1. Hi everyone. I'm looking for help with converting this function to quadratic form. 2. The function is f(x1,x2)=(x2-x1)^4 + (12*x1*x2) - x1 + x2 - 3. The quadratic form I need to convert to is: f(x)=(1/2)x'Qx - x'b + h where x is a vector=[x1 x2]', '=transpose, Q and b are...

For M/M/1, given that arrival rates is Poisson with mean L and service (exit) rate is Exponential with mean U, I would think that the probability of getting an additional person in the next state is L and losing a person in the next state is U, which is just from logic. I'm not sure how to...

My initial thought is to multiply L and p together to get a basic "success" rate, then divide by M, but there's no way this is that simple. I am not sure what the correct way is to solve this problem.

Thanks, I'm working on that and it looks likes since X and Y are independent, I would be able to add them together in the denominator for the new mean (1/(x+y)). Does anyone know about the Markov part? That sort of came out of nowhere.

I am having trouble solving this problem. I'm not sure how to solve this problem... Assume X and Y are independent exponential random variables with means 1/x and 1/y, respectively. If Z=min(X,Y): Is Z exponentially distributed as well (if so, how do you know)? What is the expectation of Z...

I have a Poisson-based question that I am not sure how to approach and solve. A processor receives groups of bits with a Poisson arrival rate of L. The probability of an error in receiving an erroneous bit is p. The number of bits in a group of bits is Poisson with mean M. If there is no error...
