There are two fuses in an electrical device. Let X denote the lifetime of the first fuse, and let y denote the lifetime of the second fuse (both in years). Assume the joint probability density function of X and Y is f(x,y) = (x? + 2 + 2) 0<x< 1, 0 < y < 2 a. What is the probability that both fuses last at most 4 months? b. What is the probability that the first fuse lasts less than...
3. Let X denote the temperature (°C) and let Y denote the time in minutes that it takes for the diesel engine on an automobile to get ready to start. Assume that the joint density for (X,Y) is given by fxy(x, y) = c(4x + 2y + 1),0 < x < 40,0 < y = 2 (a) Find the value of c that makes this joint density legitimate. (b) Find the probability that on a randomly selected day the air...
There are two fuses in an electrical device. Let X denote the lifetime of the first fuse, and let y denote the lifetime of the second fuse both in years). Assume the joint probability density function of X and Yis f(x,y) – $(x +2y). 0<x<1, 0 <y<2 a. What is the probability that both uses last longer than 4 months? b. What is the probability that the second fuse lasts less than 3 months given that the first fuse last...

Let the market demand for widgets be described by Q = 1000 − 50P. Suppose further that widgets can be produced at a constant average and marginal cost of $10 per unit. a. Calculate the market output and price under perfect competition and under monopoly. b. Define the point elasticity of demand εD at a particular price and quantity combination as the ratio of price to quantity times the slope of the demand curve, Q/P, all multiplied by −1. What...

A firm has three factories each of which produces the same item. Let x, y, and z denote the respective numbers of units that are produced at the three factories in order to cover a total order for 2000 units. Hence, x +y+ z-2000 units. The cost functions for the three factories are ()200102 22003 (a) 200+10z Find x, y and z that minimize C, the total cost of production. Show that total cost is indeed the minimum at these...
