please circle the answer! (1 point) Let P be the vector space of all polynomials (of all degrees) with real coefficients. In this problem, we will consider the linear functions d: P + P and s: P +P defined by d(p(x)) = P(x), s(P(x)) = xp(x). In words, d is the function that takes the derivative of a polynomial, and s is the function that multiplies a polynomial by . (a) Let p(x) = -2.0° – 2.02 – 3+1 and...
1. For a polynomial p(1) = cktk + Ck-14k-1 +...+ci+co, and an n x n matrix A, we define p(A) = CkAk + Ck-1 Ak-1 + ... +CjA + col. Let A be an n x n diagonalizable matrix with characteristic polynomial PA(1) = (1-2)*(1-3)n-k where 1 <k<n - 1. In other words, let A be an n x n diagonal- izable matrix that has only 2 and 3 as eigenvalues. Explain what is wrong with the following false "proof...

Conditional expectations Let 2 - 0, 1)3, that is, all possible (ordered) triples of zeros and ones. Suppose that all outcomes have equal probability. We define three random variables Xi, X2, and X3 on this space representing the first, second, and third digit, respectively. We also define (i) Compute the values (across S2) of each of the following random variables: (i) What is the probability mass function of E(X2 X)
