a. Software Engineering Research Group (SERG) IIUM is organizing a programming competition. Students are allowed to use either Python or C++ programming language for the competition. Student who wishes to opt for Python goes into lab 1 while for C++ in lab 2. The seating arrangement is based on question ID. The number of students that registered for the competition are 10 students only. Each lab has capacity of 13 students. You are required to create a hash table to indicate where each student with the following question IDs (keys) be hashed/mapped to in the slot of the lab (hash table). IDs = {41, 28, 54, 18, 36, 10, 90, 12, 38, 25} using the hash function, h1(ID) = (ID) % lab capacity Show all your calculations and indication to where the values are being hashed.
5 - Cubes Lets assume, that we have a 3D model composed from cubes in standard Euclidean space. In our model, we are using only positive integers. Each of these cubes is defined by its corner with the smallest x, y and z coordinates and by its size. Also each of these boxes have a color. In our case, while we are using only a text mode, it will be a character. You can assume, that the cubes in our model do not overlap, but there can be cubes placed above other cubes. In the code, it will be represented by following type Cube -- Point x y z data Point = Point Int Int Int data Cube = Cube {start::Point, size::Int, color::Char } Write a function view that takes a list of cubes ( [Cube] ) and returns a floor plang (a view from the top). The size of this floor plan will be computed based on the size of the boxes in the input. The result will be a list of strings. Use following function pp to print it on the screen. For the output format, see the sample output bellow. The bottom left corner…
Use the sacramento.csv file to complete the following assignment. Create a file, sacramento.py, that loads the .csv file and runs a logistic regression. The regression should predict whether or not a house has 1 or more than one bathroom based on beds, sqft, and price, in that order.You will need to create a new variable from baths, and it should make it such that those observations of 1 bath correspond to a value of 0, and those with more than 1 bath correspond to a 1. Make sure to add a constant using sm.add_constant(X) Your file should print the results in this way: print(mod.params.round(2)) print(mod.pvalues.round(2)) print('The smallest p-value is for sqft')
Write python code to do the followings 1. Read the attached file "Breast_cancer_dataset.co and store all its columns (except classification) inta a variable (X), and read column "classilication" into a variable (V). Note that if Classification-1 means patient is Healthy, and Classification=2 means patient has Breast cancer 2. Use the package below to train a logistic regression model to learn to predict whether a patient has breast cancer or not using the variables X and Y. from sklearn.linear model iaport Logistietegression 3 Predict the class of a patient. Choose any patient from the input file "Breast cancer_dataset.cs, 4. Compute error in whichever way you prefer. S. Use your model to show the feature/attribute that has the highest impact on Breast cancer. Print the name of the attribute. Explain your findings in one line. The assignment is out of 5 marks. Each one of the above points weighs one grade. Any unnecessary (or extra) lines of code will deduct grades.
a player plays in a single team in a given season. however, the player may change the teams from a season to the next. for a player we keep the name (we want to search based on the last name), the date of birth, the jersey number (which can change when the player changes the team). a coach is hired by a club in a given season. a coach coaches one or more teams per seasons, but at most 3. organize the persons associated with the league in a hierarchy. I need the ERD Model and the relationships ?

You are given a list of projects and a list of dependencies (which is a list of pairs ofprojects, where the second project is dependent on the first project). All of a project's dependencies must be built before the project is. Find a build order that will allow the projects to be built. If there is no valid build order, return an error.EXAMPLEInput:projects: a, b, c, d, e, fdependencies: (a, d), (f, b), (b, d), (f, a), (d, c)Output: f, e, a, b, d, c
Your favorite soccer player is playing in the world cup and the match has ended in a tie. As the teams get ready for the penalty shootout, you know your favorite player will be last to shoot. A quick search tells you that your favorite player makes a goal when kicking from the penalty mark 0.76% of the time. You also know that the player before your favorite player makes a kick from the penalty mark 0.70% of the time. You also know that neither player is impacted by kicks before they take the shot. What is the probability that both players miss their kicks? Report your answer to the second decimal point, that is, 0.45 instead of 0.5.
