Answer:
D. All of the above
Explanation:
Here are the top six data collection methods:
Interviews. Questionnaires and surveys. Observations. Documents and records. Focus groups. Oral histories.The system of data collection is based on the type of study being conducted. Depending on the researcher’s research plan and design, there are several ways data can be collected.
The most commonly used methods are: published literature sources, surveys (email and mail), interviews (telephone, face-to-face or focus group), observations, documents and records, and experiments.
1. Literature sources
This involves the collection of data from already published text available in the public domain. Literature sources can include: textbooks, government or private companies’ reports, newspapers, magazines, online published papers and articles.
This method of data collection is referred to as secondary data collection. In comparison to primary data collection, tt is inexpensive and not time consuming.
2. Surveys
Survey is another method of gathering information for research purposes. Information are gathered through questionnaire, mostly based on individual or group experiences regarding a particular phenomenon.
There are several ways by which this information can be collected. Most notable ways are: web-based questionnaire and paper-based questionnaire (printed form). The results of this method of data collection are generally easy to analyse.
3. Interviews
Interview is a qualitative method of data collection whose results are based on intensive engagement with respondents about a particular study. Usually, interviews are used in order to collect in-depth responses from the professionals being interviewed.
Interview can be structured (formal), semi-structured or unstructured (informal). In essence, an interview method of data collection can be conducted through face-to-face meeting with the interviewee(s) or through telephone.
4. Observations
Observation method of information gathering is used by monitoring participants in a specific situation or environment at a given time and day. Basically, researchers observe the behaviour of the surrounding environments or people that are being studied. This type of study can be contriolled, natural or participant.
Controlled observation is when the researcher uses a standardised precedure of observing participants or the environment. Natural observation is when participants are being observed in their natural conditions. Participant observation is where the researcher becomes part of the group being studied.
5. Documents and records
This is the process of examining existing documents and records of an organisation for tracking changes over a period of time. Records can be tracked by examining call logs, email logs, databases, minutes of meetings, staff reports, information logs, etc.
For instance, an organisation may want to understand why there are lots of negative reviews and complains from customer about its products or services. In this case, the organisation will look into records of their products or services and recorded interaction of employees with customers.
6. Experiments
Experiemental research is a research method where the causal relationship between two variables are being examined. One of the variables can be manipulated, and the other is measured. These two variables are classified as dependent and independent variables.
In experimental research, data are mostly collected based on the cause and effect of the two variables being studied. This type of research are common among medical researchers, and it uses quantitative research approach.
These are three possible way:
A. Interviews, surveys, the InternetB. Instruments, books, experimentsC. Magazines, manuals, experts. What are the different ways of gathering data?There are many ways to gather data, including:
Surveys and questionnaires: Collecting information through standardized questions, either in written or verbal form.Interviews: Gathering information through face-to-face or telephone conversations.Observation: Collecting data by watching and recording behavior or events.Experiments: Controlled testing to gather data on cause and effect relationships.Case studies: Detailed examination of a particular individual, group, or situation.Focus groups: Discussions with a small group of people to gather information on a specific topic.Online research: Gathering data through the internet using search engines, social media, and other online sources.Library research: Using books, journals, and other printed materials to gather data.Archival research: Examining historical documents, records, and other artifacts.Participatory research: Involving the research subjects in the data collection process.Learn more about data collection, here:

In this lab, you will design a die game called 15. The object of the game is to score exactly 15 points in as few rolls of the die as possible. After each roll, the player can choose to add the current die value to his or her score or not, unless the die value is six, in which case it is automatically added to the player’s score. If the player’s score exceeds 15, the player loses. If the player’s score is equal to 15, the player wins. Play continues until the player reaches or exceeds 15 points.
Description:
To start the game, the player presses the reset switch. The score will be set to zero and both the Win and Lose LEDs will be turned off. The player then rolls the die by toggling the Rb switch to the Roll position. The die counter should operate with a clock frequency of 27 MHz or 50 MHz so that the player cannot control the outcome of a roll. After about a second or more, the player toggles the Rb switch back to the Off position to end the roll. The Turn Counter should be incremented to indicate that the player has taken a roll. If the player rolled a six, it is automatically added to his or her score. Otherwise, the player can press the Add button to add the die value to his or her score or the player can press the Pass button to leave the score unchanged. After each roll, the score will be greater than, less than or equal to 15. If the score is equal to 15, the player wins – the Win LED should be turned on and remain on until the system is reset for a new game. If the score is greater than 15, the player loses – the Lose LED should be turned on and remain on until the system is reset. Once the player has won or lost, the player cannot roll the die again until the system is reset. (The Rb switch will not have any effect in these states.) If the score is less than 15, the player will roll again. After each roll, the player presses either the Add button or the Pass button (unless a six is rolled) before the die can be rolled again. Play continues until the player’s score equals or exceeds 15.

In C++ programming please.
Rock, Paper, Scissors Game.
a) Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows:
1. When the program begins, a random number in the range of 1 through 3 is generated (1+rand()%3). If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, them the computer has chosen scissors. (Don't display computer's choice yet).
2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer).
3. The computer's choice is displayed.
4. A winner is selected according to the rock paper scossors game riles.
Be sure to divide the program into the following functions:
int getUserChoice ();
The getUserChoice function displays a menu allowing the user to select rock, paper, or scissors.
4 to Quit the game
The function then returns 1 for rock, or 2 for paper, or 3 for scissors.
User input validation of the choices
int getComputerSchoice ();
The getComputerChoice function returns the computer's game choice.
It returns 1 for rock (via the ROCK constant), or 2 for paper (via the PAPER constant), or 3 for scissors
determineWinner (int, int);
The determineWinner function accepts the user's game choice and the computer's game choice as arguments and displays the choices, and a message indicating the winner.
void displayChoice (int);
The displayChoice function accepts an integer argument and displays rock, paper, or Scissors.
int main ()

Departments(dept_id, dname, college)
Grades(sid, cid, year, semester, grade)
Write the following queries in SQL. Only use the tables that are absolutely needed for the corresponding query.
1. Find the sids and snames of students who took "Database" course (i.e., cname = ‘Database’) in Fall 2019.
2. Find the average grade of all the students who took "CS327" (i.e., cid=‘CS327’) in Fall 2019. You can assume grade is a numerical attribute.
3. Find the number of distinct courses offered by each department in Fall 2019.
4. Find the sids of students who have taken at least 10 different courses offered by "Computer Science" department (i.e., dname = ‘Computer Science’).
Answer:
The queries for each question are explained.
1. Find the sids and snames of students who took "Database" course (i.e., cname = ‘Database’) in Fall 2019.
The columns sid and sname are taken from students table.
The course name belong to the courses table.
The semester and year belong to the grades table.
To get the final query, all these tables need to be joined in the FROM clause using JOIN ON keywords.
select s.sid, sname
from students s join grades g on g.sid = s.sid
join courses c on g.cid = c.cid
where cname like 'database%'
and semester like 'Fall'
and year=2019
2. Find the average grade of all the students who took "CS327" (i.e., cid=‘CS327’) in Fall 2019. You can assume grade is a numerical attribute.
The grade column is taken from grades table.
The course id belongs to the grades table.
The semester and year also belong to the grades table.
The final query is formed using the grades table only.
select avg(grade)
from grades
where cid like 'CS327'
and semester like 'Fall'
and year=2019
3. Find the number of distinct courses offered by each department in Fall 2019.
The department id belongs to the courses table.
The course id belongs to the grades table.
The semester and year also belong to the grades table.
To get the final query, the courses and the grades tables are joined in the FROM clause using JOIN ON keywords.
select dept_id, count(distinct g.cid)
from courses c join grades g on c.cid = g.cid
where semester like 'Fall'
and year=2019
group by dept_id
what term defines inventiveness uncertainty and futuristic ideas typically deals with science and technology
Answer:
Innovation.
Explanation:
Innovation can be considered the ideal term, because an innovative idea arises from the set of a new technique, method or invention that aims to improve an existing method, standard, or product.
However, added to an innovative idea is the risk, since innovation breaks an already established standard, so it is through science and technology that an invention will gain greater foundation and recognition, which increases its credibility and acceptance.

For this problem, use a formula from this chapter, but first state the formula. Frames arrive randomly at a 100-Mbps channel for transmission. If the channel is busy when a frame arrives, it waits its turn in a queue. Frame length is exponentially distributed with a mean of 10,000 bits/frame. For each of the following frame arrival rates, give the delay experienced by the average frame, including both queueing time and transmission time.
a. 90 frames/ sec.
b. 900 frames/ sec.
c. 9000 frames/ sec
Answer:
(a). 0.1 × 10^-3 = 0.1 msec.
(b). 0.11 × 10^-3 = 0.11 msec.
(c). 1 × 10^-3. = 1 msec.
Explanation:
So, in order to solve this problem or question there is the need to use the Markov queuing formula which is represented mathematically as below;
Mean time delay, t = /(mean frame length,L) × channel capacity, C - frame arrival rate, F. ---------------------------------(1).
(a). Using equation (1) above, the delay experience by 90 frames/sec.
=> 1/(10^-4× 10^8 - 90). = 0.1 × 10^-3= 0.1 msec.
(b). Using equation (1) above, the delay experience by 900 frames/sec.
=> 1/(10^-4× 10^8 - 900). = 0.11 × 10^-3= 0.11 msec.
(c). Using equation (1) above, the delay experience by 90 frames/sec.
=> 1/(10^-4× 10^8 - 9000). = 1 × 10^-3= 1 msec.
Hence, the operating queuing system is; 900/10^-4 × 10^8 = 0.9.

Complete SortedTableMap. The SortedTreeMap from the final lecture uses an AVLTree to implement the SortedMap interface so that the essential methods run in O(log n) time, which is relatively quite good. For this problem, complete the empty SortedTableMap class by using an ArrayList to implement the SortedMap interface. It will not be possible to implement all of the essential methods so that they run in O(log n) time, but your implementation should be as runtime efficient as possible. Specifically, the get method can be done in O(log n) time; some other methods can be done in O(n), some can be done in O(1).

A company with a large number of hosts creates three subdomains under a main domain. For easier management of the host records, how many zones should be used
Answer:
4
Explanation:
For easier management of the host records of the company 4 zones should be used because
subdomain is part of a larger domain and the main domain which is the primary domain is the name which the company have decide to use which will represent the company website address and in a situation where the company
have different domain names in which they had registered, they will need to choose one among the domain which will inturn be their main domain.
Therefore for easier , efficient and effective management of the host records 4 zones will be the best zones to be used.
Example of sub domain is north.example.com
For easier management of the host records, 4 zones should be used
Host record or a DNS host, is simply known as record in one's domain's DNS zone file that is said to create the connection between one's domain and its matching IP address.
It is also called an A or Address record. It is said to links a domain to the physical IP address of a computer hosting that has the domain's services.
4 zones in the subdomain is good because a subdomain is part of a larger domain and the main domain and therefore having four will cater for all.
Its gives a creative approach to the management of DNS, DHCP, and IPAM data.
Conclusively, the use of host records helps to manage multiple DNS records, DHCP and IPAM data.

{30, 20, 10}
{-4, 7, 1}
(ii) For an array of size ????, what is the big-oh runtime of this code in the worst case?
Answer:
See explaination
Explanation:
{1, 2}
Runs only once for 1 < 2
{10, 20, 30}
Runs 1 for 10 < 20
Runs 1 for 10 < 30
Runs 1 for 20 < 30
Total 3 times
{30, 20, 10}
Runs 1 for 30 < 20
Runs 1 for 30 < 10
Runs 1 for 20 < 10
Total 3 times
{-4, 7, 1}
Runs 1 for -4 < 7
Runs 1 for -4 < 1
Runs 1 for -7 < 1
Total 3 times
Generalizing it will run for n*(n-1)/2 so for 2 element it will run for 2*1/2 = 1
For 3 element it will run for 3*2/2 = 3 times
(ii) (3 points) For an array of size , what is the big-oh runtime of this code in the worst case?
Time complexity in Worst case is O(n^2). Reason being it uses two for loop where first loop runs for n time and the second loop runs for n*n time in worst case hence its O(n^2)
Chemical equations of Carbon + water
Answer:
Aqueous carbon dioxide, CO2 (aq), reacts with water forming carbonic acid, H2CO3 (aq). Carbonic acid may loose protons to form bicarbonate, HCO3- , and carbonate, CO32-. In this case the proton is liberated to the water, decreasing pH. The complex chemical equilibria are described using two acid equilibrium equations.

Joe, Kate and Jody are members of the same family. Kate is 5 years older than Joe. Jody is 6 years older than Kate . The sum of their ages squared is 961 years. What are their ages?
Answer:
5, 10 and 16
Explanation:
The sum of their ages is √961 = 31
If Joe is x years old, the equation that follows is:
x + (x+5) + (x+5+6) = 31
This simplifies to
3x = 31 - 11 - 5 = 15
so x=5
From that you can find
Joe = x = 5
Kate = x+5 = 10
Jody = x+5+6 = 16

Create a single list that contains the following collection of data in the order provided:
[1121, "Jackie Grainger", 22.22,
1122, "Jignesh Thrakkar", 25.25,
1127, "Dion Green", 28.75, False,
24.32, 1132, "Jacob Gerber",
"Sarah Sanderson", 23.45, 1137, True,
"Brandon Heck", 1138, 25.84, True,
1152, "David Toma", 22.65,
23.75, 1157, "Charles King", False,
"Jackie Grainger", 1121, 22.22, False,
22.65, 1152, "David Toma"]
The data above represents employee information exported from an Excel spreadsheet. Whomever typed the data in originally didn't give much care to how the information was formatted, unfortunately. Each line of data has in it employee information (the whole number), the name of the employee (the string), and the employee's hourly wage (the decimal number). Some rows have extra information in them from a column in the spreadsheet that no one can remember what its purpose was.
Note that the presence of a couple of new data types in the above - "float" values (the numbers with the decimals in them) and "bool" [short for boolean] values (True and False).
Assume that the above information is a small sample of the company's data. Programmatically sort the information into three different lists: one for employee numbers, one for employee names, and one for employee salary information.
No duplicate data should make its way into the new lists.
For each value in the list containing hourly wage information, multiply the current value by 1.3 (since benefits are about 30% of a person's salary) and store each value in a list called total_hourly_rate. Programmatically determine the maximum value in the list and if it's over over 37.30, throw a warning message that someone's salary may be a budget concern.
Determine if anyone's total hourly rate is between 28.15 and 30.65. If they are, add the hourly rate a new list called underpaid_salaries.
For each value in the list that contains unmodified salary information, calculate a raise in dollars according to the following rules:
If the hourly rate is between 22 and 24 dollars per hour, apply a 5% raise to the current rate. If the hourly rate is between 24 and 26 dollars per hour, apply a 4% raise to the current rate. If the hourly rate is between 26 and 28 dollars per hour, apply a 3% raise to the current rate. All other salary ranges should get a standard 2% raise to the current rate.
Add each new value you calculate to a new list called company_raises.
Design your own complex condition with no fewer than four different truth tests in it (all conditions must be on one line, in other words). Above your condition, write out in comments the exact behavior you are implementing with Python.

Which three statements about RSTP edge ports are true? (Choose three.) Group of answer choices If an edge port receives a BPDU, it becomes a normal spanning-tree port. Edge ports never generate topology change notifications (TCNs) when the port transitions to a disabled or enabled status. Edge ports can have another switch connected to them as long as the link is operating in full duplex. Edge ports immediately transition to learning mode and then forwarding mode when enabled. Edge ports function similarly to UplinkFast ports. Edge ports should never connect to another switch.
Answer:
Edge ports should never connect to another switch. If an edge port receives a BPDU, it becomes a normal spanning-tree port. Edge ports never generate topology change notifications (TCNs) when the port transitions to a disabled or enabled status.Assume variables SimpleWriter out and int n are already declared in each case.

3. All powers of two less than n.
This assignment deals with Logical Equivalences. Review section 1.7 of the text before completing the assignment. The assignment may be handed in twice before it is graded. Consider the statements in the left column of the tables below. Translate each into a propositional statement. In the box below, indicate which two statements are logically equivalent. The gray shaded box is the Equation editor that should be used to enter the propositional expression.
Question 1
Statement Reason
Whenever there is a puppy in the house, I feel happy
If I am happy, then there is a puppy in the house
If there is not a puppy in the house, then I am not happy.
If I am not happy, then there is no puppy in the house
Question 2
Statement Reason
If I am in school today, then I am in CSC231 class
If I am not in school today, then I am not civics class
If I am not in CSC231 class, then I am not in school today
If I am in CSC231 class, then I am in school today
Answer:
Question (1) the statements (i) and( iv) are logically equivalent and statements (ii) and (iii) are logically equivalent. Question (2) the statements (i) and (iii) are logically equivalent.
Explanation:
Solution
Question (1)
Now,
Lets us p as puppy in the house, and q as i am happy
So,
p : puppy in the house, and q : i am happy
Thus,
The Statements
(i) so if there is a puppy in the house, I feel happy : p -> q
(ii) If I am happy, then there is a puppy in the house : q -> p
(iii) If there is no puppy in the house, then I am not happy. : ~ p -> ~q
(iv) If I am not happy, then there is no puppy in the house : ~q -> ~p
Hence, the statements (i) and( iv) are logically equivalent and statements (ii) and (iii) are logically equivalent.
Question (2)
Let us denote p as i am in school today, and q as i am in CSC231 class, and r as i am in civics class,
So,
p: i am in school today, q: i am in CSC231 class, r: i am in civics class,
Now,
(i) if I am in school today, then I am in CSC231 class :p -> q
(ii) If I am not in school today, then I am not civics class :~p -> ~r
(iii) If I am not in CSC231 class, then I am not in school today :~q -> ~p
(iv) If I am in CSC231 class, then I am in school today : q -> p
Therefore, the statements i) and iii) are logically equivalent.

What process is used to convert numbers between the binary system and the decimal system?
ANSWER: D) Look up the number on a binary-to-decimal conversion table
Answer:
The method is easy . Divide the binary number by 2 and write the remainder . Again divide by 2 and write remainder and continue till remainder becomes 1 . Then write all the remainders (0 , 1) in the order . The decimal is converted into binary
If you wanna convert binary into decimal , number the digits of a binary number from right to left and from 0 to how much digits are there. Then the digit 1 or 0 is multiplied by the corresponding power of 2 , which comes after numbering . Add all them and you get them into decimal
Answer:
The answer is D) Look up the number on a binary-to-decimal conversion table.
