(20 Points) Given the joint probability density function of random variables X and Y as follow. $\qquad f_{XY}(x, y) = c$, within the shaded rectangle area, zero otherwise (a) Evaluate the value of constant \"c\". $\qquad \int_0^1 \int_0^2 dy dx \to \int_0^2 dx \to 2 \cdot c = 0 \implies c = \frac{1}{2}$ (b) Find out the marginal density functions of $f_X(x)$ and $f_Y(y)$. $\qquad F_Y(y) = \sum_i \frac{1}{i} \int dy \int dx |_{x_i} \qquad f_X(x_i) = \sum_i \frac{1}{i} g(x_i) f_X(x_i)$ $\qquad f_Y(y) = \sum_i \frac{1}{2} \qquad f_X(x_i) = \sum_i \frac{1}{2} \frac{1}{2(x_i)} f_{XY}(x_i)$ (c) Are X and Y independent? Justify your answer.

Help would be appreciated. Let aaa be the sequence defined by the following recurrence relation: a0 = 1 an = 2an-1 + 1 for n ≥ 1 Prove that an = 2n + 1 for any nonnegative integer n. Let bob be the sequence defined by the following recurrence relation: b0 = 12 b1 = 29 bn = 5bn-1 - 6bn-2 for n ≥ 2 Prove that bn = 53 + 7(2^n) for any nonnegative integer n. Let S be the set of perfect binary trees, defined as: Basic step: A single vertex v with no edges is a perfect binary tree. Recursive step: If T is a perfect binary tree, then a new perfect binary tree T' can be constructed by taking two copies of T, adding a new vertex v, and adding edges between v and the roots of each copy of T. Prove that h(T) = log2(nT + 1) - 1 for any perfect binary tree T, where nT is the number of vertices of T and hT is the height of T.

The Pell numbers are an infinite sequence of integers, which are the denominators of the closest rational approximations to the square root of 2. This sequence of approximations begins 1/1, 3/2, 7/5, 17/12, and 41/29. This sequence of numbers: (0, 1, 2, 5, 12, 29, 70, 169, 408, 985, 2378, 5741, 13860, 33461, ...) can be computed with the following recursive function: Pn = { 0 : if n = 0 1 : if n = 1 2 * Pn-1 + Pn-2 : otherwise } In SPIM, you will write the function int pell(int N) described above. N comes from the argument passed in register $a0. Your function returns the value in $v0. Note that pell(0) = 0, pell(1) = 1, pell(2) = 2, pell(3) = 5, pell(4) = 12, ..., pell(10) = 2378. Ensure you are not off by 1 in the sequence! Your program will prompt the user for a value of N. Your program will read in this integer N from the user and call your function pell(N). Your program will then print out the result.
