Essay on China Population Trends Practice Math Ia

Population Trends in China The goal of this mathematical study is to explore the different functions that best model the population of China from the years 1950 to 1995. Year | 1950 | 1955 | 1960 | 1965 | 1970 | 1975 | 1980 | 1985 | 1990 | 1995 | Population in Millions | 554.8 | 609.0 | 657.5 | 729.2 | 830.7 | 927.8 | 998.9 | 1070.0 | 1155.3 | 1220.5 | Using the Chinese population data from 1950 to 1995, let us construct a graph using technology. Before graphing the data though, we must first determine the relevant variables, which are, the year and the population (in millions) of each coinciding year. The parameters are strictly confined to the data for the years 1950 and 1995 in the sense that the data cannot fall below the†¦show more content†¦Even looking at the data table for the function, we see that the data is very close to the original set of data. We know that in polynomial functions, the independent and dependent variables are directly related to each other. In this study the pattern of the original data indicates a continuous gradual incline, so as the years increase so will the population. The logistic function is different in the sense that while it will continue to increase, after awhile it will not increase as much and will begin to slow down until it stops increasing and levels off. The graphs below are to aid in the understanding of the concept. We are next given a set of data on the population trends in China from the 2008 World Economic Outlook published from the International Monetary Fund (IMF) Year | 1983 | 1992 | 1997 | 2000 | 2003 | 2005 | 2008 | New Population in Millions | 1030.1 | 1171.7 | 1236.3 | 1267.4 | 1292.3 | 1307.6 | 1327.7 | We will start with the polynomial function and again choose three different points for the above data. So we will get: y= ax2 + bx +c 1030.1=a (19832) + b (1983) + c 1267.4=a (20002) + b (2000) + c 1327.7=a (20082) + b (2008) + c We can call the y-values matrix ‘B’ or [B]Show MoreRelatedAnnual Report Rolls-Royce78484 Words   |  314 Pagesbe identified by the fact that they do not relate only to historical or current facts.
