Final answer:
The output of the input/output machine when the input is divided by 4 is 8.
Step-by-step explanation:
To find the output of the input/output machine when the input is divided by 4, we divide the given input by 4. The options given are 10, 9, 8, and 7. Let's check each option:
- 10 ÷ 4 = 2.5
- 9 ÷ 4 = 2.25
- 8 ÷ 4 = 2
- 7 ÷ 4 = 1.75
Out of the options, the only option that gives a whole number when divided by 4 is 8. Therefore, the correct answer is 3) 8.
