Weighted mean is referred as the same as that of arithmetic mean. Where as each of the data is contributed uniformly with the weighed value. Incase all the weighted values are equal, and then the weighed mean is equal to the arithmetic mean. Weighted mean generally behaves similar fashion to the arithmetic mean. The term weighted average can also be known as weighted arithmetic mean or weighted harmonic mean.
First calculate the sum for allocated weighted value & observed value.
Second calculate the sum for all the observed values.
Third make the division for the above 2 calculated values.
sin90°,sinα = y/x, 90° angle is known as a right angle y =1 r= 1 x = 0
sin 90° = y/r = 1/1 = 1
By the meaning in trigonometry, sin x = opposite/hypotenuse
Where “x” indicates any degree.In this case the x is 900 that are we need to get the value of sin ninety degrees. Hence we need to draw the right angled triangle.
·A right angled triangle opposite side’s length is equal to hypotenuse side length.
·the sine of the angle = The length of the opposite side is divided by Hypotenuse length
Finally sin 900 = the length of the ‘hypotenuse side’is divided by The length of the ‘hypotenuse side’
= 1.
·The normal outline of sin can be mention as sin X = cos(90-X), hence sin 90 = cos (90-90) = cos 0 =1

-->With ever increasing class sizes, & the decreasing attention spans of student, it is no wonder that students are learning less from the classrooms. Pair this with the ever increasing standards of the local education system & this spells trouble. I believe that private tuition is another forum for learners to learn & have their questions answered, in face of some inadequacies of the current education system in place. smart tuition online is no longer a luxury, but a necessity to do well in today's competitive arena. smart tuition online is a fact that students need tuition in order to keep up with their peers and excel. A qualified private tutor will use a variety of tutoring methods to work through difficult areas of a subject so that the core concepts remain long after the session is finished. In this way the children can, more often than not, recall facts & figures during tests, quizzes & exams & this can only lead to better marks
Therefore smart tuition online believe in providing quality tutors that will help your children excel & compete with his/her peers. Here at smart tuition online, our tutors are dedicated and committed in providing the best for your students. Smart tuition online agencies play an important part in the education process. Smart tuition online is a wise investment in a child's future. Any parents, who have the means, would want the best tutor or train to help build a solid foundation for their children's future career!
When many of us turn towards smart tuition online for help, where teachers are more motivated, both due to the fact that you’re paying them directly, & also if it is home tuition, full attention will be given to student & student’s work. No favoritism, ostracism of any sort, & as someone who had given private tuition, the success of students will only add to your own satisfaction.
-->Simplified radical form is an expression which is under the symbol square root. The expression contains fraction, addition, multiplication, subtraction. The simplified radical form is to simplify the specified expression in very simplified form. The simplified radical form includes the symbol square root in the numerator but not in the denominator.
A radical is also in simplest form only when the radicand is not a fraction. 49 is a sq factor of 98, so the simplified radical would be seven times the square root of two or seven on the square root of 2. All exponents in the radicand should be less than the index. Any exponents in the radicand may have no factors in common with the index. No fractions appear under a radical. No radicals appear in the denominator of a fraction
The most commonly used system of numerals is called as Hindu-Arabic numerals & 2 great Indian mathematicians are credited with developing them. Aryabhata & Brahmagupta.
A numeral system is a writing system for expressing numbers, which is a mathematical notation for representing numbers of a given set, using graphemes or symbols in a consistent manner. Numeral most commonly can be seen as the context that allows the numerals "11" to be interpreted as the binary symbol for 3, the decimal symbol for eleven, or a symbol for other numbers in different bases.
Decimal numeral system is the mostly common used numeral system.
-->Elimination math means a set of equations dealt with at the same time also called as simultaneous equations, 2 linear equations with 2 variables are the common ones which can be solved using the following process .
1 . Elimination process 2 . Substitution process 3 .Graphing process
Elimination process is the process of eliminating 1 of the variables in a system of equations using addition or subtraction in conjunction with multiplication or division & solving the system of equations
Boolean simplifier expression is not unique always. The simplifier for the number of variables & the number of terms which contained should be identical, & the terms themselves may be different when there is not a unique answer.
The different kinds of operators are equal to operator (=), comparison operator (<,>,<=,>=, =) & logical operator (and ,or, not).
Logical operators of the operations in math can be combined with comparison operators to produce more complex Boolean expression. The best example illustrates below the use of Boolean expressions with comparison operators in conjunction with a logical operator.
-->There are seven pens in a box.2 are black color pen.3 are blue color pen.2 are red color pen. What is the probability that a black pen will be picked? Number of ways is occurs: 2(there are 2 black color pen)
Total number of outcomes: 7(there are 7 pens in total)
So the probability is 2/7=0.28
-->In the primary grades children are developing number sense & their concept of numbers by using math times table chart & how number system works this can be challenging for even the brightest student, as mathematics is very conceptual & students are not always developmentally ready for the skills as they are introduced Multiplying the values 25 * 16

Let us learn about linear equations with two variables
-->x = 1, y = 1 is a solution of 2x + 3y = 5 2(1) + 3(1) = 5 x = -2, y = 3 is also a solution of 2x + 3y = 5 2(-2) + 3(3) = 5 -4 + 9 = 5 You can find many more solutions for 2x + 3y = 5
A system of linear equations is 2 or more linear equations that are being solved concurrently.
A linear equation in 2 variables is of the form ax + by = c, Where a ≠ 0, b ≠ 0
Linear equations in 2 Variables Example
2x + 3y = 5, x - 2y = 6, -6x + y =8 A pair of values of y & x that satisfy a given linear equation in 2 variables is said to be its solution.
-->Certain geometric diagrams can be divided into 2 identical parts by a line passing through the diagrams. These diagrams are said to be symmetrical about that line, & the lines are called the lines of symmetry or axis of symmetry. Lines of symmetry are also said to be as mirror lines, because the part of the diagrams on 1 side of the line looks like a mirror image of the part of the diagrams on the other side of the line. Lines of symmetry of diagrams are also referred to as the axis of symmetry, since on rotating the diagrams about that line by 180 degrees 1 half is the reflection of the other half. The "Line of Symmetry" is the imaginary line where you could fold the image & have both halves match exactly. Line of symmetry is a line that divides diagrams into 2 congruent parts, each of which is the mirror image of the other. When the diagrams having a line of symmetry are folded along the line of symmetry, the 2 parts should coincide.
The graphical method for valuating or estimating the parameters of accelerated life data includes generating 2 types of plots. 1st, the life data at each individual stress level are plotted on a probability paper apposite (appropriate) to the assumed life distribution i.e. Weibull, exponential, or lognormal. The parameters of the distribution at every stress level are then valuated from the plot. Once these parameters have been valuated at each stress level, the 2nd plot is created on a paper that linearizes the assumed life-stress relationship i.e. Arrhenius, inverse power law, etc.. The parameters of the life-stress relationship are then valuated from the 2nd plot. The life distribution & life-stress relationship are then combined to provide a single model that describes the accelerated life data.

-->Solve the equation for x, 2(6x - 68) = 69. Solution:
2(6x - 68) = 69 (multiply 6 within the parenthesis)
(2 6x) – (2 68) = 69
12x – 136 = 69 add both sides by 136
12x - 136 + 136 = 69 + 136
12x = 205 divide both side by 12
12x/12 = 205/12
x = 17.08

-->The goal of every geometry learner is to be able to eventually put what she or he has learned to use by writing geometric proofs. Throughout the Spark Notes under Geometry one & two we have gained the knowledge to know what is & isn't true of a given geometric figure & why. In this Blog, we'll develop the skills to show what learners know in formal, 2-column geometric proofs. Using geometric proofs systematically, deductive reasoning, lead a reader step-by-step from the premises of a proof to the conclusion--what may have been suspected but weren’t known for sure. In the following article we'll study the form of a geometric proof, as well as different techniques for proving things geometrically.
The 2 major methods to prove a conclusion are by indirect proof & by direct proof. These 2 ways will be defined, along with the technique of drawing auxiliary lines. Auxiliary Lines which are created to help prove a statement or they are lines that aren't given in the premises of a proof, but can be drawn to help demonstrate something about a figure or figures. Here we will put all of our knowledge to the examine, to test, not just by deducing things about a figure or figures, but by proving them systematically so that the whole world can learn what we've done
