The Meadian of a Math Problem

Introduction to the median of a math problem:

Let us see about the topic the median of a math problem in probability theory and statistics, a median is explained as the numeric worth separating the top half of an example, a people, or a probability distribution, from the subordinate half. The median of a limited list of statistics can be established by arranging all the explanation from low value to the top value and pick the middle one. Some example problems and practice problems using median of a math are given below.

Example Problem for the Median of a Math Problem.

Example:1

Calculate the median of the following sequence numbers

10, 4, 9, 7, 13, 7, 17, 14.

Solution:

Initial place the numbers of  values in an ascending order .

4,7, 7, 9,10, 13, 14, 17.

The integer of sequence values is 8, an even numeral. Therefore the median is the average of the 2 middle values.

4,7, 7, 9,10, 13, 14, 17

Average of two middle values is 9 and 10

Meadian = 9 + 10/2

= 19/2

= 9.5

Example :2

Try to calculate arithmetic meadian of 6,7,9,4,1,2

Solution:

Given, 1,2,4,6,7,9
Calculate the whole digits are given.

Here  6 numbers in the circulation.

Put the digits in ascending order.
1,2,4,6,7,9
The whole numbers in the distribution (6) is even.
The middle value can be designed using the formula.

` (n/2) `
So the middle value is   `6/2` = 3 and 4
The number at 3rd and 4th position is 4 and 6

Median = `10/2`

Example :3

Try to calculate arithmetic meadian of  7,8,10,5,2,4

Solution:

Given:2,4,5,7,8,10

Calculate the whole digits are given.

Here  6 numbers in the circulation.
Put the digits in ascending order.
2,4,5,7,8,10
The whole numbers in the distribution (6) is even.
The middle value can be designed using the formula.

`(n/2)` +1
So the middle value is `(6/2)` +1 = 3 and 4
The number at 3rd and 4th position is 5,7

Calculate the median =  `(5 + 7)/2`

Meadian = `12/2` = 6

Practice Problem for the Meadian of a Math Problem.

Different Types of Interest

Introduction of different types of interest:

Let us see about different types of interest. The interest is especially necessary for our everyday life and also this most imperative and interesting part in mathematics. This is the essential of much economic estimation. This is the adequate technique of earn the money. For illustration, finance and deposits. In bank areas the interest is one of the most central jobs for earn the money.

Definition:

Interest is the charge of somebody pays for the short-term implement. The interest may be depends on the principal amount. The interest is competent to be signifying during the percents per year or percents per month.

Different types of interest:

There are two different types of interest that it follows by the economic department like insurances, banks and etc.  The different types of interest are following below:

Interest 1: Simple interest.

Interest 2: Compound interest.

Interest 1: Simple interest:

The simple interest is one different category of the interest. The simple interest may be controlling the interest basis on their major amount.

Interest 2: Compound interest:

The compound interest is one different category of the interest.  The compound interests same as the simple interest. The compound interest happens to, if the interest comprise more than one year.

Formula:

Let us see the formulas for different types of interest.

1.    Simple interest:

The formula for the simple interest = P * N * R.

Explanation:

P point outs the principal amount.

N point out the number of year.

R point out the interest rate.

2.    Compound interest:

The formula for the compound interest = C (1 + r/ n) n *t.

Explanation:

C Point out initial deposit.

R Point out interest rate.

N Point out the times per year.

T Point out the number of years invested. Having problem with Imaginary Number keep reading my upcoming posts, i will try to help you.

Examples:

Let us see some examples of the different types of interest.

Example 1:

Find the simple interest, where Principal amount is 5000, rate is 0.09 with 3 years.

Solution:

The formula for simple interest = P*N*R.

= 5000 *0.09 *3.

=1350.

The cost of 1350 is simple interest.


Problem 2:

Find the compound interest where the principal amount is 8000, rate is 0.07 and compound quarterly 5 times per year. The money will stay account for 1 year.

Solution:

The formula for compound interest = P (1 + (r/n))nt.

= 8000 * (1 + (0.07 /5) 5*1.

= 8575.90.

The 8575.90 is compound interest.

Percentage difference

We usually come across perc in many phases in our lives. We get the marks in perc and the discount to tells you about this much perc off. In this section we will discuss about Finding Percentage Difference.  This is usually done when you need to compare an old value to a new value. And this is done only on same kind of things. For example: - To compare weights, heights, shoe size or anything else. Now how do us Find Percentage Difference.  I like to share this Equation for Percent Difference with you all through my article.

The Formula for Percentage Differenceis difference between two values divided by average of the two values, with a % sign. So this is actually a three steps process mentioned below: -
1. Find the difference between two numbers or values given; ignore the negative sign if any.
2. Find the average of two numbers by adding them and dividing by two.
3. Divide the two results obtained in first and second step that is dividing difference by the average obtained.
4. Multiply by hundred and add a ‘%’ sign.
For example: - Outside the amusement park, there are two ticket stalls. Stall one sold45 tickets and stall two sold a total of 35 tickets. Now what is the Percentage of DifferenceHere? First of all we calculate the difference between two which is 45-35 which give 10.

Now the average of these two numbers are (35+45)/2 which is 40. Now we set up the Equation for Percent Differencewhich is 10/40 *100 that results in 25. By adding a % sign to it makes it 25 %. Hence we can conclude that perc difference between 35 and 25 is 25%.

We can calculate perc difference only for similar kind of values and things. Now let us discuss one more example. In a company, Sammy works for 10 hours and Sherry works for 14 hours. What is the perc difference between their numbers of working hours? In the first step, we find the difference between their numbers of working hours.

Difference is 10 minus 14 which equals to negative four. We can ignore the negative here which will make it four. Now the average between these two numbers is (10+14)/2 which is equal to 12. Now the equation becomes 4/12 * 100 which equals 33.33 and we can add a ‘%’ sign to it by making it 33.33%.

Basic Statistics Terms

Introduction to basic statistics terms:

In math, Statistics should be the formal science of generating the perfect help of mathematical data that are involving to collection of individuals. The math basic terms, statistics should be either singular or else plural. The statistics problems include the main concepts of help with mean, median, mode and range. In this article we are going to see few example problems for help with math statistics. Having problem with Example of Descriptive Statistics keep reading my upcoming posts, i will try to help you.

Types of Standard Deviation:

Standard deviation in statistics it can be different as three types it can be shown below,

Mean Deviation of the mean in statistics
Mean deviation of the median in statistics
Mean deviation of ungrouped data in statistics

Basic Terms in Statistics

The basic statistics terms are shown below,

Mean in statistics
Median in statistics
Mean in statistics:

We can estimate the mean with the relation as total of whole number of fundamentals is divided by the number of statistics.

Median in statistics:

We can place the given statistics as the arrange like the ascending and the descending order so if arrange those plan means we can inform the center number is the median or if the information is include the even number means we use can add those middle two numbers and then separated it by 2 ,we obtain the median .
Please express your views of this topic solving systems of equations examples by commenting on blog.

Example Problems for Statistics:
Now we can see about examples of basic statistics terms.

Example 1:

To solve the mode of  the numbers 9,1,5,7,3,4,9,2,8,9,6,9.

Solution:

Given numbers is 9,1,5,7,3,4,9,2,8,9,6,9.

Ascending order of numbers = 1,2,3,4,5,6,7,8,9,9,9,9

Here, the digit '9' is repeating 4 times.

So, Mode value of the particular numbers is 9.

Mode = 9

Example 2:

To solve the range of given numbers 12, 2,8,6,9,5,10.

Solution:

Given numbers is, 12, 2,8,6,9,5,10.

The largest number = 12

The smallest number = 2

Therefore, Range = largest number - smallest number

= 12 - 2

= 10

Example 3:

Which is the median of the given numbers sets, 10, 12,22,29,32,42,55,61.

Solution:

Given, data sets are, 10, 12,22,29,32,42,55,61.

Initial step is finding the arrangement list of numbers. That is, 10, 12,22,29,32,42,55,61.

Now, total integers is even = 8

So, Median = m1 + m2/ 2

Now, m1 and m2 are the two center terms of the given numbers sets = 29 and 32

Therefore, Median = 29+32/2

= 61/2

= 30.5
