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

Arthur Evans and the Palace of Knossos Archaeology has contributed greatly to our knowledge of past civilisation and in turn the general understanding of humanity’s progression through the ages. 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

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

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

Reactions and Equations Science Why should a magnesium ribbon be cleaned before burning in air? Answer Magnesium is very reactive metal. When stored it reacts with oxygen to form a layer magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper to remove this layer so that the underlying metal can be exposed into air. Question 2: Write the balanced equation for the following

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
