GROUP 1 ABSTRACT Analysis of Bharti airtel’s subscriber base was done using Time series analytical tools to develop predictive models. Different models linear‚ exponential were developed and December 2009 forecast was made using them. Our research revealed that subscriber growth is non linear thus best explained and predicted by exponential curve such as logistic curve. Introduction Tele-communication has evolved with time and in recent years with the growth in technology

Algebra‚ we have to go back over 3700 years‚ to the Babylonian civilization. Babylonians were particularly proficient algebraists and in the ancient civilizations they could solve quadratic problems (Kleiner‚ 2007). Records show that in 1600 B.C equations and symbols were not used in these problems‚ rather they were written out and solved verbally (Corry‚ 2005). Corry’s (2005) study found that a typical example of a problem made by the Babylonians was‚ Method of calculating a quantity‚ multiplied

The consultant should then run a multiple linear regression in linear and multiplicative forms based on the data provided by the company and report on the estimated result. They will have to evaluate the estimated demand equations both in linear and multiplicative forms‚ select the one‚ which can best describe the consumption. The consultant

Without archaeology‚ this knowledge and understanding would be extremely limited in its range of sources and evidence. Ancient civilisations underground provide an extensive range of remains and artefacts from which historians can draw accurate‚ informed conclusions about mortals who have long since turned

is 1 (one). Eigenvalues are introduced in the context of linear algebra or matrix theory. The introduction and development of the notation of matrix and system of linear algebra followed the development of determinant‚ which rose from the study of coefficient system of linear equations. Leibnitz‚ one of the founders of calculus used determinant in 1693 an Cramer presented his determinant - based formula system of solving linear equations (known as Cramer’s’ rule) in 1750. In 1848‚ James J Sylvester

1 DEFINITION OF LINEAR PROGRAMMING (LP) Linear programming (LP) is a mathematical technique used in finding the best possible allocation of resources to achieve the best outcome‚ which is maximising profit or minimising cost. However‚ it is only applicable where there is a linear relationship between the variables. For example‚ the linear relationships between hours of labour and output in a textiles factory means an increase or decrease in labour force has a direct impact on production‚ which
