Use the table to answer the question.
Can Swim Cannot Swim Totals
7th Graders 15 60
8th Graders 45
Totals 65 40 105
The table shows data for seventh and eighth graders who can and cannot swim. How would you construct the missing parts of the two-way table?

To construct the missing parts of the two-way table, we need to calculate the total number of eighth graders who can swim and who cannot swim.
To find the total number of eighth graders who can swim:
Total number who can swim = Total number who can swim - Number of seventh graders who can swim
Total number who can swim = 65 - 15
Total number who can swim = 50
To find the total number of eighth graders who cannot swim:
Total number who cannot swim = Total number who cannot swim - Number of seventh graders who cannot swim
Total number who cannot swim = 40 - 60
Total number who cannot swim = -20 (This means that there might be an error in the data provided or the table was constructed incorrectly)
Therefore, the corrected table should look like this:
Can Swim Cannot Swim Totals
7th Graders 15 60 75
8th Graders 50 -10 40
Totals 65 50 105
