The NBA championship is the main basketball championship in the United States. The championship is divided into two sections, the West and East coast conferences, where teams from both sections compete to become the ultimate champions. From research and simple logic, it can be deduced that the team with the least losses in the season eventually go on to win the championship in the playoffs. However, the number of losses, or wins, that a team has does not solely determine the win, since the final games determine the eventual winner. However, the record that a team has indicates the probability of ...

A. What is similarities and differences do you see between functions and linear equations studied in Ch. 3?
Functions and linear equations have elements which create straight lines when plotted on the graph. Both linear equation and a function are polynomial to the first degree. A linear equation and function have variables that are paired and separated by comma in a bracket. The variables are normally in form of x and y with each having one value. A linear equation is an algebraic expression having two variables with similar value while a function has only one variable. The major use of a function ...
1) Describe how to formulate and test hypothesis about a population mean and/or a population.
A hypothesis essentially refers to the prediction of the expected outcome of a research process. When one intends to research a particular subject, event or outcome, he ought to state his expected outcome. There are two types of hypotheses; null and alternate hypotheses. The null hypothesis refers to what the researcher is trying to nullify, disapprove or reject. In testing the hypothesis, the researcher attempts to prove the hypothesis either wrong or right. In hypothesis testing, the researcher needs to first state both the null and alternate hypotheses. The researcher then needs develops an analysis plan which describes how to use ...
1. Solving linear inequalities and linear equations is very similar. However, there is some discrepancy. Inequality sign changes into opposite when two parts of inequality are multiplied by a negative number. For example,, but. Besides, the solution of a linear equation is a single point while the solution of linear inequality is intervals. For example, we solve linear equation and linear inequality.

Spectrophotometry refers to a method that is employed in the determination of the amount of light that is absorbed by a chemical substance. In chemistry, the term spectrophotometry refers to the determination of the reflection or transmission characteristics quantitatively material through a function of wavelength (NIST, 2012). The spectrophotometry analysis is carried out through the light intensity determination as a beam of light passes through a tube containing the sample solution. The process of analyzing solution concentration using spectrophotometer utilizes the fact that light possesses a dual nature. This is where the light may exist either as particle or as a wave (Keller, 2003).

Enzymes are protein molecules that act as catalysts to break down substances living thing need to sustain life. Most chemical reactions are too lengthy to do this on their own; even in the cases of relatively thermodynamically favored reactions like that of the oxidation of a sugar. An example of this is the oxidation of glucose to produce water, carbon dioxide and energy. Glucose on its own can remain exposed to air for years without any appreciable oxidation. Nevertheless, it is one of the substances most quickly broken down and absorbed in the human body due to the digestive system’ ...

- What are the two types of statistics? (5pts.)
The two types of statistics are descriptive and inferential. In descriptive statistics, the data of a population is summarized graphically or numerically through derivation of statistics related to central tendency and dispersion around the same. The shape and nature of distribution is also used in descriptive statistics.
In inferential statistics, the parameters of a population are inferred according to sample statistics. This involves the estimation of statistics of a group allowing for approximation of information data relating to the entire population. In this type of statistics, modeling are used to generate mathematical ...
Assets are usually owned by the business. Businesses use these assets in order to generate revenue by selling goods and services. Assets are both tangible and intangible. Normally tangible assets include cash in hand, furniture and fixture, plant, machinery etc. while intangible assets include goodwill of business, trademark or patent etc. (O'Keefe, 2010)
According to GAAP, either the owner of the business owned the assets of business or subject to the claims of creditors. Creditors are those persons who have given loans to another person or businesses. Such loans or credits are called liabilities. Such portions of ...
Q1. Describe the three main layers of the Sun’s interior.
The three main layers of the Sun’s interior are the core, the radiative envelope and the connective envelope.
The core is the center of the Sun, with a density of 150 g/cc and a temperature of 15 million K. This is the region where high energy fusion reactions take place and energy is produced. The energy produced is mainly in the form neutrino and gamma rays, which are actually high energy protons which travel several light years and supply energy to the Earth and other planets. The energy produced in the core then radiates outwards through the radiative zone. The ...
A dependent variable can be defined as the factor that changes resulting from changes in the independent variable (Geweke, 2010, p. 310). For example, in a controlled experiment, this can be described as what tends to be tested for result (Hendry, 2009, p. 60). In this assignment, I decided to analyze the number of mergers and acquisitions (M&A) in Britain, among companies in the United Kingdom between 1969 and 2011. I find the variable of interest since it exhibits considerable variability and would, therefore, be challenging to model. The variable (Mergers & Acquisitions) exhibits high year to year variability, ...
1. Describe the role probability information plays in the decision-making process.
Decision making involves selecting best alternative based on personal values and preferences. Therefore, a decision can only be made from some possible alternatives provided. The decision arrived is taken to be rational if it was the one which had the highest probability of success and it serves the decision makers life goals, desires, values and lifestyle. Likewise, in business organization the managers strive to make decisions which can propel an organization towards achieving its goals. They always consider the probability of an event occurring or even not occurring, and then they settle on one of the possible alternatives (McClave, Benson, ...

The line of best fit indicates a positive linear relationship between the staff cost and sales. The convergence of the points towards the mean further shows little variation in the various factors/variables that determines the staff cost in the company. There is little erroneous data indicated by a single outlier at the upper right corner of the chart. The coefficient of determination further a test to a god fit to the data ...
Improvement of quality by elimination/ variation of a process
Quality in a process measures its excellence and its freedom from deficiencies. The general process of quality improvement starts with recognition that quality deteriorates due to wear and time (Adams and Carroll 36). The other step involves stabilizing and understanding the process. The next process is designing products as robust from their earliest stages to design phases. This is achieved by making a product insensitive to the natural environment (Adams and Carroll). The Taguchi approach can be applied for optimizing mature projects and processes. To obtain the best output, an empirical equation of the system is applied. Input factors are set ...

Drinking was also found as a contributing factor to asthma. Heavy drinkers are less prone to asthma than non-drinkers. Also, it was established that there is not enough evidence that smoking causes asthma. It was also found that asthma is not biased ...
This study focuses on how education and the level of unemployment are related. In our daily activities, education has proved to be inevitable. Most of the knowledge acquired by people comes as a result of having education. Education is known to solve many problems in the world. That is one of the major reasons why it is treasured as a basic commodity in our daily activities. Education may be in two forms: formal and informal. These two types are distinct since they involve different methods of teaching. Formal education may involve going to modern schools in order to attain quality education. ...
John Maynard Keynes (5th June 1883-21st April 1946) was one of the founders of modern macroeconomics. He was a British Economist, and he was in the Keynesian economics school of thought. His main contribution towards macro economics was the formulation of the Theory of Employment. His theory of employment opposed what the Classical Economists proposed.
In the theory of Employment, Keynes argues that the main cause for unemployment was insufficient expenditure in investment. Keynes argues that unemployment is as a result of rigidity in wages. The low demand for output and workers to perform a job causes involuntary unemployment. The classical economist ...

Kinetic theory of matter tries to explain all molecules in terms of motion. The theory posits that every substance consists of many small particles referred to as molecules. Substances in this case are called matter and are in three forms; solids, liquids, and gases. Solids have molecules that are closer to each other by intermolecular forces. Liquids on the other hand have molecules slightly far apart with gases the furthest apart. Furthermore, according to this theory all the molecules are in constant random motion referred to as Brownian motion (Chang, 2004).
The study of heat relates to kinetic theory ...
