suppose E[X]=2 and E[Y]=1. can we calculate E[XY]? explain why or why not?
Suppose E is the half-cylinder described by x^2 + y^2 = 1 between z = 4 and the xy-plane where y ≥ 0. Suppose further that the density at each point in E is proportional to the distance from the z-axis. (a) Find an expression for the mass of E as a triple integral. Then briefly explain why this integral is difficult to compute. (b) (8 points) Describe the solid E using cylindrical coordinates.Then express the mass of E as...

Suppose you measure the first particle from part (b) in the |0), |1) basis. What are the possible entangled? Explain why. particles are entangled? Explain why outcomes and their probabilities? On average, how many particles are entangled after the เงื่ measurement? a. Suppose that we have the state...
Part 1: Why do we need to create an E-ER model for an ER model? Explain the ‘overlap’ and ‘disjoint’ rules of E-ER model Part 2: You are creating a database for a college/university. Develop an E-ER Model with this given information: 1) Two specializations of Person: employee, student Person can be employee and/or student at the same time 2) Three specializations of Employee: staff, faculty, student assistant 3) Two specializations of Student: Graduate, undergraduate student Student...
Can you please explain the results of part A and B. Why in part A after we build the circuit in multisim we are getting 100V across every resistor and capacitor which in total is becoming 300V but when we calculate it we are getting 100V 100V and -100V. So why arent we getting -100V in multisim?
1. Consider the equation xy" - 2y' + (2 - x)y = 0,x > 0. We can easily verify that y(x) = e* is a solution of the equation. Use reduction of order to determine the general solution of the equation.
