Applied Statistics

Applied Statistics is nothing but applying statistics in real life. There are different levels of measurement that are used in applied statistics. Below are few example:

Nominal
Interval
Ordinal
Ratio

Learning Geometry
Mutual geometry software (IGS, or propellant geometry environments, DGEs) are computer programs which figure one to create and then cook geometry tutor free, primarily in glide geometry.

In most IGS, one starts constituent by swing a few points and using them to delineate new objects such as lines, circles or additional points. You can also check geometry answers online.

After whatsoever thinking is through, one can act the points one started with and see how the construction changes. Also get information on geometry problem solver

Learn online calculus homework

After all, many professional engineers do not hesitate to admit their ignorance of the subject.
As a student you probably view calculus as another illogical memorization of equations that one needs to pass through school.The best engineers only need the number crunching to confirm what they think the result may be. Also get help with calculus answers solved

Multivariable calculus
A study of limits and continuity in multiple dimensions yields many counter-intuitive results not demonstrated by single-variable functions. More help with calculus problems solved. The multiple integral expands the concept of the integral to functions of many variables.

Understnading logical reasoning

Let us learn Logical reasoning test

Following are samples of logical test questions that are usually asked in entrance examinations, topics like logical puzzles, word problems, series completion, clocks problems, coding decoding all these are included under logical reasoning.

All the nine digits are arranged here so as to form four square numbers 9, 81, 324, 576 how would you put them together so as to form a possible square number and a single largest possible square number?
The lowest square number i can think of containing all the nine digits once and only once is 139854276 which is square of 11826 and the highest square number under the same conditions is 923187456 which is the square of 30384. Also get help with relatively prime

Inverse Variation

In an Inverse variation, the values of the two variables change in an opposite manner - as one value increases, the other decreases..

Given two variables x and y, the statements

y varies inversely as x,

y is inversely proportional to x.

all mean that y=kx, for some fixed nonzero real number k. The constant k is called the constant of variation or constant of proportionality.

Simple inverse variation problems consist in find a formula and verify what happen with a quantity when we change the other quantity of the problem.

Direct variation relations have the form y = kx where x and y are variables and k is a non-zero constant. When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation.

In simpler terms, that means if A is always twice as much as B, then they directly vary.

Above are different types of variations.

CIRCLE SEGMENT

A circle segment is an area of a circle informally defined as an area which is "cut off" from the rest of the circle by a secant or a chord. The circle segment constitutes the part between the secant and an arc, excluding the circle's center.

A closed interval corresponding to a finite portion of an infinite line is known as a Line Segment. Line segments are generally labeled with two letters corresponding to their endpoints, say A and B, and then written AB.

The segment of the circle is the region bounded by a chord and the arc subtended by the chord. Finding the circle segment area is very similar to working with the area of a sector.

Multiplying and Dividing Radicals

Our today’s topic is Multiplying and Dividing radicals.

Radicals involve the use of the radical sign (√). Sometimes these are called surd. The radical sign is generally taken to indicate the principal root of the radicand, although any radicand will have n different nth roots. The term radical is sometimes used loosely to refer to the entire expression consisting of radical sign and radicand. A radical is a symbol for the indicated root of a number, for example a square root or cube root; the term is also synonymous for the root itself.

The expression &NA; = P is called the radical expression, where n is the indicated root index, R is a real number and P is the nth root of number R such that Pⁿ = R.

How to Simplify Radical Expression:

You can simplify radical expression by involving variables and also numbers. When using radical expressions you will be able to break down the number into smaller pieces.

The product of two radicals with same index n can be found by multiplying the radicands and placing the result under the same radical. For example, √9 × √25 = √(9×25) = √225 = 15, which is equal to 3 × 5 = √9 × √25. Similarly, radicals with the same index sign can be divided by placing the quotient of the radicands under the same radical, then taking the appropriate root.

Example problem on Radical Expressions Calculator:-

Solve the radical expression √30

Solution:

Given that √40

√40 written as √4 * 10 = 40

√40 = √4 * 10

= √2² * 10

4 has multiples of 2*2 =4

= √2² √10

= 2 √10

The solution is 2√ 10
