Answer:
By supplying a variety of charts and graphs to present the information in best way.
By tracking and analyzing the data
By conveying large amount of numerical data in more understandable format.
Explanation:
You need to know the limitations of Excel software. You will find that it does not support more than 3 variables while analyzing. However, if you use analytic software like Tableau and Microsoft Power BI then you can use a lot number of variables. And this is done through graphs and charts, and the other variables apart from x, y, z are the colors, shades. etc. Even color alone can add a good number of variables, and hence you can understand. Thus, you will be able to query better. Queries become better if you have more variables. And charts and graphs always present the information in the best way/ Also you can track and analyze the data. And through it conveying a large amount of numerical data in a more understandable format is made possible, and this is definitely quite helpful. Hence, all of the options mentioned above are helpful. But they do not do complex calculations and complex queries in fact.
Answer:
B. string -> (int -> int)
Explanation:
We are going to perform comparison operations '->'. It is important to notice that the comparison operation gives us a bool value (True or False) and the comparison operation is legal if and only if the data types to be compared are the same.
Example:
int(4)->int(5) False
int(4)->int(4) True
int(4)->string(4) Error, data types don't match
For this reason:
- A. Is legal because float -> float evaluates to True, True is a boolean value and bool -> bool is legal because both are the same data type.
- B. Is illegal because int -> int evaluates to True, True is a boolean value and string is not a boolean (string -> bool).
- C. Is legal because int is the same type than int.
- D. Is legal because the list is the same type than list regardless it's content.
Note:
The operations inside parentheses are evaluated first.
List is a type by itself regardless of its content.
