Consider a photodetector in an optical communications system that counts the number of photons arriving during a certain interval. a user conveys information by switching a photon transmitter on or off. assume that the probability of the transmitter being on is p. if the transmitter is on, the number of photons transmitted over the interval of interest is a poisson random variable θ with mean λ, and if it is off, the number of photons transmitted is 0. unfortunately, regardless of whether or not the transmitter is on or off, photons may be detected due to "shot noise". the number n of detected shot noise photons is a poisson random variable n with mean µ, independent of the transmitted photons. let t be the number of transmitted photons and d be the number of detected photons. find l[t | d]

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
