Use the data file DemoKTC file to conduct the following analysis. Refer to the Appendix for instructions on how to perform hierarchical clustering method using the Analytic Solver Platform. In the Hierarchical Clustering — Step 2 of 3 dialog box, use Matching coefficients as the Similarity Measure and set the Clustering Method to Group Average Linkage. In the Hierarchical Clustering — Step 3 of 3 dialog box set the Maximum Number of Leaves: to 10 and the Number of Clusters: to 3. Click on the datafile logo to reference the data. (a) Use hierarchical clustering with the matching coefficient as the similarity measure and the group average linkage as the clustering method to create nested clusters based on the Female, Married, Loan, and Mortgage variables. Specify the construction of 3 clusters. How would you characterize each cluster? Use a PivotTable on the data in HC_Clusters to characterize the cluster centers. If your answer is zero enter "0". Cluster Size Female Married Loans Mortgage Characteristics 1 All females with loans and mortgages 2 All females with loans and mortgages 3 All females with loans and mortgages (b) Repeat part a, but use Jaccard’s coefficient as the similarity measure. How would you characterize each cluster? If your answer is zero enter "0".

An airline describes airfare as follows. A normal ticket's base cost is $300. Persons aged 60 or over have a base cost of $290. Children 2 or under have $0 base cost. A carry-on bag costs $10. A first checked bag is free, second is $25, and each additional is $50. Given inputs of age, carry-on (0 or 1), and checked bags (0 or greater), compute the total airfare. Hints: First use an if-else statements to assign airFare with the base cost Use another if statement to update airFare for a carryOn Finally, use another if-else statement to update airFare for checked bags Think carefully about what expression correctly calculates checked bag cost when bags are 3 or more

**GIVING ALL POINTS** 4.02 Coding With Loops
I NEED THIS TO BE DONE FOR ME AS I DONT UNDERSTAND HOW TO DO IT. THANK YOU

Output: Your goal

You will complete a program that asks a user to guess a number.


Part 1: Review the Code

Review the code and locate the comments with missing lines (# Fill in missing code). Copy and paste the code into the Python IDLE. Use the IDLE to fill in the missing lines of code.


On the surface this program seems simple. Allow the player to keep guessing until he/she finds the secret number. But stop and think for a moment. You need a loop to keep running until the player gets the right answer.


Some things to think about as you write your loop:


The loop will only run if the comparison is true.

(e.g., 1 < 0 would not run as it is false but 5 != 10 would run as it is true)

What variables will you need to compare?

What comparison operator will you need to use?

# Heading (name, date, and short description) feel free to use multiple lines


def main():


# Initialize variables

numGuesses = 0

userGuess = -1

secretNum = 5


name = input("Hello! What is your name?")


# Fill in the missing LOOP here.

# This loop will need run until the player has guessed the secret number.


userGuess = int(input("Guess a number between 1 and 20: "))


numGuesses = numGuesses + 1


if (userGuess < secretNum):

print("You guessed " + str(userGuess) + ". Too low.")


if (userGuess > secretNum):

print("You guessed " + str(userGuess) + ". Too high.")


# Fill in missing PRINT statement here.

# Print a single message telling the player:

# That he/she guessed the secret number

# What the secret number was

# How many guesses it took


main()

Part 2: Test Your Code

Use the Python IDLE to test the program.

Using comments, type a heading that includes your name, today’s date, and a short description.

Run your program to ensure it is working properly. Fix any errors you observe.

Example of expected output: The output below is an example of the output from the Guess the Number game. Your specific results will vary based on the input you enter.


Output


Your guessed 10. Too high.

Your guessed 1. Too low.

Your guessed 3. Too low.

Good job, Jax! You guessed my number (5) in 3 tries!




When you've completed filling in your program code, save your work by selecting 'Save' in the Python IDLE.


When you submit your assignment, you will attach this Python file separately.

Please submit one zip file containing all source code, header, and output files. Exercise 1: 30 Points (Duplicate Elimination with vector) Use a vector to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the vector only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Begin with an empty vector and use its pushback function to add each unique value to the vector. SAMPLE RUN: Enter an integer: 105 Enter an integer: 5 Enter an integer: 10 Enter an integer: 11 Enter an integer: 11 Enter an integer: 12 Enter an integer: 13 Enter an integer: 14 Enter an integer: 15 Enter an integer: 15 Enter an integer: 16 Enter an integer: 17 Enter an integer: 18 Enter an integer: 19 Enter an integer: 20 Enter an integer: 21 Enter an integer: 22 Enter an integer: 23 Enter an integer: 24 Enter an integer: 25 Enter an integer: 26
Enter an integer: 27
Enter an integer: 28
Enter an integer: 29
Unique values in the vector are:

In this problem, you will derive the efficiency of a CSMA/CD-like multiple access protocol. In this protocol, time is slotted and all adapters are synchronized to the slots. Unlike slotted ALOHA, however, the length of a slot (in seconds) is much less than a frame time (the time to transmit a frame). Let S be the length of a slot. Suppose all frames are of constant length L = kRS, where R is the transmission rate of the channel and k is a large integer. Suppose there are N nodes, each with an infinite number of frames to send. We also assume that dprop < s,="" so="" that="" all="" nodes="" can="" detect="" a="" collision="" before="" the="" end="" of="" a="" slot="" time.="" the="" protocol="" is="" as="">

⢠If, for a given slot, no node has possession of the channel, all nodes contend for the channel; in particular, each node transmits in the slot with probability p. If exactly one node transmits in the slot, that node takes possession of the channel for the subsequent k â 1 slots and transmits its entire frame.

If some node has possession of the channel, all other nodes refrain from transmitting until the node that possesses the channel has finished transmitting its frame. Once this node has transmitted its frame, all nodes contend for the channel.

Note that the channel alternates between two states: the productive state, which lasts exactly k slots, and the nonproductive state, which lasts for a random number of slots. Clearly, the channel efficiency is the ratio of k/(k + x), where x is the expected number of consecutive unproductive slots

a. For fixed N and p, determine the efficiency of this protocol.
b. For fixed N, determine the p that maximizes the efficiency.
c. Using the p (which is a function of N) found in (b), determine the efficiency as N approaches infinity
d. Show that this efficiency approaches 1 as the frame length becomes large

Write a function that simulates the roll of a six-sided dice. The name of the function is rollDice. The function accepts no parameters and returns a pseudorandom int: 1, 2, 3, 4, 5, or 6. Write only the function, not the main program. You may assume that srand() was invoked in the main function. There should not be any cin or cout statements in the function.

Question 1b
You are provided with two lists of numbers.
• List 'x' denotes all 8 possible dollar investment outcomes of a risky project;
• List 'p' denotes their corresponding outcome probabilities.
• For instance, there is a 5% chance of $10000.
In this question, let's first convert the two lists into two separate arrays. Can you use np.dot to calculate the expected value of this risky project? That is, 10000X0.05+1000X0.05+100X0.2 ... Calculation without using np.dot() will be considered no points.
Finally, print the following sentence using print+format: The expected value of this risky project is $XXX.X.
