We’ve shown that matrix multiplication is generally not commutative, meaning that as a general rule for two

ValentinkaMS [17]

Answer:

a) Observe that

$G=\left[\begin{array}{ccc}2&6\\4&0\end{array}\right] =2\left[\begin{array}{ccc}1&3\\2&0\end{array}\right] =2F$

Then, $FG=F(2F)=2FF, \text{ and } GF=(2F)F=2FF$

b) The zero matrix satisfies that for every matrix B such that the product is well defined, $0B=0=B0.$

Since the matrix G is the zero matrix then $FG=F0=0F=GF$

c) The identity(Id) matrix satisfies that for that for every matrix B such that the product is well defined Id*B=B=B*Id. Observe that G is the identity matrix, then FG=F*Id=F=Id*F=GF

d) Observe that

$G=\left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right] =3\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right] =3Id$ .

Then $GF=3Id*F=3F\\FG=F(3Id)=3F*Id=3F$

What is the other name for data preparation stage of knowledge discovery process.

dmitriy555 [2]

ETL is the other name for 'Data Preparation' stage of knowledge discovery process.

Explanation:

ETL can be defined as a technique for extracting data from various RDBMS systems.
The extracted data will then be 'transformed and loaded' into Data warehouse system.

The development of an ETL process include various stake - holders, analysts, developers, testers and it is technically challenging.

This process is a recurring process where it needs to be automated, and well - documented.

It is also considered to be another name for 'Data Preparation' Stage of 'Knowledge Discovery Process'.

A regular hexagon has 18 sides calculate the size of each interior

Liula [17]

Answer:

$160$ °

Step-by-step explanation:

An alternative method is to use the exterior angle.

the sum of the exterior angles is ALWAYS 360 °

So you can find the size of the exterior angles of a regular polygon quite easily:

If there are 18 sides ( n = 18 ) , then each exterior angle is:

$\frac{360}{n} =\frac{360}{18} = 20$ °

The sum of the exterior and interior angles is 180° because they are adjacent angles on a straight line.

∴ each interior angle is 180° - 20° = 160°
