Fraction and its types

Let's learn all about fractions in today's post.

What is a fraction? A fraction is a rational number having one numerator and a denominator.

What does fraction represents? Fractions represents ratio, decimals and percentages.

Types of fractions: There are three types of fractions: proper fraction, improper fraction and mixed fraction.

Proper fraction: A fraction where numerator is smaller than the denominator.
Improper fraction: A fraction where denominator is smaller than the numerator.
Mixed fraction: A fraction formed of a whole number and a fraction.

Fraction operations: There are different operations involved with fractions: ordering fractions, comparing fractions, reducing fractions, adding, subtracting multiplying and dividing fractions and so on.

how to do math problems

Let us learn how to do math problems?

Math problems can be fun when you know what you're doing.

Read the question and visualize problem.

Underline what you need to find & underline where you finding difficulty

Circle the important numbers

Choose a strategy

Make a table or chart

Draw a picture

Use logical reasoning

Refer books & double check

0 factorial

Let us solve problem on 0 factorial

0 factorial

Find the value of 0!

0! = 1

Answer is = 1.

0 factorial

Find the value of 6!

Given 6!

= 1×2×3×4×5×6 (Multiply all numbers)

= 720

Answer is 720

linear programming word problems

Let us solve linear programming word problems

Let us take 2 variables x and y to represent the number of chairs & tables respectively.
Hence the price of x tables = 1200x & the price of y chairs = 500y.
Here the total investment cannot be more than 50,000, therefore,
The total price = 1200x + 500y ≤ 50,000. This is the 1st constraint inequality.
Here, hence the storage capacity is for 100 pieces, we have x + y ≤ 100. This is the 2^nd constraint equation. Hence the number of chairs & the number of tables non-negative, we have x ≥ 0, y ≥ 0.
Now, profit on y chairs = 75y. & the profit on x tables is 180 xs
Here, the objective is to maximize the profit, so the objective function is 180x + 75y.
Hence the linear programming model is given by:
Maximize Z = 180x + 75y
Subject to the constraints
1200x + 500y ≤ 50,000
x + y ≤ 100
x ≥ 0, y ≥ 0.

poisson distribution table

Let us learn about poisson distribution table

The number of successes in a Poisson experiment is said to be as a Poisson random variable. A Poisson distribution is referred as a probability distribution of a Poisson random variable.

Best example of Poisson distribution table

The number of alpha particles emanated by a radio-active source in a specified time interval.

The number of mobile calls received at a telephone exchange in a mentioned time interval.

The Poisson distribution is an another discrete probability distribution

probability equations

Let us learn about probability equations

Probability is referred as the branch of mathematics which studies the possible outcomes of given events together with the outcomes' relative likelihoods & distributions. In common usage, the word "probability" is applied to mean the chance that a particular event or set of events will occur expressed on a linear scale from “0” impossibility to 1 certainty, also expressed as a percentage between 0 & 100%. The analysis of events governed by probability is known as statistics.

In a class of sixty students, ten are in the drawing club & fifteen are in the games club. If a learner is selected randomly, what is the probability that the selected learner is:
a) In the drawing club?
b) In the games club?
Probability Equations Solution:
The total number of learner in the class = 60
Number of learners in the drawing club = 10
Number of learners in the games club = 15
The probability of solving that the selected learners in the drawing club is,
P (students in drawing club) = 10 / 60
= 1/6
= 0.17
The probability of solving that the selected learner in the games club is,
“P” students in games club) = 15 / 60
= ¼ = 0.25

frequency distribution table

Let us learn about frequency distribution table
Frequency distribution table is a tabulation of the values that 1 or more variables take in a sample. Each entry in the frequency distribution table contains the frequency or count of the occurrences of values within a particular group or interval, & in this way the table summarizes the distribution of values in the sample.
Frequency distribution table is used to rank the disorganized data from the highest to the lowest. A frequency distribution table is an organized tabulation of the number of individual scores located in each category on the scale of measurement. Frequency distribution table contains at least 2 columns – 1 for the score categories (X) & another for the frequencies (f).
Frequency distribution table can be represented in a number of ways.
Group frequency table as Regular frequency table
Group frequency graph as Polygon; The bar graph; Pie Chart; Histogram
The bar graph is used only when the data or measurements are from a nominal or an ordinal scale. Histogram - Interval or Ratio data, Polygon - Interval or Ratio data

Group frequency distribution table is used when the original scale of measurement consists of more categories which can be listed in a regular table, 20 or more categories is generally considered too much. The easiest & the most complete way to present a set of N= 7 scores is to list each individual score.
