As the first step, load the dataset from airline-safety.csv by defining the load_data function below. Have this function return the following (in order):
1. The entire data frame
2. Total number of rows
3. Total number of columns
def load_data():
# YOUR CODE HERE
df, num_rows, num_cols

Answers

Answer 1

Answer:

import pandas as pd

def load_data():

df = pd.read_csv("airline-safety.csv')

num_rows = df.shape[0]

num_cols = df.shape[1]

return df, num_rows, num_cols

Explanation:

Using the pandas python package.

We import the package using the import keyword as pd and we call the pandas methods using the dot(.) notation

pd.read_csv reads the csv data into df variable.

To access the shape of the data which is returned as an array in the format[number of rows, number of columns]

That is ; a data frame with a shape value of [10, 10] has 10 rows and 10 columns.

To access the value of arrays we use square brackets. With values starting with an index of 0 and so on.

The row value is assigned to the variable num_rows and column value assigned to num_cols

Suppose a program written in language L1 must be executed on a machine running a program running in language L0. What important operation must take place

Answers

Question Completion with Options:

a. Translation of the entire L1 program into L0 code

b. Translation of the L0 program into L1 code

c. Creation of a language L3 that interprets L0 instructions

d. Interpretation of each L1 statement using L0 code as the L1 program is running.

Answer:

The important operations that must take place in this scenario are:

a. Translation of the entire L1 program into L0 code

d. Interpretation of each L1 statement using L0 code as the L1 program is running.

Explanation:

Translation enables decoding to take place.  This means that the L1 program is decoded into a language that the L0 program can understand and execute.  Without this translation, the higher level language of L1 will not be understood by the machine language of the L0 programs.  Translation of a code creates a shared understanding, thereby easing program execution.  Code translation is simultaneously accompanied by interpretation.

You are to calculate the property tax for tax payers. You will ask the county tax clerk if they want to run the program and initiate a loop that runs the program if the county clerk inputs a 1. When the county clerk chooses to run the program, you will ask the county tax clerk to input the lot number and assessed value of the house. Each property is taxed at a rate of 5% of the assessed value. The program will end when the county clerk enters a value of 0 when prompted by your program to either run the program again or quit. Use a while loop to validate the lot number to make sure that it falls between the range of 0 and 999999. When the clerk enters an invalid lot number, display a message that echoes the invalid number entered, and a reminder of the value range of numbers for a lot number. You are to print the lot number, assessed value, and property tax. After the program ends, display the total assessed values, and property taxes calculated, and average property tax

Suppose you have a stack ADT (i.e., an Abstract Data Type that includes operations to maintain a stack. Design a flowchart or suitable logical diagram to show you could implement a queue’s enqueue and dequeue operations using two stacks, stack 1 and stack 2.

Answers

Answer:

One approach would be to move all items from stack1 to stack2 (effectively reversing the items), then pop the top item from stack2 and then put them back.

Assume you use stack1 for enqueueing. So enqueue(x) = stack1.push(x).

Dequeueing would be:

- For all items in stack1: pop them from stack1 and push them in stack 2.

- Pop one item from stack2, which will be your dequeue result

- For all items in stack2: pop them from stack2 and push them in stack 1.

Company A has a project plan for a new product under development. The product will be one of many released in the coming year. The plan, if disclosed, might give Company A's competition a market advantage. Which ISO 27002 classification level is most likely assigned to this document?
a) Public Documents
b) Proprietary
c) Highly Confidential
d) Top Secret

Answers

Answer:

Company A

The ISO 27002 classification level that is most likely assigned to this document is:

b) Proprietary

Explanation:

The ISO 27002 classification levels adopted by commercial organizations are Restricted (top secret is preferred in government circles), Confidential, Internal (or proprietary), and Public. Since the new product is under development, one of many, and most likely known to the project team, the project plan will be classified as Proprietary.  Company A designates this document as Proprietary or Internal to show that disclosure of the information to its competitors is not allowed.  This level of classification shows that Company A can establish intellectual property rights over the document.

I connected to an external hard drive to transfer some photos from my vacation. When I try to drag the photo, it bounces right back and does not transfer. What is the likely cause of this issue?

a. hard drive is full

b. photos were taken in a different country

c. USB port is broken

d. the file structure of the 2 hard drives are not compatible

Answers

Your answer is D.

Hope this helps and if you could answer the question I just uploaded titled giving brainliest that would be great. Basically, what you have to do is research why the book titled the list of things that will not change and explain why it’s your favorite book based on the message it tells you! Go to my profile and go to questions.

The answer is D, What is the likely cause of this issue is that the file structure of the two hard drives are not compatible.

The file structure or file system, of a hard drive, tells the disk how to read, write and store information on the drive. Some file systems do not allow the disk to store any files and often do not display error messages. If we try to drag a file onto a hard drive with this kind of file structure, the action would simply not be performed. This can be fixed by formatting the disk partition into a new file system.

Option B states that the issue may be that the photos were taken in a different country. This is not the cause of the problem because regardless of where the pictures are taken, they are all stored in common formats such as:

JPEGPNGJFIF

Any external hard drive capable of storing images will have the ability to receive files in these formats as well as many other image formats. For this reason, option B is False.

The question states that you were able to connect the external Hard drive and drag files onto it, though unsuccessfully. This tells us that the USB port is working as intended, if it were not working, it would not display the Hard drive onto the computer and we would not be able to drag files to it. Therefore, option C is false

Insufficient Hard drive storage space is a common issue in not being able to transfer files between hard drives. However, if this were the case, the user would be shown a message displaying the error. The message may look like:

"Insufficient space on the disk.""The Disk is full.""Not enough memory to complete this action"

The exact wording may vary depending on the operating system in use. Since the question states that the files simply "bounces back" without an error message displaying, we can infer that option A is false.
