An investigator wanted to know whether chronic lymphocytic leukemia (CLL) had a genetic or environmental etiology. He knew that

rates in country X were higher than those in the United States. He decided to study the rates in the country of origin, in migrants, and in U. S. whites. He observed the following:
Population Rate Country X 50/100,000
Migrants from Country X to U. S. 10/100,000
U. S. whites 10/100,000

What are the reasons for this relationship?

Answer:

The cause may be environmental

Explanation:

The ratios show that ratio of incidence of chronic lymphocytic leukemia (CLL) in the population of country X is five times higher than the ratio in U.S. whites. However, the ratio of CLL in migrants from Country X to the U. S. is exactly the same as the ratio in U.S. whites. This relationship indicates that, rather than being genetic, the cause of CLL is more likely to be environmental.

anzhelika [568]

Answer:

Consumer surplus must rise

Explanation:

Remember, the Price ceiling is removed in a competitive market when there is a struggle to get many consumers.

If however the market price is not allowed to rise to the equilibrium level, quantity demanded would exceed quantity supplied, creating a shortage.

For example, several firms sells apple fruit at a price ceiling of $5, when the price ceiling is removed in this competitive market we would expect the firms to lower the price they sell their apples inorder to get more customers.

VikaD [51]

Answer:

$281,612

Explanation:

Plane Operating Cost = Fixed cost + (Variable cost per unit1 × q1) + (Variable cost per unit 2 × q2)

Plane Operating Cost = $40,190 + ($2709*88) + ($10 * 303)

Plane Operating Cost = $40,190 + $238,392 + $3,030

Plane Operating Cost = $281,612

So, the plane operating costs in the planning budget for August would be $281,612
