Vilfredo Pareto (1848 - 1923) observed that most of the wealth of a country is owned by a few members of the population. Pareto's Principle is
log P = log C-klog W,
where W is the wealth level (how much money a person has) and P is the number of people in the
population having that much money.
A) Solve the equation for p
B) Assume k = 2.1, c = 9,000, and W is measured in millions of dollars. Use part (A) to find the
number of people who have $5 million or more
C) How many people have $15 million?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

the answer is 21%.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
