Alright, let's go through the steps carefully to solve the given problem.
### Step-by-Step Solution:
1. Identify Selected Numbers:
The numbers you need to use are: 5, 7, 10, 13, 14, 17, 19, and 21.
2. Summing the Selected Numbers:
To find the solution, we need to add these selected numbers together.
Here are the calculations:
- [tex]\(5 + 7 = 12\)[/tex]
- [tex]\(12 + 10 = 22\)[/tex]
- [tex]\(22 + 13 = 35\)[/tex]
- [tex]\(35 + 14 = 49\)[/tex]
- [tex]\(49 + 17 = 66\)[/tex]
- [tex]\(66 + 19 = 85\)[/tex]
- [tex]\(85 + 21 = 106\)[/tex]
3. Verify the Sum:
To ensure accuracy, let's break down the addition into pairs again if needed:
- Adding the first four numbers:
[tex]\[5 + 7 + 10 + 13 = 35\][/tex]
- Adding the next set of numbers to the intermediate result:
[tex]\[35 + 14 + 17 + 19 + 21 = 71\][/tex]
- [tex]\[35 + 71 = 106\][/tex]
Therefore, the summed result of the selected numbers is [tex]\(106\)[/tex].
### Conclusion:
The correct answer from the given options must be:
[tex]\( \boxed{106} \)[/tex]
However, remember to check the provided options. The correct option should sum up to [tex]\(106\)[/tex]. Given the choices:
A. 48 \
B. 522 \
c. 6.38 \
D. 6.1
None of these match the correct sum. Hence, it appears there may be an error in the options provided, as the correct sum of the selected numbers [tex]\(5, 7, 10, 13, 14, 17, 19, \text{and} 21\)[/tex] is indeed [tex]\(106\)[/tex].
