Sketch the curve of the following function and show all the work y=x/√(x²-1)

Show that if Y is a subspace of X, and A is a subset of Y,...

Show that if Y is a subspace of X, and A is a subset of Y, then the subspace topology on A as a subspace of Y is the same as the subspace topology on A as a subspace of X.

Suppose x,y ∈ R and assume that x < y. Show that for all z ∈...

Suppose x,y ∈ R and assume that x < y. Show that for all z ∈ (x,y), there exists α ∈ (0,1) so that αx+(1−α)y = z. Now, also prove that a set X ⊆ R is convex if and only if the set X satisfies the property that for all x,y ∈ X, with x < y, for all z ∈ (x,y), z ∈ X.

Sketch the region bounded above the curve of y=(x^2) - 6, below y = x, and above y = -x. Then express the region's area as on iterated double integrals and evaluate the integral.

Show that if (x,y,z) is a primitive Pythagorean triple, then X and Y cannot both be...

Show that if (x,y,z) is a primitive Pythagorean triple, then X and Y cannot both be even and cannot both be odd. Hint: for the odd case, assume that there exists a primitive Pythagorean triple with X and Y both odd. Then use the proposition "A perfect square always leaves a remainder r=0 or r=1 when divided by 4." to produce a contradiction.

Let X, Y be Banach spaces. Show that T ∈ L(X, Y) is continuous if and only if T is bounded.

PART A: Suppose X and Y are independent. Show that H(X|Y) = H(X) . (H represents entropy i think) PART B: Suppose X and Y are independent. Show that H(X,Y) = H(X) + H(Y) PART C: Prove that the mutual information is symmetric, i.e., I(X,Y) = I(Y,X) and xi∈X, yi∈Y

Let X, Y be independent exponential random variables with mean one. Show that X/(X + Y...

Let X, Y be independent exponential random variables with mean one. Show that X/(X + Y ) is uniformly distributed on [0, 1]. (Please solve it with clear explanations so that I can learn it. I will give thumbs up.)

Q1 (a) If k(x,y) and l(x,y) are 2 utility functions and are quasiconcave then show m(x,y)=min (k(x,y,),l(x,y) is also quasiconcave. (b) Show that k(x,y) is strictly quasiconcave if and only if the preference relation (>~) is strictly convex.

f(x,y)=30(1-y)^2*x*e^(-x/y). x>0. 0<y<1. a). show that f(y) the marginal density function of Y is a Beta random variable with parameters alfa=3 and Beta=3. b). show that f(x|y) the conditional density function of X given Y=y is a Gamma random variable with parameters alfa=2 and beta=y. c). set up how would you find P(1<X<3|Y=.5). you do not have to do any calculations
