A table student consists of 5 rows and 7 columns. Later on 3 new attributes are added and 2 tuples are deleted. After some time 5 new students are added. What will be the degree and cardinality of the table?
Answer:
The degree of a table refers to the number of attributes (columns) it has. In the case you described, after the 3 new attributes are added, the degree of the table would be 7 + 3 = 10.
The cardinality of a table refers to the number of rows (tuples) it has. In the case you described, after 2 tuples are deleted, the cardinality of the table would be 5 - 2 = 3. After 5 new students are added, the cardinality would increase to 3 + 5 = 8.

For any positive integer S, if we sum up the squares of the digits of S, we get another integer S1. If we repeat the process, we get another integer S2. We can repeat this process as many times as we want, but it has been proven that the integers generated in this way always eventually reach one of the 10 numbers 0, 1, 4, 16, 20, 37, 42, 58, 89, or 145. Particularly, a positive integer S is said to be happy if one of the integers generated this way is 1. For example, starting with 7 gives the sequence {7, 49, 97, 130, 10, 1}, so 7 is a happy number.
Your task is to write a function compute_happy_numbers(range1, range2) , where range1 and range2 are each tuples of the form (lower_bound, upper_bound), and returns a tuple containing: (1) the number of happy numbers in range1, (2) the number of happy numbers in range2, (3) the number of the range (1 or 2) containing more happy numbers, or None if both ranges have the same number of happy numbers.
def compute_happy_numbers(range1, range2):
"""Your code here"""
Test Cases:
compute_happy_numbers((1,1), (1,1)) (1, 1, None)
compute_happy_numbers((1, 10), (11, 100)) (3, 17, 2)
Design and implement a program that reads a series of 10 integers from the user and prints their average. Read each input value as a string, and then attempt to convert it to an integer using the Integer.parseInt method. If this process throws a NumberFormatException (meaning that the input is not a valid number), print an appropriate error message and prompt for the number again. Continue reading values until 10 invalid integers have been entered.
Answer:
Explanation:
The following program was written in Java. It creates a loop that asks the user for numbers. If it can convert it to an integer it accepts it and adds it to the sum variable otherwise it ouputs that it is not a valid number. Once all 10 integers are added it prints the Average of the values entered.

String answer = in.nextLine();
try {
int intAnswer = Integer.parseInt(answer);
sum += intAnswer;
count += 1;
} catch (NumberFormatException e) {
System.out.println("Not a valid number.");
}
}
int average = sum / count;
System.out.println("Average: " + average);

The goal of this problem is to cover all roads with cameras. A camera placed at a station can cover all the roads connected to it. For example, if we place a camera at station 0, the roads (or edges) (0,3) and (0,8) are covered. Note: the edges (0,3) and (3,0) are the same. We want to find all solutions that can cover a network. For example, one solution is to place a camera at each station will cover all roads. In G2, which has 10 stations, this solution is the set {0,1,2,3,4,5,6,7,8,9} or [True, True, True, True, True, True, True True, True, True). Another solution for G2 is {2, 3, 5, 8} or [False, False, True, True, False, True, False, False, True, False, False]. Any road/edge in G2 is connected to one of these 2 or 3 or 5 or 8. Therefore, {2,3,5, 8} is one of the solutions we look for. The code below is almost complete in printing out all solutions, i.e. sets of stations that cover an entire network. What you need to do for this problem is modyfing the is_coverage function, which returns True if the solution is a coverage, and False if it is not. At this time, it's just a placeholder, which always returns True. This is obviously incorrect. You need to fix it. [42]: def is_coverage (solution, G): return True def get_stations(s): return set([i for i in range(len(s)) if s[i]==True]) def cover(G, solution, i): if i==len(solution): if is_coverage (solution, G): print(get_stations ( solution)) else: solution[i] = True cover(G, solution, i+1) solution[i] = False cover(G, solution, i+1)

Indentation is very important in python. You need to indent code inside while loops, for loops, if statements, etc. You don't seem to be indenting.
In this example:
while (secretNum != userGuess):
userGuess = int(input("Guess a number between 1 and 20: "))
Although, you might need to indent more than only this line. I hope this helps.
Pharming involves: setting up fake Wi-Fi access points that look as if they are legitimate public networks. redirecting users to a fraudulent website even when the user has typed in the correct address in the web browser. pretending to be a legitimate business's representative in order to garner information about a security system. using emails for threats or harassment. setting up fake website to ask users for confidential information.
Answer:
Explanation:
Pharming involves redirecting users to a fraudulent website even when the user has typed in the correct address in the web browser. An individual can accomplish this by changing the hosts file of the web address that the user is trying to access or by exploiting a DNS server error. Both of which will allow the individual to convince the victim that they are accessing the website that they were trying to access, but instead they have been redirected to a website that looks identical but is owned by the individual. The victim then enters their valuable and private information into the website and the individual can see it all and use it as they wish. Usually, this is done to steal banking information.
To qualify for a particular scholarship, a student must have an overall grade point average of 3.0 or above and must have a science grade point average of over 3.2. Let overallGPA represent a student’s overall grade point average and let scienceGPA represent the student’s science grade point average. Which of the following expressions evaluates to true if the student is eligible for the scholarship and evaluates to false otherwise?
a: (overallGPA > 3.0) AND (scienceGPA ≥ 3.2)
b: (overallGPA > 3.0) AND (scienceGPA > 3.2)
c: (overallGPA ≥ 3.0) AND (scienceGPA ≥ 3.2)
d: (overallGPA ≥ 3.0) AND (scienceGPA > 3.2)
Answer:
([tex]overallGPA \ge 3.0[/tex]) AND ([tex]scienceGPA > 3.2[/tex])
Explanation:
Given
[tex]overallGPA \to[/tex] Overall Grade Point Average
[tex]scienceGPA \to[/tex] Science Grade Point Average
Required
The expression that represents the given scenario
From the question, we understand that:
[tex]overallGPA \ge 3.0[/tex] --- average [tex]greater\ than\ or[/tex] equal to [tex]3.0[/tex]
[tex]scienceGPA > 3.2[/tex] --- average [tex]over[/tex] 3.2
Since both conditions must be true, the statements will be joined with the AND operator;
So, we have:
([tex]overallGPA \ge 3.0[/tex]) AND ([tex]scienceGPA > 3.2[/tex])

How did the case Cubby v. CompuServe affect hosted digital content and the contracts that surround it?
Although CompuServe did post libellous content on its forums, the court determined that CompuServe was just a distributor of the content and not its publisher. As a distributor, CompuServe could only be held accountable for defamation if it had actual knowledge of the content's offensive character.
What is CompuServe ?As the first significant commercial online service provider and "the oldest of the Big Three information services," CompuServe was an American company. It dominated the industry in the 1980s and continued to exert significant impact into the mid-1990s.
CompuServe serves a crucial function as a member of the AOL Web Properties group by offering Internet connections to budget-conscious customers looking for both a dependable connection to the Internet and all the features and capabilities of an online service.
Thus, CompuServe could only be held accountable for defamation if it had actual knowledge of the content's offensive character.

Hi, I have a CodeHS Python assignment called "Exclamation Points"
the assignment is as follows and I have no idea where to start with this if someone could help me please:
"Words are way more edgy when you replace the letter i with an exclamation point!
Write the function exclamations that takes a string and then returns the same string with every lowercase i replaced with an exclamation point. Your function should:
Convert the initial string to a list
Use a for loop to go through your list element by element
Whenever you see a lowercase i, replace it with an exclamation point in the list
Return the stringified version of the list when your for loop is finished"
Using the knowledge in computational language in python it is possible write the function exclamations that takes a string and then returns the same string with every lowercase i replaced with an exclamation point.
Writting the code;my_string = input("Enter text: ")
my_list = list(my_string)
for item in my_list:
if item == "i":
print "!"
my_list.remove("i")
print item
(" ").join(my_list)
my_string = list(input('Enter string: '))
for i, char in enumerate(my_string):
if char == 'i':
my_string[i] == '!'
print(''.join(my_string))
my_string = input("Enter text: ")

How many rows are in the SFrame?
Answer: It's not possible for me to know how many rows are in a specific SFrame without more information. The number of rows in an SFrame will depend on the data that it contains and how it was created.
Explanation: SFrame is a data structure for storing large amounts of data in a tabular format, similar to a spreadsheet or a SQL table. It was developed by the company Turi, which was later acquired by Apple. SFrames are designed to be efficient and scalable, and they can store data in a variety of formats, including numerical, categorical, and text data.
in a table from identify any three differences between data and information
Answer:
Find the differentiation below.
Explanation:
The differences between data and information can be found below;
Data Information
1. Data is an assembly of facts. Information is a collection of facts but with meaning attached.
2. Data is unstructured. Information is structured.
3. Data is easily comprehended. Information is easily comprehended
because of its organized nature.
In this problem, you will derive the efficiency of a CSMA/CD-like multiple access protocol. In this protocol, time is slotted and all adapters are synchronized to the slots. Unlike slotted ALOHA, however, the length of a slot (in seconds) is much less than a frame time (the time to transmit a frame). Let S be the length of a slot. Suppose all frames are of constant length L = kRS, where R is the transmission rate of the channel and k is a large integer. Suppose there are N nodes, each with an infinite number of frames to send. We also assume that dprop < s,="" so="" that="" all="" nodes="" can="" detect="" a="" collision="" before="" the="" end="" of="" a="" slot="" time.="" the="" protocol="" is="" as="">
⢠If, for a given slot, no node has possession of the channel, all nodes contend for the channel; in particular, each node transmits in the slot with probability p. If exactly one node transmits in the slot, that node takes possession of the channel for the subsequent k â 1 slots and transmits its entire frame.
If some node has possession of the channel, all other nodes refrain from transmitting until the node that possesses the channel has finished transmitting its frame. Once this node has transmitted its frame, all nodes contend for the channel.
Note that the channel alternates between two states: the productive state, which lasts exactly k slots, and the nonproductive state, which lasts for a random number of slots. Clearly, the channel efficiency is the ratio of k/(k + x), where x is the expected number of consecutive unproductive slots
a. For fixed N and p, determine the efficiency of this protocol.
b. For fixed N, determine the p that maximizes the efficiency.
c. Using the p (which is a function of N) found in (b), determine the efficiency as N approaches infinity
d. Show that this efficiency approaches 1 as the frame length becomes large
