Answer:

For 9GB of data the user would pay $82 monthly!

Explanation:

To start off, our end goal is 9GB. We have the equation 9 = ? We can add up to our solutions with 1GB, 3GB, and 10GB. We can immediately rule out 10GB, since 9GB ≠ 10GB. To cost the least amount of money we can add up             3GB and 1GB = 4GB + 5GB = 9GB!

So, our equation is 3GB + 1GB + 5GB = 9GB, now lets figure out the cost!

                                $28 + $12 + $42 = $82

For 9GB of data the user would pay $82 monthly!

Answer:

Ambiguity.

Explanation:

Natural language of human beings are believed to be ambiguous, as it often required settings punctuation, and intonation to determine certain meanings correctly.

Also is the fact that natural language sometimes has more than one meaning for the same words.

Hence, one characteristic of natural languages that prevent them from being used as programming languages is AMBIGUITY.

The index value of the first element in a JavaScript array is zero

Explanation:

Required

Index of first JavaScript array element

Just like numerous programming languages, when an array is declared in JavaScript, the index of the array starts at 0.

Meaning that the first element of the JavaScript array is indexed 0

Say for instance, the array has 5 elements:

This is declared as:

var arrayname = Array(5);

The first of the 5 elements of the array starts at 0 while the last of the 5 elements would be at index 4.

The missing code segment is meant to initialize the variable minimum to the first list element.

The missing code is (d) numList[0]

From the question, we understand that the first line of the program should determine the smallest number in the list numList

To do this, we start by initializing the variable minimum to the first element of numList

This is done using the following code segment:

var minimum = numList[0]

Hence, the missing code segment is (d) numList[0]

Explanation:

BAM

To send an email to someone without revealing that person’s email address to others on the distribution list.

"Blind carbon copy" is referred to as BCC. BCC is a similar method to CC for forwarding copies of an email to additional recipients. When CC is used, a list of recipients is shown; when BCC is used, a list of recipients is not visible.

Because the other receivers won't be able to see that the email has been forwarded to another person, it is known as a blind carbon copy.

Carbon copy is referred to as a "CC" in email communication. When there was no internet or email, you had to sandwich a piece of carbon paper between the paper you were writing on and the paper you wanted to use as your copy in order to make a copy of the letter you were writing.

Therefore, To send an email to someone without revealing that person’s email address to others on the distribution list.

Answer:

The solution is implemented in python:

numnames = int(input("Number of Names: "))

nametitle = ["Surname: ","Firstname: ","Middlename: ","Middlename 2: "]

names = []

for i in range(numnames):

   name = input(nametitle[i])

   names.append(name)

print("Your fullname is: ",end=" ")

for i in names:

   print(i,end=" ")

Explanation:

This prompts user for number of names

numnames = int(input("Number of Names: "))

This lists the name titles in a list

nametitle = ["Surname: ","Firstname: ","Middlename: ","Middlename 2: "]

This initializes an empty list

names = []

The following for loop get names from the user

for i in range(numnames):

   name = input(nametitle[i])

   names.append(name)

The following instructions print the user fullnames

print("Your fullname is: ",end=" ")

for i in names:

   print(i,end=" ")

An example program in Python that asks the user for the number of names they have and then prompts them to enter each name.

It will then print their full name based on the names provided:

python

Copy code

num_names = int(input("How many names do you have? "))

names = []

for i in range(num_names):

   name = input("Enter name {}: ".format(i + 1))

   names.append(name)

full_name = " ".join(names)

print("Your full name is:", full_name)

In this program, we first ask the user to enter the number of names they have. The input is converted to an integer using int() since input() returns a string.

Then, we initialize an empty list names to store the names provided by the user.

Next, we use a for loop that iterates num_names times to ask the user for each name. The loop variable i starts from 0, so we add 1 to it when displaying the prompt using i + 1.

Inside the loop, we prompt the user to enter the name and append it to the names list. After the loop completes, we join all the names in the names list using the join() method with a space as the separator. This creates a single string representing the full name.

Answer:

The level of the signal is 353.85

Explanation:

Data rate determines the speed of the data transmission.

The data rate depends on the following factors

The data is transmitted either from a noiseless channel or a noisy channel.

The given quality of the channel in the question is noiseless.

Use the following formula to calculate the signal levels

Bit rate = 2 x bandwidth x [tex]Log_{2}[/tex] ( signal level )

where

Transmitted Data = 254 kbps = 254,000 bps

Bandwidth = 15 khz = 15,000 hz

Placing values in the formula

254,000 = 2 x 15,000 x [tex]Log_{2}[/tex] ( L )

254,000 = 30,000 x [tex]Log_{2}[/tex] ( L )

254,000 / 30,000 = [tex]Log_{2}[/tex] ( L )

8.467 = [tex]Log_{2}[/tex] ( L )

L = [tex]2^{8.467}[/tex]

L = 353.85 levels

Answer:

In any case, binary search can be used to solve more extensive scope of problem, for example, finding the next smallest or next-biggest element in an array comparative with the target regardless of whether it is present or missing in the array.

Explanation:

In computer science, binary search, otherwise called logarithmic search, is a search calculation that finds the position of an objective incentive inside an arranged array. Binary search compares  the  target value to the center component of the array. In the event that they are not equivalent, the half in which the value can't lie is dispensed with and the search proceeds on the other half, again taking the center value to contrast with the target value, and continues this until the target value is found. On the off chance that the search ends with the other half being empty, the target value isn't in the array.

Binary search is quicker than linear search aside from small arrays. Nonetheless, the array should be arranged first to have the option to apply  binary search. There are particular data structures intended for quick looking, for example, hash tables, that can be looked through more effectively than binary search.

When ordering a quadruple-shot latte, which contains four shots of espresso, you can also use the word quadruple to signify “four times as many.” The suffix quadric-, which means “four,” is the source of the Latin root quadruple, which means “create fourfold.”
