TODO 2 Complete the TODO by finding the locations of the data samples for each iris flower type. Hint: Use the code for how we found all the setosa_locs as an example! Using iris_df, find the location of all the data sample locations for the versicolor class which has a label of 1. To do so, use NumPy's np.where() function. Using iris_df, find the location of all the data sample locations for the virginica class which has a label of 2. To do so, use NumPy's np.where() function. setosa_locs = np.where(iris_df['class'] == 0)[0] # TODO 2.1versicolor_locs = # TODO 2.2virginica_locs = todo_check([ (type(versicolor_locs) is np.ndarray, "'versicolor_locs' is not type np.ndarray.

Assume that all eight sides of the Comparableand Cloneable inter-be computed useing the fllowing formula : area =(2 + 4 / square root of 2)* side * side Draw the UML diagram that involves Octagon, GeomtricObject,Comparable and Cloneable. Write a test program that create a new Object using the clone method and comoare the two object using the compareTo method.

This question involves the design of a class that will be used to produce practice problems. The following StudyPracticeinterface represents practice problems that can be used to study some subject. public interface StudyPractice. { /**Returns the current practive problem */ String getProblem(); /** Changes to the next practice problem */ void nextProblem(); } The MultPractice class is a StudyPracticethat produces multiplication practice problems. A MultPractice object is constructed with two integer values: first integer and initial second integer. The first integer is a value that remains constant and is used as the first integer in every practice problem. The initial second integer is used as the starting value for the second integer in the practice problems. This second value is incremented for each additional practice problem that is produced by the class. For example, a MultPractice object created with the call new MultPractice (7, 3)would be used to create the practice…
Write a c++ oop code following these instructions only. Class Scene: capture_date : int draw() : void // Abstract method Class Landscape: area : double render(): void Class FlightSimulator: It has aggregation relationship with abstract class Redefine draw() function that has only a print statement of “Drawing Scene”. Class MountainScene: Call render function of Landscape as mentioned in diagram. (a) Add a function getArea() in 'Scene' class. Class Scene: capture_date : int draw() : void // Abstract method getArea() : string // Displays 'Area of Scene' Class CityScene: draw() : void getArea() : string // Displays 'Area of City Scene' Class MountainScene: draw() : void getArea() : string // Displays 'Area of Mountain Scene' (b) 1- Create a pointer of Scene class 2- Assign object of MountainScene class to the pointer created in part 1 3- Call getArea() through the pointer 4- Report the output you get in part 3
ONLY PYTHON CODE! Crops grow only when the Nitrogen is within a particular range. Construct a crop class that will take the name of a crop, its lower Nitrogen value, and its higher Nitrogen value: Raspberry – Nitrogen content b/n 1 and 3 Apple – Nitrogen content b/n 1 and 4 Squash – Nitrogen content b/n 2.5 and 4 Pumpkin – Nitrogen content b/n 3 and 5 Onion – Nitrogen content b/n 2.5 and 5 Create 4 fields of farm land: f1, f2, f3, and f4, using Python classes that have a Nitrogen content of 1, 2, 3, and 4 respectively. Then, create a function in the field code that will take a crop and return if it will be able to grow in the field or not. Create a list for each crop that tells the farmer which plot they could plant the crop in. Ouput: Raspberry can be planted in f1 Raspberry can be planted in f2 Raspberry can be planted in f3 Apple can be planted in f1 Apple can be planted in f2 Apple can be planted in f3 Apple can be planted in f4 Squash can be planted in f3 Squash can be planted…
This is the question - Create an abstract NewspaperSubscription class with fields for the subscriber name, address, and rate. Include get and set methods for the name field and get methods for the address and subscription rate; the setAddress() method is abstract. Create two subclasses named PhysicalNewspaperSubscription and OnlineNewspaperSubscription. The parameter for the setAddress() method of the PhysicalNewspaperSubscription class must contain at least one digit; otherwise, an error message is displayed and the subscription rate is set to 0. If the address is valid, the subscription rate is assigned $15. The parameter for the setAddress() method of the OnlineNewspaperSubscription class must contain an at sign (@) or an error message is displayed. If the address is valid, the subscription rate is assigned $9. Code I was given - public class DemoSubscriptions { public static void main(String args[]) { PhysicalNewspaperSubscription pnsGood = new…
Please help with this problem ASAP! Create a class definition named Substance that can set and read the Substance’s name andmass (in kilograms) and compare 2 Substance objects with the less_than function. Create aclass definition named Fluid that inherits Substance and can set and get the Fluid’s viscosity(how thick it is) from 0.0 to 1.0. Then create an Ink class definition and implementationwhich inherits Fluid and can set and get the Ink’s color (red 00-FF, green 00-FF, blue 00-FF)as a HEX triplet string. A passed color should be validated; it must be 6 characters long andonly contain the “0123456789ABCDEF” characters.
