The minimum height reached by the barnacle is ___ m.

Answers 3

Answer:

The maximum would be 1 and the minimum would be -1.

And the length of the barnacle travel would be 2pi.

From the diagram, the minimum height that is reached by the barnacle would be 1m.

Why is this the minimum height?

The Barnacle is going around the water level in the shape of a circle in which the water level is the diameter.

the minimum height the barnacle can be reached is constricted by the radius such that it is the same as the radius of the circle. which means that the minimum height is 1m.

0.15 m The minimum height reached by barnacles is typically around 0.15 meters, as they usually attach themselves to the surface of rocks or other substrates in shallow water. Barnacles are well-known for their ability to live and thrive in very shallow water, as their thick shells offer them protection from predators and their hard shells allow them to cling firmly to surfaces.

Nam owns a used car lot. He checked the odometers of the cars and recorded how far they had driven. He then created both a histogram and a box plot to display this same data (both diagrams are shown below). Which display can be used to find how many vehicles had driven more than 200{,}000\,\text{km}200,000km200, comma, 000, start text, k, m, end text (kilometers)? Choose 1 answer: Choose 1 answer: (Choice A) A The histogram (Choice B) B The box plot Which display can be used to find that the median distance was approximately 140{,}000\,\text{km}140,000km140, comma, 000, start text, k, m, end text? Choose 1 answer: Choose 1 answer: (Choice A) A The histogram (Choice B) B The box plot

Answer:

(a) The correct option is (A).

(b) The correct option is (B).

Step-by-step explanation:

Nam collected the data for the distance traveled by all the cars in his car lot.

(a)

A histogram is a bar graph representing the distribution of a random variable. The height of the bars of the histogram represents the frequency for a specific interval.

If Nam wants to know how many vehicles had driven more than 200,000 km, the histogram would be the best display of this data. This is because the histogram shows the frequency for various interval values.

The correct option is (A).

(b)

A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,

  • Minimum (shown at the bottom of the chart)
  • First Quartile (shown by the bottom line of the box)
  • Median (or the second quartile) (shown as a line in the center of the box)
  • Third Quartile (shown by the top line of the box)
  • Maximum (shown at the top of the chart).

So, if Nam wants to find whether the median distance was approximately 140,000 km, a box plot would be a better choice. This is because the box plot represents the median of the data by a line within the box.

The correct option is (B).

a and b

Step-by-step explanation:

In this project, you’ll create a security infrastructure design document for a fictional organization. The security services and tools you describe in the document must be able to meet the needs of the organization. As the security consultant, the company needs you to add security measures to the following systems: a. An external website permitting users to browse and purchase widgets b. An internal intranet website for employees to use c. Secure remote access for engineering employees d. Reasonable, basic firewall rules e. Wireless coverage in the office f. Reasonably secure configurations for laptops Since this is a retail company that will be handling customer payment data, the organization would like to be extra cautious about privacy. They don't want customer information falling into the hands of an attacker due to malware infections or lost devices. Engineers will require access to internal websites, along with remote, command line access to their workstations.

Answer:

Explanation:

It is very important for the organisation to implement maximum security to the infrastructure. The main data totally belongs to the customers which mainly has customers' personal information and bank details. So, here are few things that needs to be look at as a security expert:

Encryption: the implementation of encryption tool to encrypt the data especially passwords and card details of the customer will be help in securing the infrastructure. Encryption makes it hard for anyone to be able decrypt the actual data.

Firewall: This is the beginning stage of implementing security to an infrastructure. Firewall will help greatly in blocking traffic that are unwanted from entering into the infrastructure. This also blocks untrusted traffic to the application server too.

SSL certificate: Implementation of SSL certificate to the website or the application will help greatly in securing and protecting the application for you against online hackers.

Every device belongs to your system must be implemented with anti-malware softwares that can able to detect malware present in the system.

Taylor surveys students in one grade level who own at least one pet. She finds that 50% of the students surveyed own 2 pets, 3 students own 3 pets each, and 2 students own 4 pets each. Eight of the students in the grade own 1 pet. Considering the number of pets as the random variable, X, which of the following is the probability distribution, PX(x)? A probability distribution is shown. The probability of 1 is 0.3; 2 is 0.5; 3 is 0.11; 4 is 0.08. A probability distribution is shown. The probability of 1 is 0.28; 2 is 0.5; 3 is 0.1; 4 is 0.13. A probability distribution is shown. The probability of 1 is 0.61; 2 is 0.5; 3 is 0.22; 4 is 0.15. A probability distribution is shown. The probability of 1 is 0.53; 2 is 0.5; 3 is 0.2; 4 is 0.27.

Answer:

Step-by-step explanation:

We know that half of the students has two pets. The rest of the students make up the other half. So, we have 3 students + 2 students + 8 students = 13 students that make half of the sample population

That means total number of students being surveyed is 13+13=26 students

Then we work out the probability

P(One pet) = 8/26 = 4/13

P(Two pets) = 1/2

P(Three pets) = 3/26

P( Four pets) = 2/26 = 1/13

The probability distribution is shown in the table below. Let  be the number of pets and  is the probability of owning the number of pets

First, we need to work out the total number of students who were being surveyed.

We know that half of the students has two pets. The rest of the students make up the other half. So, we have 3 students + 2 students + 8 students = 13 students that make half of the sample population

That means total number of students being surveyed is 13+13=26 students

Then we work out the probability

P(One pet) = 8/26 = 4/13

P(Two pets) = 1/2

P(Three pets) = 3/26

P( Four pets) = 2/26 = 1/13

The probability distribution is shown in the table below. Let  be the number of pets and  is the probability of owning the number of pets
