, 2018 in the high-risk sample.
c. Calculate the prevalence of cancer on January 1, 2018 in the high-risk sample.
a. Calculate the prevalence of cancer on January 1, 2017 in the high-risk sample.

Answer:
(2,4)
*View attached graph*
Step-by-step explanation:
2x + 3y = 16
2 + 2y = 10
2 + 2y = 10
-2 - 2
2y = 8
/2 /2
y = 4
2x + 3y = 16
2x + 3(4) = 16
2x + 12 = 16
- 12 - 12
2x = 4
/2 /2
x = 2
(x,y) -> (2,4)
Hope this helps!
