Write solutions legibly, and show all work. Walk the reader through your thought process, using English words when necessary. 1. Recall question 2 of the previous homework – We draw 6 cards from a 52 card deck and let X = the number of heart cards drawn. You already found the pmf back then. You’re allowed to use it here without re-deriving it. a. What is the expected value of X? b. What is the variance of X? What is...

Some Extra Definitions Recall that, for a nonrandom real number c, and a random variable X, we have Var (cX) = e Var (X). In this problem we'll generalize this property to linear combinations! Let be a vector of real nonrandom numbers, and let be a vector of random variables (sometimes called a random vector). Last, define the covariance matrix to be the matrix with all the covariances ar- ranged into a matrix. When we talk about taking the taking...

I really need help with this python programming assignment Program Requirements For part 2, i need the following functions • get floats(): It take a single integer argument and returns a list of floats. where it was something like this def get_floats(n): lst = [] for i in range(1,n+1): val = float(input('Enter float '+str(i)+': ')) lst.append(val) return lst • summer(): This non-void function takes a single list argument, and returns the sum of the list. However, it does not use...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
