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. On the flipside, as a business owner Excel is a handy tool for tracking expenses. Very customizable, quick and easy to understand.

Explanation:

HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.

A website refers to the collective name used to describe series of web pages linked together with the same domain name.

On the other hand, a webpage is the individual HTML document (single page) that makes up a website with a unique uniform resource locator (URL).

A bookmark can be defined as a placeholder or saved shortcut for a webpage and for future reference. Thus, it avails an end user the ability to quickly access a bookmarked webpage by automatically directing the web browser to the webpage.

Basically, the steps for creating a bookmark are;

1. The insertion point of the webpage should be placed at the point where the bookmark should appear.

2. Click the "INSERT" tab.

3. In the "LINKS" group, click "Bookmark"

4. When a dialog box opens, the bookmark should be named with a specific title, and then click "ADD"

5. To see bookmarks within the HTML document, you should go to Backstage view and click on "Options"

6. In ADVANCED, select Show Bookmarks to have them appear as a locked cursor within the HTML document.

The eight primitive data types in Java include:

byte , short , int , long , float , double , boolean and char.

By size of datatype we mean the amount of memory the data type occupies. For a 32-bit processor/CPU,

The size of int data type(with whole numbers from -2,147,483,648 to 2,147,483,647) in Java is 4 bytes

The size of byte data type is 1 byte

The size of short data type is 2 bytes

The size of long data type is 8 bytes

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.

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.

JUST DID IT (Edge 2021)

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")

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 :

1. We should always take permission from those who are being recorded. It is not right to shoot others without their permission. It is against the right to privacy.

2. We should record audio at about 44.1 kHz/16 bit in an uncompressed wave format.

3. A High quality MP3 (192 kbps or higher) is often accepted due to the limitations of a recorder or for a storage space.

The MP3 recordings are considered as the best option for certain recorders  and when the storage space is severely limited. It produces a good quality recording.
