Answer: Primary Research (Focus Group).
Explanation:
Exploratory Research is an inquiry that seeks to understand the basic causal factors of a problem. This effort can serve as the basis of more intensive research later on.
There are basically two methodologies used, which are the; Primary and Secondary methods. While the Primary method's source of information is the concerned group, the Secondary Methods obtain their information from already existing information (Primary sources), such as Interviews, Journals, etc.
In the case of the company in the question, seeking to gain insight into the changes in a product, it would be best for them to consider what some selected costumers (focus group), think about the existing products and their views on subsequent changes. This method of getting information directly from the focus group employs the primary method.
Answer:
hours = 50
full_days = int(hours / 24)
print("The number of full days in " + str(hours) + " hours is " + str(full_days))
Explanation:
Initialize the hours
Since there are 24 hours in a full day, divide the hours by 24. Note that you need to typecast it to the int, because the result is a decimal value by default
Print the values as requested
Answer:
O(n^2)
Explanation:
The number of elements in the array X is proportional to the algorithm E runs time:
For one element (i=1) -> O(1)
For two elements (i=2) -> O(2)
.
.
.
For n elements (i=n) -> O(n)
If the array has n elements the algorithm D will call the algorithm E n times, so we have a maximum time of n times n, therefore the worst-case running time of D is O(n^2)
Answer:
I am going to use the Python programming language to answer this. The source code is given below:
print("Enter your tweet here")
user_tweet = input()
decoded_tweet = user_tweet.replace('TTYL', 'talk to you later')
print("This is the decoded tweet: ")
print(decoded_tweet)
Explanation:
In the program the replace() module was used to replace 'TTYL' with 'talk to you later.'
Attached is the screenshot of the output.
Answer:
Explanation:
1. Authentication is a method for confirming users' identities. Once a system determines the authentication of a user, it can then determine the access privileges for that user. Authorization involves providing a user with permission, including access levels and abilities. For example file access, hours of access, and amount of allocated storage space.
2. Content filtering is a software organizations use that filters content, such as emails, to prevent the accidental or malicious transmission of unauthorized information. Encryption scrambles information into an alternative form that requires a key or password to decrypt. In a security branch, an intruder is then unable to read encrypted information. A firewall is hardware and/or software that guard a private network by analyzing incoming and outgoing information for the correct markings.
3. Intrusion detection software (IDS) features full-time monitoring tools that search for patterns in network traffic to identify intruders.
