Given an array of monthly rainfall that covers some number of years

(where each column is a month and each row is a year)

create a function YEARLY that prints the average rainfall for each year

For example, if the information below were to be stored in a 5x12 matrix RAIN...

     J F M A M J J A S O N D
2003 1 2 1 2 1 2 1 2 1 2 1 2
2004 1 1 1 1 1 1 1 1 1 1 1 1
2005 2 2 2 2 2 2 2 2 2 2 2 2
2006 1 2 3 1 2 3 1 2 3 1 2 3
2007 5 1 2 4 3 3 5 1 2 4 3 3

Then the function YEARLY(RAIN) would print the result

average rainfall for year 1 is 1.500000
average rainfall for year 2 is 1.000000
average rainfall for year 3 is 2.000000
average rainfall for year 4 is 2.000000
average rainfall for year 5 is 3.000000

Note that only the rain amounts (not the labels) are stored in the input array (RAIN).

Business is becoming more and more competitive, and organisations have realised that purchasing and Supply Chain Management (SCM) are key factors in satisfying customers. Buyers and supply chain managers can contribute significantly to the organisation's profits. An organisation can spend as much as 50% of its sales revenue on purchasing parts, services, components and raw material. Therefore, efficient, mutually beneficial and constructive relationships with suppliers are very important to the organisation's short-term financial position and long-term competitive power.
1. The activities and objectives of different organisational buyers will dictate their purchasing needs and behavioural patterns with regard to purchases. Discuss the three types of organisational buyers. (10)
2. List and explain TEN criteria used to evaluate suppliers. (20)
3. Four critical factors have been identified for the successful implementation of a software-solution-driven SRM solution. Discuss these factors. (10)
4. Differentiate between constructive and competitive negotiation. (10)
5. Discuss the guidelines for maintaining positive supplier and customer relationships. (10)
Project Guidelines
 Your project should include a table of contents
 Text: Font: Arial or New Times Roman (12), spacing 1.5 lines
 All text must be justified at each margin
 The length of your answers to each question should be in line with mark allocations
 Your answers must include any theories, charts, tables or exhibits necessary to support your analysis and recommendations.
 Ensure that the readings are not merely reproduced in the project without original critical comments and views.
 References- At least 5 academic sources of reference must be used. (These include textbooks, journal articles and internet sources that are relevant to your field of study. Academic sources do not include Wikipedia and blogs). The MANCOSA study guide must not be used as a source of reference. You must include Reference list at the end of your project. Information quoted/paraphrased from sources listed in your Reference list must be referenced in-text. The Harvard system of referencing must be used.
 It is imperative that students proof read and edit their projects prior to submitting them. Projects must be free from errors and of a professional standard.

1. The process of reviewing the recording procedures for an accounting information system should include three areas. What are they?

2. Why is it necessary to introduce an AIS and how does recorded data contribute to problem-solving processes and to continuous improvement of products and service delivery? Discuss in 150–180 words.

Thank you

You are the manager of a local bank where three tellers provide services to customers. On​ average, each teller takes three minutes to serve a customer. Customers​ arrive, on​ average, at a rate of 43 per hour. Having recently received complaints from some customers that they waited a long time before being​ served, your boss asks you to evaluate the service system.​ Specifically, you must provide answers to the following​ questions:

a. What is the average utilization of the​ three-teller service​ system?

b. What is the probability that no customers are being served by a teller or are waiting in​ line?

c. What is the average number of customers waiting in​ line?

d. On​ average, how long does a customer wait in line before being​ served?

e. On​ average, how many customers would be at a​ teller's station and in​ line?

I would really appreciate it if all work is shown. Thank you for your time!

A large furniture company claims that 65% of all individuals who buy chairs from its stores choose wood chairs, 20% choose plastic chairs, and 15% choose metal chairs. To investigate this claim, researchers collected data from a random sample of the company's customers. The results were 305 wood, 121 plastic, and 74 metal. Are the data from the sample consistent with the company's claim? Conduct an appropriate statistical test at the 5% significance level to support your conclusion. Make sure to include parameters, check conditions, and show calculations before formulating a conclusion. (10 points)

Twenty-one mature flowers of a particular species were dissected, and the number of stamens and carpels present in each flower were counted.

(a) Is there sufficient evidence to claim a linear relationship between these two variables at α = .05?
(i) Find r. (Give your answer correct to three decimal places.)

(iii) State the appropriate conclusion.

New combinations of genetic material give rise to genetic variability in sexually reproducing organisms through

1. crossover events between nonsister homologous chromatids.
2. crossover events between sister chromatids.
3. egg and sperm genetic recombination from distinct individuals.
4. egg and sperm genetic recombination from one individual in which crossing over and independent assortment of homologues has occurred.
5. A, C, and D all contribute to genetic variability.
