The differences to get fd 2 for each one. Recall and use the method of calculating the standard deviation of a set of discrete data. Select and use a working mean to simplify calculation. Newspaper articles. Step 6 Divide the total of the frequency multiplied by squares of the differences Teaching notes by the total of the frequencies.

Chapter 12 Statistics: Mean and standard deviation Learning objectives By the end of this chapter. Interpret the variation or spread of a data set in terms of its standard deviation. Calculate the mean deviation of a set of discrete data. Calculate the variance of a given data set. If the positive values of the deviations are taken. Mean and standard deviation.

This is then divided by This work is not really difficult if explained well. All these values are then added and divided by total of the frequencies. This gives the Students also do not make general mistakes.

We write So. If A is a proper subset of B. Modular arithmetic. Elements of a set are the members of the set. Union of sets The elements of the sets are put Division and Multiplication. Intersection of sets: The intersection of sets is the elements that these sets have in common. The LCM of 5 and 4 is New General Mathematics 1. So we have to write them with the same Glossary of terms denominator. Chapter 13 Revision of numerical processes Learning objectives By the end of this chapter.

Sets and their applications. The number of elements of a set. Revision of numerical processes Arithmetic and geometric progressions. Proportion and mixtures. Finite set is a set with a last element. Ratio and rate. Number bases. In one step: Infinite set is a set with an infinite number of 0. A is a subset that consists of at least one. Add and Subtract.

If A is a subset of B. Exercise 5d 4a. The example and the principle is where in the cycle reason is that its description cannot be one would end. Revision of numerical processes. The reason is that we can write: Ratios can. If 9 people take 21 days. The So. Proportion and mixtures Matrices Problems with mixtures and proportion could be difficult to solve and you should explain problems Refer to Chapter 8 of this book. Then the full Venn diagrams according to this value.

If Here we divided by 0 which is not defined. For Then you can explain why division by 0 is not example. Theory of logarithms. Calculations without logarithms. Teaching and learning materials So.

Evaluate means to determine the number value of is impossible. Give them a lot of guidance and or anti-logarithms. Then you do the following: See Chapter 1 of this book. This to practise this. You could remind them of the emphasise that it is essential that they write all following: Give them enough examples fractions. Revision of algebraic processes and Chapter 15 calculus Learning objectives By the end of this chapter.

This other form is simpler or from the inside brackets to the outside brackets. Teaching and learning materials This expression simply is a computing procedure Students: Algebraic fractions. The common factor that they represent any number and not objects.

Factorisation It is absolutely wrong to reason like this. This again is writing an algebraic factorised form of such an expression is a simpler expression in another form. Brackets are also removed in a different form. Revision of algebraic processes and calculus. The number k is in front of the middle term: The biggest for example. The equation. Revision of algebraic processes and calculus So if the value of one increases.

Emphasise that. This is called partial variation. Calculus Insist that they first factorise to avoid mistakes like See Chapter 10 of this book. To avoid this kind of mistake. You can make mistakes with signs. The last part not correct. L varies directly to F. When removing brackets by multiplication. Factorisation 42 Chapter The main mistake students make when simplifying fractions.

To avoid this mistake: We always write: Areas of difficulty and common mistakes Notice that the answer is correct. Change of the subject of the formula.

## Schaum's Outlines Discrete Mathematics

Quadratic equations. Equations and inequalities You always want the equation true. Word problems. Chapter 16 Equations and inequalities Learning objectives By the end of this chapter. Remove brackets by multiplication. If there are square roots. Clear all fractions by multiplying each materials and a calculator if possible.

Add a term with a sign opposite to the equation. Add all the like terms on both sides of Linear equations the equation. Add all the like terms on both sides of textbook. Linear equations. Teaching notes Step 2: Remove all brackets by multiplication.

Clear fractions by multiplying by the later experience problems when working with LCM of the denominators. Simultaneous linear equations. Add and subtract the same quantities undefined.

Linear inequalities. An equal sign does not work like magic to change all the signs to opposite signs on the Change the subject of the formula other side of the equal sign. If students do not understand this. Simultaneous linear and quadratic equations. They could of course have used the LCM If we have two linear equations in two variables of 2 and 9. Then the inequality sign is eliminate x.

Add like terms: Equations and inequalities. Remove the brackets by multiplication: It states that. Each one of these equations can be represented Quadratic equations by a straight-line graph. Multiply both sides of the formula by — Add equations. Step 1: Subtract 12 from both sides of the and so on. That way there could be no confusion. You only use the completion of the square Word problems to solve a quadratic equation when you are These problems are always difficult for the specifically asked to use this method. For Areas of difficulty and common mistakes example: If not.

Example 21 can for Step 4: If we solve for y. First try to factorise the equation then be bended to fit all the points on the curve.

Use a calculator to work out the answer. Stress work easier: Rewrite the equation in the standard to a letter symbol s. Emphasise that So.. If you cannot factorise the equation even if it Then a student can use a pencil and trace the does have factors. Emphasise that each term both Students make mistakes if they substitute the value sides of the equation must be multiplied by the of the variable they found into an equation to find LCM of the denominators.

Linear inequalities 2 4 Students tend to write the inequality shown in the sketch: The main reason for these errors is the fact that they do not use brackets for substitution. The the denominators.

You read it as: Each term is treated the value of the other variable. If this happens. Change the subject of the formula Let us say that they found that x. If they do not lie in a line. Quadratic graphs. Linear graphs. These steps can be followed: You then plot the points in the table on a a First plot the point Cartesian plane and draw a line through them.

Relations and functions. Sketch graphs. Always choose a negative number. Teaching and learning materials — On the y-axis all the x-coordinates are equal Students: Inverse functions 6.

Linear programming. The answer is: Natural numbers. If we use the point 1. Other line is solid. Remember for the change in x-values or the Step 3: Substitute any of the two given points horizontal change: Step 2: Now the equation so far is: Remember for the change in the y-values or Note that it does not matter which y-value the vertical change: Find the equation of the straight line that possibilities: Counting numbers.

Here is a summary of 2. To find c. Determine the gradient: Then the y-values decrease for the graphs called hyperbolic graphs. Look from left to right and keep the y-axis The functions in the textbook are examples of in mind. This x-value is in the a maximum. Explain to the class what a function is by telling This region is called the feasible region. Its value is also called the output value all Optimal postion the values that y have. Areas of difficulty and common mistakes The line in the middle below shows the optimal position of the objective function.

Its value is the input value all the values that x may have is 30 called the domain. Teach them to write their work out in their exercise books to x prevent mistakes. If it is. The function f very carefully. There are limit and so Statistics and probability. Grouped data. If one class interval is — Addition and multiplication laws of probability. Bar charts and pie charts. Chapter 18 Statistics and probability Learning objectives By the end of this chapter.

Teaching and learning materials Grouped data Students: In the table. The quantity of the other kinds of objects getting a six if you role the die. The probability that A and B happens So. When events are dependent. Clearly the first event will influence the number of choices you have for the second event. You then role a die number of objects is now 1 less and the number and get a six. When events are independent. Getting a tail does not reduce the number of If you take out one black ball and you do not choices for the second event.

Eating the first food item. This is called the sum Chapter 12 of this book. The number of white balls remains the same. Explain as follows: In your lunchbox you have 3 sandwiches and 2 apples. Statistics and probability You then choose another food item and eat it.

You choose a food item and eat it. Students can use a soft wire and bend it so that Mutually exclusive events it passes through all the plotted points. To help them you could give them summaries of the theorems and suggestions of the reasons they can use. Chapter 19 Geometry and vectors Learning objectives By the end of this chapter. D F C 54 Chapter Each position in a decimal number has a value that is a power of Denominator The part of the fraction that is written below the line.

It also tells you what kind of fraction it is. In this case, the kind of fraction is quarters. Direct proportion The relationship between quantities whose ratio remains constant. Directed numbers Positive and negative numbers are called directed numbers and are shown on a number line.

These numbers have a certain direction with respect to zero. Edge A line segment that joins two vertices of a solid. Elimination the process of solving a system of simultaneous equations by using various techniques to successively remove the variables. Expansion of an algebraic expression means that brackets are removed by multiplication Faces of a solid A flat planar surface that forms part of the boundary of the solid object; a threedimensional solid bounded exclusively by flat faces is a polyhedron.

Factorisation of an algebraic expression means that we write an algebraic expression as the product of its factors. Graphical method used to solve simultaneous linear equations means that the graphs of the equations are drawn. The solution is where the two graphs intersect cut each other.

Highest Common Factor HCF of a set of numbers is the highest factor that all those numbers have in common or the highest number that can divide into all the numbers in the set.

The HCF of 18, 24 and 30, for example, is 6. Inverse proportion The relationship between two variables in which their product is a constant. When one variable increases, the other decreases in proportion so that the product is unchanged. Inverse variation: Two quantities a and b vary inversely if, when a changes, then b changes by the same ratio inversely. Joint variation of three quantities x, y and z means that x and y are directly proportional, for example, and x and z are inversely proportional, for y y example.

## New General Mathematics Answers by J B Channon Mcleish Smith H C

Like terms contain identical letter symbols with the same exponents. For example, —3x2y3 and 5x2y3 are like terms but 3x2y3 and 3xy are not like terms. They are unlike terms. Lowest Common Multiple LCM of a set of numbers is the smallest multiple that a set of numbers have in common or the smallest number into which all the numbers of the set can divide without leaving a remainder.

The LCM of 18, 24 and 30, for example, is What is the total number of fifth graders represented on the graph?
