Write a program that creates an an array large enough to hold 200 test scores between 55 and 99. Use a Random Number to populate the array.Then do the following:1) Sort scores in ascending order.2) List your scores in rows of ten(10) values.3) Calculate the Mean for the distribution.4) Calculate the Variance for the distribution.5) Calculate the Median for the distribution.
Answers
Answer:
Explanation:
The following code is written in Python. It uses the numpy import to calculate all of the necessary values as requested in the question and the random import to generate random test scores. Once the array is populated using a for loop with random integers, the array is sorted and the Mean, Variance, and Median are calculated. Finally The sorted array is printed along with all the calculations. The program has been tested and the output can be seen below.
from random import randint
import numpy as np
test_scores = []
for x in range(200):
test_scores.append(randint(55, 99))
sorted_test_scores = sorted(test_scores)
count = 0
print("Scores in Rows of 10: ", end="\n")
for score in sorted_test_scores:
if count < 10:
print(str(score), end= " ")
count += 1
else:
print('\n' + str(score), end= " ")
count = 1
mean = np.mean(sorted_test_scores)
variance = np.var(sorted_test_scores, dtype = np.float64)
median = np.median(sorted_test_scores)
print("\n")
print("Mean: " + str(mean), end="\n")
print("Variance: " + str(variance), end="\n")
print("Median: " + str(median), end="\n")

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
Answers
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.

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

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
Answers
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.

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
Answers
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.

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?
Answers
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.

Answers
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]
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.
Answers
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))
