Week 5 Individual Assignment Chapter 15 Supplementary Exercises, problems 1, 5, & 6 1. Let n ≥ 2. If xi is a Boolean variable for all 1 ≤ i ≤ n, prove that a) (x1 + x2 + ・ ・ ・ + xn) _ x1x2 ・ ・ ・ xn Assume the result for n _ k (≥ 2) and consider the case of n _ k + 1. b) (x1x2 ・ ・ ・ xn) _ x1 + x2 + ・ ・ ・ + xn Follows from part (a) by duality. 5. Let_be a Boolean algebra that is partially ordered by≤. If x, y, z ∈ _, prove that x + y ≤ z if and only if x ≤ z

A Diagnostic Analysis of the Lima Tire Plant Sabrina D. Foster American Military University Abstract This paper will provide a diagnostic report of the Lima Tire Plant. There are many problems within this company, and without them being properly addressed the company will continue to lose employees and production will continue to drop. The main problems that I see within this company are high turnover of the line foremen due to

Buiter Citigroup, London Abstract A fall in house prices due to a change in fundamental value redistributes wealth from those long housing (for whom the fundamental value of the house they own exceeds the present discounted value of their planned future consumption of housing services) to those short housing. In a closed economy representative agent model (the special

Maggy Schieffer BA 3352 – 004 HW 2 Chapter 2: 4. a. 80 carts/hr / 5 workers = 16 carts per hour per worker 84 carts/hr / 4 workers = 21 carts per hour per worker b. 80 carts/hr / ($10/hr *5(workers) + $40/hr (machine)) = 0.89 carts per $1 84 carts/hr / ($10/hr *4(workers) + $50/hr (machine)) = 0.93 carts per $1 c. The labor productivity is much greater after the new machine is introduced, increasing 5 carts per worker. In the multi factor productivity the number of carts

solution here. 2. (a) We should start by simplifying: f (x) = 3x2 (x + 2)(x − 1) 3x4 + 3x3 − 6x2 = = x3 − 8x2 + 16x x(x − 4)2 3x(x + 2)(x − 1) . Now, vertical asymptotes can potentially occur at zeroes of the de(x − 4)2 nominator of a rational function. So we set the denominator equal to 0: (x − 4)2 = 0 =⇒ x = 4. So x = 4 is a potential vertical asymptote. Because of our simplification, this should be a vertical asymptote, but we should look at lim f (x) to be sure. But x→4 216 . Already this is

Which is the best opportunity to pursue further? Darian Holdings Limited Why? Although 40% has already been taken up (leaving the founders with less skin in the game) and current European Logistics Companies are testing remote and unattended delivery solutions, there are several benefits for pursuing this opportunity: - The business addresses the hassle for both paying customers and logistics players – customers don’t have to wait for re-delivery date and logistic providers don’t have to dispatch

Definition: Consider an i.i.d. random sample X1, . . . , Xn, where each Xi has p.d.f./p.m.f. f (x). Further, suppose that θ is some unknown parameter from Xi. The likelihood function is L(θ) ≡ n f (xi). i=1 Definition: The maximum likelihood estimator (MLE) of θ is the value of θ that maximizes L(θ). The MLE is a function of the Xi’s and is therefore a RV. 2 7.31 MLE’s and MOM Easy Examples iid Example: Suppose X1, . . . , Xn ∼ Exp(λ). MLE for λ. L(λ) = n i=1 f (xi) = n

Trigonometric Functions of any Angle When evaluating any angle θ , in standard position, whose terminal side is given by the coordinates (x,y), a reference angle is always used. Notice how a right triangle has been created. This will allow us to evaluate the six trigonometric functions of any angle. Notice the side opposite the angle θ has a length of the y value of the given coordinates. The adjacent side has a length of the x value of the coordinates. The length of the hypotenuse is given
