Answer 1

In order to create a second function for substitution box S2_function() that replicates the S1_function().

We can then create a round function called round1() that takes a binary character vector of length 12 and key K of length 9 and does the following:Divide the block into two equal halves called L0 and R0.Create two subkeys K1 containing the first 8 digits of K and K2 that contains the last 8 digits of K.Expand R0 from 6 to 8 bits and call it ER0.Take the XOR of the result of ER0 with K1. Store the first 4 bits in a variable called block1 and the last 4 bits in a variable called block2.Call S1_function with block1 as its parameter.

Call S2_function with block2 as its parameter.Concatenate the results of e) and f) and store the result in a variable called FR0.Take the XOR of FR0 and L0 and store the results in R1.Store R0 to L1.Return L1 concatenated to R1.We can also create a second function called round2() that is similar to round1() except that it uses K2 and returns the concatenation of R2 and L2.To encrypt the message "Wire $2000 to Bob" using the functions we wrote above following the simplified DES discussed in class, we have to first convert it to binary and then divide it into blocks of 12 bits each. We can then perform the following steps:

Generate the key K by converting it to binary and truncating it to 9 bits.Apply round1() with K1 and round2() with K2 for 3 rounds each, using the output of each round as input to the next.XOR the final output with the key K and return the ciphertext.To modify the functions round1() and round2() such that they can be used for decryption, we have to use K2 instead of K1 for round1() and K1 instead of K2 for round2(). We can also add a third parameter to the two functions round1() and round2() to indicate whether we are encrypting or decrypting.

The new vertex v is the root of T root → T1 T2 (a) Prove that a full binary tree has an odd number of vertices. An integer x is odd if x 2k+1, for some integer k

Answers

A full binary tree has an odd number of vertices.

To prove this, we will use mathematical induction.

Let T(n) be a full binary tree with n vertices.1.

Basis: We begin by demonstrating that a full binary tree with a single vertex has an odd number of vertices.T(1) is defined as a single vertex with no edges.

The root is the only vertex in the tree.T(1) = 1. 1 is an odd number, as it can be written as 2k+1, where k = 0.2.

Inductive hypothesis: Let T(n) be a full binary tree with n vertices, and assume that T(n) has an odd number of vertices.

3. Recursive rule: If T1 and T2 are full binary trees, then a new tree T can be constructed by first placing T1 to the left of T2, adding a new vertex v at the time and then adding an edge between v and the root of T1 and an edge between v and the root of T2.

The new vertex v is the root of T.root → T1 T2We may obtain T(n+1) from this recursive rule by setting T1 to T(n) and T2 to T(1).

Thus, we have:T(n+1) = T(n) T(1) + 1

Since T(n) has an odd number of vertices (by the inductive hypothesis) and T(1) has one vertex (odd), T(n+1) must have an odd number of vertices, as any odd number plus one is an even number. Since the number of vertices in a full binary tree T(n+1) is odd, the statement is true for any full binary tree.

Explanation:

because incident details are often unknown at the start, command should not be established until after the incident action plan has been developed T/F

Answers

True, command should not be established until after the incident action plan has been developed because incident details are often unknown at the start.

Establishing command is a crucial step in incident management and involves designating a person or team responsible for overall coordination and decision-making during an incident. However, it is generally recommended that command should not be established until after the incident action plan (IAP) has been developed, especially when incident details are unknown at the start.

The development of an IAP requires a thorough understanding of the incident, including its nature, scope, and potential impacts. Gathering this information allows incident management personnel to assess the situation, identify objectives, and determine the appropriate strategies and resources needed to address the incident effectively.

By waiting until the IAP has been developed before establishing command, the incident management team can ensure that the command structure aligns with the identified incident objectives and strategies. It also allows for a more informed decision regarding who should assume command based on their expertise and the incident's specific requirements.

Establishing command before developing the IAP can lead to ineffective coordination and decision-making as the incident details unfold. It is essential to have a clear understanding of the incident's scope and objectives before designating a command structure to ensure a coordinated and efficient response.

Which of the following is the date to record dividends(a contra account to retained earnings) in case of cash dividends? a. Dividends payment date b. Date of closing stockholeders' record c. Date of declaration date d. Date of information

Answers

Dividends are recorded on the date they are declared by the company's board of directors. Therefore, the correct option is (c) Date of declaration date.

In the case of cash dividends, the date to record dividends (a contra account to retained earnings) is the date of declaration. When a company's board of directors declares dividends, they formally announce their decision to distribute a portion of the company's earnings to its shareholders. At this point, the company incurs a legal obligation to pay the dividends to the shareholders. Therefore, the date of declaration is the appropriate date to record the dividends in the accounting books as a reduction in retained earnings and an increase in the dividends payable liability. The dividends payment date (a) is when the actual distribution of dividends takes place, and the date of closing stockholder's record (b) is the date on which the shareholder's eligibility for receiving dividends is determined. The date of information (d) is not directly relevant to recording dividends.Therefore, the correct option is (c) Date of declaration date.

let a, b, s, and t be integers. if a mod st = b mod st, show that a mod s = b mod s and a mod t = b mod t. what condition on s and t is needed to make the converse true?

Answers

If a mod st = b mod st, then it follows that a mod s = b mod s and a mod t = b mod t.

To prove that if a mod st = b mod st, then a mod s = b mod s and a mod t = b mod t, we can start by expressing a and b in terms of s and t:

a = q1(st) + r1 (1)

b = q2(st) + r2 (2)

where q1, q2, r1, and r2 are quotients and remainders.

Now, let's consider a mod s:

a mod s = (q1(st) + r1) mod s

= r1 mod s

Similarly, for b mod s:

b mod s = (q2(st) + r2) mod s

= r2 mod s

Since a mod st = b mod st, it implies that r1 = r2 (as both are the remainders when divided by st).

Now, let's consider a mod t:

a mod t = (q1(st) + r1) mod t

= q1(st) mod t + r1 mod t

= q1(t) mod t + r1 mod t

= r1 mod t

Similarly, for b mod t:

b mod t = (q2(st) + r2) mod t

= q2(t) mod t + r2 mod t

= r2 mod t

Again, since a mod st = b mod st, it implies that r1 = r2, and consequently, a mod t = b mod t.

In summary, if a mod st = b mod st, then it follows that a mod s = b mod s and a mod t = b mod t.

To make the converse true, we need the condition that s and t are relatively prime, meaning they have no common factors except for 1. If s and t are relatively prime, then we can deduce that if a mod s = b mod s and a mod t = b mod t, then a mod st = b mod st. This condition ensures that the congruences with respect to s and t combine to yield the congruence with respect to st.

Answers

To retrieve the price of the ordered item from the Product Pricing table using the VLOOKUP function in cell G16, you can follow these steps:

Make sure you have defined the name "ProductPrice" for the Product Pricing table in the Pricing and Shipping worksheet. To do this, select the table, go to the Formulas tab, click on "Define Name" (in the Defined Names group), and enter "ProductPrice" as the name.

In cell G16, enter the following formula:

=IF(ISBLANK(OrderedItem), "Error: No item selected", VLOOKUP(OrderedItem, ProductPrice, 2, FALSE))

This formula uses the IF and ISBLANK functions to check if the OrderedItem cell is empty. If it is empty, it displays the error message "Error: No item selected". Otherwise, it uses the VLOOKUP function to search for the value in the OrderedItem cell within the ProductPrice range (the defined name for the Product Pricing table). It retrieves the corresponding price from the second column (assuming the price is in the second column of the table) and returns it as the result.

Make sure to adjust the range and column index (2) in the VLOOKUP function based on the structure of your Product Pricing table.

Answers

To construct a Huffman code for a random variable X, we first sort the probabilities of the outcomes in decreasing order.

Then, we group the two (or three, for ternary encoding) smallest probabilities and create a parent node with probability equal to the sum of the children's probabilities. We repeat this process until all the outcomes are combined into a single group, which forms the root of the binary (or ternary) tree. The binary (or ternary) code for each outcome is obtained by traversing the tree from the root to the leaf corresponding to that outcome.

For the given random variable X, the binary Huffman code is obtained as follows:

Sort the probabilities in decreasing order:

x1: 0.49

x2: 0.26

x3: 0.12

x4: 0.04

x5: 0.04

x6: 0.03

x7: 0.02

Group the two smallest probabilities and create a parent node:

x6: 0.03

x7: 0.02

Combined: 0.05

Repeat until all outcomes are combined:

x4: 0.04

x5: 0.04

Combined: 0.05

x6: 0.03

x7: 0.02

Combined: 0.05

x3: 0.12

Combined: 0.17

x2: 0.26

Combined: 0.43

x1: 0.49

Combined: 1.00

Create the binary Huffman code:

x1: 0

x2: 10

x3: 111

x4: 1100

x5: 1101

x6: 1000

x7: 1001

The expected code length for this encoding is the sum of the products of the probabilities and their corresponding code lengths:

(0.49 x 1) + (0.26 x 2) + (0.12 x 3) + (0.04 x 4) + (0.04 x 4) + (0.03 x 4) + (0.02 x 4) = 1.96.

n this assignment, you will implement two approximate inference methods for Bayesian networks, i.e., rejection sampling and Gibbs sampling in the given attached base code.
Grading will be as follows:
Rejection sampling: 70%
Gibbs sampling: 30%
Input:
Bayesian network is represented as a list of nodes. Each node is represented as a list in the following order:
name: string
parent names: a list of strings. Can be an empty list
cpt: a conditional probability table represented as an array. Each entry corresponds to the conditional probability that the variable corresponding to this node is true. The rows are ordered such that the values of the node’s parent variable(s) are enumerated in the traditional way. That is, in a table, the rightmost variable alternates T, F, T, F, …; the variable to its left T, T, F, F, T, T, F, F, …; and so on.

Answers

In this assignment, the implementation of two approximate inference methods for Bayesian networks, namely rejection sampling and Gibbs sampling, is required.

Rejection sampling carries 70% weightage in grading, while Gibbs sampling carries 30% weightage.  The assignment focuses on implementing two methods for approximate inference in Bayesian networks: rejection sampling and Gibbs sampling. Rejection sampling is a simple method that involves sampling from the joint distribution and then accepting or rejecting the samples based on certain conditions.

On the other hand, Gibbs sampling is a Markov Chain Monte Carlo (MCMC) method that iteratively samples from the conditional distribution of each variable given the values of its neighbors. Gibbs sampling provides a more efficient way to approximate the joint distribution. The implementation of Gibbs sampling will carry 30% weightage in the grading.

The input for the assignment is provided in the form of a Bayesian network, which is represented as a list of nodes. Each node contains information such as its name, parent names (if any), and a conditional probability table (CPT). The CPT represents the conditional probabilities of the node given its parents. The ordering of rows in the CPT follows the enumeration of parent variable values in a traditional way.

can_hike_to(List[List[int]], List[int], List[int], int) -> bool The first parameter is an elevation map, m, the second is start cell, s which exists in m, the third is a destination cell, d, which exists in m, and the forth is the amount of available supplies. Under the interpretation that the top of the elevation map is north, you may assume that d is to the north-west of s (this means it could also be directly north, or directly west). The idea is, if a hiker started at s with a given amount of supplies could they reach d if they used the following strategy. The hiker looks at the cell directly to the north and the cell directly to the south, and then travels to the cell with the lower change in elevation. They keep repeating this stratagem until they reach d (return True) or they run out of supplies (return False).

Assume to move from one cell to another takes an amount of supplies equal to the change in elevation between the cells (meaning the absolute value, so cell's being 1 higher or 1 lower would both cost the same amount of supplies). If the change in elevation is the same between going West and going North, the hiker will always go West. Also, the hiker will never choose to travel North, or West of d (they won’t overshoot their destination). That is, if d is directly to the West of them, they will only travel West, and if d is directly North, they will only travel North.

Read the passage below and answer the question that follows:Seneca Falls: Common GroundBy Andrea BrecheenThe Seneca Falls Convention of 1848 was the single-most important event of the early women's suffrage movement. The suffrage movement grew out of centuries of shameful and unfair treatment of women. At the time of the Convention, women did not have the right to vote or serve on juries, and many women were unable to inherit property. In the decades leading up to the Convention, a small group of women began to rebel against these injustices. Suffrage originated from women's participation in the anti-slavery and temperance movements.The Seneca Falls Convention was the first conference dedicated to women's rights. The Convention was organized by two female abolitionists, Elizabeth Cady Stanton and Lucretia Mott. Lucretia Mott was an eloquent Quaker social reformer. Mott had previously been denied the right to speak at an anti-slavery conference in London after the men voted to exclude women from participating. Unlike many women of her time, Elizabeth Cady Stanton received a formal education. At the age of 16, Stanton studied mathematics, Latin, and Greek, demonstrating her keen abilities by mastering the subjects alongside boys of her own age.Coming together to support the suffrage movement, Mott and Stanton organized the Convention in Seneca Falls, NY in July of 1848. During the six-day meeting, Stanton presented the Declaration of Sentiments, a document she based on the Declaration of Independence. In the Declaration, she so elegantly wrote, "We hold these truths to be self-evident: that all men and women are created equal." The Declaration included a list of grievances detailing the treatment of women. The Declaration was signed by sixty-eight women and thirty-two men.Following the Convention, in 1848 the New York State Assembly passed the Married Women's Act. This act protected property that women brought into or earned during marriage.Read the passage. Which sentence best represents a fact about Elizabeth Cady Stanton detailed in the text?
