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?

Answers

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.

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")

Consider a short, 90-meter link, over which a sender can transmit at a rate of 420 bits/sec in both directions. Suppose that packets containing data are 320,000 bits long, and packets containing only control (e.g. ACK or handshaking) are 240 bits long. Assume that N parallel connections each get 1/ N of the link bandwidth. Now consider the HTTP protocol, and assume that each downloaded object is 300 Kbit long, and the initial downloaded object contains 6 referenced objects from the same sender.

Required:
Would parallel download via parallel instances of non-persistent HTTP make sense in this case? Now consider persistent HTTP. Doyou expect significant gains over the non-persistent case?

Answers

Answer:

Data management is a important tool for data handling.

Explanation:

A good knowledge about the data stricture and data management is a prerequisite for working with codes and algorithms. It helps to identify the techniques for designing the algorithms and data storage in the system. It helps to find out the data hierarchy. Thereby allowing the data management in an efficient and effective way. It can increase the skills in computer programming

Code Example 17-1 class PayCalculator { private: int wages; public: PayCalculator& calculate_wages(double hours, double wages) { this->wages = hours * wages; return *this; } double get_wages() { return wages; } }; (Refer to Code Example 17-1.) What coding technique is illustrated by the following code? PayCalculator calc; double pay = calc.calculate_wages(40, 20.5).get_wages(); a. self-referencing b. function chaining c. dereferencing d. class chaining

Answers

Answer:

The answer is "Option b".

Explanation:

Function chaining is shown by this code, as the functions are called one after the other with one statement. Whenever you want to call a series of methods through an object, that technique is beneficial. Just because of that, you may give the same effect with less code and have a single given value only at top of the leash of operations.

Create a Python dictionary that returns a list of values for each key. The key can be whatever type you want.

Design the dictionary so that it could be useful for something meaningful to you. Create at least three different items in it. Invent the dictionary yourself. Do not copy the design or items from some other source.

Next consider the invert_dict function.

def invert_dict(d):
inverse = dict()
for key in d:
val = d[key]
if val not in inverse:
inverse[val] = [key]
else:
inverse[val].append(key)
return inverse

Modify this function so that it can invert your dictionary. In particular, the function will need to turn each of the list items into separate keys in the inverted dictionary.
Run your modified invert_dict function on your dictionary. Print the original dictionary and the inverted one.
Describe what is useful about your dictionary. Then describe whether the inverted dictionary is useful or meaningful, and why.
