Answer:

1- Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware.

What would you have to know about the pivot columns in an augmented matrix in order to know that the linear system is consistent
Scrat [10]

Answer:

The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)

Then satisfying this theorem the system is consistent and has one single solution.

Explanation:

1) To answer that, you should have to know The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)

rank(A)

Then the system is consistent and has a unique solution.

<em>E.g.</em>

\left\{\begin{matrix}x-3y-2z=6 \\ 2x-4y-3z=8 \\ -3x+6y+8z=-5  \end{matrix}\right.

2) Writing it as Linear system

A=\begin{pmatrix}1 & -3 &-2 \\  2& -4 &-3 \\ -3 &6  &8 \end{pmatrix} B=\begin{pmatrix}6\\ 8\\ 5\end{pmatrix}

rank(A) =\left(\begin{matrix}7 & 0 & 0 \\0 & 7 & 0 \\0 & 0 & 7\end{matrix}\right)=3

3) The Rank (A) is 3 found through Gauss elimination

(A|B)=\begin{pmatrix}1 & -3 &-2  &6 \\  2& -4 &-3  &8 \\  -3&6  &8  &-5 \end{pmatrix}

rank(A|B)=\left(\begin{matrix}1 & -3 & -2 \\0 & 2 & 1 \\0 & 0 & \frac{7}{2}\end{matrix}\right)=3

4) The rank of (A|B) is also equal to 3, found through Gauss elimination:

So this linear system is consistent and has a unique solution.

A company wants to use online methods to target more customers. It decides to conduct a market research by collecting the data o
Ronch [10]

Answer:

They could use a CRM

A CRM tool lets you store customer and prospect contact information, identify sales opportunities, record service issues, and manage marketing campaigns, all in one central location — and make information about every customer interaction available to anyone at your company who might need it.

They Could Use PDC

The term “primary data” refers to data you collect yourself, rather than data you gather after another party initially recorded it. Primary data is information obtained directly from the source. You will be the first party to use this exact set of data.

They Could Use Quantitative vs. Qualitative Data

Quantitative data comes in the form of numbers, quantities and values. It describes things in concrete and easily measurable terms. Examples include the number of customers who bought a given product, the rating a customer gave a product out of five stars and the amount of time a visitor spent on your website.

Why Should I Track Users Data:

To ensure it's going smoothly, it's important to keep track of data that directly correlates to the potential success of your business. Key performance and financial metrics can help you address any problems with your business before they occur

The question is about writing a C program that prints the initial letter of Name Ferdous.

Therefore, below is the given complete code that prints the first letter of the name Ferdous.

<em>#include <stdio.h> </em><em>/*import strandard input/output library*/</em>

<em>#include<string.h></em><em> /*import string library to handle string type of data*/</em>

<em> </em>

<em>int main(void) </em><em> /*started the program execution- program entry point*/</em>

<em>{ </em>

<em>char *str = "Firdous";</em><em>   /*char to pointer str contains string "Firdous"*/</em>

<em>int len = strlen(str);  </em><em> /*this line of code is not neccary, but if you print other character for example last character of the name then you can use it*/</em>

<em>printf("First Letter of the name is: %c", str[0]); </em><em>  /*print first letter of the name*/</em>

<em>} </em><em>  /**program terminated*/</em>
