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.

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.

Answer:

Bluetooth uses this medium to connect two devices.

b. fiber optics
c. infrared light
d. radio signals

Answers

Answer:

D

Explanation:

Bluetooth is the wireless technology which allows for the exchange of the data between different devices. It uses wavelength to transmit information and generally works with short rage devices.

Due to Bluetooth relies on the range of devices and hence it depends on the UHF radio waves. These have a range of 2.4 to 2.5 Ghz. Such that the devices can talk to each other. The usage is control automation system.

Hence the option D is correct.

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.

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.
