Number Summary
1. The numbers given are 570, 300, 40, 130, 210, 200, 130, and 130.
2. Since the problem is not explicitly stated, a reasonable assumption is that we may be asked to analyze or summarize these numbers, for example, calculating their sum, mean, or other statistics.
3. First, let's calculate the sum: $$570 + 300 + 40 + 130 + 210 + 200 + 130 + 130 = 1710$$
4. Next, calculate the mean (average): The number of values is 8.
$$\text{Mean} = \frac{1710}{8} = 213.75$$
5. We can also find the median by ordering the numbers: 40, 130, 130, 130, 200, 210, 300, 570.
6. Since there are 8 values, the median is the average of the 4th and 5th values:
$$\frac{130 + 200}{2} = 165$$
7. Lastly, the mode (most frequent number) is 130, appearing 3 times.
8. Summary:
- Sum = 1710
- Mean = 213.75
- Median = 165
- Mode = 130
