To analyze the two methods based on the data provided in the table, we first observe the success rates for each method over the days.
**Method A:**
- The values are 1, 3, 5, 7, 9, 11, 13, 15.
- The differences between consecutive days are constant (2 each day: 3-1=2, 5-3=2, etc.).
- This indicates a linear relationship.
**Method B:**
- The values are 7, 3, 1, 1, 3, 7, 13, 21.
- The differences between consecutive days are not constant:
- 3 - 7 = -4
- 1 - 3 = -2
- 1 - 1 = 0
- 3 - 1 = 2
- 7 - 3 = 4
- 13 - 7 = 6
- 21 - 13 = 8
- The differences are not constant, and they appear to show increasing patterns, suggesting a quadratic relationship.
Based on this analysis:
- Method A should be modeled with a **linear equation**.
- Method B should be modeled with a **quadratic equation**.
Therefore, the correct response is:
**Method A should be modeled with a linear equation, and Method B should be modeled with a quadratic equation.**
