a_sh-v [17]

Answer:

The best answer is letter D.

Explanation:

Downloading of files without your permission is a form of security threat and attack. You as unwilling victim will have your files and private information stolen.

One of the basics of internet security is to terminate any connection that you have in a network to stop the possible attack or threat. Worst case scenario is we can shut down our computers or devices or gadgets. But if we can just terminate the connection without performing a force shut down on the device, it is much better. This will give us more time to save what we are working on and to prevent losing important works or data. Terminating the connection from the network comes in various activities such as:

*Disconnect from the internet - this is one of the most effective method. As most of the attacks are coming from external threats such a hacking.

*Closing the browser - this could be helpful as well. Hackers are using browser to monitor their victims. And malwares and adwares are most active while we use browsers as they are embedded and using it to propagate to peform their activities.

*Disconnect from the local network - if you have closed the internet connection and any active software that you are working on presently and the downloading of files still persists, probably the attack comes from your local network. You must close any connection that you have within the local network.

*Deleting the recent files you have downloaded - You must delete any recent files that you just downloaded from your email or from the internet. There might be malware embedded in the file. Malwares are used by hackers to get in to their victims computer without them knowing it.

Then after terminating all the connections, you must call on your Instructor's attention. He / She is the authority in charge and must be aware of the situation.

How do most business applications and websites process credit card transactions?

klasskru [66]

Answer:

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

Explanation:

Most business applications and websites use and process the credit card for their transaction.

For example, e-commerce website such as ali baba, am a zon, accepting credit card transaction when the customer gets to purchase any product from their stores. Their transactions are processed by in house credit card apps/service. But these apps/services owned by a third party. They just give you API services and related code to integrate the credit card services.

By using their in-house credit card apps/services, they know that user has transferred the money into their account for the purchased product, upon receiving payment confirmation, they then prepare and dispatch the order.

So, the correct answer to this question is:

To process the credit card transactions, they license third-party credit card apps/services backed by the internet merchant who is responsible for handling and managing the money of the business account.

A computer retail store has 15 personal computers in stock. A buyer wants to purchase 3 of them. Unknown to either the retail st

Dima020 [189]

Answer:

a. 1365 ways

b. Probability = 0.4096

c. Probability = 0.5904

Explanation:

Given

PCs = 15

Purchase = 3

Solving (a): Ways to select 4 computers out of 15, we make use of Combination formula as follows;

$^nC_r = \frac{n!}{(n-r)!r!}$

Where $n = 15\ and\ r = 4$

$^{15}C_4 = \frac{15!}{(15-4)!4!}$

$^{15}C_4 = \frac{15!}{11!4!}$

$^{15}C_4 = \frac{15 * 14 * 13 * 12 * 11!}{11! * 4 * 3 * 2 * 1}$

$^{15}C_4 = \frac{15 * 14 * 13 * 12}{4 * 3 * 2 * 1}$

$^{15}C_4 = \frac{32760}{24}$

$^{15}C_4 = 1365$

Hence, there are 1365 ways 

Solving (b): The probability that exactly 1 will be defective (from the selected 4)

First, we calculate the probability of a PC being defective (p) and probability of a PC not being defective (q)

From the given parameters; 3 out of 15 is detective;

So;

$p = 3/15$

$p = 0.2$

$q = 1 - p$

$q = 1 - 0.2$

$q = 0.8$

Solving further using binomial;

$(p + q)^n = p^n + ^nC_1p^{n-1}q + ^nC_2p^{n-2}q^2 + .....+q^n$

Where n = 4

For the probability that exactly 1 out of 4 will be defective, we make use of

$Probability = ^nC_3pq^3$

Substitute 4 for n, 0.2 for p and 0.8 for q

$Probability = ^4C_3 * 0.2 * 0.8^3$

$Probability = \frac{4!}{3!1!} * 0.2 * 0.8^3$

$Probability = 4 * 0.2 * 0.8^3$

$Probability = 0.4096$

Solving (c): Probability that at least one is defective;

In probability, opposite probability sums to 1;

Hence;

Probability that at least one is defective + Probability that at none is defective = 1

Probability that none is defective is calculated as thus;

$Probability = q^n$

Substitute 4 for n and 0.8 for q

$Probability = 0.8^4$

$Probability = 0.4096$

Substitute 0.4096 for Probability that at none is defective

Probability that at least one is defective + 0.4096= 1

Collect Like Terms

Probability = 1 - 0.4096

Probability = 0.5904

Write an algorithm to find perimeter of circle

Anna11 [10]

Answer:

Here’s one!

Given [math]R[/math], the radius of the circle.

Let [math]N,D\leftarrow 0[/math]

Repeat until [math]D[/math] is large enough (about 1,000,000)

[math]x,y\leftarrow U[0,1][/math]

If [math]x^2 + y^2\le 1[/math] then [math]N\leftarrow N+1[/math]

[math]D\leftarrow D+1[/math]

[math]P\leftarrow\frac{8NR}{D}[/math]

Return [math]P[/math]

[math]U[0,1][/math] is a uniform random number in the range [math][0,1][/math].
