...P2 There are many nutrients that are required for a balanced, healthy diet, five of which are: carbohydrates, proteins, lipids, vitamins and minerals. Carbohydrates: Carbohydrates is a micronutrient, alongside fat and protein which all provide us with energy quickly. A carbohydrate is a sugar and is composed of hydrogen, carbon and oxygen. It helps digestion and provides energy. Carbohydrates are divided into 3 groups: starch, fibre and sugar, which all help digestion. Protein: Protein is found in foods such as eggs, meat, fish and cheese. A source of protein is formed when a group of amino acids are joined together in chains. Each chain is called a polypeptide, eight of them come from the different foods mentioned previously. In terms of its...

If the new price is p= 0.60, Then the break even volume will decrease. We don’t need to sell as much units as before to break even. Proof: V= 30000/ (0.6- 0.16) V= 68181.81 units 4. If we increase advertising, that means CF increases, then the Break even volume will increase, because the cost of the production increased.

...Price Elasticity of Demand A. Definition Price Elasticity of Demand is a measure of how much the quantity demanded of good responds to a change in the price of that good. B. Formula [pic] this value is normally negative. Notes: • Since the demand curve is downward sloping the above fraction will have a negative value. To change the negative value into a positive value the absolute value is taken. • Elasticity is different from slope. Slope is measured by ∆QD/∆P C. Five Classifications 1. Perfectly inelastic demand does not change [pic] % change in QD = 0 2. Inelastic demand little change [pic] % change in QD < % change in P 3. Unit elastic demand [pic] % change in QD = % change in P The only way it can be equal to one is if its curve linear. 4. Elastic demand [pic] % change in QD > % change in P 5.

Overhead is charged weekly at the rate of €1838 and 0.75 times direct cost. Week | 1 | 2 | 3 | 4 | Output | 636 | 576 | 624 | 644 | Workers | 12 | 11 | 11 | 9 | Material (meter) | 4125 | 3675 | 3930 | 4035 | A. Briefly explain the concept of productivity? Productivity Productivity is a measure of the rate at which outputs of goods and services are produced per unit of input (labor, capital, raw materials, etc.). It is calculated as the ratio of the amount of outputs produced to some measure of the amount of input used. Productivity = Quantity of goods and services produced Amount of resources used As the equation indicates, there are two variables in measuring productivity- the amount of production and amount of resources used. Productivity varies with the amount of production relative to the amount of resources used. Productivity can be increased in several ways, which Are given below here- 1. Increase production using the same or a smaller amount of resources. 2. Reduce the amount of resources used while keeping the same production or increasing it. 3. Allow the amount of resources used to increase c production increases more. 4. Allow production to decrease as long as...

...Demand and Supply: The Basics 21 FUNDAMENTALS OF ECONOMICS FOR BUSINESS - (Second Edition) © World Scientific Publishing Co. Pte. Ltd. http://www.worldscibooks.com/economics/6794.html Chapter 2 Introduction The most basic, and in many ways the most lasting, lesson to be learnt from “Economics 101” relates to the fundamental concepts of demand and supply and their interaction. These are usually presented in a simple graphical format involving demand and supply “curves”. The word is in quotes because in this chapter, for simplicity, we will actually assume only straightline relationships between price and quantities demanded and supplied. The main issue that is important in reality is the direction of the relationship between prices and quantities. Will a reduction in price lead to an increase in the quantity demanded of any particular product or service? Will an increase in price lead to an increase in supply? And so on. The principal technical tools for analyzing demand and supply conditions in particular markets, then, are the demand and supply schedules or curves. The demand curve shows an estimate or conjecture about the relationship between the price of any particular product or service and the quantity of that product that will be demanded by consumers. It is usually assumed to slope downward, in the general case, for most products and services. In other words, the lower the price of the item, the greater the quantity of it that will be demanded. Technically, this...

...Chapter 1 Microeconomics of Consumer Theory The two broad categories of decision-makers in an economy are consumers and firms. Each individual in each of these groups makes its decisions in order to achieve some goal – a consumer seeks to maximize some measure of satisfaction from his consumption decisions while a firm seeks to maximize its profits. We first consider the microeconomics of consumer theory and will later turn to a consideration of firms. The two theoretical tools of consumer theory are utility functions and budget constraints. Out of the interaction of a utility function and a budget constraint emerge the choices that a consumer makes. Utility Theory A utility function describes the level of “satisfaction” or “happiness” that a consumer obtains from consuming various goods. A utility function can have any number of arguments, each of which affects the consumer's overall satisfaction level. But it is only when we consider more than one argument can we consider the trade-offs that a consumer faces when making consumption decisions. The nature of these trade-offs can be illustrated with a utility function of two arguments, but is completely generalizable to the case of any arbitrary number of arguments.1 An advantage of considering the case of just two goods is that we can analyze it graphically because, recall, graphing a function of two arguments requires three dimensions, graphing a function of three arguments requires four dimensions, and, in general, graphing...

...customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customers per minute. a) What is the mean or expected number of customers that will arrive in a five-minute period? The expected number is of 0.4*5 = 2 customer is a five-minute period. b) Assume that the Poisson probability distribution can be used to describe the arrival process. Use the arrival rate in part (a) and compute the probabilities that exactly 0, 1, 2, and 3 customers will arrive during a five-minute period. The probabilities of the described scenarios are as follows: P0=20e-20! P0=0.135335283 P1=21e-21! P1=0.270670566 P2=22e-22! P2=0.270670566 P3=23e-23! P3=0.180447044 c) Delays are expected if more than three customers arrive during any five-minute period. What is the probability that delays will occur? This probability can be expressed as the probability of more than 3 customers arriving during the five-minute period, which can be computed as following: P(x > 3) = 1 – P(x ≤ 3) P (x > 3) = 1 – 0.85712346 P(x > 3) = 0.14287654 Thus, there is a 14, 29% probability of expected delays in five-minute period.

...CPU SCHEDULINGCPU scheduling in UNIX is designed to benefit interactive processes. Processes are given small CPU time slices by a priority algorithm that reduces to round-robin scheduling for CPU-bound jobs.The scheduler on UNIX system belongs to the general class of operating system schedulers known as round robin with multilevel feedback which means that the kernel allocates the CPU time to a process for small time slice, preempts a process that exceeds its time slice and feed it back into one of several priority queues. A process may need much iteration through the "feedback loop" before it finishes. When kernel does a context switch and restores the context of a process. The process resumes execution from the point where it had been suspended.Each process table entry contains a priority field. There is a process table for each process which contains a priority field for process scheduling. The priority of a process is lower if they have recently used the CPU and vice versa.The more CPU time a process accumulates, the lower (more positive) its priority becomes, and vice versa, so there is negative feedback in CPU scheduling and it is difficult for a single process to take all the CPU time. Process aging is employed to prevent starvation.Older UNIX systems used a 1-second quantum for the round- robin scheduling. 4.33SD reschedules processes every 0.1 second and recomputed priorities every second. The round-robin scheduling is accomplished by the -time-out mechanism, which tells...
