How many permutations for a 7 characters in length string, which contains all following letters R, X, S, Y, T, Z, U, has either the string 'RXS' or string 'ZU' in the 7 characters string?

Answers

Answer 1

Answer:

Following are the solution to this question:

Explanation:

In the following forms, RXS can appear:  

[tex]R X S \_ \_ \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

[tex]\_ R X S \_ \_ \_[/tex] it may look like that really,  [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

[tex]\_ \_ R X S \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

[tex]\_ \_ \_ R X S \_[/tex] it may look like that really,  [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

[tex]\_ \_ \_ \_ R X S[/tex] it may look like that really,  [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.  

And we'll have a total of [tex]24 \times 5 = 120[/tex] permutations with both the string RXS.

In the following forms, UZ can appear:

[tex]U Z \_ \_ \_ \_\ _[/tex]  They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ UZ \_ \_ \_ \_[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ \_ U Z \_ \_ \_[/tex]They can organize your remaining 5 characters through 5 categories! Procedures  [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ \_ \_ U Z \_ \_[/tex]They can organize your remaining 5 characters through 5 categories! Procedures  [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ \_ \_ \_ U Z \_[/tex] They can organize your remaining 5 characters through 5 categories! Procedures  [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

[tex]\_ \_ \_ \_ \_ U Z[/tex] They can organize your remaining 5 characters through 5 categories! Procedures  [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]

There may be [tex]120 \times 6 = 720[/tex] ways of complete permutations.

An algorithm whose worst-case time complexity is bounded above by a polynomial function of its size is called a(n)

Answers

Answer:

polynomial-bounded algorithms

Explanation:

There are two algorithm complexities and they are time and space complexities. They can be denoted with the big-O notation. The big-o notation for a time and space complexity gets the worst-case time and space respectively.

The time complexity gets the measure of the execution time of an algorithm. When the time function is a polynomial ( k^n + k^n-1 ...) then the algorithm is said to be a polynomial-bounded algorithm.

Documenting findings, actions, and outcomes of network troubleshooting calls is an essential part of the troubleshooting process. List the reasons why documentation is critical, and discuss the form that this documentation could take (e.g. blogs, wikis, professional document management software, etc). Include a detailed description of what information would need to be saved.

Answers

Answer:

The main purpose of documentation is for future reference on the cost, materials, procedures, and techniques used in a task. It can be in form of a video log, report, digital text document or software, etc.  

Explanation:

Documentation is an important practice of taking notes of events during a process. It could in the process of creating or discovering new ideas or repair or management of existing processes. It holds the time, cost, technique, event name, measures-taken, etc, that would totally describe the event.

To prevent long page load times for pages containing images, it is best to use a compressed file format such as JPG, as well as appropriate image dimensions and
resolution.
magnification.
orientation.
colors.

Answers

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The given options to this question are:

resolution. magnification. orientation. colors.

The correct option to this question is 1. i.e.

Resolution.

The resolution of an image determines how many pixels per inch an image contains. Image having a higher resolution takes long page load times for a page and lower resolution takes less page load time. So, to prevent long page load times for pages containing images, it is best to use compressed file formation as well as appropriate image dimension and resolution.

While other options are not correct because:

Magnification, orientation, and color does not affect the page load time. Page load time for images only affected by the dimension and resolution of the images.

What is the main advantage of using a WYSIWYG (“what you see is what you get”) editor when constructing a website?
Only one programming language is required.
Websites may have more professional construction.
Knowledge of HTML is not required.
Website templates are not necessary.

Answers

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct answer among the given options to this question is:

Knowledge of HTML is not required.

Because when you are constructing a website using WYSIWYG (“what you see is what you get”) editor, then you don't need the knowledge of HTML. Because, when you use WYSIWYG editor to insert button, table, images, text, paragraph, etc. It will automatically insert HTML code behind the page. For example, you can insert a form and a submit button using drag and drop with the help of WYSIWYG (“what you see is what you get”)  editor, for this purpose, you don't need exact knowledge of HTML. WYSIWYG (“what you see is what you get”)  automatically inserts the HTML for the form and button on a website page.

While other options are not correct because:

Using the WYSIWYG (“what you see is what you get”)  editor, you can use different programming languages in your website, such as VB.net, Asp.Net, C#, Javascript, Bootstrap, etc. It is not necessarily that you may have more professional construction and in WYSIWYG (“what you see is what you get”)   website templates are mostly used and modified using WYSIWYG editor.
