Answer:

Both B and C are correct.

Explanation:

In any case, you want the OR (age ≥ 18) in there, because that makes the expression true for people 18 and up. So that already disqualifies answer D.

The most precise answer is B, since it literally states the requirements.

A is incorrect, because learners can be 1 as well, and the age can be 18 as well, so you need ≥ in stead of >.

C is interestingly also correct. The left hand side of the OR would be true for ages over 16 or 17, but that's OK in this case.

When the statement `automobile car = new automobile(1);` is executed, a new instance of the `automobile` class is created with the argument `1`.

Here, `car` is an instance of the `automobile` class and has been assigned the value returned by the constructor method with the argument `1`.

In the above statement, `new automobile(1)` creates a new object of the `automobile` class and then the value of this object is stored in the `car` variable.

The integer argument `1` passed inside the constructor of the `automobile` class is used to initialize the properties of the newly created object.To give you an example, suppose you have a class `automobile` with some properties like make, model, and year.

When you execute the statement `automobile car = new automobile(1);`, you will create a new instance of the `automobile` class, and the properties of this object are initialized according to the value of the integer passed inside the constructor.

The true statement is constructors can be directly inherited from a public base class, but destructors cannot be directly inherited from a public base class.

In object-oriented programming, constructors serve the unique function of initializing objects belonging to a class. It is indeed true that in C++, derived classes can inherit their base class' constructors, even when the inheritance relationship is mutually public. In doing so, a derived class calls its base's constructor directly and applies it to initialize its own data members.

Destructors are equally unique special member functions serving the purpose of cleaning up resources allocated by an object during moments it goes out of scope or is deliberately deleted. Unlike constructors, though, derivate classes cannot inherit destructors directly from their public base classes under any circumstances.

The Entity-Relationship Model (ER Model) is a data model that is used to represent the conceptual schema of a system. It describes the entities, attributes, and relationships between entities in a system.

The ER Model is widely used in database design because it helps to provide a unified view of data in an organization. The ER Model consists of three components: Entities, attributes, and relationships. An entity is anything that is recognizable and unique within a system. An attribute is a characteristic of an entity. It describes a particular aspect of an entity that is of interest to the organization. Relationships describe the associations between entities. They provide a means of capturing the way in which entities relate to each other.

The ER Model is particularly useful because it allows organizations to create a unified view of data. This means that data is consistent and integrated across all systems in the organization. It is also useful because it provides a graphical representation of the data, which can be easily understood by stakeholders. This makes it easier to communicate and share information about the data within the organization.

Line Feed (LF) is a character (represented by the ASCII code 10) that is used to indicate the end of a line of text. It is commonly used in text editors and programming languages. Carriage Return (CR) is a character (represented by ASCII code 13) that is used to indicate the beginning of a new line of text. When LF will be replaced by CRLF, this means that the LF character will be replaced by both the CR and LF characters together. This combination is used to indicate the end of a line of text and the beginning of a new line of text. This is most commonly used in Windows-based systems as it allows for the proper formatting of text files.

Here's a possible implementation of the highest_values function in Python:

def highest_values(values, n):

   sorted_values = sorted(values)

   return sorted_values[-n:]

The function first sorts the input list of values using the sorted function, which returns a new sorted list without modifying the original one.

Then, it selects the last n elements of the sorted list using the slicing syntax [-n:], which returns a new list containing only the last n elements of the original list.

This should output [61, 70, 82], which are the three highest values in the input list [46, 82, 25, 61, 70, 33, 54] sorted in ascending order.

Answer:

Here is the Python program:

small_container = int(input("Enter the number of small containers you recycled?"))

large_container = int(input("Enter the number of large containers you recycled?"))

refund = (small_container * 0.10) + (large_container * 0.25)

print("The total refund for returning the containers is $" + "{0:.2f}".format(float(refund)))

Explanation:

The program first prompts the user to enter the number of small containers. The input value is stored in an integer type variable small_container. The input is basically an integer value.

The program then prompts the user to enter the number of large containers. The input value is stored in an integer type variable large_container. The input is basically an integer value.

refund = (small_container * 0.10) + (large_container * 0.25)  This statement computers the refund that will be recieved for returning the small and larger containers. The small containers holding one litre or less have a $0.10 deposit so the number of small containers is multiplied by 0.10. The large containers holding more than one litre have a $0.25 deposit so the number of large containers is multiplied by 0.25. Now both of these calculated deposits of containers of each side are added to return the refund that will be received for returning these containers. This whole computation is stored in refund variable.

print("The total refund for returning the containers is $" + "{0:.2f}".format(float(refund))) This print statement displays the refund in the format given in the question. The output includes a $ sign and displays exactly two decimal places by using {0:.2f} where .2f means 2 decimal places after the decimal point. Then the output is represented in floating point number using. format(float) is used to specify the output type as float to display a floating point refund value up to 2 decimal places.

The required code which calculates the amount of refund made by returning the containers written in python 3 goes thus :

small_size = eval(input('Enter number of 1L or less containers to be returned: '))

#prompts user to enter the number of small sized containers to be returned

big_size = eval(input('Enter number of containers greater than 1L to be returned: '))

#prompts user to enter the number of big size containers to be returned

small_refund = (small_size * 0.10)

#calculates the total refund on small sized containers

big_refund = (big_size * 0.25)

# calculates the total refund on big size containers

total_refund = float((small_refund + big_refund))

#calculates the Cummulative total refund

print('Your total refund is $' + '{0:.2f}'.format(total_refund))

#displays the total refund rounded to 2 decimal places.
