3.14 LAB: Simple statistics for Python
Given 4 floating-point numbers. Use a string formatting expression with conversion specifiers to output their product and their average as integers (rounded), then as floating-point numbers.
Output each rounded integer using the following:
print('{:.0f}'.format(your_value))
Output each floating-point value with three digits after the decimal point, which can be achieved as follows:
print('{:.3f}'.format(your_value))
Ex: If the input is:
8.3
10.4
5.0
4.8
the output is:
2072 7
2071.680 7.125
So far I came up with the following:
num1 = float(input())
num2 = float(input())
num3 = float(input())
num4 = float(input())
avg = (num1+num2+num3+num4)/4
prod = num1*num2*num3*num4
print('%d %d'%(avg,prod))
print('%0.3f %0.3f'%(avg,prod))
I keep getting this output and I don't know what I'm doing wrong:
7 2071
7.125 2071.680
Expected output should be:
2072 7
2071.680 7.125

Following are the correct python code to this question:
Program Explanation:
In the python program four variable "n1, n2, n3, and n4" is defined, in which we input method is used that input value from the user end. In this, we use the float method, which converts all the input values into a float value.In the next step, two variables "average and product" are defined, which calculate all input numbers product, average, and hold value in its variable.In the last step, a print method is used, that prints its round and format method value.Program:
n1 = float(input('Input first number: '))#input first number
n2 = float(input('Input second number: '))#input second number
n3 = float(input('Input third number: '))#input third number
n4 = float(input('Input fourth number: '))#input fourth number
average = (n1+n2+n3+n4)/4 #calculate input number average
product = n1*n2*n3*n4 # calculate input number product
print('product: {:.0f} average: {:.0f}'.format(round(product),round(average))) #print product and average using round function
print('product: {:.3f} average: {:.3f}'.format(product,average)) #print product and average value

Programming Exercise 8.2 on page 327. Additional details: The size of an array cannot be changed based on user input (dynamic memory allocation), so the matrix should be dimensionsed to the max size ever expected (10 x 10 perhaps). Prompt user to enter N (the size of the N x N matrix). The program should work for any N >= 2. N should not be used anywhere for matrix dimensions. It is only used in for loops to control user input and printing. Note that a 3x3 matrix is really just using the upper corner of the 10x10 matrix. Prompt the user to enter the elements in the matrix row-by-row. Display the NxN matrix. Display the sum of the elements in the major diagonal. The sum should be displayed from the main function, not from the function sumMajorDiagonal. Include a printout of the main program and the function. Include printouts for the test case in the textbook as well as for a 2x2 matrix and a 3x3 matrix.

Create a public non-final class named Larger parameterized by a type T that implements Comparable. (Please use T or the test suite will fail.) You should provide a single instance method named larger that accepts an array of the parameterized type as the first argument and a single value of the parameterized type as the second argument. larger should return true if the second argument is larger than or equal to every value of the array and false otherwise. If either the array or the value are null you should throw an IllegalArgumentException. As an ungraded bonus challenge, see if you can make the compiler warning about unchecked operations go away… (Note that normally we would write this as a class method. Java does support type parameters for static methods, but we aren’t going to cover that in class. So we’ll use an instance method here instead.) Note also that this homework is not due until Friday but was accidentally released Thursday. It does rely on material we will cover Friday. Feel free to wait to complete it then.

A user in the accounting department reports he or she cannot access the invoices that the sales department has placed on the shared drive. This points toward a possible problem with which component of the computer’s operating system? Networking Time-sharing Interrupts Device Driver
Answers
Answer:
Networking.
Explanation:
An operating system which was developed in the 1950s, is a software which acts as an intermediary between the computer hardware and end users.
The functions of an Operating System are; Memory, Device, Process, File, Secondary-Storage and Input/Output management.
The networking component of the computer's operating system ensures that a group of processors don't share memory, clock and hardware devices, instead the processors communicate with each other through the network.
Basically, the network Operating System (OS) runs on a server and provides the capability to serve to manage groups, user, application or program, data, security and any other networking functions.
Hence, the accountant couldn't access the invoices that the sales department placed on the shared drive because of a networking component problem of the computer’s operating system.
Which of the following is a possible disadvantage of recursion?

Answers
Answer:
Recursive solutions can be less efficient than their iterative counterparts
Explanation:
Recursion can be defined or described as a method of solving a problem where the solution depends on solutions to smaller instances of the same problem.
It entails using iteration to ensure that smaller parts of a solution are satisfied towards solving thw overall problem.
Ita major disadvantage seems to be that it seem to be less efficient than their iterative counterparts. This is as a result of concentrating on trying to solve a smaller instances.

Round your answers to two decimal places.
A = 99.7°, C = 20.4º, a = 27.4
Answers
Answer: 37.1
Explanation: The Law of sines states that there is a proportionality between a side of triangle and its correspondent angle, i.e.:
[tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}[/tex]
where:
a, b and c are sides
A, B and C are angles
In the question, there is a triangle with 27.4 as a measure of side a, angles A and C. So, it wants the side c:
[tex]\frac{a}{sinA} = \frac{c}{sinC}[/tex]
[tex]\frac{27.4}{sin(99.7)} = \frac{c}{sin(20.4)}[/tex]
c = [tex]\frac{27.4.sin(20.4)}{sin(99.7)}[/tex]
c = 37.1
The side c is 37.1

Total kilowatt hours used: 555
Rate for the given usage: $0.6
Total bill: $333
===== BILL FOR GIVEN VALUES =====
Total bill for 900 kilowatt hours: $540
Total bill for 1754 kilowatt hours: $789.3
Total bill for 10000 kilowatt hours: $4500
Explanation:
1. The program takes input from the user for kilowatt hours used.
2. The bill is computed based on the user input.
3. The bill is displayed with three components, kilowatt hours used, rate and the total bill.
4. The bill for the three given values of kilowatt hours is computed and displayed.
Write a program that opens a text file (name the textfile "problem4.txt") and reads its contents into a queue of characters. The user must then enter a character they are looking for. The program should then dequeue each character and count the number of characters that are equal to what the user is looking for. Output the count of the character or lack thereof in a second file (name the textfile "resultsp4.txt").

Question:
When composing an email message:
A) ideas should be organized inductively when the message contains good news or routine information.
B) just be direct, since such communications are routine.
C) present the information in the order it is likely needed or will be best received.
D) avoid repeating information that is in the subject line in the opening sentence.
Answer:
The correct answer is C)
When writing emails, it helps to put ones self in the shoes of the recipient. This helps us to present our thoughts in the way that the recipient will best receive them.
In addition to the above, one must ensure that they go directly to the point, use a courteous tone, and ensure that the message is free from typographical errors whenever he or she is writing an email.
Cheers!
Extra Credit Programming Assignment(7points)Due May 1, midnightWrite a JavaFX application that presents 20 circles, each with a random radius and location. If a circle does not overlap any other circle, fill in the circle with black. Fill in overlapping circles with a translucent blue. Use an array to store the circle objects,and check each new circle to see if it overlaps any previous created circle. Two circles overlap is the distance between their center points is less than the sum of their radii
