Answer:
Explanation:
Usually, applications would have the capability of using either one of these options. But for the sake of the question here are some that usually prefer one method over the other.
Any program that targets an API usually uses Sequential access. This is because API's contain all of the data as objects. Therefore, you need to access that object and sequentially navigate that object to the desired information in order to access the data required.
A music application would have access to an entire folder of music. If the user chooses to set the application to randomly play music from that folder, then the application will use a Random Access method to randomly choose the music file to load every time that a song finishes.
Shawn's supervisor has tasked him with determining how the company can increase the security of its Wi-Fi. Shawn plans to present several options to his supervisor and ask her to check his work. Which of the following is not a strong security method? (Select TWO.)
a. Disabling SSID
b. WPS
c. MAC filtering
d. Setting encryption
Answer:
The not strong security methods are:
a. Disabling SSID
b. WPS
Explanation:
When you disable SSID, you only make your Wi-Fi secure for the less determined attackers. By disabling the SSID (network name), those who are less technically inclined are prevented from connecting to the network but, this will not deter a more determined and technically savvy adversary. The best two options are MAC filtering and setting encryption. WPS (Wi-Fi Protected Setup) enables the process of connecting to a secure wireless network from a computer or other device easier instead of making it harder.
with the aid of examples explain the differences between open source software and licensed software
Answer:
Explanation:
Source is when a company go no limits to run the software but can easily be taken done by a complaint or two or a bug while a licensed it a protected version of the software.
Write a program palindrome.py that prompts for a sequence of words or numbers on a single line and checks if the entries are palindromes or not. A word or a number is a palindrome if it remains unchanged when reversed. e.g. rotor is a palindrome; but python is not a palindrome. e.g. 737 is a palindrome; but 110 is not a palindrome. The program receives the sequence as input and returns True if an entry is a palindrome or False if an entry is not a palindrome. Print the boolean value on one line. Print the palindromes count on the next line.
Answer:
Explanation:
The program first asks the user for the sequence of words. Then it splits the sequence into an array of words. Then it loops through the array checking each word to see if it is a palindrome. If it is it prints the word, the boolean value, and adds 1 to the palindrome_count variable. Otherwise it prints the word, false, and moves on to the next word in the list. Finally, it prints out the total value of palindrome_count.
word = input("Enter sequence of words: ")
word_list = word.split(' ')
print(word_list)
palindrome_count = 0
for word in word_list:
print('\n\n')
reverse = word[::-1]
if word == reverse:
print(word, end='\n')
print(True, end="\n")
palindrome_count += 1
else:
print(word, end='\n')
print(False, end='\n')
print("\n\nNumber of Palindromes in Sequence: " + str(palindrome_count))

What hardware architectures are not supported by Red Hat?
, , and angle x and angle y are both in the first quadrant.
Answer:
[tex]\tan(x+y) = 3.73[/tex]
Explanation:
The missing part of the question are:
[tex]\sin(x) = \frac{1}{2}[/tex]
[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex]
Required
[tex]\tan(x + y)[/tex]
First, we calculate [tex]\sin(y)[/tex] and [tex]\cos(x)[/tex]
We have:
[tex]\sin^2(x) + \cos^2(x) = 1[/tex]
So:
[tex](1/2)^2 + \cos^2(x) = 1[/tex]
Collect like terms
[tex]\cos^2(x) = 1 - (1/2)^2[/tex]
[tex]\cos^2(x) = 1 - \frac{1}{4}[/tex]
Take LCM
[tex]\cos^2(x) = \frac{4-1}{4}[/tex]
[tex]\cos^2(x) = \frac{3}{4}[/tex]
Square roots of both sides
[tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]
Similarly,
[tex]\sin^2(y) + \cos^2(y) = 1[/tex]
So:
[tex]\sin^2(y)+(\sqrt 2/2)^2 = 1[/tex]
[tex]\sin^2(y)+ (2/4) = 1[/tex]
[tex]\sin^2(y)+1/2 = 1[/tex]
Collect like terms
[tex]\sin^2(y) = 1 - 1/2[/tex]
Take LCM
[tex]\sin^2(y) = \frac{2 -1}{2}[/tex]
[tex]\sin^2(y) = \frac{1}{2}[/tex]
Square roots of both sides
[tex]\sin(y) = \frac{1}{\sqrt2}[/tex]
Rationalize
[tex]\sin(y) = \frac{\sqrt2}{2}[/tex]
So, we have:
[tex]\sin(x) = \frac{1}{2}[/tex] [tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]
[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex] [tex]\sin(y) = \frac{\sqrt2}{2}[/tex]
[tex]\tan(x) = \sin(x) \div \cos(x)[/tex]
[tex]\tan(x) = \frac{1}{2} \div \frac{\sqrt 3}{2}[/tex]
Rewrite as:
[tex]\tan(x) = \frac{1}{2} * \frac{2}{\sqrt 3}[/tex]
[tex]\tan(x) = \frac{1}{\sqrt 3}[/tex]
Rationalize
[tex]\tan(x) = \frac{\sqrt 3}{3}[/tex]
Similarly
[tex]\tan(y) = \sin(y) \div \cos(y)[/tex]
[tex]\tan(y) = \frac{\sqrt 2}{2} \div \frac{\sqrt 2}{2}[/tex]
[tex]\tan(y) = 1[/tex]
Lastly,
[tex]\tan(x + y)= \frac{\tan(x) + \tan(y)}{1 - \tan(x) \cdot \tan(y)}[/tex]
[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3} \cdot 1}[/tex]
[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3}}[/tex]
Combine fractions
[tex]\tan(x + y)= \frac{\frac{\sqrt3+3}{3}}{\frac{3 - \sqrt3}{3}}[/tex]
Cancel out 3
[tex]\tan(x + y)= \frac{\sqrt3+3}{3 - \sqrt3}[/tex]
Using a calculator
[tex]\tan(x+y) = 3.73[/tex]
A company is deploying NAFDs in its office to improve employee productivity when dealing with paperwork. Which of the following concerns is MOST likely to be raised as a possible security issue in relation to these devices?
A. Sensitive scanned materials being saved on the local hard drive
B. Faulty printer drivers causing PC performance degradation
C. Improperly configured NIC settings interfering with network security
D. Excessive disk space consumption due to storing large documents
Answer:
D. Excessive disk space consumption due to storing large documents.
Explanation:
When a company is planning to use NAFDs in its office rather than paper work, the efficiency of employees will increase as unnecessary paper work takes time in handling and printing. When data is stored on disks there is a risk that employees store large or irrelevant files in the disk which will create storage issues.
Write a program that repeatedly accepts as input a string of ACGT triples and produces a list of the triples and the corresponding amino acids, one set per line. The program will continue to accept input until the user just presses ENTER without entering any DNA codes.
Answer:
Explanation:
The following code is written in Python. I created a dictionary with all the possible gene combinations and their corresponding amino acids. The user then enters a string. The string is split into triples and checked against the dictionary. If a value exists the gene and amino acid is printed, otherwise an "Invalid Sequence" error is printed for that triple. The program has been tested and the output can be seen in the attached image below.
def printAminoAcids():

#Write a function called find_median. find_median #should take as input a string representing a filename. #The file corresponding to that filename will be a list #of integers, one integer per line. find_median should #return the medi
Answer:
Explanation:
The following is written in Python. It takes in a file, it then reads all of the elements in the file and adds them to a list called myList. Then it sorts the list and uses the elements in that list to calculate the median. Once the median is calculated it returns it to the user. The code has been tested and the output can be seen in the image below.
def find_median(file):
file = open(file, 'r')
mylist = []
for number in file:
mylist.append(int(number))
numOfElements = len(mylist)
mylist.sort()
print(mylist)
if numOfElements % 2 == 0:
m1 = numOfElements / 2
m2 = (numOfElements / 2) + 1
m1 = int(m1) - 1
m2 = int(m2) - 1
median = (mylist[m1] + mylist[m2]) / 2
else:
m = (numOfElements + 1) / 2
m = int(m) - 1
median = mylist[m]
return median
print("Median: " + str(find_median('file1.txt')))
The trackpad/touchpad on my laptop is acting unusual. When I click on something or move to an area, it jumps or moves to another area. What would be a good troubleshooting step to try and resolve this issue?
a. Use a mouse instead
b. Remove all possible contact points, and test again while ensuring only a single contact point
c. Refer caller to user guides
d. increase the brightness of the display
Answer:
My best answer would be, "b. Remove all possible contact points, and test again while ensuring only a single contact point"
This is because usually when the cursor jumps around without reason, it's caused by the user accidentally hitting the mouse touchpad on his or her laptop while typing. ... Similarly, know that just because you have an external mouse attached to your laptop, the built-in mousepad is not automatically disabled.

Mario is giving an informative presentation about methods for analyzing big datasets. He starts with the very basics, like what a big dataset is and why researchers would want to analyze them. The problem is that his audience consists primarily of researchers who have worked with big data before, so this information isn’t useful to them. Which key issue mentioned in the textbook did Mario fail to consider?
Answer:
Audience knowledge level
Explanation:
The Key issue that Mario failed to consider when preparing for her presentation is known as Audience knowledge level.
Because Audience knowledge level comprises educating your audience with extensive information about the topic been presented. she actually tried in doing this but she was educating/presenting to the wrong audience ( People who are more knowledgeable than her on the topic ). she should have considered presenting a topic slightly different in order to motivate the audience.
Does the estimate of a tolerance level of 68.26% of all patient waiting times provide evidence that at least two-thirds of all patients will have to wait less than 8 minutes?
Answer:
Yes, because the upper limit is less Than 8 minutes
Explanation:
According to the empirical formula :
68.26% of data lies within 1 standard deviation from the mean;
Hence,
Mean ± 1(standard deviation)
The sample mean and sample standard deviation of the given data is :
Sample mean, xbar = Σx / n = 546 / 100 = 5.46
Sample standard deviation, s = 2.475 (Calculator)
The interval which lies within 68.26% (1 standard deviation is) ;
Lower = (5.460 - 2.475) = 2.985
Upper = (5.460 + 2.475) = 7.935
(2.985 ; 7.935)
Since the interval falls within ; (2.985 ; 7.935) whose upper level is less than 8 means patients will have to wait less Than 8 minutes.

Imagine that you wanted to write a program that asks the user to enter in 5 grade values. The user may or may not enter valid grades, and you want to ensure that you obtain 5 valid values from the user. Which nested loop structure would you use?
A. A "for" loop inside of a "while" loop
B. A "while" loop inside of a "for" loop
C. None of the above
D. Either a or b would work
The type of nested loop which I would use to write the program is:
B. A "while" loop inside of a "for" loopWhat is a Loop?This refers to the control flow statement which is used to iterate and lets a particular line(s) of code execute repeatedly
With this in mind, we can see that the type of nested loop which I would use to write the program is a "while" loop inside of a "for" loop because it is a conditional statement that continues to ask for the certain valid grades until it gets the right one.
Therefore, the correct answer is option B
