A group consists of 10 kids and 2 adults. On a hike, they must form a line with an adult at the front and an adult at the back.

blsea [12.9K]

Answer:

b. 2.9!

Explanation:

There are is a mistake in the question.

Suppose the group consist of 10 kids and 2 adults, the number of ways in which they can form the line is:

= 2! 10!

= 2× 1× 10!

= 2.10!

But since that is not in the given option.

Let assume that the group consists of 9 kids and 2 adults, the number of ways in which they can form the line is:

No of ways the kids can be permutated = 9 ways

No of ways the adult can be permutated = two ways.

Thus; the number of ways in which they can form the line = 2! 9!

= 2 × 1× 9!

= 2.9!

SummaryIn this lab, you complete a partially written C++ program that includes a function named multiplyNumbers() that multiplie

Maru [420]

Answer:

Declare the method prototype using:

void multiplyNumbers(int x, int y,int &product);

Call the function using:

multiplyNumbers(num1, num2,product);

Lastly, the method is as follows:

void multiplyNumbers (int x, int y,int &product) {

product = x * y;

return; }

Explanation:

Declare the method prototype using

void multiplyNumbers(int x, int y,int &product);

Call the function using

multiplyNumbers(num1, num2,product);

The method is as follows; the & written in front of product implies that product is passed by reference

void multiplyNumbers (int x, int y,int &product) {

This calculate the product

product = x * y;

This returns nothing

return; }

What are the network topologies? Advantages and disadvantages.

s344n2d4d5 [400]

Network topology is the arrangement of the elements of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial fieldbusses and computer networks.

Advantages:

It is easy to handle and implement.

It is best suited for small networks.

Disadvantages:

The cable length is limited. This limits the number of stations that can be connected.

This network topology can perform well only for a limited number of nodes.

Draw a flow chart that accepts mass and volume as input from the user. The flow chart should compute and display the density of

TiliK225 [7]

Answer:

See attachment for flowchart

Explanation:

The flowchart is represented by the following algorithm:

1. Start

2. Input Mass

3. Input Volume

4 Density = Mass/Volume

5. Print Density

6. Stop

The flowchart is explained by the algorithm above.

It starts by accepting input for Mass

Then it accepts input for Volume

Step 4 of the flowchart/algorithm calculated the Density using the following formula: Density = Mass/Volume

Step 5 prints the calculated Density

The flowchart stops execution afterwards

Note that the flowchart assumes that the user input is of number type (integer, float, double, etc.)

Which is true about POP3 and IMAP for incoming email?

IceJOKER [234]

<h2>Answer:</h2>

Option A: Both POP3 and IMAP keep email on an email server by default.

is the correct answer.

<h2>Explanation:</h2>

Following points will make the idea of POP3 and IMAP clear:

POP3 is the acronym for Post Office Protocol 3.
POP3 is the method of receiving emails in which the emails received on the app can be downloaded on to the computer by having an internet connection.
These downloaded emails can be viewed offline whenever needed and managed as well.
POP3 makes it possible that the storage space of the default server do not run short as the downloaded emails are deleted from the server.

IMAP stands for Internet Message Access Protocol.
It is the method in which the mails are viewed and managed directly on the internet server instead of downloading them on the computer.
IMAP makes sure to manage the mails so carefully and timely so that unimportant mails are deleted to make sure that the storage space does not run short.

<h3>Conclusion:</h3>

So from these points we can make sure that both ways keep emails on email server but POP3 have option to download mails from server while IMAP dont have.
