bar graph examples


Let us learn about bar graphs & bar graph examples

Bar graphs are probably the most famous & most widely used graph types. Bar graphs allow a graphical representation of data in different groups & categories. The length of a bar characterize the numerical amount for a given series point.
Bar graphs are a very general type of graph best suited for a qualitative independent variable. Hence there is no uniform distance between the discrete nature of the individual bars & levels of a qualitative variable are well suited for this type of independent variable. Though you can extract trends between bars e.g., they are gradually getting longer or shorter, we cannot calculate a slope from the heights of the bars.
a) Simple bar graph (b) Double bar graph & (c) Divided bar graph are 3 types of bar graph

mean deviation calculator


Let us learn about mean deviation calculator


The difference between observed value & the expected value of a function is said to be as mean of deviation. The mean deviation is nothing but the mean of the absolute deviation of a set of data about the data's mean. mean deviation is an important expressive statistic which is not frequently used in mathematical statistics. This is essentially mean deviation as the "mean deviation from the mean," the introduction of the complete value makes logical calculations using this statistic much more difficult.
Find the mean deviation for the given values.
16, 22, 10, 32
Sol: Mean (avg) = 20
Deviation(Variation) = -4, 2, -10, and 12
absolute deviation = 4, 2, 10, and 12
Sum of the absolute deviation = 28
mean deviation = 7
Find the mean for the given values.
24, 11, 40
Sol: Mean (avg) = 25
Deviation = -1, -14, and 15
absolute deviation = 1, 14, and 15
Sum of the absolute deviation = 30
mean deviation = 10

composite numbers 1-100



Let Us learn about composite numbers 1-100


Numbers that have more than 2 factors are said to be as composite number. The smallest composite number is four.
The Examples of composite number are as follows:
4, 6, 8, 10, 12, etc.
Note: That numerical ' 1 ' is neither composite number nor prime number, because it has only 1 factor which is 1 itself.
Any composite number will be written as the product of 2 or more prime numbers & this combination is unique for every number. That is the reason, all the natural numbers can be obtained by adding prime numbers in different combination.

Regular Polygon


Let us learn about Regular Polygon.


A regular polygon is a shape that has ‘n’ number of sides of equal length, symmetrical to one another and sharing a common center point.

Perimeter = n*s ( n times s)
where, n = number of sides and n >3, a whole number
s = length of any side

1.Find the area of a 6 sided regular polygon with a side length of 5cm.

Solution:
Area of the polygon = S^2 N
4tan (╥/N)
= 52*6/ [4 tan (pi/6)]
= 25*6/ 2.309
= 150/2.309
area of polygon = 64.96 cm2.

Change in postulate rules


Welcome to free online math tutors,
Over the years, people tried to prove the fifth postulate, thinking
that something so complex must somehow follow from the simpler
postulates. They failed. examples on math forum; In the nineteenth century, mathematicians
tried a different tack: try changing the postulate, and see what
happens.

They found that they ended up with several varieties of
"non-Euclidean" geometry that were completely self-consistent, but
different from Euclid's geometry. Changing the "rules" made a new but
perfectly good game. read more on online math forum.

Scalene and equilateral triangle


Welcome to online math tutor,
The scalene triangle C has no symmetries, but the isosceles triangle B has a bilateral symmetry. The equilateral triangle A not only has three bilateral symmetries, but also has 120°-rotational symmetries.

As defined by Euclid, an equilateral triangle is not to be considered as an isosceles triangle, but in modern terminology,examples on free math tutor; it is usually the case that equilateral triangles are included among the isosceles triangles, that is, it is only required that at least two sides be equal in order for a triangle to be isosceles. Generally speaking, modern definitions are inclusive whereas Euclid's definitions are usually exclusive.

Equilateral triangles are constructed in the very first proposition of the Elements. read more on online math forum.

Math Topology


Welcome to free math tutoring online,
The modern subject of topology studies space in a different way than geometry does. The geometric concepts of straightness, distance, and angle are excluded from topology, but the concept of boundary is central to topology. In topology, a sphere remains a sphere even when it's squeezed or stretched.

Not everything has a boundary. For instance, the circumference of a circle has no boundary. Also a spherical surface has no boundary. examples on math tutoring ; In topology, a finite region with no boundary is called a cycle. Circles and spherical surfaces are cycles. In general, if something is a boundary, it has no boundary itself. So boundaries are cycles. But not all cycles are boundaries.

Topology uses observation to distinguish various spaces. For instance, on a spherical surface, every circle is the boundary of a region on that surface. But on a toroidal surface (rotate a circle around a line in the plane of the circle that doesn't meet the circle), there are circles (for instance, that circle mentioned parenthetically) that don't bound any region on the surface. Thus, spherical surfaces are topologically different from toroidal surfaces. learn more on math forum.

Surface line relation


Welcome to free online math tutoring,
This statement describes a certain relationship, but this time between surfaces and lines. For example, a hemisphere is a surface, and its edge is the circumference of a circle, a kind of line.

This definition cannot actually be used since there are no postulates to go along with it to connect the edges of a surface in any way to the surface.

Euclid uses the same term for the end of a line, the edge of a surface in this definition, and the surface of a solid. free math ;That term could be translated as "that which is around," "the limits of," or "the extremities of," but in English the terms "the ends of" a line, "the edges of" a surface, and either "the surfaces of" or "the faces of" a solid are fairly standard for different dimensions. read more on online math forum.

Math postulates


Greetings from math forum,
We aren't allowed to introduce additional assumptions (undefined terms
or postulates) or alter them without explicitly stating the new
assumptions. When we do so, we are no longer working in the same
mathematical system. It may be a perfectly valid system, but it isn't
the same one once its rules have been changed, even the slightest bit.

Many mathematical systems - probably all until the last two centuries
or so - were motivated by attempts to describe and explain things in
the real world. examples on free math; At this point, math overlaps
with science, and faith
becomes relevant. Do the undefined terms and postulates of our system
correspond to elements of the real world and their interactions? We
can't know. In all likelihood, they don't correspond exactly, but they
may make a good approximation. read more on online math forum.

Calender history


Welcome to free math help online,

10 or 11 days were actually deleted from the calendar in
1582 when we shifted to the Gregorian calendar - should we adjust for
those too, and have the big party on Jan. 10, 2002? I think not.
more examples on math forum.

And finally, if Christ was actually born on Dec. 25, then _that_ year
can be considered "the first year of our lord," i.e. the first year of
the new millennium, and the following year (year 1) is the second.
Which would imply that 2000 ushered in a new millennium.

In short, since the historical/calendric situation is so messy, I
believe that we should measure the millennium by noticing when the big
party is, and Prince doesn't party like it's 2000. I think we're in
the new millennium now. learn more on online math forum.

descending order



Ordering numbers is defined as the numbers while properly arranged set or Putting numbers in order is known as number ordering. Number ordering is generally two types, which are

1. Ascending order,

2. Descending order.

The above two orders are the essential in ordering the numbers and those two number ordering are contains some of the types of number orders.


  1. Match with the given numbers.
  2. Ascending Order - Arranging in increasing order (smaller number to bigger number using <>
  3. Descending Order - Arranging in decreasing order (bigger number to smaller number by using > sign for descending order).
  4. To match like fractions: See the value of numerators and arrange accordingly.
  5. To match with different fractions: Create the denominators general by finding LCM and then compare.

Technical math


Welcome to free online math help,
Technical subjects (like math or chemistry) are often taught
backward, and I wish I could give you a good reason for that, but I
can't. Everyone I knew growing up hated high-school chemistry, and so
did I, because we seemed to spend endless hours doing things like
converting grams to pounds and ounces to liters, and learning to
determine how much of reagents X and Y you'd need to make some
particular amount of reagent Z.

None of which has anything to do with
what's really going on in chemistry! They don't help you understand
why different substances have different colors, why some are
transparent while others are opaque, math help com; why some are hard and brittle
while others are soft and pliable, why water gets larger when it
freezes while most other things get smaller, why fish smell so bad if
they aren't frozen immediately, how two things as different as
diamonds and graphite can be made by arranging the same kinds of atoms
in different configurations... and so on.

It's an enormous, endlessly
fascinating subject - and it almost seems at times as if there is a
conspiracy among high school chemistry teachers to keep all the good
stuff a secret.

Flexible Math


Welcome to free online math tutor,

Mathematics is like silk in that sense. If I take some mathematicians
and put them in nice offices and give them money to take care of their
physical needs, they'll create mathematics, free online math tutoring; i.e., they'll make up
puzzles and solve them.

Now, we can take their solutions and use them
to make all kinds of things - bridges, computers, budgets, animated
movies, flight simulators - but the mathematicians don't (necessarily)
care about any of that. They make mathematics because it's what they
like to do. more on free math homework help.

Math thought


Welcome to math tutors online for free,

Here's another way to think of it. If I put a 2-by-4 on the ground,
could you walk on it from one end to the other without falling off? math help; Of
course, it would be no problem at all.

But what if I placed the same board between two ledges, 500 feet above
a busy street? Now could you walk from one end to the other? It would
be somewhat more difficult, wouldn't it? But it's the same task, isn't
it?

obtuse angles



In geometry mathematics,there are many types are angles presented in the geometry,in which obtuse angle is one of the type.let we see the definition of obtuse angle.
Obtuse angle: when a angle is lies between 90 and 180 then the angle is called obtuse angle. The obtuse angle will not be equal to 90 or 180 it lies in between them.In this article we are going to discuss about the example of obtuse angle.
In a triangle,there is one obtuse angle and one normal right angle. The right angle has divide into two equal parts and find out the obtuse angle of the above example.
given conditions are : 1) one right angle and a obtuse angle
2) right angle has divided equally.
The sum of the triangle is 180 degrees. and the right angle value is 90 degrees. but here the right angle has divided equally so the angle will be = 90/2
= 45 degrees.
now a acute angle has formed which is equal to 45 degrees .
Therefore the obtuse angle = right angel + acute angle
= 90o+ 45o
= 135o

volume of a rectangle





The four-sided figures with opposite sides equal in length which are sometimes referred to as rectangles. The volume of rectangle are find only in three dimensional rectangles such as rectangular prism. The volume of rectangle is specifies an area in the coordinate space that is enclosed by the rectangular object. To find the volume of a rectangle, multiply length into width into height. Volume is generally measured in cubic units such as cubic inches, cubic feet or cubic meters.

Formula: volume of rectangle = l × h × w. Where l = length, h = height and w = width. Such as product of length, height and width.
* Length of the opposite sides is equal.
* Length of the two diagonals is equal.
The interior angle of rectangle is 180 degree.
Volume of rectangle is similar to the volume of parallelogram, it also same like length into height into width.
Find the volume of a rectangle prism whose length l = 4 m and height = 6 m and width = 3m?
Formula: volume of rectangle = l × h × w
= 4 × 6 × 3
= 72m2
