Logic is basically human reasoning that tells us if certain proposition or declarative statement is true.

(a)There are five boards of directors (kojo, kofi, menash musah, and mawule) of a School. The board of director kojo owns 10% shares, kofi owns 30% shares, mensah owns 20% shares, musah owns 25% shares and mawule 15% shares of the total shares. For the adoption of the particular policy to be passed in the board’s meeting more than 66% should vote in favour of the policy. The weightage to the votes depend upon the percentage shares owned by the directors. In the board’s room each director has a switch which he turns ON if votes in favour of policy. Design a switching circuit to ring a bell if policy is accepted in the board’s meeting. Only the NAND gates should be used to realize the circuit.

(b) What is a universal gate? Give examples. Realize the basic gates with any one universal gate.

Suppose you were attending a university where students hated the bookstore and their aggressively high prices. Suppose further that a student organization goes to the bookstore and argues that prices of text books are exceeding $150 per class. At such outrageous prices, students can no longer afford to go to school. The college bookstore claims that an average student pays $101.75 per class for texts (far below the stated claim of $150). A student group randomly selects ten courses from the catalog and finds the costs for each: $140, $125, $150, $124, $143, $170, $125, $94, $127, and $53.

a. Is that enough to justify a claim that the bookstore is underestimating the amount spent? Make sure that you show your work.

b. Students decide to take a sample from one more class and find that this class has a textbook cost of $195. Does adding this observation to the other 10 observations change your answer to part (a) above?

You have just turned twenty-six years of age and feel it is necessary to upgrade your qualifications. After some consideration, you feel that undertaking full-time study for an MPA degree at the Fletcher School is one alternative. For the two years of full-time study, tuition and living expenses will be $55,000 per year. In addition, you will have to give up your current job with a salary of $75,000 per year. Assume all cash flows occur at the end of the year. Assume a real interest rate of 3% per year, ignoring taxes. Also assume that the salary increase is a fixed real amount that starts after you complete your degree (at the end of the year following graduation) and lasts until retirement at age sixty-five. In order to justify the investment, by how much does your salary have to increase as a result of getting the MPA degree?

4. Two randomized-controlled trials of routine ultrasonography screening during pregnancy were carried out, to see whether routine ultrasound imaging influenced outcomes of pregnancy such as birthweight and mode of delivery. No significant differences were found. At ages 8 to 9 years, 2011 singleton children of the women who had taken part in these trials were followed up. Ultrasonography had actually been carried out on 92% of the ‘screened’ group and 5% of the control group. No significant differences were found in scores for reading, spelling, arithmetic or overall school performance. A subgroup of children underwent specific tests for dyslexia. The test results classified as dyslexic 21 of the 309 children in the screened group (7%, 95% confidence interval = 3-10%) and 26 of the 294 controls (9%, 95% CI = 4-12%]). (Lancet 1991; 339: 85-89.) a. What is meant by “randomized” and “controlled”? Why were these techniques used?

MARKOV ANALYSIS

An IE student falls in line i a copier machine to reproduce his materials. Students arrive according to exponential distribution process at a mean time of 20 minutes. The copier operator can finish reproducing the materials  according to exponential distribution at a rate of 5 per hour.

a) What is the probability that exactly 5 students fall in line in the copier machine. Answer in 4 decimal places.

b) What is the approximate time in minutes student will fall in line? Answer in integer value.  

c) How many students will be falling in line to avail of the service of the copier operator? Answer in integer value.  

d) If the school administrator wants to limit students' waiting time to 2 minutes, how many copier machines should be installed? Answer in integer value.  

e) What is the waiting time (in minutes) if the number of copier machine will be installed based on your answer in (d). Answer in 3 decimal places.  

For the following positions, match sources and methods to recruitment. Assume that in all cases you must use external recruitment to fill the position. Justify your choices.

a. Computer programmer

b. Maintenance worker

c. Illustrator

d. Postdoctoral researcher

e. CEO

Note: Managers must first identify the source (where prospective employees are located, for e.g colleges, universities, military personnel etc.) before choosing the method (how to attract them for e.g advertising, internships, job fairs etc).

An example is provided below to guide you to solve the question:

Computer Programmer:

Source: Potential candidates for computer programmers can be recruited from School, College, Universities, Programs etc

Method: Potential candidates for computer programming can be recruited through means of Advertisements, Internships etc

(This is just an example provided above for your clarification, the answer that i need should be properly elaborated and explained)

Answer to the questions based on your knowledge about positive psychology and happiness theory (PERMA-model; P+E+M) plus the character strengths model.

Obama is driving in his car and suddenly his car starts to make a weird sound:

Obama: “Oh no! The muffler sounds bad… What if I have to take it to the maintenance shop?... I can’t afford the expense… I’d have to draw the money from Jamie’s college fund… What if I can’t afford his tuition?... That bad school report last week… What if his grades go down and he can’t get into college?...Muffler sounds bad…”

… And so Obama’s worrying mind spins on in an endless loop of ruminating thoughts, and it’s causing him lots of negative emotions.

• Describe in details - step by step - how Obama should conquer his worrying mind in order to feel more energized and hopeful.

I would like to see a PowerShell script(for purely inspirational work to use as an inspiration for helping to develop my skills as a hobby.

*** This should all be done in a loop **

Before beginning, You will need a simple text file with three weeks of scores between Michigan and Michigan State. Example:

UM21, MSU 14

UM28, MSU 35,

UM14, MSU 3

1) Then I need a loop that reads in the attached text file

2) Read the scores by school and determine if MSU or Michigan won or lost

3) - if the wolverines win, have user put the score into the win file (win.txt)

                ** UM win over MSU55-10 **

    - if the wolverines encounter a loss, put the score in the loss file (loss.txt)

               ** wolverines lose to spartans 24-17 **

  NOTE: the permission must be changed on the file in order to write to it

  *** the file permission switching must be done in separate script ***

4) please zip contents of wolverines and sparty directories
