Particles are a major component of air pollution in many areas.
It is of interest to study the sizes of contaminating particles.
Let X represent the diameter, in micrometers, of a randomly chosen
particle. Assume that in a certain area, the probability density
function of X is inversely proportional to the volume of the
particle; that is, assume that
f(x) = c /(x^3) x ≥ 1
f(x) = 0 x < 1 where c is a constant.
a. Find the...
