Central Tendency

Let's learn about statistics central tendency here in this post.

There are three measures of central tendencies in statistics and these are as follows namely:

• Mean
• Median
• Mode

Next time i will share with you helping hand for statistics binomial distribution.

Volume calculations

Volume calculations:
The aggregate of a actuality is the bulk of amplitude amid by the substance. If the actuality is a solid, again its aggregate is ample out by the geometrical blueprint or the applications of the geometrical formulas of the appearance of that solid.
Therefore the aqueous aggregate calculator is annihilation but the aggregate of alveolate (or the capacity) of assorted shapes

Vector Geometry

Vector Geometry:
The chat agent is acquired from Latin chat " to backpack " and came into actuality because of Hamilton.
Vectors are ideal accoutrement for the abstraction of abounding account in geometry and physics. Agent algebra is broadly acclimated in the abstraction of assertive blazon of problems in Geometry, Mechanics, Engineering and added branches of Applied Mathematics.

Geometric sequence

Geometric sequence formula

The sum of the terms of all the given terms of a geometric sequence is called as a geometric series. Thus, the general form of a geometric sequence is,

a, ar, ar², ar³, ar⁴……

and that of a geometric series is,

a + ar + ar² + ar³ + ar⁴ +…..

The nth term of a geometric sequences with initial a and the ratio r is given by,

a_n = ar^n-1

Here, r → common ratio, n → total no. of terms in the series

Such a geometric sequences may follows the recursive relation in some cases,

a_n = ra_n-1 for every integer n>=1

Here, r → Common ratio, n → no. of terms in the series

For checking whether the given sequence is geometric or not, we have to simply check whether successive entries in the sequence all have the same ratio. For instance,

1, −2, 4, −8, 16, −32…

is a geometric sequence with r value −2.

Segment

A line Segment

• A segment is the small part or small distance of a straight infinity line, which is having two end points on both directions of an infinity line.
• That straight line is joining those two end points, those two points are coordinate points and it is doesn’t extending the line after the end points.

Pie Problems

What is pie:
Example 1:

Find the area of a circle with radius14.4 cm (using pi equal 3.14)?

Solution:
Step 1: Area of a circle = pi* radius².
Step 2: We know that radius = 14.4 cm.
Step 3: Plug the radius value in to the formula.
Step 4: Therefore, Area of a circle = 3.14 *14.4 *14.4
Step 5: So, we get 651.1104 cm².

Pair of Factors

Factors of 56

The product of any three numbers gives a definite number. That three numbers are called as factor pairs of a definite number.
For example think about the number 18.
2 * 9 = 18
3 * 6 = 18
Factor pair of 16 is (2, 9), (3, 6) (know more about prime numbers)
