1. The problem is to create a table of participants including columns for $x$, $y$, $xy$, $x^2$, and $y^2$. 2. The formulas for each column are: - $xy = x \times y$ - $x^2 = x \times x$ - $y^2 = y \times y$ 3. To create the table, you need to have values for $x$ and $y$ for each participant. 4. For each participant, calculate $xy$, $x^2$, and $y^2$ using the formulas above. 5. Organize the data in a table format with columns labeled $x$, $y$, $xy$, $x^2$, and $y^2$. Since no specific data was provided, here is an example with sample values: | $x$ | $y$ | $xy$ | $x^2$ | $y^2$ | |-----|-----|------|-------|-------| | 1 | 2 | 2 | 1 | 4 | | 3 | 4 | 12 | 9 | 16 | | 5 | 6 | 30 | 25 | 36 | This table shows how to compute each column based on $x$ and $y$ values. Final answer: Use the formulas $xy = x \times y$, $x^2 = x^2$, and $y^2 = y^2$ to fill the table for each participant.
