    Determining Number of Bits in MAR

    I'm trying to determine how many bits are required in the memory buffer register and in the memory address register given certain memory systems. For example, given the below system, how many bits are needed in MAR, and MBR if the memory is word addressable and how many bits if the memory is...

    Joint PDFs and Expected Values of 3 Cont Rand Vars

    So, in your equation, then just integrate \int_0^1 2x_3^2 dx_3 substituting that into the integral for x2, and then that result into the integral for x1? Actually, the explanation helped me out with another problem: f(x_1) = 2x_1, 0 < x_1 < 1 and f(x_2) = 4x_2^3, 0 < x_2 < 1 so...

    Joint PDFs and Expected Values of 3 Cont Rand Vars

    You know how sometimes, you take a long time to write a question, and then you submit, but it takes you to a login screen and then you lose everything you wrote? Anyhow...I would just like to verify some work here. The problems states that there are 3 mutually independent random variables...

    Continuous Functions of One Random Variable

    Big, fat facepalm going on over here... That's why I was so unsure of what I was getting. I was trying to integrate from 0 to infinity to check the PDF, which wasn't giving me 1. Stupid interval... Anyhow, thank you very much for the explanation. It helped out a lot. Off to practice...

    Continuous Functions of One Random Variable

    As in (θy-θ)/y ? As for that, am I missing 1/y, so I get (θ y-θ)/y ? Sorry if I'm not grabbing onto what your trying to say. The more I think about it the muddier I get.

    Continuous Functions of One Random Variable

    My problem is as follows (sorry, but the tags were giving me issues. I tried to make it as readable as possible): Let X have the pdf f(x)= θ * e-θx, 0 < x < ∞ Find pdf of Y = ex I've gone about this the way I normally do for these problems. I have G(y) = P(X < ln y) = ∫ θ * e-θx...
