Write a program that asks the user for the name of a text file. The program should display the first 10 lines of the file on the screen. If the file has fewer than 10 lines, the entire file should be displayed along with a message indicating the entire file has been displayed.

Answers

Answer 1

Answer:

Written in Python

filenm = input("File name: ")

myfile = open(filenm+".txt")

for i in range(10):

     line = myfile.readline()

     print(line)

print("End of file")

Explanation:

This line prompts user for file name

filenm = input("File name: ")

This line creates an instance of the file

myfile = open(filenm+".txt")

This line iterates through the 10 lines

for i in range(10):

This line reads the line

     line = myfile.readline()

This line prints each line

     print(line)

This line prints a message indicating that all possible lines have been printed

print("End of file")

Daiki is creating a database for a paint store. Each color of paint would have its own record which will include the color name price and size. The price of the paint will be in its own a) table b) file c) field d) format

Answers

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct answer to this question is c)field.

As we know that the feature of an entity is represented by its attribute in the database table. A database table is a set of records of different fields. Each field represents a row in a database table. Each field can contain a set of attributes related to an entity such as a paint color.

So the price of paint will be in its own field. Because there are different colors in the database table. Each color has its own record in form of a field. As you know that each field is a row in the database table. So, each row has the price of a paint color.

Other options are not correct because:

The table contains a list of fields and each field contains its own paint price. The format and file is something different and does not have any relation with the question scenario.

Answer:

C) Field

What is the cardinality of the power set? 16

What is the power set of A = { }? => {{ }} or {Ф

Explanation:

Given set is:

A = {a,b,c,d}

What is the cardinality of A?

The cardinality of set is the number of elements in the set

Since, set A has four members the cardinality is 4.

i.e.

n(A) = 4

What is the power set of ℘(A)?

The power set of a set consists of all the subsets of a set.

So the power set of A will consist of all subsets of A.

The power set is:

P(A) = {Ф, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,b,d}, {b,c,d}, {a,c,d},{a,b,c,d}}

What is the cardinality of the power set?

The number of subsets of a set is the cardinality of power set.

As A is 4 members,

Cardinality of Power set of A = 2^4 = 16

What is the power set of A = { }

As A is an empty set, its power set will have only one element (Ф) as member

P(A) = {{ }} or {Ф}

Hence,

What is the cardinality of A? 4

What is the power set of ℘(A)? P(A) = {Ф, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,b,d}, {b,c,d}, {a,c,d},{a,b,c,d}}

Given that a computer required​ service, what is the probability that it was a​ laptop? Given that the computer required​ service, the probability that it was a laptop is nothing?

Answers

Complete Question:

A campus bookstore sells both types and in the last semester sold 56% laptops and 44% desktops. Reliability rates for the two types of machines are quite different, however. In the first year, 5% of desktops require service, while 15% of laptops have problems requiring service.

Given that a computer required service, what is the probability that it was a laptop?

Answer:

Probability = 0.084

Explanation:

Given

Laptops = 56%

Desktop = 44%

Service Required (Laptop) = 15%

Service Required (Desktop) = 5%

Required

Determine the probability that a selected computer is a laptop and it requires service.

The question tests our knowledge of probabilities using "and" condition.

What the question requires is that, we calculate the probability of selecting a LAPTOP that REQUIRES SERVICE

Note the capitalised words.

This will be calculated as follows:

Probability = P(Laptop) and P(Service Required (Laptop))

[Substitute values for P(Laptop) and P(Service Required (Laptop))]

Probability = 56% * 15%

[Convert to decimal]

Probability = 0.56 * 0.15

Probability = 0.084
