For each example given below, identify and write the type of data out of four choices:
Nominal data, Ordinal data, Interval data, and Ratio data. Mark N, O, I, or R
Salary, Nationality, Grade (A,B,C,D), Temperature
The type of data for each example is:
Salary: Ratio data (R)
Nationality: Nominal data (N)
Grade (A, B, C, D): Ordinal data (O)
Temperature: Interval data (I)
Salary: Ratio data (R) - Salary is a type of quantitative data that can be measured on a continuous scale. It has a meaningful zero point, allowing for meaningful comparisons and calculations. For example, if one person earns $50,000 and another person earns $100,000, we can say that the second person earns twice as much as the first person.
Nationality: Nominal data (N) - Nationality is a categorical variable that cannot be ranked or quantified. It is a form of qualitative data that represents different categories or groups. For example, someone can be of American, British, or Indian nationality, but we cannot assign a numerical value or order to these categories.
Grade (A, B, C, D): Ordinal data (O) - Grades are categorical variables that have a specific order or ranking. Although the actual difference between grades may not be consistent, we can still rank them from highest to lowest. For example, A is higher than B, B is higher than C, and so on.
Temperature: Interval data (I) - Temperature is a quantitative variable that can be measured on a continuous scale. However, it lacks a meaningful zero point. The interval between temperatures is consistent, but zero degrees does not indicate the absence of temperature. For example, the difference between 20 and 30 degrees Celsius is the same as the difference between 30 and 40 degrees Celsius, but 0 degrees Celsius does not mean "no temperature."

How are the waterfall and agile methods of software development similar?
The waterfall and agile methods of software development are similar in that they both aim to develop software in an organized and efficient manner. However, they differ in the approach they take to achieve this goal.
The waterfall method is a linear, sequential method of software development. It follows a defined process with distinct phases, such as requirements gathering, design, implementation, testing, and maintenance. Each phase must be completed before the next phase can begin, and changes to the software are not allowed once a phase is completed.
On the other hand, Agile method is an iterative and incremental approach to software development. It emphasizes on flexibility, collaboration, and customer satisfaction. Agile method encourages regular inspection and adaptation, allowing for changes and improvements to be made throughout the development process. Agile methodologies, such as Scrum and Kanban, follow an incremental approach, where the software is developed in small chunks called iterations or sprints.
Both Waterfall and Agile approach have their own advantages and disadvantages and are suitable for different types of projects and teams. It is important to choose a method that aligns with the specific needs and goals of the project and the team.

/* missing code */
System.out.print(volume);
Which of the following can be used to replace /* missing code */ so that the code segment works as intended?
I. double baseArea = pi * r * r;double volume = baseArea * h;
II. double volume = pi * r * r;volume = volume * h;
III. double volume = pi * r * r * h;
a. I only
b. III only
c. I and III only

Answer:
The answer is "Option e".
Explanation:
In this question we calculating the volume of a cylinder, that's formula is:
\(\boxed{\text{Volume}= \pi \times r^2 \times h}\)
In the above, we use π that's value is 3.14 or \(\frac{22}{7}\) and "r and h" is input by the user. In the given choices all were correct it calculates the volume, that can be defined as follows:
In choice 1, The double variable "baseArea" is declared, which first calculates \(\pi \cdot r^2\) value then multiply the h value and store it into the "volume" variable.In choice 2, The double variable "volume" is declared, which first calculates \(\pi \cdot r^2\) value then multiply the h value and store it into the "volume" variable. In choice 2, The double variable "volume" is declared, which directly calculates the volume value by the above-given formula.What are headings in HTML?

Write a program to convert centigrade to Kelvin. It should display value in centigrade and then the value in Kelvin just as you displayed squares in the previous question. The range to be followed for this conversion is from 50-100 degree celsius.
So, it should look like this:
1. Centrigrade: 50 --> Kelvin: 323.15
2. Centrigrade: 51 --> Kelvin: 324.15
3. Centrigrade: 52 --> Kelvin: 325.15

Explanation:
*The code is in Python.
Create a for loop that iterates from 50 to 100 (Note that the starting value is included, but the ending value is not included in the range method. That is why you need to write range(50, 101) to iterate from 50 to 100)
Convert the centigrade to kelvin using formula (Note that the degree variable represents the each centigrade degree from 50 to 100 and you need to add 273.15 to convert it to Kelvin)
