Answer:

d. CSS can be included in an HTML document

Explanation:

HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are not programming languages. They are, in fact, a different kind of computer languages and are some of the essential tools used in common web pages nowadays.

HTML and HTML5 are different. The latter is a new version of HTML which implies some improvements such as the availability of other technologies and features not found in HTML.

HTML is a markup language, i. e., a kind of computer language like TeX, LaTeX, troff, among others, that defines the structure of a text, and it tells to a computer how to show it in a web page using tags embedded into the content of the document. For example, a paragraph is defined using a tag like this  text inside , a title: <title> text inside </title>, and so on with images, tables, et cetera.

CSS is a style sheet language, that is, another kind of computer language whose main emphasis is the appearance of the web page, telling the computer the presentation the structured document is about to have, that is, how the document should look.

As a result, CSS is used to describe the presentation of documents written in HTML and can be included in it.

On the other side, programming languages are formal languages (like the ones of mathematics and logic), that is, with some rules and a particular syntax intended to "communicate instructions to a machine, particularly a computer" [Wikipedia, 2019], and some examples of high-level programming languages are those like C, Python, Fortran, Lisp, CommonLisp, Pascal, JavaScript, among many others.

Given four inputs: a, b, c & d, where (a, b) represents a 2-bit unsigned binary number X; and (c, d) represents a 2-bit unsi

Amiraneli [1.4K]

Answer:

z = a.c' + a.b.d' + b.c'.d'

Explanation:

The truth table for this question is provided in the attachment to this question.

N.B - a' = not a!

The rows with output of 1 come from the following relations: 01 > 00, 10 > 00, 10 > 01, 11 > 00, 11 > 01, 11 > 10

This means that the Boolean expression is a sum of all the rows with output of 1.

z = a'bc'd' + ab'c'd' + ab'c'd + abc'd' + abc'd + abcd'

On simplification,

z = bc'd' + ab'c' + ac'd' + ac'd + abc' + abd'

z = ac' + abd' + bc'd'

Hope this helps!

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0,

TEA [102]

Answer:

ranforce = randi([0, 12]);

if (ranforce == 0)

disp('There is no wind')

else if(ranforce>0 && ranforce <7)

disp('There is a breeze')

else if(ranforce>6 && ranforce <10)

disp('This is a gale')

else if(ranforce>9 && ranforce <12)

disp('It is a storm')

else if(ranforce==12)

disp('Hello, Hurricane!')

end

Explanation:

Replace all switch case statements with if and else if statements.

An instance is:

case {7,8,9}

is replaced with

else if(ranforce>9 && ranforce <12)

All other disp statements remain unchanged

)Which of following can be thrown using the throwstatement?

Amanda [17]

Answer:

All of Given

Explanation:

The throw keywords can be used to throw any Throwable object. The syntax is :

throw <Throwable instance>

Note that Error and Exception are subclasses of Throwable while RuntimeException is a subclass of Exception. So the hierarchy is as follows:

Throwable

-- Error

-- Exception

-- RuntimeException

And all of these are valid throwable entities. As a result "All of Given" is the most appropriate option for this question.
