The prevalence rate shows the proportion of people that have a disease in a population and to be able to calculate it, you have to divide the number of people that have a disease by the population:

Prevalence rate=(5/1,000)*100

Prevalence rate=0.005*100

Prevalence rate=0.5%

According to this, the answer is that if there are five cases of H1N1 in the community of 1,000 people, the prevalence rate is 0.5%.

Answer:

B and C describe vertical angles

Step-by-step explanation:

Point R will be the common vertex of any possible pair of vertical angles.

For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.

For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.

Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.

Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.
