multiplication table 1-100

Let us learn about multiplication table 1-100

Multiplication is the arithmetical operation of calculating 1 value with another value. This is 1 of the type of operations in basic arithmetic. Multiplication is nothing but the repeated addition. Best example: 2 X 10 = 30, so it represents 10 + 10 = 20, hence for adding the number 10 simultaneously 2 times. Multiplication table is useful for making the multiplication process easier
Student life will be a lot easier when they can simply remember the multiplication tables. So ... train your memory! A multiplication table chart is a mathematical table used to define a multiplication operation for an algebraic system.
The decimal multiplication table chart was traditionally taught as an essential part of elementary arithmetic through out the world, as it lays the foundation for arithmetic operations with our base-ten numbers. Several educators believe it is necessary to memorize the table up to 9 * 9.

what is a radius


Let us learn what is a radius?


The space from the center to the edge of a circle

it is 1/2 of the circle's diameter is called radius
Find the diameter of the circle whose area is 22cm.
Solution:
Given that the area of the circle is 22cm.
Area of the circle = pi *r2
22 = pi * r2
22 = 3.14 * r2
Divide by 3.14 on both sides
22/3.14 = 3.14 * r2/3.14
71.66 = r2
r = √7.01
r = 2.65cm.
Diameter of a circle = 2 * radius
= 2 * 2.65
=5.3cm.

The area of a circle is the number of square units inside that circle.
A circle is a closed smooth curve, each point on the boundary of which is equidistant from a fixed point inside it which is called the centre
Area is the measure of surface occupied by an object. The standard unit for measurement of area is meter square (m2).However the area of smaller dimensions can be expressed in mm2 or cm2. The areas of large dimensions can be expressed in acre or hectare
area of a circle examples
Finding the area of circle with radius equal to 6.5 inch using π = 3.14
Solution:The Area of circle as, A=Ï€r2
Substitute the values of radius and π.
Therefore, A= (3.14 * 6.5*6.5)
Squaring the radius and then multiplying with 3.14 and then we get,
Area=3.14 * 42.25

orthographic drawing

Let us learn about orthographic drawing

A projection on a plane, using lines perpendicular to the plane

Graphic communications has many forms. Orthographics is one such form. It was developed as a way of communicating information about physical objects. It is part of a universal system of drawings. House plans - one well known drawing format, are a form of othographic projection. In simple terms, orthographic drawings are views (front, side, top, and so on) of an object. An orthographic view is only one side. It takes several views to show all the object. Before getting to views, it is useful to look at another type of drawing. Pictorial drawings show several sides at the same time. Many people find pictorial drawings easier to understand. They do not provide as much information as orthographic views. The most commonly used pictorial drawing for technical information is called isometric drawings. Isometric drawings were developed to approximate perspective, but are much easier to draw. For a square box, all the sides are drawn as vertical lines, or at 30 degrees to the horizontal.

Match the orthographic drawing to the isometric drawing.

A ) Figure 4
B ) Figure 2
C ) Figure 3
D ) Figure 1

Steps to derive

1 An orthographic drawing shows the top view, front view and right-side view of a three-dimensional figure.
2 Develop a three-dimensional figure from the orthographic views.
3 Top view forms the base of the structure. A three-dimensional structure is developed from the orthographic views.
4 Figure 2 gives the isometric drawing of the structure developed from orthographic drawing.

Hence the right answer is Option B

least squares regression line

Let us learn about least squares regression line


Regression is the measure of the average relationship between two or more variables in terms of the original units of the data. This can be represented by an equation of a straight line which can be obtained by the method of least squares. The equations are of two forms as y on x and x on y. To obtain them we use the following normal equatons.

(i) Regression line y on x: It is given by y = hx + k.

Their normal equations are:

Σy = hΣx + nk ……………… (1)

Σxy = hΣx 2 + kΣx …………. (2)

By solving (1) and (2), we arrive at the required equation y = hx + k
(ii) Regression line x on y: It is given by x = hy + k.

Their normal equations are:

Σx = hΣy + nk ……….. (1)

Σxy = hΣy 2 + kΣy ………… (2)

By solving (1) and (2), we arrive at the required equations x = hy + k

plot line

Let us learn about plot line

A line plot is defined as a graph that shows frequency of data along a number line. It is best to use a line plot when comparing fewer numbers.
  • A line plot shows data on a number line with the symbol x or other marks to show frequency.
  • In the applications of line plot, we have also created the scatter plot analysis. I we go in the wrong path or plotting the extra values or plotting the values in different place or leaving some values when we plotting make great difference in the diagrams.

Line Plot Maker - Making a Number Line Plot:

  • To define the scale which we use, if the data is described as 100 the scale is increased by 10. So that we define the scale as 10 for 100
  • Next we have to draw the horizontal line to across the paper.
  • Break the grid as per the required scale.
  • Place the data values of x in the x-axis and y in the y-axis.

change of base formula

Let us learn about "change of base formula"

The solving change of base formula is known as formulas which it permits us to rework a logarithm by means of the logs that may be is written with different base.

The change of base formula is given by,

Log a x = log b x / log b a

Here, assume that a, b and x are positive where a≠1 and b≠1.

Problem

Solve log 16 32

Change of base formula => loga x = logbx / logba

log 16 32 = log 2 32 / log 2 16

= 5 / 4

Thus a formula that allows you to rewrite a logarithm in terms of logs written with another base. This is especially helpful when using a calculator to evaluate a log to any base other than 10 or e.
