In Exercise 3.101 on page 108, the price of a certain commodity (in dollars) and its total sales (in 10,000 units) were denoted by P and S. Use the joint density given in that exercise and the distribution function technique to find the probability density of V = SP, the total amount of money (in $ 10,000 units) that is spent on this commodity.
Answer to relevant QuestionsWith reference to Exercise 3.93 on page 107, find the probability density of the average mileage of two such tires. Assume independence. According to the Maxwell-Boltzmann law of theoretical physics, the probability density of V, the velocity of a gas molecule, is Where β depends on its mass and the absolute temperature and k is an appropriate constant. Show ...In a newspaper ad, a car dealer lists a 2001 Chrysler, a 2010 Ford, and a 2008 Buick. If the numbers of inquiries he will get about these cars may be regarded as independent random variables having Poisson distributions with ...If, d, the diameter of a circle is selected at random from the density function (a) Find the value of k so that f(d) is a probability density; (b) Find the density function of the areas of the circles so selected.
