set_powerpoint1.ppt
This document describes the card game Set and explores using it to model geometric concepts. It contains the following key points:
1. Set is a card game where the goal is to find sets of 3 cards that are either all the same or all different in each attribute (number, color, shading, shape).
2. The game can be used to model basic geometry concepts like points, lines, and planes. A card is a point, a set of 3 cards is a line, and 9 cards arranged in a specific pattern form a plane.
3. More complex geometric concepts like hyperplanes can also be modeled using sets of cards. A hyperplane is formed from 4 non-coplanar points
Lecture Week 17 which hleps in study for logic and
This document summarizes a lecture on logic and problem solving that covered:
1. The basic principle of counting, permutations, and combinations. Permutations involve order while combinations do not.
2. Examples were given to demonstrate the fundamental counting principle and formulas for permutations and combinations.
3. Permutations and combinations with repetition were also discussed along with circular permutations.
4. Exercises were provided to practice applying the concepts through problems involving counting arrangements of letters, books, team selections from groups, and card selections.
Probability
This document contains 10 math word problems about probability. The problems involve calculating probabilities of events occurring based on given sample spaces and conditions. They also involve determining expected values and using probability to solve for unknown quantities.
9.2 Tree Diagram
The document discusses using tree diagrams to count outcomes and find probabilities. It provides examples such as Sarah choosing an outfit from different shirt and skirt options, a matching game with spinners, tossing coins, picking marbles from bags, and making lunch combinations. Students are asked to work through examples using tree diagrams and consider if shortcuts exist for finding probabilities.
Advanced business mathematics and statistics for entrepreneurs
The document provides explanations and formulas for various statistical and mathematical concepts related to business such as permutation, combination, probability, and time value of money. Formulas are given for permutation, combination, present value, future value, effective interest rate, and examples are provided to demonstrate how to apply the formulas to calculate values.
Counting
This document discusses counting possibilities and provides examples to illustrate different counting principles:
1) Counting possibilities can sometimes be easy, like counting fingers, but other times require principles, as shown in harder questions about numbers and geometric shapes.
2) An example activity demonstrates counting the possibilities of choosing 3 students out of 5 for competitions. The number of possibilities is 60, calculated using a factorial arrangement formula.
3) Permutations refer to arrangements where order matters, and the document explains the permutation formula using n elements chosen from n total elements. Possibilities allowing repetition are called p-lists and follow the formula np.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems
9
Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

- 4. In a party, each person has to give a handshake to the other person only once. If the total number of handshakes exchanged in the party is 435, then find the number of persons in the party? Ans : Handshake ( selecting 2 hands at a time) = = 435 ( ) = 435 n = 30 Number of persons = 30 1. number of persons in the party = 30
- 5. In how many ways can u invite atleast one of your 8 friends to a party?2. + + ….. We know that + + + + ….. X=1 , n =8
- 6. How many diagonals are there in an octagon?3. Ans : To draw a polygon with n sides, we require n non-collinear points. The total number of line segments that can be drawn using n non-collinear points is given by Number of diagonals = - n ( n = number of sides ) In the given question, N = 8 => Number of diagonals = - 8 Number of diagonals = 20
- 7. How many rectangles are there in a chessboard?4. Ans : If a set of m parallel lines intersect with another set of n parallel lines then the total number of parallelograms formed are Total number of parallelograms formed in chess board = = 1296 Total number of squares in a chessboard = 204 Total number of rectangles = 1296 – 204 = 1092. Total number of rectangles = 1092
- 8. Out of 5 boys and 4 girls, a team of 4 should be selected. In how many ways can u select the team, such that there is atleast one girl in the team? 5. Ans : 1G, 3B ; 2G, 2B ; 3G, 1B ; 4G or ( any 4 – 4B ) Number of ways = + + + = 121 OR Number of ways = = 121 Number of ways = 121
