Final answer:
The outputs after inputting 9 are A, C, and D. For the input of 8, no letter is specified, though C would be logically expected. Inputting 13 results in A, (presumed B), and D. The symbol to check if x is not less than 17 is >=.
Step-by-step explanation:
When analyzing the provided code, it appears it contains several conditions that check the input number against certain criteria and prints a corresponding letter based on the result.
Question #1: Output for number 9
If the user inputs 9, the conditions will result in the following outputs:
A is printed because 9 is not equal to 8.
C is printed because 9 is less than 10.
D is printed because 9 is an odd number (9 % 2 equals 1).
Question #2: Output for number 8
If the user inputs the number 8, only one condition is satisfied:
A is not printed because 8 is equal to 8, so the condition fails.
B and D conditions depend on variables or values that are not defined in the provided context.
C is printed because 8 is less than 10.
Question #3: Output for number 13
For the number 13, the following outcomes will occur:
A is printed because 13 is not equal to 8.
B is printed because 13 is greater than or equal to 10.
D is printed because 13 is an odd number (13 % 2 equals 1).
Question #4: Correct Symbol for Testing if x is NOT less than 17
The correct symbol to complete the condition to test if x is not less than 17 is \u0027>=\u0027.
