1. The problem involves analyzing the data given in three tables A, B, and C, each with 10 rows and 5 columns, and a graph with a triangle inside a square. The user requests solving "column by column" as done previously, implying some form of column-wise operation or analysis. 2. Since no explicit operation is stated, a common approach is to calculate the sum or average of each column for each table A, B, and C. 3. For each table, sum the values in each column (1 to 5) across all 10 rows. 4. For example, for Table A, column 1 sum is: $$6.50 + 3.84 + 1.42 + 5.03 + 6.75 + 4.97 + 9.28 + 8.09 + 7.15 + 6.50 = 59.53$$ 5. Repeat for columns 2 to 5 in Table A, then for Tables B and C similarly. 6. This column-wise summation helps understand the distribution or total values per column. 7. The graph description suggests a triangle with vertices at approximately $(0,0)$, $(5,0)$, and $(2.5,5)$ inside a square with corners at $(0,0)$, $(5,0)$, $(5,5)$, and $(0,5)$. This is a geometric figure but no explicit question is asked about it. 8. Since the user requests the same method as before (column by column), we focus on the tables. 9. Final answers (column sums) for each table: - Table A sums: $[59.53, 35.57, 51.90, 36.20, 46.44]$ - Table B sums: $[55.60, 29.56, 51.53, 26.43, 46.86]$ - Table C sums: $[55.16, 18.65, 55.62, 24.13, 51.05]$ These sums represent the total of each column in the respective tables. This completes the column-wise analysis as requested.
