num = float(input("Enter a number: "))

if num >= 0:

print(num**0.5)

17.

num1 = float(input("Enter the first number: "))

num2 = float(input("Enter the second number: "))

operation = input("Which operation would you like to perform (a/s/m/d): ")

if operation == "a":

print("{} + {} = {}".format(num1, num2, num1+num2))

elif operation == "s":

print("{} - {} = {}".format(num1, num2, num1-num2))

elif operation == "m":

print("{} * {} = {}".format(num1, num2, num1*num2))

elif operation == "d":

print("{} / {} = {}".format(num1, num2, num1/num2))

The answer is algorithm

19.

The correct answer is C

20.

We analyze algorithms to see which algorithm is the best fit for the job.

I hope this helps!

Write a CashRegister class that can be used with the RetailItem class that you wrote in Chapter 6's Programming Challenge 4. The

lys-0071 [83]

Answer:

Following are the code to this question:

import java.util.*; //import package for user input

class RetailItem//defining class RetailItem

{

private String desc;//defining String variable

private int unit;//defining integer variable

private double prices;//defining double variable

RetailItem()//defining default Constructor

{

//Constructor body

}

Output:

The Sub Total value: 199.75

The Sales Tax value: 11.985

The Total value: $211.735

Explanation:

In the above code three class "RetailItem, CashRegister, and Main" is defined, in the class "RetailItem", it defines three variable that is "desc, unit, and prices", inside the class "get and set" method and the constructor is defined, that calculates its value.

In the next step, class "CashRegister" is defined, and inside the class parameterized constructor is defined, which uses the get and set method to return its value.

In the next step, the main class is declared, in the main method two-class object is created and calls its method that are "getSubtotal, getTax, and getTotal".

There is some technical error that's why full code can't be added so, please find the attached file of code.

Gekata [30.6K]

Answer:

It is true, that in a management information system, the quality of information is determined by its usefulness to users, and its usefulness determines the success of the information system.

Explanation:

A management information system (MIS) is a computerized and centralized database that collects data from many different resources in the organization. And, then processes and organized the data in a way that would be useful and helpful in making a business decision. These days, for both large and small organization, collection of data and use of technology are so prevalent and these organization collecting the data from their businesses resources daily even hourly such as daily sale, daily expense, hourly wages, etc, and then managing it in a way to make a right business decision. A good MIS in an organization gives a competitive advantage because it turns the data into usable and into helpful information that can be used in making business decisions and strategy and to increase profit.

However, the information quality is based on its usefulness to the user or to the organization. Because if the MIS produces the information that is not useful to the user, the information and use of MIS are useless in the organization because the information that is required in making a business decision is not useful.

If the MIS produces the quality information to its user in making the right business decision and organization or user take the right decision that brings profit to the organization. Then, this use of information determines the success of an information system in an organization.

For example:

In a Bakery, the MIS produce the right information in making decision e.g. MIS produce information to bakery owner that on valentine day, most people buy chocolate. Then, the owner tries to meet the demand for chocolate on valentine's day. Therefore, this is the quality of information and it is determined by its usefulness to the bakery owner and its usefulness determines the success of MIS.

Answer:

Check the explanation

Explanation:

from Employee import *

def unpickle_employee(filename):

file=open(filename,'rb')

data=pickle.load(file)

file.close()

return data

def pickle_employee(data,filename):

file=open(filename,'wb')

pickle.dump(data,file)

file.close()

if __name__=='__main__':

filename="Employees.dat"

'''

E=Employee("Ajay",1,"R&D","Manager")

data={}

data[1]=E

pickle_employee(data,filename)

'''

data=unpickle_employee(filename)

while True:

print("\nData In Employee.dat")

for d in data:

print("Employe data: ",data[d].get_name(),"({},{},{})".

format(data[d].get_id_number(),data[d].get_department(),data[d].get_job_title()))

print("\n\n\t\tMenu")

print("To add new Employee, Enter a")

print("To update any Employee, Enter u")

print("To delete any Employee, Enter d")

print("Enter anything to quit")

choice=input("Enter: ")

if choice=='a':

id_number=random.randrange(100,200,1)

while id_number in data:

id_number+=1

The purpose of this assignment is to determine a set of test cases knowing only the functionâ€™s specifications, reported hereaf

Nesterboy [21]

Answer:

The program is written using PYTHON SCRIPT below;

N=int(input(" Enter number of Rows you want:"))

M=[] # this for storing the matrix

for i in range(N):

l=list(map(int,input("Enter the "+str(i+1)+" Row :").split()))

M.append(l)

print("The 2D Matrix is:\n")

for i in range(N):

print(end="\t")

print(M[i])

W=[] # to store the first non zero elemnt index

T=[] # to store that value is positive or negative

L=len(M[0])

for i in range(N):

for j in range(L):

if (M[i][j]==0):

continue

else:

W.append(j) # If the value is non zero append that postion to position list(W)

if(M[i][j]>0): #For checking it is positive or negative

T.append(+1)

else:

T.append(-1)

break

print()

print("The first Non Zero element List [W] : ",end="")

print(W)

print("Positive or Negative List [T] : ",end="")

print(T)

Explanation:

In order for the program to determine a set of test cases it takes in input of 2D matrix in an N numbet of rows.

It goes ahead to program and find the column index of the first non-zero value for each row in the matrix A, and also determines if that non-zero value is positive or negative. The If - Else conditions are met accordingly in running the program.
