9.4 Code Practice: Your task is to determine whether each item in the array above is divisible
wariber [46]

Answer:

Explanation:

The following Python code is a function that takes in an array as a parameter, it then loops through the array determining if the element is divisible by 3. If it is it leaves it alone, otherwise it changes it to a 0. Then ouputs the array. A test case is shown in the attached image below using a sample array.

def divisible_by_three(array):

   for x in array:

       if x % 3 == 0:

           pass

       else:

           array[array.index(x)] = 0

   return array

Which is the most likely reason why scientists change a model?
frozen [14]

C.) New discoveries make the current model inaccurate. Since science is all about observation and experimentation, it is logical that whenever new findings are gathered, scientific models must be modified to adapt to the information. As new ideas and concepts are uncovered, models should be updated to make them correct.

should variables that contain numbers always be declared as integer or floating-point data types? why or why not? name potential
Stells [14]

No, it is not necessary that variables that contain numbers should always be declared as integer or floating-point data types.

It is not necessary that variables that contain numbers should be declared as integer and floating point data types. Because number can be declared with different data types.  As we know that data type is a vital aspect in programming. It describes the type of a value that is contained in a variable. It is the data type based on which memory is allocated to a number or any type of variables.

Numbers can be whole decimal/fractional, signed, unsigned, small, and long. Simply, they exist in a variety of values. According to their values range, the amount of memory is reserved.

Different programming languages offer different data types to store numbers, depending on their types and size. Let’s consider some examples of data types used in programming languages in order to declare variables holding numbers.

  • In Python int, float, and complex are the data types used to declare number type variables.
  • SQL uses INTEGER, SMALLINT , BIGINT , NUMERIC() , and DECIMAL() data types for numbers.
  • To deal with number type variables, Java has six predefined data types, such as int, long, short, byte, float, and double.
  • JavaScript uses a single data type called 'number' to declare numbers.
  • In C++, two fundamental data types, int and float, are used to represent numeric variables. But C++ is not only limited to these two data types. The data type char can also store numbers. Other data types for declaring numbers as variables are derived from int, float and char, such as short int, long int, signed int, unsigned int, double, long double, signed char, unsigned char etc. etc.

So in concluding remarks, declaring a number type variable is not only limited to using integers and floating-points data types. Rather it entirely depends on the respective programming language, and size and type of the number to be stored in the variable.
