Mathematics is all around the young child from day one. For example certain matters like “How old are you?” “You were born on the 2nd” “I have 2 brothers”. Number itself cannot be defined and understand of number grows from experience with real objects but eventually they become abstract ideas. It is one of the most abstract concepts that the human mind has encountered. No physical aspects of objects can ever suggest the idea of number. The ability to count‚ to compute‚ and to use numerical relationships

Ratio and Proportion • If 2 numbers are in ratio a: b then consider them as ax and bx (where x is the proportionality constant) and apply ax and bx in the given condition of the problem to proceed for answer • Ratio can be applied between 2 units if and only if the same physical quantity is compared • Length : length is correct • Length : density is wrong • Ratio can be made only after the units are compared in the same unit • If two lengths are 1 mile and 1 km respectively then ratio

objectives of measure of central tendency are To reduce data in a single value. To make easy comparisons between data. There are different types of averages; each has its own business applications. 1. Arithmetic Mean 2. Median 3. Mode 4. Geometric Mean 5. Harmonic Mean 1.1 Arithmetic Mean 1.1.1 Definition Most important measure of location is the mean or average value‚ for a variable. The mean provides a measure of central location for the data. If the data are for a sample‚ the mean is

CHAPTER ONE 1.1 INTRODUCTION The at-grade intersection form over 90% of the road network in the nation’s highway system. It plays an important role in the road network‚ where traffic flows in different directions converge. It is imperative that where two or more roads meet‚ there is always a need to make a provision for intersections design in other to channel traffic into different streams. Due to several interaction that takes place between road users and traffic control systems‚ capacity of

proportional to the function’s current value. Exponential decay occurs in the same way when the growth rate is negative. In the case of a discrete domain of definition with equal intervals it is also called geometric growth or geometric decay (the function values form a geometric progression). The exponential growth model is also known as the Malthusian growth model. The formula for exponential growth of a variable x at the (positive or negative) growth rate r‚ as time t goes on in discrete intervals

Mathematics (Algebra and Geometry) Introduction Mathematics is the language of all sciences. The subject at the secondary level has great importance in a progressive country like India as it develops various living skill. It is important to note that the subject itself has a separate identity in the life of a man. The challenges due to the tremendous growth in the population‚ globalization‚ pollution‚ competition between countries‚ natural disasters emphasise the need to develop the curriculum

with common knowledge of the third and fourth dimensions. Dalí painted a geometric figure known as a hypercube‚ which represents a tesseract. In simplistic terms‚ a tesseract is symbolic of the fourth dimension otherwise known as spacetime. The hypercube is significant because its overarching purpose is to create an optimistic outlook on life‚ since one’s life is theoretically encompassed within the tesseract. Another geometric formation looming in the painting is the gloomy checkered floor. The two
