A particular disease is tested for and the results determine that it occurs in about 1 of every 850 black males and about 1 of every 197,000 non-black males. Find the empirical probability that a randomly selected black male will have this disease.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
