Let R be the relation on N defined by xRy iff 2 divides x+y. R is an equivalence relation. You do not have to prove that R is an equivalence relation. True or False: 3 ∈ 4/R.
Determine if {(x,y) | x divides 2-y} is an equivalence relation on {1,2,3,4,5}. List the equivalence classes Determine if {(x,y) | x and y are both even or x and y are both odd} is an equivalence relation on {1,2,3,4,5}. List the equivalence classes.

Find the absolute maximum and minimum values of f(x, y) = x² + 4y? – 164 – 4 on D: the set of points (x, y) that satisfy x2 + y2 < 25. Part 1: Critical Points The critical points of f are: (0,2) M Part 2: Boundary Work Along the boundary f can be expressed by the one variable function: f = f(y) = (49-y^2)+9y^2-36y-3 Σ List all the points on this side of the boundary which could potentially...
Suppose that X ∼ Exp(3), Y ∼ Uniform [0,2], and that X and Y are independent. Find P(X^2 < Y ).
Find the exact solutions in [0,2). (1-sin(x))^2=3cos^2(x
10. Find the exact solutions in [0,27). (1 – sin(x))' = 3 cos?(x)
Let Θ be a continuous random variable uniformly distributed on [0,2 Let X = cose and Y sin e. Show that, for this X and Y, X and Y are uncorrelated but not independent. (Hint: As part of the solution, you will need to find E[X], E[Y] and E|XY]. This should be pretty easy; if you find yourself trying to find fx(x) or fy (v), you are doing this the (very) hard way.)
Let Θ be a continuous random variable...
