Answer:

(b) srand(time(0))

Explanation:

Given

See attachment for options

Required

Which would generate different set of random numbers

To do this, we analyze each of the options - one at a time.

(a) srand()

The above is an invalid usage of srand() because srand() requires an argument for it to function e.g. srand(2)

(b) srand(time(0))

The above is valid, and it will return different pseudo random numbers each time the statement is executed because time(0) lets srand() seed to the current time.

(c) srand(100)

The above is a valid usage of srand(), however rand() will generate same set of numbers because srand() has been seeded to only 100.

(d) time(srand())

The above is also an invalid usage of srand().

Answer:

The downloads folder ( C )

Explanation:

when you have difficulty locating a file on your computer you can look for the file in any of the options listed ( The recycle bin, Default folders like My Documents  or The Downloads folder )

But the best place out of these three options is the Downloads folder. and this is because by default all files downloaded into your computer are  placed in the Downloads folder regardless of the type of file

Qué tipo de solución alternativa estás buscando

Answer:

ALTER TABLE Products

ADD Products_price float(5,2) DEFAULT 9.99,

ADD Adding_time datetime;

Explanation:

So at first we need to use ALTER TABLE statement, when we use this statement we also need to provide the table name. In this case, i assume it is 'Products'.

Then, as per question, we need to add two columns.

The first one is 'product_price' and it contains decimal points. So, we need to use ADD statement and give a column name like 'Prodcuts_price' and its datatype 'float' because it contains decimal or floating points. so, for 3 digits on the left and 2 digits on the right, it makes a total of 5 digits. So, we need to declare it like this. (5,2) it means a total of 5 digits and 2 after the decimal point. after that, we need to set our Default value using the DEFALUT statement. so DEFAULT 9.99. it will set the default value to 9.99 for existing products.

And for our next column, we give its a name like 'Adding_time' then it's datatype 'datetime' because it will contain date and times.

Systems implementation & evaluation

What is systems implementation?

What are the tools for physical systems design?

What are the issues to consider before an information system is operational?

What are the key indicators of a quality system?

What are the techniques for systems evaluation?

Systems implementation is the process of:

defining how the information system should be built (i.e., physical system design),

ensuring that the information system is operational and used,

ensuring that the information system meets quality standard (i.e., quality assurance).

Systems design

Conceptual design – what the system should do

Logical design – what the system should look to the user

Physical design – how the system should be built

Physical system design using structured design approach:

à To produce a system that is easy to read, code, and maintain

1. Factoring: decomposition

2. Span of control: 9 subordinate modules

3. Reasonable size: 50-100 LOC

4. Coupling: minimize inter-module dependency

5. Cohesion: single module functionality

6. Shared use: multiple calls to lower level modules from different bosses

Structured design tools

· Organization of programs and program modules (structure chart)

· Processing logic specification in each module (pseudocode)

Structure chart – to show graphically

how the various program parts/modules of an information system are physically organized hierarchically

how the modules communicate with each other through data couple (data exchange) and flag (control/message)

how the modules are related to each other in terms of sequence, selection, and repetition

Answer: it is also known as supervised learning

Explanation:

Deep learning is a sub field of machine learning and it refers to an artificial intelligence function that has to do with the imitation of the way that the brain works in the processing data which are used in making decisions.

It should be noted that deep learning is not thesame as supervised learning. While there's no creation of high-level abstraction of input features in the supervised learning, there's formation of abstractions of input features in deep learning.

The statement that  is true is that  Network traffic can be captured using the Tcpdump protocol analyzer.

Network traffic can be taken in using the Tcpdump. This is known to be a kind of packet sniffer that is often used to look and record network traffic on an interface.

An example is when a person capture 1,000 packets through the use of tcpdump. One can then analyze network traffic by using actual network traffic analyzer, which is as Wireshark.

Answer:

b. False

Explanation:

Decomposing and modularizing means that a large software is being divided into smaller named components that have a well-defined interfaces which basically describes the component interactions. The main goal is to place these different functionalities as well as the responsibilities in different components.

Decomposition and modularization forms the principle of software design.

Hence, the answer is false.

Answer:

Central processing unit (CPU)

Explanation:

A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user.

The central processing unit (CPU) is typically considered to be the brain of a computer system. It is the system unit where all of the processing and logical control of a computer system takes place.

Hence, the most important component in a computer is the central processing unit (CPU) because without it, it is practically impossible for the computer to run any software application or program.

Additionally, the component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit on how to respond to informations sent to the processor.

Answer:

In half duplex mode, the signal is sent in both directions, but one at a time. In full duplex mode, the signal is sent in both directions at the same time. In simplex mode, only one device can transmit the signal. In half duplex mode, both devices can transmit the signal, but one at a time.

Answer:

1) The value of x will be 6.

2) The value of y will be 7.

Explanation:

1) The value of x will be 6.  

The enum values are labeled by default from 1. This means that Sun = 1, Mon = 2, Tue = 3 and so on.  

So, x = Mon = 2 and y = Sat = 6  

x increases up to y = 6 in the while loop.  

and then y also increments by 1.  

2)So the value of y = 7.  

You will need actual printf("Sun") or printf("Mon") for printing the actual text for the enum.

Answer:

The program in C++ is as follows:

#include <iostream>

#include <vector>

using namespace std;

int main(){

vector<int> nums;

int num;

cin>>num;

while(num != -1){

 nums.push_back(num);

 cin>>num; }  

for (auto i = nums.begin(); i != nums.end(); ++i){

    cout << *i <<endl; }

return 0;

}

Explanation:

This declares the vector

vector<int> nums;

This declares an integer variable for each input

int num;

This gets the first input

cin>>num;

This loop is repeated until user enters -1

while(num != -1){

Saves user input into the vector

 nums.push_back(num);

Get another input from the user

 cin>>num; }

The following iteration print the vector elements

for (auto i = nums.begin(); i != nums.end(); ++i){

    cout << *i <<endl; }

Answer:

-16000

Explanation:

Given

P(success) = 0.75

Amount generated on success, X = 240000

P(not successful) = P(success)' = 1 - 0.75 = 0.25

Revenue generated, 0

Product development cost = 196000

Profit = Revenue - cost

When successful ; 240000 - 196000 = 44000

Unsuccessful ; 0 - 196000 = - 196000

x __________ 44000 _____ - 196000

P(x) _________ 0.75 _________ 0.25

The expected value ; E(X) = Σx * p(x)

Σx * p(x) = (44000 * 0.75) + (-196000 * 0.25)

= 33000 + - 49000

= - 16000

Hence, the company should not make the product

Answer:

[tex]E = 14.81\%[/tex]

Explanation:

Given

[tex]n = 150[/tex]

[tex]\sigma = 0.78[/tex]

[tex]c = 0.98[/tex]

Required

The margin of error (E)

This is calculated as:

[tex]E = z * \frac{\sigma}{\sqrt{n}}[/tex]

When confidence level = 0.98 i.e. 98%

The z score is: 2.326

So, we have:

[tex]E = 2.326 * \frac{0.78}{\sqrt{150}}[/tex]

[tex]E = 2.326 * \frac{0.78}{12.247}[/tex]

[tex]E = \frac{2.326 *0.78}{12.247}[/tex]

[tex]E = \frac{1.81428}{12.247}[/tex]

[tex]E = 0.1481[/tex]

Express as percentage

[tex]E = 14.81\%[/tex]
