the question 7.1.17 along with the textbook solution is above,
however part (c) and (b) make little sense to me
7.1.17. Suppose that {λί, λ2, ,Ad are the eigenvalues for Anem and let (Ak, c be a particular eigenpair. σ (A), explain why (A_ÀI)-ic-c/(λ-A) (a) (b) For an arbitrary vector dnx, prove that the eigenvalues of For λ A+cd" agree with those of A except that λ, is replaced by A+ cdr and A agree except that λ, is replaced...
make sense to you intuitively? 4.4-14. Let X and Y be random variables of the continu- ous type having the joint pdf Draw a graph that illustrates the domain of this pdf (a) Find the marginal pdfs of X and Y. (b) Compute μχ, per, 07, σ3. Cov(X, Y), and p. (e) Determine the equation of the least square (c) Compute E that Y=y. (d) Find E(Y X (0, 1). Given t on the i y s t/2. sion line...
2) a) Find an expression for Cp in terms of Cy. Does this make sense? Explain. b) Calculate Co for a van der Waals gas in terms of V, T, and Cy. c) What are the dimensions of heat capacity? Does this make sense? Explain. d) At approximately the same latitude, a rain forest and a desert receive approximately equal free energy input from solar radiation per time. Why is the average temperature of a rain forest several degrees lower...

Let a,b be fa,b (a,b) = (1+ab)/3 0<=a<=1 , 0<=b<=2 0 otherwise a) Find pdf fa and fb b) Are a and b both indepent? explain why
Decide whether the following statement makes sense or does not make sense. Explain your reasoning. My daily food intake gives me about 10 million joules of energy. A. This statement makes sense because the typical adult consumes 1 calorie each day, which results in 10 million joules of energy. B. This statement does not make sense because one calorie equals 1000 joules. This results in eating 10,000 calories a day which is very unusual. C. This statement does not make...
2. Let X and Y be continuous random variables with joint probability density function fx,y(x,y) 0, otherwise (a) Compute the value of k that will make f(x, y) a legitimate joint probability density function. Use f(x.y) with that value of k as the joint probability density function of X, Y in parts (b),(c).(d),(e (b) Find the probability density functions of X and Y. (c) Find the expected values of X, Y and XY (d) Compute the covariance Cov(X,Y) of X...
