WAVES AND SOUND
Wave
A wave is motion of vibratory disturbance in a medium or free space which carries energy from one point to another point without any actual transfer of the particles of medium.
There are three types of waves

# Functions¶
Variables are one of the two fundamental components of any programming language. Now that we know what variables are (they things that store data) and how to work with them, we can introduce the the other fundamental component of programming: functions.
Functions give us the ability to write some code th... | {} |

${x}^{6} + 18 {x}^{5} + 135 {x}^{4} + 540 {x}^{3} + 1215 {x}^{2} + 1458 x + 729$
#### Explanation:
The binomial series gives you :
${\left(a + b\right)}^{6} = {a}^{6} + 6 {a}^{5} b + 15 {a}^{4} {b}^{2} + 20 {a}^{3} {b}^{3} + 15 {a}^{2} {b}^{4} ... | {} |

c), the variance is 8.24
#### Explanation:
The variance of a set of data, ${\sigma}^{2}$, is calculated by the expression:
${\sigma}^{2} = \frac{\sum {x}^{2}}{n} - {\left(\frac{\sum x}{n}\right)}^{2}$
Where $x$ represents the data and $n$ represents the number of items of data. So f... | {} |
