Answer:

Business communications tools are widely used and the world is becoming increasingly digital so not having those skills will hinder you.

Explanation:

Many jobs require knowledge of Microsoft tools as a qualification. By not having that expertise, I will be viewed as less qualified for a position and may be passed up for job. In corporate America, presentations are a staple and Microsoft PowerPoint is the primary software. If I deliver a poor presentation due to inexperience, I will make myself look bad and as a result get a bad quarterly review and possibly stunted any future promotions.

Digital recording may be defined as the preservation of an audio or some visual signals like the series of a binary numbers which can be stored on a magnetic tape or on an optical disc or some other digital storage media.

Some of the best practices for doing digital recording are :

Ex: If the input is:

e

the output is:

earn

Note: Using a pre-defined string function, the solution can be just one line of code.​

Answers

Answer:

The program in Python is as follows:

myStr = input()

pos = int(input())

chrr = input()

myList=[]

myList[:0]=myStr

myList[pos] = chrr

myStr =""

for i in myList:

   myStr+=i

print(myStr)

Explanation:

This gets input for the string

myStr = input()

This gets input for the character position

pos = int(input())

This gets input for the incoming character

chrr = input()

Create an empty list

myList=[]

Convert the string to a list

myList[:0]=myStr

Replace the character

myList[pos] = chrr

Empty the string

myStr =""

Get the new string

for i in myList:

   myStr+=i

Print the new string

print(myStr)

Following are the C++ program to replace the first index value of the string.

Program Explanation:

Defining header file.Defining the main method.Inside the main method three variable "Sval, Spos, Subchar" is declared in which "string, int, and char".After input variable value a string variable is declared with the at (method), which replaces the first index value with the character value.After replacing the first index value that is "0" use the prints method that prints its value.

Program:

#include <iostream>//header file

using namespace std;

int main() //main method

{

 string Sval;//defining string variable

 int Spos;//defining integer variable

 char Subchar;//defining char variable

 cin>>Sval>>Spos>> Schar;//input value

 Sval.at(Spos)  =  Subchar; //using string variable that replaces the first index value with the character value

 cout << Sval << endl;//printing the replaced value

 return 0;

JUST DID IT (Edge 2021)

Q.No.2. A study of the effect of smoking on sleep patterns is conducted. The measure observed is the time, in minutes, that it takes to fall asleep. These data are obtained: [3] Smokers:69.3 56.0 22.1 47.6 53.2 48.1 52.7 34.4 60.2 43.8 23.2 13.8 Non Smokers: 28.6 25.1 26.4 34.9 28.8 28.4 38.5 30.2 30.6 31.8 41.6 21.1 36.0 37.9 13.9

Answers

Answer:

(a) [tex]\bar x_1 = 43.7[/tex]     [tex]\bar x_2 = 30.25[/tex]

(b) [tex]\sigma_1 = 16.93[/tex]    [tex]\sigma_2 = 7.14[/tex]

(c) Smoking increases the time to fall asleep

Explanation:

Solving (a): The sample mean of each group

Mean is calculated as:

[tex]\bar x = \frac{\sum x}{n}[/tex]

So, we have:

Smokers

[tex]n_1= 12[/tex] and

[tex]\bar x_1 = \frac{69.3 +56.0+ 22.1 +47.6+ 53.2+ 48.1+ 52.7 +34.4+ 60.2 +43.8 +23.2 +13.8}{12}[/tex]

[tex]\bar x_1 = \frac{524.4}{12}[/tex]

[tex]\bar x_1 = 43.7[/tex]

Non Smokers

[tex]n_2 = 15[/tex] and

[tex]\bar x = \frac{28.6 +25.1 +26.4 +34.9 +28.8 +28.4 +38.5 +30.2 +30.6 +31.8 +41.6 +21.1 +36.0 +37.9 +13.9}{15}[/tex]

[tex]\bar x_2 = \frac{453.8}{15}[/tex]

[tex]\bar x_2 = 30.25[/tex]

Solving (b): The standard deviation of each group

This is calculated as:

[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]

For smokers

[tex]n_1= 12[/tex]

So:

[tex]\sigma_1 = \sqrt{\frac{(69.3 -43.7)^2+(56.0-43.7)^2+..........+(13.8-43.7)^2}{12-1}}[/tex]

[tex]\sigma_1 = \sqrt{\frac{3152.04}{11}}[/tex]

[tex]\sigma_1 = \sqrt{286.5491}[/tex]

[tex]\sigma_1 = 16.93[/tex]

For non-smokers

[tex]n_2 = 15[/tex]

So:

[tex]\sigma_2 = \sqrt{\frac{(28.6 -30.25)^2+(25.1 -30.25)^2+..........+(13.9 -30.25)^2}{15-1}}[/tex]

[tex]\sigma_2 = \sqrt{\frac{713.2575}{14}}[/tex]

[tex]\sigma_2 = \sqrt{50.9469}[/tex]

[tex]\sigma_2 = 7.14[/tex]

Solving (c): Impact of smoking on time to sleep

In (b), we have:

[tex]\sigma_1 = 16.93[/tex] --- smokers

[tex]\sigma_2 = 7.14[/tex] --- non-smokers

Smokers have larger standard deviation (i.e. large variability) than non-smokers. This means that smokers require more time to fall asleep.

Explanation:

Write a program that takes as input: - the current hour - the number of hours to add and outputs the new hour. For example, if the inputs are 2 (as the current hour) and 51 (as the number of hours to add), your program should output the answer from part (a) of this problem. Note that your program should always output an integer between 1 and 12. We will get you started with this program with the two lines that gather the input from the user. You'll need to write the rest.

Answers

Answer:

The program in Python is as follows:

cTime = int(input("Current Hour: "))

while(cTime <1 ):

   cTime = int(input("Current Hour: "))

aTime = int(input("Additional Hours: "))

while(aTime <0):

   aTime = int(input("Current Hour: "))

tTime = cTime + aTime

tTime%=12

print("New:",tTime,"hours")

Explanation:

This gets input for current time

cTime = int(input("Current Hour: "))

The following ensures that the user enters a time greater than 0

while(cTime <1 ):

   cTime = int(input("Current Hour: "))

This gets input for additional time

aTime = int(input("Additional Hours: "))

The following ensures that the user enters a positive time

while(aTime <0):

   aTime = int(input("Current Hour: "))

This calculate the new hours

tTime = cTime + aTime

This gets the hour equivalent between 1 and 12

tTime%=12

This prints the new hour

print("New:",tTime,"hours")
