Answer:

Explanation:

First, we need to initialize the classifier.

Then, we are required to train the classifier.

The next step is to predict the target.

And finally, we need to evaluate the classifier model.

You will find different algorithms for solving the classification problem. Some of them are like decision tree classification etc.

However, you need to know how these classifier works. And its explained before:

You need to initialize the classifier at first.

All kinds of classifiers in the scikit-learn make use of the method fit(x,y) for fitting the model or the training for the given training set in level y.

The predict(x) returns the y which is the predicted label.And this is prediction.

For evaluating the classifier model- the score(x,y) gives back the certain score for a mentioned test data x as well as the test label y.

Java languageThe cost to ship a package is a flat fee of 75 cents plus 25 cents per pound.1. Declare a constant named CENTS_PER_

Sophie [7]

Answer:

// Here is code in Java.

// import package

import java.util.*;

// class definition

class Main

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

try{

// variables

final int CENTS_PER_POUND = 25;

final int FLAT_FEE_CENTS = 75;

// Scanner object to read input

Scanner sr=new Scanner(System.in);

System.out.print("Enter the shipping weight:");

// read the input weight

int shipWeightPounds=sr.nextInt();

// calculate total cost

int shipCostCents = (shipWeightPounds * CENTS_PER_POUND) + FLAT_FEE_CENTS;

// print Weight

System.out.println("shipping Weight: " + shipWeightPounds);

// print flat fee

System.out.println("flat fee of shipping in cents : " + FLAT_FEE_CENTS);

// print cents per round

System.out.println("Cents/pound for shipping: " + CENTS_PER_POUND);

// print cost of Shipping

System.out.println("total cost of shipping in cents: " + shipCostCents);

}catch(Exception ex){

return;}

}

Explanation:

Declare and initialize two constant variables "CENTS_PER_POUND=25" & "FLAT_FEE_CENTS = 75". Read the input weight from user with the help of Scanner class object. Then calculate the cost of shipping by multiply weight with cent per pound and add flat fee. Then print each of them.

Output:

Enter the shipping weight:12

shipping Weight : 12

flat fee of shipping in cents: 75

Cents/pound for shipping: 25

total cost of shipping in cents: 375

Sphinxa [80]

Answer: Machine learning

Explanation:

The technology that could be combined with the current solution to do this is the machine learning.

Machine learning refers to the use and development of the computer systems which can learn and adapt without them following explicit instructions. This is done through the use of statistical models and algorithms in order to analyse inferences from the patterns in data.

Since the bank wants to streamline their operations for the receiving and processing checks while also enhancing the solution to recognize signs of potential check fraud, then the machine learning can be used.

Initialize the list short_names with strings 'Gus', 'Bob', and 'Zoe'. Sample output for the given program:

ohaa [14]

Answer:

Following are the correct code to this question:

short_names=['Gus','Bob','Zoe']#defining a list short_names that holds string value

print (short_names[0])#print list first element value

print (short_names[1])#print list second element value

print (short_names[2])#print list third element value

Output:

Gus

Bob

Zoe

Explanation:

In the above python program code, a list "short_names" list is declared, that holds three variable that is "Gus, Bob, and Zoe".
In the next step, the print method is used that prints list element value.
In this program, we use the list, which is similar to an array, and both elements index value starting from the 0, that's why in this code we print "0,1, and 2" element value.
