Rv y z. F(R) is a type of modified gravity theory which generalizes Einstein's general relativity f(R) gravity is actually a family of theories, each one defined by a different function, f, of the Ricci scalar, RThe simplest case is just the function being equal to the scalar;. Example 5 X and Y are jointly continuous with joint pdf f(x,y) = (e−(xy) if 0 ≤ x, 0 ≤ y 0, otherwise Let Z = X/Y Find the pdf of Z The first thing we do is draw a picture of the support set (which in this case is the first. Proposition 1 For A ⊂ R2, P((X,Y) ∈ A) = Z Z A f(x,y)dxdy The twodimensional integral is over the subset A of R2Typically, when we want to actually compute this integral we have to write it as an iterated.

2 Independent rvs We’ll say that random variables are independent if their probability distributions factor, Pr(X = x,Y = y) = Pr(X = x)Pr(Y = y) If the variables are independent, then EXY = EXEY EXY = X x,y xyPr(X = x,Y = y) = X x X y xyPr(X = x,Y = y) = X x X y xyPr(X = x)Pr(Y = y) = X x xPr(X = x) X y yPr(Y = y) = X x xPr(X = x. If X and Y are independent, then E(es(XY )) = E(esXesY) = E(esX)E(esY), and we conclude that the mgf of an independent sum is the product of the individual mgf’s Sometimes to stress the particular rv X, we write M X(s) Then the above independence property can be concisely expressed as M XY (s) = M X(s)M Y (s), when X and Y are independent.

Connected sets A nonempty metric space \((X,d)\) is connected if the only subsets that are both open and closed are \(\emptyset\) and \(X\) itself When we apply the term connected to a nonempty subset \(A \subset X\), we simply mean that \(A\) with the subspace topology is connected In other words, a nonempty \(X\) is connected if whenever we write \(X = X_1 \cup X_2\) where \(X_1 \cap X.

Because the sound /z/ in Latin changed to /r/ by rhotacism in the fifth century BC, z was dropped and its place given to the new letter g In the 1st century BC, z was reintroduced at the end of the Latin alphabet to represent the sound of the Greek zeta /dz/, as the letter y was introduced to represent the sound of the Greek upsilon /y/.
