Differences between descriptive and analytical epidemiology
1. Descriptive epidemiology answers this questions who? what? where? when? Of the disease in an attempt to generate a hypothesis while analytical epidemiology is the studies that are conducted to test the hypothesis and give conclusions of a specific disease. Answers the questions why and how.
2. Descriptive epidemiology generates a hypothesis while analytical epidemiology tests the hypothesis.
3. Descriptive epidemiology identifies a group at a risk of a certain disease while analytical gives the cause of a disease.
4. No interventions are done in descriptive epidemiology while interventions are analyzed in analytical epidemiology
Similarities
1. They are both research design used in epidemiology.
2. Both study causes, the occurrence of a disease or health condition.
3. Outcomes from both aid in fulfilling epidemiology objectives.

Answer:
50 cm
Explanation:
Given that
Focal length of the mirror, f = 25 cm
Distance of the image, u = ?
Distance of the object, v = 50 cm
The formula for the focal length of a convex mirror is given by the relation
1/f = 1/u + 1/v,
where each of the parameters are exactly the same as what I've defined above. So now, if we plug in the values, we have
1/25 = 1/u + 1/50
1/u = 1/25 - 1/50
1/u = (2 - 1)/50
1/u = 1/50
u = 50 cm
So then, we can conclude that the size of the image is 50 cm
