Introduction to laws of probability:
Probability is expressing knowledge that an event will occur or has occurred. Probability is different and it has been defined in different manners. The possibility of happening is called probability.
Probability of an event:
If a sample space consists of n outcomes, m of which are favorable to an event E, then the probability of an event E, denoted by P (E), is defined as the ratio of m to n.
Do you know what is round to the nearest hundredth
P(E)= Number of favorable outcomes for E / Total number of outcomes = m/n

Introduction to define weighted mean:
Let us see about define weighted mean. Weighted mean formula is not anything but its equal as that of arithmetic mean, where as each of the data is indicates uniformly with the weighed value.
If every weighted value is matching, then the weighed mean is comparable to the arithmetic mean. Weighted mean fundamentally executes the parallel fashion to the arithmetic mean.
The phrase weighted mean can also be represented as weighted mean or weighted harmonic average. Do you know what is f test calculator

Introduction to prime factorization calculator

A prime number are natural number that can be only divided by 2 numbers: 1 & itself. For example 1, 3, 5, 11, 13, 17 etc. Numbers which are divisible by other numbers are no prime numbers such as 4 (4=2*2), 6 (6=2*3), & 4 (8=2*4).

A Prime number by which a given number is divisible is a prime factor . For example the prime factors of 6 are 2 & 3. Prime factorization is the way of finding a list of prime factors for a number.Each factor can be written in exponent form

Example:

Prime factorization of a few numbers is shown below:
24 =2 x 2 x 2 x 3= 23 x 3
72= 2 x 2 x 2 x 3 x 3 = 23 x 32
98=2 x 7 x 7= 2 x 72

It is which takes a number as an input & gives the list of prime factorization as its output,you may also look at polynomial calculator.

There's various methods of finding prime factorization by hand. The most often used are;Short Division Process & Factoral trees process.Learninig math is Exploring

Definition:
The probability examples of an event is the measure of how many times event will occur as a result of an experiment. Let us consider the probability of an event A (i.e P(A)) can be defined as the number of ways event A can occur divided by the total number of possible outcomes. The probability of an event A, symbolized by P(A) is given as,
P(A) =
The Number Of Ways EventACanOccur
The total number Of Possible Outcomes
This is the formula for finding the probability of an event.
Whereas,
The Probability is the measure of how likely an event occurs, An event is one or more possible outcomes of an experiment, An outcome is the result of a single trial of an experiment, An experiment is a situation involving chance or probability that leads to results called outcomes.

Mutually Exclusive Events in Probability

A single event can have only one feasible outcome, once an outcome comes there will not be possible of getting other outcomes. This types of results from an event is known mutually exclusive events find probability problems and solutions.

Conditional Probability

Conditional probability is defined as the result of an event depends on the outcome of a preceding event; the Conditional probability of the outcome of a series of events is given as the product of the probabilities of the outcomes of the successive events.
P(A and B) = P(A) * P(B)
The probability of series of events P(A and B) is the product of probability of event A (ie:P(A)) and the probability of the event B (ie:P(B)).

Familiarization with math

Standard Parabola Equation

Find the standard equation:
We have S(a, 0); P(x,y); M(-a, y).
By the definition of conic, we have SP/PM = e
SP / PM =1.
Therefore, SP = PM.
Therefore, SP2 = PM2.
(x - a)2 + (y - 0)2 = (x + a)2 + (y - y)2
x2 - 2ax + a2 + y2 = x2 + 2ax + a2
Simplifying, we will get y2 = 4ax.
The standard equation the parabola is y2 = 4ax.
If the origin is moved to the point V(h, k) and if the new axes X, Y are parallel to x, y axes then the equations for transformations of axes are
x = X + h
y= Y + k
or
X = x - h
Y = y - k

Suppose they think about a parabola with vertex V(h, k) & open to the right.transformations of functions

In terms of Y, X coordinates, the equation of the parabola is of the form
Y2 = 4aX

Understand fractions calculator

Introduction:

             Equivalent fractions calculator is a fraction which may look different but it values will be same when we reduce. To simplifying a fraction here both numerator and denominator must be divided by the same number. In a equivalent fractions calculator we have to canceling down or reducing the fraction. The results can be combined to form fundamental rule of fractions, which is stated as follows. In a equivalent fractions calculator Multiplying or dividing both terms of a fraction by the same number does not change the value of a fraction.

Properties on Equivalent Fractions Calculator:

This is one of the most important rules used which dealing with a equivalent fractions.

  • The numerator and the bottom of a fraction must always be the whole number.
  • The number you choose to divide must be always divided evenly ( no remainders) for both  top and the  bottom numbers.
  • You have to multiply or divide only, never add or subtract, to get an equivalent fraction.
Example:
              Equivalent fractions for  `1/2 ` are `2/4, 3/6, 4/8, 5/10, 6/12, ...`
            
             Equivalent Fractions  to `1/5` are` 2/10, 3/15, 4/20, 5/25, ...`

Explain Mean Deviaition

Introduction to Mean Deviation:
          Today graphics, tables, reasoning, estimation and prediction are playing a very important role in stating the facts in terms of figures.
          Statistics deals mainly in communicating facts and figures in terms of a method called statistical method. Collection, classification, tabulation, representation, reasoning, testing and drawing inferences are part of statistical methods.
The word statistics is used with two meanings. 1. Systematically collected and presented numerical data. 2. Processing the numerical data and to draw conclusions from there.

     The mean deviation of a statistical data is defined as the arithmetic mean of the numerical values of the deviations of items from some average value.
     Mean deviation is also known as average deviation.
     The mean deviation is generally denoted by M.D.

Study on Elementary Geometry

Introduction:
             Geometry is an interesting area of Math that requires a proper understanding of the basics. The fundamentals of Triangles, rectangles and rectilinear figures need to be properly taught in order to understand higher concepts. Basic Geometry is mainly taught at primary and secondary level and it covers some basic concepts of geometry.

Point:

      It is an exact location. It is a fine dot which has neither length nor breadth nor thickness but has position i.e., it has no magnitude. It is denoted by capital letters A, B, C, O etc.

Line segment:

      The straight line path joining two points A and B is called a line segment

Ray:

      A line segment which can be extended in only one direction is called a

Line:

      When a line segment is extended indefinitely in both directions it forms

Different types of Variations

Types of Variation:

  • Direct variation
  • Inverse variation
  • Combined variation
  • Joint variation

 Direct variation:
            Variation with the special function which is defined by using the equation q = kp where k indicates the constant. The above given equation is defined as q varies directly as p or q is proportional to p. Constant k is known as the variation constant or proportionality constant.
Inverse variation:
            Consider any two variables, p & q differ in inverse, then q = k•(1/p) or  p•q = k then k is the constant of proportionality. If there is inverse variation between the variables p and q, then p doubles the value and it results the q to be cut in half. Whenever p is cut in half, then the value of q is doubled.
Combined variation:
            Variation that contains more than two type in variation which occurs in the same time is called as Combined Variation.
Joint variation:
            In a joint variation, there is a variation of quantity which appears in joint and it has equal time in their product. For example, variables are  a, b, and c where k is a constant, a varies jointly as b and c, if a - kbc. Here this joint variation is similar to direct where it contains the exception of having two variable factors, with constant in one number. Variation with variables that differ directly in the product of more than two variables. Equation of joint variation is expressed in terms of Z=kXY where k is used for denoting constant. The equation can be examined by variation of Z in joint with X and Y.

Explain Right Triangle Protractor

Introduction:
         A right triangle, (also called a right-angled triangle), has one angle that is 90 degrees. The other two angles always add up to 90 degrees but can be different sizes. The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle
Define protractor:
       In geometry, a protractor is a circular or semicircular tool for measuring an angle or a circle. The units of measurement utilized are usually degrees.
                                           

More about Right Triangles: 

The Pythagorean Theorem for right triangles:

             This is due to finding right triangle in large quantity in the physical structures of the world around us and the importance of finding perpendicular distance. The very important tools in right angle triangle problem are the Pythagorean Theorem. Proofs that are more different have been written for the Pythagorean Theorem than for any other theorem in geometry. Pythagoras is given credit for developing the subsequent proof based on similar triangles.

Dimensions and types


Introduction:
     The dimension of a space or object is defined as the minimum number of coordinates needed to specify each point within required object.
  • Thus a line has a one dimension because only one coordinate is needed to specify a point on their object.
  • A surface such as a plane, the surface of a cylinder, sphere has a dimension of two because two coordinates are needed to specify a point on it (for example, to locate a point on the surface of a sphere you need both its latitude and its longitude.
  • Inside the cube, a cylinder or a sphere is three-dimensional because three co-ordinates are needed to locate a point within these spaces.                                                                                                                                                                                                                  

      The theory of dimension is not answerable to physical objects. High-dimensional spaces will   happen in mathematics and the sciences for lots of reason, frequently as arrangement spaces such as in Lagrangian or Hamiltonian mechanics; these are theoretical spaces, independent of the physical space we live in.  So we need 4-dimensional universal relativity for High –dimension.

Types of Dimensions:

There are 3 types of dimensions,
  •  One dimension (1D)-It enclose only lengths of object.
  • Two dimension(2D)-It enclose length and breadth.
  • Three dimension(3D)-It encloselength, height and depth.
