Answer:
rv = "hello"
num_chars = len(rv)
print(num_chars)
Explanation:
*The code is in Python.
Initialize the string rv, in this example I set it to "hello"
Use the len() method to get the number of characters in the rv and set it to the num_chars
Print the num_chars
Note that the result will be 5 in this case, because <em>hello</em> consists of five characters

Answer: Column F
Explanation: In Microsoft excel, for the sake of robustness and to aid the effectiveness of updating formulas across cells. The reference of cells are treated as relative which means that when formulas are copied across columns or within rows, they get updated automatically. However, some numbers may be treated as constants such that we do not want them to change or be updated as we move acisss cells. Thus, such numbers are treated Given absolute references, which is made possible by adding a '$' prefix before the colum alphabet or row number or both. in the scenario given above, the row has the $ prefix, hence, it is absolute and will not change but the column alphabet does not and hence, treated as relative. 
 
        
             
        
        
        
Answer:
a parameter is fixed over time, while an exogenous variable is allowed to change over time.
Explanation:
A parameter can be defined as a value that can be passed to a function. Thus, a parameter refers to a value that must be passed into a function, subroutine or procedure when it is called.
This value can be passed to a function either by reference or by value.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
A variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited. Thus, a variable stores information which is passed from the location of the method call directly to the method that is called by the program.
An exogenous variable can be defined as a that's independent of other variables in a system i.e it's not affected by other variables.
This ultimately implies that, the difference between a parameter and an exogenous variable is that a parameter is fixed over time, while an exogenous variable is allowed to change over time and as such it has a relationship with other variables in a system.
