Suppose you are developing a data visualization application DataViz which calls some functions from a statistics library class SuperStats. You recently heard about another statistics library UberStats with supposedly significantly better performance than SuperStats. Explain how you would redesign the DataViz class using the Adapter pattern so that DataViz can be configured at runtime to use either SuperStats or UberStats. Does your design use dependency inversion and/or dependency injection? Explain

Answers

Answer 1

Answer:

By using dependency injection, create the adapter to adapt both the DataViz and the UberStats interface as expected.

Explanation:

Adapters are used in Objected-oriented programming to run or convert the output of one class object to another. The DataViz class currently uses the SuperStats class as an adaptee to get and output statistical results.

Write a new code from the scratch is tedious, so, the UberStats class dependencies are injected in the adapter and the DataViz and UberStats class functionalities can be experimented with.

Answers

Answer:

Software piracy.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.

Simply stated, it's a computer program or application that comprises of sets of code for performing specific tasks on the system.

Basically, softwares are categorized into two (2) main categories and these are;

I. Open-source software.

II. Proprietary software.

A proprietary software is also known as a closed-source software and it can be defined as any software application or program that has its source code copyrighted and as such cannot be used, modified or distributed without authorization from the software developer. Thus, it is typically published as a commercial software that may be sold, licensed or leased by the software developer (vendor) to the end users with terms and conditions.

Some examples of proprietary software are Microsoft Windows, macOS, Adobe photoshop etc.

Furthermore, a proprietary software license avail end users the opportunity to install and use the software after agreeing to the terms of its license.

Software piracy can be defined as an act which typically involves the unauthorized use, duplications, or distribution of a software that is legally copyrighted or protected, without an express permission from the software manufacturer (owner).

Generally, software manufacturers (owners) deal with problems associated with software piracy by placing a limit on the number of times or durations that an end user is allowed to use a particular software before registering (subscribing) as the authorized owner of that software.

Not sure what language this is, but it looks like input( ) is a function that displays whatever you pass in, and then gets the responding user input.

Therefore, when you assign the function to a variable named "name", whatever the user input is will be assigned to it.

var name;

What is the output of the sum of 1001011 and 100011 displayed in hexadecimal?

Answers

Answer:

[tex]1001011_2[/tex]    [tex]+[/tex]   [tex]100011_2[/tex]   [tex]=[/tex]    [tex]6E_{hex}[/tex]

Explanation:

Required

[tex]1001011_2 + 100011_2 = []_{16}[/tex]

First, carry out the addition in binary

[tex]1001011_2[/tex]    [tex]+[/tex]   [tex]100011_2[/tex]   [tex]=[/tex]    [tex]1101110_2[/tex]

The step is as follows (start adding from right to left):

[tex]1 + 1 = 10[/tex] --- Write 0 carry 1

[tex]1 + 1 + 1(carry) = 11[/tex] ---- Write 1 carry 1

[tex]0 + 0 + 1(carry) = 1[/tex] ---- Write 1

[tex]1 + 0 = 1[/tex] --- Write 1

[tex]0 + 0 = 0[/tex] ---- Write 0

[tex]0 + 0 = 0[/tex] ---- Write 0

[tex]1 + 1 = 10[/tex] --- Write 0 carry 1

No other number to add ; So, write 1 (the last carry)

So, we have:

[tex]1001011_2[/tex]    [tex]+[/tex]   [tex]100011_2[/tex]   [tex]=[/tex]    [tex]1101110_2[/tex]

Next, convert [tex]1101110_2[/tex] to base 10 using product rule

[tex]1101110_2 = 1 * 2^6 +1 * 2^5 + 0 * 2^4 + 1 * 2^3 + 1 * 2^2 + 1 * 2^1 + 0 * 2^0[/tex]

[tex]1101110_2 = 64 +32 + 0 + 8 + 4 + 2 + 0[/tex]

[tex]1101110_2 = 110_{10}[/tex]

Lastly, convert [tex]110_{10}[/tex] to hexadecimal using division and remainder rule

[tex]110/16 \to 6\ R\ 14[/tex]

[tex]6/16 \to 0\ R\ 6[/tex]

Write the remainder from bottom to top;

[tex]110_{10} = 6(14)_{hex}[/tex]

In hexadecimal

[tex]14 \to E[/tex]

So, we have:

[tex]110_{10} = 6E_{hex}[/tex]

Hence:

[tex]1001011_2[/tex]    [tex]+[/tex]   [tex]100011_2[/tex]   [tex]=[/tex]    [tex]6E_{hex}[/tex]

what is the correct way to write h1 tag

Answers

Answer:

[tex]\huge\boxed{\texttt{<h1> </h1>}}[/tex]

Explanation:

The h1 tag in HTML is used to create title-like text.

HTML stands for Hyper Text Markup Language, and is the most common programming language used for website creation with content that can be read.

Additionally, CSS (Cascading Style Sheets) is used for the design of a document, such as colors or designs that are on the website. JavaScript is used for scripting websites such as interactive features that can be used via JavaScript.

h1 is the most common use for a big title on a screen. For example, if you're writing an article, you might put the name of your article title in h1 to give it that title emphasis.

Any tags in HTML will open with <> and end with </>, replacing whatever is inside of those tags with the type of style you want. So, an h1 tag would work like this.

<h1> Hello there! </h1>

The <h1> starts the next string into the h1 format, and the </h1> tells it to stop parsing what's after into the h1 tag.

Hope this helped!

Walden is looking at his company’s regional sales numbers. He needs a quick estimate of the total sales across regions. The numbers are confusing to read because of the trailing decimals. What function can Walden use to round the numbers to the nearest whole number?

A.
=ROUND(number)
B.
=ROUND(0)
C.
=ROUND(number, 0)
D.
=ROUND(1)
E.
=ROUND(number, 1)

Answers

Answer:

C. =ROUND(number, 0)

Explanation:

The ROUND function in MS Excel is used in rounding off numbers input in the function to a specified number of decimal places

The cell address containing the original number to be rounded off, or the original number is entered as the first argument of the function, while the second argument is the number of digits the original number is to be rounded to

In order to round to the nearest whole number, the second argument would be 0 which result in the removal of the numbers after the decimal place and rounding the last integer on the bases of the value of the number after the decimal point

Therefore, to round the original number to the nearest whole number, the function Walden should use is =ROUND(number, 0).
