Question 12 . In the slides and videos, I went over recursive definitions for full binary trees, the number of nodes of a full binary tree, and the height of a full binary tree. Recall that full binary trees allow nodes with 0 children and nodes with 2 children, and that is all. In a full binary tree, if a node has 0 children, it is called external. If it has 2 children, it is called internal. (a) Write a recursive definition for the number of external nodes in a full binary tree. Start by determining the number of external nodes in a base case full binary tree. Then consider joining two full binary trees and think about how many external nodes there are in the resulting tree with respect to the number of external nodes in the smaller trees. (b) Write a recursive definition for the number of internal nodes in a full binary tree. Start by determining the number of internal nodes in a base case full binary tree. Then consider joining two full binary trees and think about how many internal nodes there are in the resulting tree with respect to the number of internal nodes in the smaller trees. (c) Look at several examples of full binary trees. You can either draw these yourself or look at the examples in the textbook/slides. For each one, count up the number of internal nodes and the number of external nodes until you notice a pattem and can fill in the following conjecture: For all full binary trees T,e(T)= (Fill in with something in terms of i(T).) (d) Use structural induction and the definitions you wrote in (a) and (b) to prove the conjecture in (c).

Project managers should carefully consider the potential risks and challenges before making such a decision.

Project management can be a complex process, and as such, it is important that the project manager is careful when making certain decisions regarding the project, especially when it comes to reducing project duration by adding resources. In most cases, the decision to add resources can be made in a bid to reduce the time spent on the project. However, this decision should not be taken lightly, as there are certain risks and challenges that come with adding resources to reduce project duration.Firstly, adding resources can often lead to increased project costs. This is because when additional resources are added to the project, they will need to be compensated for their work. As a result, the cost of the project will increase, which can lead to budget overruns. Therefore, before making the decision to add resources to the project, the project manager should carefully consider the potential impact on the project budget.Secondly, adding resources can also lead to communication issues. When new team members are added to the project, it may be difficult to ensure that everyone is on the same page. This can lead to misunderstandings, errors, and delays. Therefore, the project manager should take steps to ensure that all team members are communicating effectively and working towards the same goals.Finally, adding resources can also lead to a decrease in the quality of the work. This is because when additional resources are added, they may not be as familiar with the project and its objectives. As a result, the quality of their work may not be as high as that of the original team members. Therefore, the project manager should be cautious when adding resources to ensure that the quality of the work remains high.In conclusion, the decision to add resources to reduce project duration should not be taken lightly. Project managers should carefully consider the potential risks and challenges before making such a decision.

The shared secret key is 8

To find the shared secret key using the Diffie-Hellman Key Exchange algorithm, Alice and Bob must each perform the following steps:

1. Alice selects a random number, a, and calculates A = g^a mod p
2. Bob selects a random number, b, and calculates B = g^b mod p
3. Alice sends A to Bob, and Bob sends B to Alice
4. Alice calculates the shared secret key as K = B^a mod p
5. Bob calculates the shared secret key as K = A^b mod p

Using the given values:

- p = 11 (prime)
- g = 5 (generator)
- Alice's random secret number is a = 3
- Bob's random secret number is b = 7

Alice calculates A = g^a mod p = 5^3 mod 11 = 8
Bob calculates B = g^b mod p = 5^7 mod 11 = 2

Alice sends A = 8 to Bob, and Bob sends B = 2 to Alice.

Alice calculates the shared secret key as K = B^a mod p = 2^3 mod 11 = 8
Bob calculates the shared secret key as K = A^b mod p = 8^7 mod 11 = 8

Therefore, the shared secret key is 8, which can be used to encrypt a message using a symmetric encryption algorithm.

Answer:

require direct line-of-sight scanning.

Explanation:

Unlike radio frequency identification (RFID) tags, bar codes require direct line-of-sight scanning. Meaning you need a device that can scan the bar code and the scanner needs to be directly pointing at the barcode without anything in the way. This is because bar codes work by embedding the information in a design of lines that need to be scanned to retrieve the information. If anything gets in the way it interrupts the scanning process and the data is not correctly transmitted. RFID tags on the other hand do not need a direct line of sight since the information is transferred through radiofrequency. This allows the data to be transferred without a line of sight and at a distance of up to 300ft.

The analogy presented is "Frugality: Stingy." Frugality refers to the quality of being economical or sparing in the use of resources, especially money.

It implies a conscious effort to avoid waste and unnecessary expenses. The word "stingy" describes someone who is unwilling to spend money or resources, often being excessively cautious or tight-fisted.

To determine the correct answer, we need to identify a word pair that exhibits a similar relationship to the given analogy. Among the options provided, the most suitable choice is:

Warmth; generous

This option presents a similar relationship to the original analogy. "Warmth" can be associated with being generous, indicating a willingness to share and provide comfort or assistance to others. This aligns with the idea of frugality, as someone who is frugal may still be generous and warm-hearted.

The other options do not exhibit the same relationship as frugality and stingy. "Resolution; whimsical," "Reflection; thoughtful," "Pride; haughty," and "Jauntiness; morose" do not capture the concept of being economical or sparing in the use of resources.

The probability that a person is denied access, given that they are authorized, can be calculated using Bayes' theorem. We need to find the probability of being denied access and being authorized, and divide it by the probability of being authorized.

First, we calculate the probability of being denied access and being authorized. This is equal to the probability of being denied access, given that they are authorized, multiplied by the probability of being authorized.
The probability of being denied access, given that they are authorized, can be calculated as (3/100) * (1/99) = 0.000303.
The probability of being authorized is given as 99%.
Now we can calculate the conditional probability of being denied access, given that they are authorized, by dividing the probability of being denied access and being authorized by the probability of being authorized.
Therefore, the probability that a person is denied access conditional on being authorized is 0.000303 / 0.99 = 0.003.
The probability that a person is denied access conditional on being authorized is 0.003.
