In this question, you will experimentally verify the sensitivity of using a precise Pi to the accuracy of computing area. You need to perform the following activities with Python program:
a. Compute the area of a circle with radius 10 using Pi from the Python Math Module. Assign the area to a variable, say realA.
b. Now compute the area of the circle using the Pi value with precision 1,2, and 3 points after the decimal place. (i.e., Pi = 3.1, 3.14 & 3.141). Then Print the percentage difference between each of the areas calculated using each of these values of Pi and realA.
Answers
Answer:
Follows are the code to this question:
import math as x #import math package
#option a
radius = 10#defining radius variable
print("radius = ", radius)#print radius value
realA = x.pi * radius * radius#calculate the area in realA variable
print("\nrealA = ", realA)#print realA value
#option b
a1 = 3.1 * radius * radius#calculate first area in a1 variable
print("Area 1= ", a1)#print Area
print("Percentage difference= ", ((realA - a1)/realA) * 100) #print difference
a2 = 3.14 * radius * radius#calculate first area in a2 variable
print("Area 2= ", a2)#print Area
print("Percentage difference= ", ((realA - a2)/realA) * 100)#print difference
a3 = 3.141 * radius * radius#calculate first area in a2 variable print("Area 3= ", a3)#print Area
print("Percentage difference= ", ((realA - a3)/realA) * 100) #print difference
Output:
please find the attached file.
Explanation:
In the given Python code, firstly we import the math package after importing the package a "radius" variable is defined, that holds a value 10, in the next step, a "realA" variable is defined that calculate the area value.
In the next step, the "a1, a2, and a3" variable is used, which holds three values, that is "3.1, 3.14, and 3.141", and use the print method to print its percentage difference value.

Explanation:
CAR_SALE (Car_no, Date_sold, Agent_no, Commission_pct, Discount_amt)
Assume that a car may be sold by multiple agents, and hence {Car_no, Agent_no} is the primary key. Therefore, a single car sale may occupy multiple tuples.
Additional dependencies are:
Date_sold → Discount_amt and
Agent_no → Commission_pct
Based on the given primary key, is this relation in 1NF, 2NF, or 3NF? Why or
why not? How would you successively normalize it completely? Provide reasoning for each normalization.
Answers
1NF
In 1NF the relation should follow atomicity that means no repeating groups
In the relation there is no repeating groups
So
the relation is in 1NF
2NF
In 2NF, the relation should be in 1NF and each non prime
attribute must depend on primary key and No Partial dependency
Commission% is functional dependent on Salesperson# which is only part of the primary key.
So
relation is not in 2NF
3NF
In 3NF, the relation should be in 2NF and any NON prime attribute should not describe any non prime attribute.
Already we know relation is not in 2NF
there is a non prime attribute date_sold that describe another non prime attribute Discount_amt,
the relation is not in 3NF
Finally we come to. Know
the relation satisfies only 1NF
NORMALIZATION
The relation is not in 2NF
Decompose the relation CAR_SALE
CAR_SALES (Car#, Date_sold, Salesperson#, Discount_amt)
SALESCOMM (Salesperson#, Commission%)
CAR_SALES and SALESCOMM are in 2NF
In 3NF, the relation should be in 2NF and any NON prime
attribute should not describe any other non prime attribute
SALESCOMM relation is in 3NF
but CAR_SALES is not in 3NF the reason is that there is a
non prime attribute Date_sold that describes another non prime attribute Discount_amt.
So, decomposing the relation
CARSALEDATE (car#, salesperson#, Date_sold)
DATEDISS(Date_sold, discount_amt)
The relations CARSALEDATE
SALESCOMM
DATEDIS are in 3NF

Alice has an item x and Bob has a set of five distinct items y1, y2, y3, y4 and y5. Design a protocol through which Alice (but not Bob) finds out whether her x equals any of Bob's five items; Alice should not find out anything other than the answer ("Yes" or "No") to the above question, and Bob should not know that answer or any secret from Alice. Do not use a hash-based solution because even though the probability of a colission is small, Alice requires that no such colission can occur (but using encryption is fine, because in that case two distinct items that are encrypted with the same key will result in two different ciphertexts).
NOTE: THE SOLUTION FOR THIS SHOULD BE MATHEMATICALLY EXACT.
Answers
The protocol shows that the items of Alice = {x} and the items of Bob = {y1, y2, y3, y4, y5}
How to depict the protocolThe ways to design the protocol will be:
Alice will get Bob's public key.Alice will send a communication to Bob encrypted through Bob's community key.Bob's motivation has a clandestine key.Through the top-secret key, Bob will try to work out the communication.Bob will give a response called yes or no.Bob doesn't know what substances are with Alice.If Alice Alice gets any of the responses as yes then Alice's item is equivalent to any of Bob's five items.If Alice's items are not equal to Bob's items then Alice will get a response as no.It should be noted that protocol is important for relaying datagrams across the network boundaries.

What will be the output of the following program? Assume the user responds with a 2.
answer = input ("How many books would you like? ")
priceBook = 3.20
intNumberBooks = float(answer)
moneyDue = intNumberBooks * priceBook
print ("You owe $", moneyDue)
A) You owe $ 6.40
B) An error occurs.
C) You owe $6.40
D) You owe $moneyDue
Answers
Answer:
A or C (depends on your programming language)
Explanation:
When someone replies to the input, "answer" is set to a string containing their reply -- in this case, 2. intNumberBooks is set to the floating-point value of "answer" (which is actually strange, since "int" implies an integer). So if the user responds with 2, intNumberBooks = 2. moneyDue then is set to the price times the number of books:
moneyDue = 2 * 3.20
So it will print moneyDue of $6.40. Whether the answer is A or C, though, depends on the programming language you're using -- I can't tell whether it will print a space after the $ or not, unfortunately.
The output of the given program if assuming the user responds with a 2 is You owe $6.40. The correct option is A.
What is the output?Data input is required for programs. The program uses (processes) this data, and as a result, data (or information) is output. Any information that a program or other electronic device processes and sends out is considered its output. The output is anything that can be seen on the computer screen, such as the words you type on the keyboard.
When someone responds to an input, the floating-point value of "answer" in number books is set to a string expressing their response, in this case, 2.
Therefore, if the user replies with 2, the money owing is set to the price multiplied by the number of books:
Money Due = 2 x 3.20 = $6.40
Therefore, the correct option is A. You owe $ 6.40.

This may be more costly though but it would be helpful for data recovery without requiring physical data transmission
