There were 100 new cases of syphilis last year in a given population of 100,000 people. At that time, 500 people in this population already had syphilis. The incidence of syphilis in this population is __________.
a. 100 per 100,000
b. 500 per 100,000
c. 1000 per 100,000
d. 5000 per 100,000
Answer:
a. 100 per 100,000
Explanation:
Incidence rate of a population can be defined as the rate at which an disease occurs in a population.
The incidence of a population is calculated as
The number of new cases ÷ The population of the people
From the above question,
The number of new cases = 100
The population of the people = 100,000
The incidence = 100 ÷ 100,000
The incidence of syphilis in the population is 100 per 100,000
Answer:
100 per 100,000
Explanation:
False
The answer is 2 raccoons per square meter.
The math is very clear. It can be solved using proportion.
If 20 raccoons live in 10 square meters, how many of them will live in 1 square meter:
20 raccoons : 10 m² = x raccoons : 1 m²
⇒
⇒ x =
⇒ x = 2
So, a population density is 2 raccoons per square meter.
