Answer:

within the Book class but needs to also be outside of any methods.

Explanation:

If Ben is creating an entire Book class then the instance variable needs to be within the Book class but needs to also be outside of any methods. If Ben places the variable inside a method it can only be used by that method and therefore becomes an instance variable of that method and not the class. By creating it inside the class and outside the methods it can be used every single time a Book object is created. Therefore, creating an instance variable of serialNumber every time.

Data brokers, also known as data suppliers, data fetchers, information brokers, or even data providers are businesses or companies (even individuals) that, on the most basic level, source and aggregate data and information (mostly information that are meant to be confidential or that are in the real sense difficult to get) and then resell them to third parties. These third parties could be other data brokers.  

They collect data and information from a wide range of resources and sources - offline and/or online e.g web access history, bank details, credit card information, official records (such as birth and marriage certificates, driver's licenses).  

Brokers can steal round about any information. Examples of information that brokers legally or illegally steal are full name, residential address, marital status, age, gender, national identification number, bank verification number. Brokers and hackers are siblings.

A couple types of data brokers are:

1. Those for fraud detection

2. Those for risk mitigation  

Hope this helps!

Assume the variable sales references a float value. Write a statement that displays the value rounded to two decimal points.Assu
romanna [79]

Answer:

The statement is as follows:

print("{0:,.1f}".format(number))

Explanation:

Required

Statement to print 1234567.456 as 1,234,567.5

To do this, we make use of the format keyword, and we set the print format in the process.

To round up number to 1 decimal place, we use the following format:

"{0:,.1f}"

To include comma in the thousand place, we simply include a comma sign before the number of decimal place of the output; i.e. before 1

"{0:,.1f}"

So, the print statement is:

print("{0:,.1f}".format(number))
