Following is attached the solution of each part step-by-step. I hope it will help you!
Explanation:
Answer:
The probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.964
If the survey subjects <em>volunteered</em> to respond , then those with the strongest opinions are most likely respond. The survey sample is then not randomly selected, the survey may have a <em>response bias.</em>
Explanation:
Let P(at least one is more careful about personal information when using a public Wi-Fi hotspot) denote the probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot, then we have the equation
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot)
- If 67% of Internet users are more careful about personal information when using a public Wi-Fi, then 33% of them are not.
P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot) = ≈ 0.036
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - 0.036 = 0.964
Question
Student presentation concepts from another source
Letitia - a step-by-step process of breaking down glucose into energy
Mana - repeating process of the steps of the cell division, going from interphase to division, and back to interphase.
Paul - a series of organisms that show similar characteristics and compare them to those that do not
Which best describes the SmartArt graphic layout each student should use?
Answer:
Letitia would use a process, Maria would use a cycle, and Paul would use a relationship.
Explanation:
Letita's assignment requires her to show how glucose can be broken down into energy, this requires a series of steps in s linear fashion, meaning it would be best suited to a process-style diagram.
Marta's project involves showing the steps of the cell cycle: the clue is in the name. This process is not linear, and instead repeats itself, meaning it fits to a cycle diagram (i.e. a circular diagram)
Paul is comparing and contrasting different organisms. Therefore, he should use a relationship diagram to show shared characteristics as well as features that differ.
Answer:
In the context of cyber security, social engineering (SE) is a deceptive practice that exploits human <u>weaknesses </u> by inducing victims to interact with a digital device in a way that is not in their best interest. Many of these attacks begin with<u> spam</u> , which is defined as unsolicited messages that are usually sent in massive numbers using electronic mail systems. A spam <u>filter</u> uses a set of rules to examine email messages and determine which are spam. There are four common types of spam filters.<u> Content </u>filters examine the content within a message for certain words or phrases commonly used in spam emails.<u> Header</u> filters review the email header for falsified information, such as spoofed IP addresses. <u>Blacklist</u> filters block mail that originates from IP addresses of known spammers. <u>Permission </u> filters block or allow mail based on the sender's address. <u>Phishing</u> is an email scam that masquerades as a message from a(n) legitimate company or agency of authority, such as the IRS. <u>Pharming</u> redirects Web site traffic to fraudulent Web sites that distribute malware, collect personal data, sell counterfeit products, and perpetrate other scams. A rogue <u>antivirus </u> exploit usually begins with a virus warning and an offer to disinfect the infected device. Some software is not exactly malware, but it is a nuisance. A <u>PUA </u>takes up residence on a digital device and seems impossible to disable or remove.
