Answer:
(D) Expression I and expression Il evaluate to the same value only when A and B differ.
Explanation:
Given
[tex]A\ \&\&\ B[/tex]
[tex]!A\ \&\&\ !B[/tex]
Required
Select the true statement
To do this, I will create the following case scenarios.
(a): [tex]A = true[/tex] and [tex]B = true[/tex]
[tex]A\ \&\&\ B[/tex]
[tex]true\ \&\&\ true \to true[/tex] i.e. true and true is true
[tex]!A\ \&\&\ !B[/tex]
[tex]!true\ \&\&\ !true[/tex]
------------------------------------------------------
[tex]!true = false[/tex]
------------------------------------------------------
So, we have:
[tex]false\ \&\&\ false \to false[/tex]
So:
[tex]A =true[/tex] and [tex]B = true[/tex]
[tex]A\ \&\&\ B = true[/tex]
[tex]!A\ \&\&\ !B = false[/tex]
Hence, options (B) and (E) are incorrect
(b): [tex]A = true[/tex] and [tex]B = false[/tex]
[tex]A\ \&\&\ B[/tex]
[tex]true\ \&\&\ false \to false[/tex]
[tex]!A\ \&\&\ !B[/tex]
[tex]!true\ \&\&\ !false[/tex]
Solve each negation
[tex]false\ \&\&\ true \to false[/tex]
So:
[tex]A =true[/tex] and [tex]B = false[/tex]
[tex]A\ \&\&\ B = false[/tex]
[tex]!A\ \&\&\ !B = false[/tex]
Hence, option (c) is incorrect
(c): [tex]A = false[/tex] and [tex]B = true[/tex]
[tex]A\ \&\&\ B[/tex]
[tex]false\ \&\&\ true \to false[/tex]
[tex]!A\ \&\&\ !B[/tex]
[tex]!false\ \&\&\ !true[/tex]
[tex]truee\ \&\&\ false \to false[/tex]
So:
[tex]A =false[/tex] and [tex]B = true[/tex]
[tex]A\ \&\&\ B = false[/tex]
[tex]!A\ \&\&\ !B = false[/tex]
Case scenarios b and c implies that option (d) is correct because different values of A and B gives the same value of both expression which is false
This also implies that (a) is incorrect.

Correct answer will get brainliest! :)
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)

Consider the following code segment.
int[][] arr = {{3, 2, 1}, {4, 3, 5}};
for (int row = 0; row < arr.length; row++)
{
for (int col = 0; col < arr[row].length; col++)
{
if (col > 0)
{
if (arr[row][col] >= arr[row][col - 1])
{
System.out.println("Condition one");
}
}
if (arr[row][col] % 2 == 0)
{
System.out.println("Condition two");
}
}
}
As a result of executing the code segment, how many times are "Condition one" and "Condition two" printed?
A. "Condition one" is printed twice, and "Condition two" is printed twice.
B. "Condition one" is printed twice, and "Condition two" is printed once.
C. "Condition one" is printed once, and "Condition two" is printed twice.
D. "Condition one" is printed once, and "Condition two" is printed once.
E. "Condition one" is never printed, and "Condition two" is printed once.
Answer:
C. "Condition one" is printed once, and "Condition two" is printed twice.
Explanation:
Given
The above code segment
Required
The number of times [tex]each\ print\ statement[/tex] is executed
For "Condition one" to be printed, the following conditions must be true:
if (col > 0) ---- the column must be greater than 0 i.e. column 1 and 2
if (arr[row][col] >= arr[row][col - 1]) --- the current element must be greater than the element in the previous column
Through the iteration of the array, the condition is met just once. When
[tex]row = 1[/tex] and [tex]col = 2[/tex]
[tex]arr[1][2] > arr[1][2-1][/tex]
[tex]arr[1][2] > arr[1][1][/tex]
[tex]4 > 3[/tex]
For "Condition two" to be printed, the following condition must be true:
if (arr[row][col] % 2 == 0) ----array element must be even
Through the iteration of the array, the condition is met twice. When
[tex]row = 0[/tex] and [tex]col = 1[/tex]
[tex]row = 1[/tex] and [tex]col = 0[/tex]
[tex]arr[0][1] = 2[/tex]

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
