Working together, printer A and printer B would finish the task in 24 minutes. Printer A alone would finish the task in 60 minut
sasho [114]

Answer:

The correct answer to this question is option (1).

Explanation:

Let x1 = Is number of pages that printer A can print  in page/minute.  

thus x1 + 5 = Is number of page that printer B can print in page/minute.  

As printer A finishes his work in 60 min. So the task has 60x1 pages. As printers A and B both finish that task in 24 minutes. So the equation can be given as:  

60x1 = 24x1 + 24(x1 + 5)  

 

60x1 = 24x1 + 24x1 + 120  

 

60x1=48x1 + 120

 

60x1-48x1=120

 

12x1=120  

 

x1=120/12

 

x1=10

put the value of x1 in to (60x1). Therefore, the task has 60(10) = 600 pages. the task contains 600 pages.  

So the answer to this question is option (1).

Write a method called removeHighPrice that will go through a provided ArrayList called prices and removes the first price that i
Diano4ka-milaya [45]

Answer:

The method written in Java is as follows:

public static ArrayList<Double> removeHighPrice (ArrayList<Double> prices){

       for(int i =0;i<prices.size();i++){

     if(prices.get(i) > 5.00){

         prices.remove(i);  

         break;

     }

 }

 return(prices);  

 }

Explanation:

This line declares the method

public static ArrayList<Double> removeHighPrice (ArrayList<Double> prices){

This line iterates through the ArrayList named prices

       for(int i =0;i<prices.size();i++){

This checks if current price is greater than 5

     if(prices.get(i) > 5.00){

If yes, the price is removed

         prices.remove(i);  

And the loop is terminated

         break;

     }

 }

This returns the ArrayList

 return(prices);  

 }

Create a new data frame, first_south, by subsetting titanic to include instances where a passenger is in the first class cabin (
Virty [35]

The data frame first_south is created using first_south = (titanic['Pclass']==1) & (titanic['Embarked']=='S')

<h3>How to create the data frame?</h3>

To do this, we make the following assumptions:

  • The pandas module has been loaded as pd
  • The dataset has also been loaded as titanic

When pclass column is 1.

This is represented as:

titanic['pclass']==1

When the passenger boards from Southampton.

This is represented as:

titanic['Embarked']=='S'

So, we have:

first_south = (titanic['Pclass']==1) & (titanic['Embarked']=='S')
