CONCLUSION
Summary

This study made use of two mathematical methods that involves exponential functions. These methods are the Exponential Growth Model and the Logistic Growth Model. These methods are used in order to predict the total number of populaion and the growth rate of the country of Ghana, in the following years to come until the year 2050. Included in this study is the Mean Absolute Percentage Error (MAPE) which is used to solve the margin of error and determine the accuracy of both mathematical models utilized in this study. This theoretical dissertation allows the readers to learn about the practical application of mathematical models to real life situations, particularly in the field of demorgraphics. The forecast shall be determined
More importantly to the government officials, as having the an idea of the estimated population rate in the future can help them formulate strategies for the economic and social welfare of the country. Moreover, results of this research can also shed light to the students for they can use the mathematical models used in this study for similar researches and accordingly expand their knowledge on the lessons of math models and exponential functions. Furthermore, for the researches, this research may be used as a reference in doing relevant studies and improving the variables by including other vital factors and demographic variables that could yield a more accurate …show more content…
Meanwhile, the Logistic Growth Model showed results that Ghana will have a population of 341.2443 with a 5.13% growth rate. The MAPE value of Exponential Growth Model is 16.31% and the Logistic Growth Model is 95.21%. With these results, it can be observed that the Exponential Growth Model which shows a lower MAPE value has a more accurate outcome than the other model. By MAPE standards the results of Exponential Model were classified as a good forecast. This gives the implication that there is a high possibility that Ghana’s population will rise to 114.8207 in millions with a growth rate of 3.15%. However, with the margins of errors shown, it also gives the implication that these predictions are not 100% accurate. The inaccuracy is possibly caused by the limited scope of the study of the models used. Given that there are still a lot of factors that may affect the population of a certain country, and not all of these factors are included in the scope of the study. Some of these factors which should be taken into consideration to arrive at a more accurate result are the demographic variables of growth rate, death rate, life expectancy, and the rate of fertility. This raises the notion that this study still has a room for improvement and the factors as stated could be applied by further

In exponential & logarithmic functions we introduce and investigate the properties of exponential functions and Logarithmic functions. These functions are not algebraic; they belong to the class of transcendental functions. Exponential and logarithmic functions are used to model a variety of realworld phenomena: growth of populations of people, animals, and bacteria; radioactive decay; epidemics; absorption of light as it passes through air, water, or glass; magnitudes of sounds and earthquakes. We consider applications in these areas plus many more in the sections very important. As a part of our BBA course, we are required to submit a term paper for every subject each semester.

#### Population Growth

...Population Growth and Ecological Footprints The population size (N) of a species at any point in time (t) is determined by its size at (t-1), its per capita birth rate (b), its per capita death rate (d), and immigration and emigration. Each of these values is, in turn, affected by a huge suite of biotic and abiotic conditions. Human populations are governed by these same variables. In this laboratory, you will use models of population growth to understand how population growth is affected by changes in b and d, and why the actual values of b and d are important. You will also explore some dimensions of human impacts on the environment. A model is a mathematical description of how one thinks a system works. For a population growing at a constant rate, where b and d never change, an appropriate model for population growth is the exponential growth model: dN/dt = rN where r = b – d, assuming that immigration and emigration are negligible. This is a density-independent model since neither b nor d change with increasing population size. Conversely, the logistic model is a density-dependent model, where b and d change with changes in the population size: dN/dt = rN [(K-N)/K] where K = carrying capacity of the environment. In this lab you will use a simple Excel spreadsheet model to explore how population size (N) changes as b and d change under the two different growth models, exponential and logistic. The spreadsheets have areas that......

#### Sci 230 Week 9 Human Population Growth

...Human Population Growth SCI 230 August 16, 2013 Tammy Botten The term population growth refers to how the numbers of individuals in a population increases or decreases, with time. This growth is controlled by the rate of which new individuals are added to the population. Between the years 1800 and 1930 human population has doubled from one billion to two billion and then doubled again by the year 1975. This substantial growth in population has led to a decrease in population and biodiversity in many other species. The two types of population growth that can both be seen in human population growth are exponential growth and logistic growth. In population showing exponential growth the individual are not limited by food or disease. However in most real population both food and disease becomes important as condition becomes crowded. Logistic growth model is a more accurate representation of population growth because it takes into account that there are outside factors that may affect the growth. Logistic growth this is frequently used to model biological growth pattern where there’s an initial exponential growth period followed by leveling off as more as the population is infected so as the food supply or some other factors that limits further growths. Exponential growth means that some quality grows a fixed percentage rate form one year to the next. If the population has a constant birth rate......

...Question: How will you use the power of exponential technologies to bring about exponential impact? Answer: Embrace the idea of a Future that looks very different from Today. Before talking bigly about how the power of exponential technologies can bring about exponential impact, let’s take one step backward and see what the word “exponential” means to us first. The term “exponential” first popped up at 1965, it can be dated back to when Gordon Moore introduced the Moore’s law, which predicts the number of components per integrated circuit would double every year. With the establishment of Moore’s law, it left several insights to the world which are worth to mention: 1. It is predictable that the performance of technologies will double in very rapid way 2. The price of technologies will also decrease by half in very rapid pace. In terms of these prevailing conditions, we can see the exponential technology self-expands in its two traits to the world: Breadth and Depth. So how could these two expansions traditionally make exponential impacts in century? Take camera as an example, it has been evolved from the world’s first digital camera – Kodak Digital Camera at 1975 which cannot take video-taped to the nowadays digital single-lens reflex camera at 2016 which can offer superb image quality and video recording at 4K resolution. In terms of performance, instead of using camera to capture best moments every day, people now use camera: To show the rest of the “fan......

Forecast types   1. Meaning of forecasting Forecast is a likely, scientifically well-grounded opinion about the possible state of the events, objects or processes in the future. Forecasting is a process of making statements about events whose actual outcomes (typically) have not yet been observed. Forecasting is a process of predicting or estimating the future based on past and present data. Economic Forecasting is a process of making forecasts based on analysis of past trends and regularities of the economic processes. Economic forecasts can be carried out at a high level of aggregation – for example for GDP, inflation, unemployment or the fiscal deficit – or at a more disaggregated level, for specific sectors of the economy or even specific companies. Economic forecasting provides information about the potential future events and their consequences for the organization. It may not reduce the complications and uncertainty of the future. However, it increases the confidence of the management to make important decisions.   Economic forecasting includes the following steps: 1. Identifying items to be forecast. The items of socio-economic forecasting are the economic processes (for example, inflation, demand, supply), any indicator describing the company activity (for......

#### Population Dynamics

...Question 1. What is the effect of changing lambda (λ) in the discrete model, and r in the continuous model? What is the effect of changing N0 in both models? (2 marks) When in discrete mode, a change in lambda (λ) will change the growth rate of the species. If λ increases, so does the growth rate and if λ decreases, as will the growth rate. However, the growth rate only increases if the number is above 1. 1 itself indicates no growth and below one is negative growth. The same principle applies to r. However, as apposed to 1, 0 is no growth while below 0 and above 0 is negative and positive growth, respectfully. Figure 1 and 2 show a stable, increasing and decreasing population for both continuous and discrete growth. Question 2. What are the differences between the discrete and continuous models of population growth? (2 marks) Discrete growth shows a type of growth in populations that have seasonal breeding seasons (Alstad, 2001). This means the percentage increase can be added after the season to the group. Continuous growth means that the growth of the population is continuously growing without seasons and has overlapping generations. An example of discrete growth is figure 1 and continuous growth in figure 2.

#### Greaves Brewery Case Analysis

...manager for the company, Alex Benson, is uncertain about how many bottles to order from the company’s German glass supplier. His decision is complicated by the possibility of a new bottle design being introduced that would compromise his existing inventory of bottles. Additionally, he is faced with storage limitations and erratic sales, all of which are impacting his decision. He is also concerned about over ordering to avoid issues from an off year, impact from government tax, tourism, and growth of exports. Assignment Question How many bottles should Alex Benson, purchasing manager of Greaves Brewery, order to support his company’s sales for the upcoming year 2004? Case Analysis Greaves Brewery was founded in 1924 by John Greaves in the Caribbean island of Trinidad. In addition to being a favorite among the local population, the beer was also popular with tourists which contributed to the export of the beer some years later. The brewery experienced positive growth between 1999 and 2003, which was attributed to peak sales periods during Carnival, Easter, Christmas and Independence. Throughout the years, the government of Trinidad introduced a number of excise taxes on beer. This negatively impacted sales at Greaves Brewery. Along with normal business challenges and other factors such as number of tourists and U.S. sales, determining the full impact of the taxes on the market made it more challenging for the company to forecast sales. ......

#### Associative and Time Series Forecasting

...Forecasting Models: Associative and Time Series Forecasting involves using past data to generate a number, set of numbers, or scenario that corresponds to a future occurrence. It is absolutely essential to short-range and long-range planning. Time Series and Associative models are both quantitative forecast techniques are more objective than qualitative techniques such as the Delphi Technique and market research. Time Series Models Based on the assumption that history will repeat itself, there will be identifiable patterns of behaviour that can be used to predict future behaviour. This model is useful when you have a short time requirement (eg days) to analyse products in their growth stages to predict short-term outcomes. To use this model you look at several historical periods and choose a method that minimises a chosen measure of error. Then use that method to predict the future. To do this you use detailed data by SKU's (Stock Keeping Units) which are readily available. In TSM there may be identifiable underlying behaviours to identify as well as the causes of that behaviour. The data may show causal patterns that appear to repeat themselves – the trick is to determine which are true patterns that can be used for analysis and which are merely random variations. The patterns you look for include: Trends – long term movements in either direction Cycles - wavelike variations lasting more than a year usually tied to economic or political......
