Answer:

Number classes that received pack of books = n classes

Explanation:

Question:

There are n classes in a school, each with a different number of students. The school receives m packs of books, each with a different number of books. For a class to receive a pack, the number of students in that class must be equal to the number of books in the pack. Determine how many classes receive a pack of books.

Solution:

n = number of classes

m = number of pack of books

The above question didn't give the number of students in each class. Neither did it give the number of books in each pack. We would make assumptions in order to derive our answer.

Assumption 1: That the number of pack of books received corresponds to the number of classes in the school.

That is m = n .

Assumption 2:

That the number of students in each class corresponds to the number of books in each packs.

That is, If number of students are: 10, 15,20,25,30.

Each number of books in the each pack would be in that amount: 10, 15,20,25,30.

Since it is stated that for a class to receive a pack, the number of students in that class must be equal to the number of books in the pack.

Hence all classes would receive a

Pack of book based on our assumption.

Number classes that received pack of books = m classes

Note: A change in assumption would change the answer derived. For instance, if m is not equal to m and number of students not equal to number of packs, the answer would be different from the one we obtained above.

Suppose you have the following declaration.int[] beta = new int[50];Which of the following is a valid element of beta.(i) beta[0

kompoz [17]

Answer:

The answer is "Option (i)".

Explanation:

In the given question, an array is defined. It is a collection of the same type of data element, which means, array stores either a numeric value or string value at a time.
An array beta is defined, which contains 50 elements. The array elements indexing always starts with 0 which means, the first element of the array will be stored in an index value that is 0. That's why option (i) is correct.

In a single file, you wrote a bike class and used this line of code in the program.

Elza [17]

Answer:

Explanation:

Based on the available options the one that would be correct would be that the code to define your class (beginning with "class bike") must come before the line "bikeA = bike('Acme' 111)." This is because the line of code declaring the object and initializing it needs to be able to grab the information of the class that it is creating an object of. To do this, the class would need to have already been compiled by the program. It is good practice to have each class definitions as its own separate files but this is not a necessity.
