Answer:

Explanation:

TCP Transmission Control Protocol, is an internet protocol to exchange data, is one of the most main protocols of the internet is used from the beginning, with UPD is used to transfer data too, but is less secure than TCP, but is faster than TCP, in this case, UDP is used to transfer music or videos, and TCP is used to transfer websites and database.

Answer:

# F F F F 0 0

# F F 0 0 F F

# 0 0 F F F F

Explanation:

Hex values are your friend.

The first two digits represent red.

# F F 0 0 0 0 - Red

The second two digits represent green.

# 0 0 F F 0 0 - Green

The third two digits represent blue.

# 0 0 0 0 F F - Blue

If you know yellow is a combination of red and green, you express the corresponding digits.

# F F 0 0 0 0 - Red

# 0 0 F F 0 0 - Green

-------------------------------

# F F F F 0 0 - Yellow

Similarly,

If you know magenta is a combination of red and blue, you express the corresponding hex digits.

# F F 0 0 0 0 - Red

# 0 0 0 0 F F - Blue

-----------------------------

# F F 0 0 F F - Magenta

And finally,

If you know cyan is a combination of green and blue, you express the corresponding hex digits.

# 0 0 F F 0 0 - Green

# 0 0 0 0 F F - Blue

----------------------------

# 0 0 F F F F - Cyan

What does it mean to "express the digits"?

If you know anything about how color works on a computer, you'll know that you can express a certain amount of red, green and blue to get almost any color. These are known as "RGB" values. In RGB, the red, green or blue can individually go from 0 - 255. Think of it like a slider for how much you want of each color.

In RGB:

RGB (255, 255, 255) - White

Hex is just a really convenient and shorthand way to write the RGB color values.

In Hex:

#FFFFFF - White

Preparing for jobs that are high in demand allows an individual to focus their development of human capital on those careers.

Focus your development of human capital on those careers

<u>Explanation:</u>

As the demand for the job is high, there is no denying the fact that it will increase the likelihood of getting a job. It is a simple proportion, more the number of jobs, more are the chances of getting them.

Last but not least it will also allow an individual to be more attractive to employers in those fields. As an individual prepares for the job, they will acquire certain skills and knowledge that are capable of letting them being perceived as attractive.

For this programming assignment you will implement the Naive Bayes algorithm from scratch and the functions to evaluate it with

DanielleElmas [232]

Bayes’ Theorem provides a way that we can calculate the probability of a piece of data belonging to a given class, given our prior knowledge.

P(class|data) = (P(data|class) * P(class)) / P(data)

Where P(class|data) is the probability of class given the provided data.

Explanation:

Naive Bayes is a classification algorithm for binary and multiclass classification problems.
It is called Naive Bayes or idiot Bayes because the calculations of the probabilities for each class are simplified to make their calculations tractable.

This Naive Bayes tutorial is broken down into 5 parts:

Step 1: Separate By Class : Calculate the probability of data by the class they belong to, the so-called base rate. Separate our training data by class.

Step 2: Summarize Dataset : The two statistics we require from a given dataset are the mean and the standard deviation

The mean is the average value and can be calculated using :

mean = sum(x)/n * count(x)

Step 3: Summarize Data By Class : Statistics from our training dataset organized by class.

Step 4: Gaussian Probability Density Function : Probability or likelihood of observing a given real-value. One way we can do this is to assume that the values are drawn from a distribution, such as a bell curve or Gaussian distribution.

Step 5: Class Probabilities : The statistics calculated from our training data to calculate probabilities for new data. Probabilities are calculated separately for each class. This means that we first calculate the probability that a new piece of data belongs to the first class, then calculate the second class, on for all the classes.

Answer:

Explanation:

First when you are troubleshooting a client your main goal is to solve their issue, you dont want to say hey call later i cant help you or say call someone else because picture this you need help and someone hangs up on you or says (B.) or (C.) it comes off as rude i would say. Regarding (A.) im not 100% sure what exactly do you mean by user's site? But asking for their manager (D.) or someone else (preferably higher up) seems to be the right action to be taken.
