Let n > 5. A deck containing 4n cards has exactly n cards each of four diffrent suits numbered from the set [n].
Using the method of choice and setting up appropriate subsets in how many ways can five cards be chosen so that they contain:
(a) five consecutive cards of the same suit? (ie. the set of numbers on the cards is [i, i + 4])
(b) four of the five cards have the same number?
(c) exactly three of the cards have the same
number?
(d) not more than two cards of the same suit?
Hint: consider two cases.
give a justification of answers pls (set notation, bijection principal, addition or multiplication theorem, cartesian product etc...)

Use duality to answer the following application.
The Enormous State University's Business School is buying
computers. The school has two models to choose from, the
Pomegranate and the iZac. Each Pomegranate comes with 400 GB of
memory and 80 TB of disk space, while each iZac has 300 GB of
memory and 100 TB of disk space. For reasons related to its
accreditation, the school would like to be able to say that it has
a total of at least 49,500 GB of memory and at least 12,500 TB of
disk space. If both the Pomegranate and the iZac cost $2,000 each,
how many of each should the school buy to keep the cost as low as
possible?
_________ Pomegranate(s) |
__________iZac(s) |
What are the shadow costs of memory and disk space?
memory | $______ per GB |
disk space | $________ per TB |

In all parts of this problem, assume that we are using fair, regular dice (six-sided with values 1, 2, 3, 4, 5, 6 appearing equally likely). Furthermore, assume that all dice rolls are mutually independent events.
(a) [4 pts] You roll two dice and look at the sum of the faces that come up. What is the expected value of this sum? Express your answer as a real number.
(b) [7 pts] Assuming that the two dice are independent, calculate the variance of their sum. Express your answer as a real number.
(c) [7 pts] You repeatedly roll two fair dice and look at the sum. What is the probability that you will roll a sum of 4 before you roll a sum of 7? Express your answer as a real number.
(d) [7 pts] What is the expected number of rolls until you get a sum of 4 or a sum of 7? (For example, if you get 7 on the first roll, the number of rolls is 1.) Express your answer as a real number.
(e) [7 pts] You roll 10 dice. Using the Chernoff Bound, give an upper bound for the probability that 8 or more of them rolled a 1 or a 2? You don’t need to calculate the value with a calculator (since you do not have one), but please write it in simplest terms.

A division of the Winston Furniture Company manufactures dining tables and chairs. Each table requires 40 board feet of wood and 3 labor-hours. Each chair requires 16 board feet of wood and 4 labor-hours. The profit for each table is $50, and the profit for each chair is $40. In a certain week, the company has 3200 board feet of wood available and 520 labor-hours available. How many tables and chairs should Winston manufacture to maximize its profit? (Let x represent the number of tables Winton manufactures and let y represent the number of chairs they manufacture.) (x, y) = What is the maximum profit? $

A committee of eight people, labelled a, b,...,h, has been split into the following eight
subcommittees:
{a,b,c,h},{c,d,e},{a,b,d,g},{c,d,e,f},{c,d,f},{b,d,g,h},{d,e,f},{c,e,f}
Is it possible for each subcommittee to choose from amongst its members a chairperson, so that nobody chairs more than one subcommittee? Justify your answer.

2 parts:
Solve the PDE using LaPlace Transforme: (A and B are constants)
(Part 1) ut = uxx, 0<x<l, t>0
u(x,0) = A,
ux(0, t) = 0,
u(l, t)= B
(Part 2) utt = uxx, 0< x < l , t >0
u(x,0) = ut(x,0) = 0
u(0,t) =0,
u(l, t)=A

Suppose we replace Incidence Axiom 4 with the following: Given any line, there are at least three distinct points that lie on it.
What is the smallest number of points in a model for this geometry? More precisely, find a number n such that every model has at least n points and there is at least one model that has only n points, and explain why your answer is correct.

Consider n numbers x1, x2, . . . , xn laid out on a circle and some value α. Consider the requirement that every number equals α times the sum of its two neighbors. For example, if α were zero, this would force all the numbers to be zero. (a) Show that, no matter what α is, the system has a solution. (b) Show that if α = 1 2 , then the system has a nontrivial solution. (c) Show that if α = − 1 2 , then there is a nontrivial solution if and only if n is even.

Blue Company sold 30,000 units of its only product and incurred a $85,000 loss (ignoring taxes) for the current year as shown here. During a planning session for year 2020’s activities, the production manager notes that variable costs can be reduced 25% by installing a machine that automates several operations. To obtain these savings, the company must increase its annual fixed costs by $175,000. The maximum output capacity of the company is 55,000 units per year. Blue Company Contribution Margin Income Statement For Year Ending December 31, 2019 Sales $900,000 Variable $680,000 Contribution Margin $220,000 Fixed Cost $305,000 Net Loss $(85,000) Compute the break-even point in dollar sales for year 2019. (Round your answers to 2 decimal places.) Compute the predicted break-even point in dollar sales for year 2020 assuming the machine is installed and there is no change in the unit selling price. (Round your answers to 2 decimal places.)

Let V be the set of positive reals, V = {x ∈ R : x > 0}. Define “addition” on V by x“ + ”y = xy, and for α ∈ R, define “scalar multiplication” on V by “αx” = x^α . Is V a vector space with these unusual operations of addition and scalar multiplication? Prove your answer.
