Based on the given pruning table, the tree with a level of 2 is the best-pruned tree. The pruning table contains four columns: Level, CP, Num Splits, and Relative Error.

The level column contains the tree's depth or number of splits, while the CP column contains the pruning threshold. The Num Splits column contains the number of splits in the tree, and the Relative Error column contains the validation error. The goal of pruning is to simplify the decision tree by removing nodes that are not essential for classification. In decision tree pruning, the tree is initially grown to a substantial size, and then nodes are removed to reduce overfitting. When pruning decision trees, the goal is to locate a subtree that would be more straightforward and give the same or nearly the same prediction. The best-pruned tree is the one that achieves the smallest validation error after pruning. Based on the table given above, the tree with a level of 2 is the best-pruned tree. This tree has a relative error of 0.0612, which is the smallest value among the other trees.

Therefore, the best-pruned tree is the one with a level of 2. Here is the formatted HTML version of the answer:

Level     CP       Num Splits      Relative Error

1          0.500    1.00   1.17

2         0.0507  3.00  0.441

3         0.0020  6.00  0.060

4         0.100     9.00   0.030

Therefore, the answer is the tree with a level of 2.

The protocol that allows the receiver to send individual ack for each packet is Option B. The Transport-layer protocol. When TCP and UDP (transport-layer protocols) are used, a number of packets may be sent to transmit a single message across the network.

Each packet has its own header, containing the source and destination IP addresses, as well as the data contained in that packet.

Protocols: Protocols are a set of rules that govern how data is transferred across a network.

Layer: In computer networks, there are seven layers, each with its own unique set of responsibilities. These layers aid in the organization and delivery of data.

Packets: Packets are smaller pieces of data that are transmitted over the network, and they are used to make data transfer more efficient. Packets contain the information required to transmit data over the network.

Answer:

See below.

Explanation:

If Violet wants to apply the tiles to the scene easily, she will need to create and work from a Tilemap. A Tilemap is a GameObject that stores and handles Tile Assets for creating 2D levels. It transfers the required information from the Tiles placed on it to other related components such as the Tilemap Renderer and the Tilemap Collider 2D.

To create a default (rectangular) Tilemap, Violet can go to GameObject > 2D Object > Tilemap. She can then use the Tile Palette window to paint Tiles onto her Tilemap.

The other options are not relevant for applying tiles to the scene. A RigidBody is a component that allows a GameObject to be affected by physics forces. A Spritesheet is an image file that contains multiple smaller images of game sprites. A Paint Swatch is a sample of color used for painting walls or other surfaces.

The boolean expression is executed before each execution of the loop body in a do-while loop. The statement is true.

A do-while loop is a loop statement that performs its first iteration without verifying the loop control variable or the condition tested by the while loop. A do-while loop can be used to repeat a block of statements until a certain condition is met.

The while loop is evaluated before the loop body is executed in a while loop. If the condition is false, the loop body is never executed. A do-while loop is distinct from a while loop in that the loop body is executed at least once, and then the condition is tested. The loop body will continue to execute as long as the condition is true. In a do-while loop, the statement(s) are executed until the condition is no longer true.

The code for a do-while loop in Java is as follows:

do{ // loop body} while(condition);

The loop body is executed first, and then the condition is checked. If the condition is false, the loop is exited. If the condition is true, the loop body is executed again, and the condition is checked again. The loop is terminated when the condition is false.

The sum variable can be used within the scope of the if statement's false path. This means that the variable can only be used within the statement that contains it, which is the statement 'int sum = 0'. It cannot be accessed from outside the if statement's false path.

In other words, the sum is a local variable, which means it is only accessible within the scope of the if statement's false path. This is because when a variable is declared in an if statement, it is only accessible within the scope of that if statement. Any code that comes after the if statement cannot access the sum variable.

For example, if the false path of the if statement is the following:

if (false) {
   int sum = 0;
   // Do something with sum
}
// Code after the if statement
Then, the code after the if statement cannot access the sum variable, as it was declared within the scope of the if statement's false path.

To conclude, if an if statement's false path contains the statement int sum =0;, then the sum variable can only be used within the scope of the if statement's false path.

The purpose of the three-level database architecture is to support data independence.

Data independence is the ability of a system to be unaffected by changes in the physical structure of the data, such as the addition, deletion, or relocation of data. The three levels of database architecture are the physical level, the logical level, and the view level.

At the physical level, the data is stored in a specific format. This is the lowest level of the database structure. It deals with how the data is actually stored and retrieved.

At the logical level, the data is organized in a way that makes it easy for users to understand and use. This level allows for data to be organized in a way that makes sense to users, without having to worry about the details of the physical structure.

At the view level, the data is organized in a way that allows for data independence. This means that changes to the physical structure of the data can be made without having to update the logical structure of the data. This allows for more flexibility when making changes to the data.

True, one goal of an agile user story is the prevention of misunderstandings or misinterpretations of user requirements because a user story outlines a feature or functionality that a business user requires to complete a specific task.

A user story is a fundamental Agile artifact that captures requirements from an end-user perspective.  The narrative of a user story is intended to elicit a dialogue between the development team and the end user. A user story should be unambiguous, clear, and comprehensible. It should also be able to promote a dialogue between the developer and the end-user, allowing both parties to communicate about the project's priorities and goals.

In an Agile environment, developers use user stories to write code iteratively. This means that developers receive input on user requirements regularly and that they can test their work in small chunks at a time.

In Agile, the objective is to reduce the length of development cycles so that the development team can react promptly to user feedback. Agile emphasises communication and collaboration between team members, both within the development team and with end-users. Agile development aims to satisfy end-users by prioritising the most critical requirements and frequently updating software during development.

A user story is a narrative that communicates a feature's value or functionality from the end-users viewpoint. The purpose of an agile user story is to align development work with user requirements. The purpose of an agile user story is to describe an end-users journey from the start to the end of a task or a process. The objective of the user story is to elicit a discussion with the end-user about their needs and requirements.

The objective of the discussion is to develop a better understanding of what the end-user needs from the software project. This dialogue enables developers to make better decisions about prioritising features and determining project scope. To summarise, one of the primary goals of an agile user story is the prevention of misunderstandings or misinterpretations of user requirements.

Agile user stories aim to capture end-users' requirements and use them to guide development work. This ensures that developers deliver software that meets end-users' needs and delivers value to the business.
