A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set of numbers. Define these functions, median and mode, in a module named stats.py. Also include a function named mean, which computes the average of a set of numbers. Each function should expect a list of numbers as an argument and return a single number. Each function should return 0 if the list is empty. Include a main function that tests the three statistical functions using the following list defined in main:
List: [3, 1, 7, 1, 4, 10]
Mode: 1
Median: 3.5
Mean: 4.33333333333
#Here is the code I am using:
def median(list):
if len(list) == 0:
return 0
list.sort()
midIndex = len(list) / 2
if len(list) % 2 == 1:
return list[midIndex]
else:
return (list[midIndex] + list[midIndex - 1]) / 2
def mean(list):
if len(list) == 0:
return 0
list.sort()
total = 0
for number in list:
total += number
return total / len(list)
def mode(list):
numberDictionary = {}
for digit in list:
number = numberDictionary.get(digit, None)
if number == None:
numberDictionary[digit] = 1
else:
numberDictionary[digit] = number + 1
maxValue = max(numberDictionary.values())
modeList = []
for key in numberDictionary:
if numberDictionary[key] == maxValue:
modeList.append(key)
return modeList
def main():
print ("Mean of [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]: "), mean(range(1, 11))
print ("Mode of [1, 1, 1, 1, 4, 4]:"), mode([1, 1, 1, 1, 4, 4])
print ("Median of [1, 2, 3, 4]:"), median([1, 2, 3, 4])
main()
The Error that I am getting is on Line 14: AttributeError: 'range'object has no attribute 'sort'.
Also on Line 36:
Line36: 10]: "), mean(range1, 11)).

Answer:

In Python:

def median(mylist):

   mylist.sort()

   if len(mylist) % 2 == 1:

       midIndex = int((len(mylist) +1)/ 2)

       print("Median: "+str(mylist[midIndex-1]))

   else:

       midIndex = int((len(mylist))/ 2)

       Mid = (mylist[midIndex] + mylist[midIndex-1] )/2

       print("Median: "+str(Mid))

def mean(mylist):

   isum = 0

   for i in range(len(mylist)):

       isum += mylist[i]

   ave = isum/len(mylist)

   print("Mean: "+str(ave))

   

def mode(mylist):

   print("Mode: "+str(max(set(mylist), key=mylist.count)))

Explanation:

Your program is a bit difficult to read and trace. So, I rewrite the program.

This defines the median function

def median(mylist):

This sorts the list

   mylist.sort()

This checks if the list count is odd

   if len(mylist) % 2 == 1:

If yes, it calculates the mid index

       midIndex = int((len(mylist) +1)/ 2)

And prints the median

       print("Median: "+str(mylist[midIndex-1]))

   else:

If otherwise, it calculates the mid indices

       midIndex = int((len(mylist))/ 2)

       Mid = (mylist[midIndex] + mylist[midIndex-1] )/2

And prints the median

       print("Median: "+str(Mid))

This defines the mean function

def mean(mylist):

This initializes sum to 0

   isum = 0

This iterates through the list

   for i in range(len(mylist)):

This calculates the sum of items in the list

       isum += mylist[i]

This calculates the mean

   ave = isum/len(mylist)

This prints the mean

   print("Mean: "+str(ave))

   

This defines the mode

def mode(mylist):

This calculates and prints the mode using the max function

   print("Mode: "+str(max(set(mylist), key=mylist.count)))

(b) -xy-
(d) - yx​

Answers

Answer:

xy-1

Explanation:

Given expression is :

[tex]x^2-y^2=1[/tex] ..(1)

We need to find the value of [tex]\dfrac{dy}{dx}[/tex].

Differentiating equation (1) wrt x.

[tex]\dfrac{d}{dx}(x^2-y^2)=1\\\\2x-2y\times \dfrac{dy}{dx}=0\\\\2y\times \dfrac{dy}{dx}=2x\\\\y\times \dfrac{dy}{dx}=x\\\\\dfrac{dy}{dx}=\dfrac{x}{y}[/tex]

or

[tex]\dfrac{dy}{dx}=xy^{-1}[/tex]

Hence, the correct option is (c) "xy-1".

C++ "Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. Assume simonPattern and userPattern are always the same length.
Ex: The following patterns yield a userScore of 4:

Answers

Answer:

In C++:

#include <iostream>

using namespace std;

int main(){

   int userScore = 0;

   string simonPattern, userPattern;

   cout<<"Simon Pattern: ";    cin>>simonPattern;

   cout<<"User Pattern: ";    cin>>userPattern;

   for (int i =0; i < simonPattern.length();i++){

       if(simonPattern[i]== userPattern[i]){

           userScore++;        }

       else{            break;        }

   }

   cout<<"Your value: "<<userScore;

   return 0;

}

Explanation:

This initializes user score to 0

   int userScore = 0;

This declares simonPattern and userPattern as string

   string simonPattern, userPattern;

This gets input for simonPattern

   cout<<"Simon Pattern: ";    cin>>simonPattern;

This gets input for userPattern

   cout<<"User Pattern: ";    cin>>userPattern;

This iterates through each string

   for (int i =0; i < simonPattern.length();i++){

This checks for matching characters

       if(simonPattern[i]== userPattern[i]){

           userScore++;        }

This breaks the loop, if the characters mismatch

       else{            break;        }

   }

This prints the number of consecutive matches

   cout<<"Your value: "<<userScore;

Description
Military time uses 24 hours for the entire day instead of 12 for am/pm separately. Military time is a 4 digit (base-10) integer with the following rules:
The first two digits show the hour (between 00 and 23) and
The last two digits show the minutes (between 00 and 59)
There is no colon separating hours from minutes.
Military time starts at 0000 in the morning and counts up
When we get to the afternoon, we use 1300 for 1:00 PM and 2300 for 11:00 PM.
When we get to midnight, the hour is 00 (not 24).
TASK: Write a program that reads two times in military format and prints the number of hours and minutes between the two times (See example below).
NOTE: Your program should consider the difference between the times IN THE SAME DAY. For example: The time difference between 2359 and 0000 is 23 hours and 1 minute (NOT 1 minute).
Detailed Requirements
• Compose a written document (MS Word Document) describing your algorithm, feel free include a diagram if you like
• The program should prompt for two times separately, then print the duration of time between (see sample output below).
• The program should check the input for the correct military time format:
. Make sure the hours are between 00 and 23.
. Make sure the minutes are between 00 and 59
. If the validity check fails, it should print an appropriate error and prompt again.
• Your program should use io manipulators to produce military time with leading zeroes. e.g. 9 am should be printed 0900 (not 900).
• More points will be awarded to an implementation that can produce an accurate result regardless of the order of the inputs.
• Do not produce runtime errors that abruptly end your program (crash)
• Include descriptive comments, neat indentation, proper spacing for good readability, and appropriate and consistently named variables.
• Program source should have a comment block at the top with the student name, section, and description of your program.

Answers

Answer:

There are at least five areas that are covered by computer applications, and five of those are business, government, military, manufacturing, and music. There are also other areas such as scientific and the role of technology in our society is growing annually.

Computers have now for several decades brought automation to the table in small, medium, and large businesses. There are word processing and spreadsheet applications for small businesses all the way up to enterprise-wide applications that cover every aspect of a large business such as accounting, inventory, shop floor, management, and feature real-time reporting capability that can give a snapshot glimpse of the financial position of a company at any point in time.

The government has a wide variety of computer applications. Government uses many of the same tools as small to large businesses in desktop type applications and many that are much more advanced that are used in the military.  Manufacturing applications involve computer-aided design and applications that are used to track production from the time a raw material is moved into the warehouse all the way to the production floor and back into the warehouse as a finished good.  

Military only applications include systems that use GPS in missiles to hone in on targets from miles away. There are all kinds of other applications some of which are secret in nature and the public does not become aware of these until a war is underway. Computer applications in music can help to transcribe and compose music as well as provide accompaniment for a musician to practice with.  

Expect the number of computer applications in all of these fields to become more common in the future. Expect many applications to take the place of people to save money in a cash-crunched economy where everyone is looking for more ways to save money and cut costs.
