- A raptured pipe in a North Sea oil rig produces a circlar oil slick that is y meters thick at a distance x meters from the rapture. Turbulance makes it difficult to directly measure the the thickness of the slick at the source (where x=0), but for x >0, it is found that y= 0.5(x2+3x)/x3+x2+4x. Assuming the oil slick is continiously distributed, how thick would you expect it to be at the source?A random variable X has a pdf f(x) = { kex, x<0 0 , otherwise } Determine the value of k, and find V(x).Let X1, X2 denote two independent variables, each with a x^2(2) distribution.
