Answer:

Create the student class object which inherit the printinfo() from the abstract class People

Explanation:

Classes in object-oriented programming are blueprints of a defined type of data structure.

An object of an abstract class cannot be instantiated. So, the People class in question, is only inherited by the Student class which able to use the define printinfo() method.

Answer:

Check the explanation

Explanation:

We will be arranging the plaintext in a 4 * 4 matrix (which is a rectangular shaped group of symbols, numbers, or expressions, that are arranged in columns and set rows For example, the dimension of the matrix we will be using to explain the above question is 4 × 4, because there are four rows and four columns.) in the step by step explanation below.

Declare a struct named PatientData that contains two integer data members named heightInches and weightPounds. Sample output for

boyakko [2]

Answer:

struct PatientData{

int heightInches, weightPounds;

};

Explanation:

In order to declare the required struct in the question, you need to type the keyword struct, then the name of the struct - PatientData, opening curly brace, data members - int heightInches, weightPounds;, closing curly brace and a semicolon at the end.

Note that since the object - lunaLovegood, is declared in the main function, we do not need to declare it in the struct. However, if it was not declared in the main, then we would need to write lunaLovegood between the closing curly brace and the semicolon.

user_tweet = input()

decoded_tweet = user_tweet.replace('TTYL', 'talk to you later')

print("This is the decoded tweet: ")

print(decoded_tweet)

Explanation:

In the program the replace() module was used to replace 'TTYL' with 'talk to you later.'

Attached is the screenshot of the output.

A computer has 4 GB of RAM of which the operating system occupies 512 MB. The processes are all 256 MB (for simplicity) and have

Afina-wow [57]

Answer:

$1-p^{14} = 0.99$

$p^{14}= 0.01$

$p =(0.01)^{1/14}= 0.720$

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %

Explanation:

Previous concepts

Input/output operations per second (IOPS, pronounced eye-ops) "is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD)"

Solution to the problem

For this case since we have 4GB, but 512 MB are destinated to the operating system, we can begin finding the available RAM like this:

Available = 4096 MB - 512 MB = 3584 MB

Now we can find the maximum simultaneous process than can use with this:

$\frac{3584 MB}{256 MB/proc}= 14 processes$

And then we can find the maximum wait I/O that can be tolerated with the following formula:

$1- p^{14}= rate$

The expeonent for p = 14 since we got 14 simultaneous processes, and the rate for this case would be 99% or 0.99, if we solve for p we got:

$1-p^{14} = 0.99$

$p^{14}= 0.01$

$p =(0.01)^{1/14}= 0.720$

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %
