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?

7th Graders
15 60
8th Graders
45
Totals 65 40 105
To complete the missing parts of the two-way table, we need to first calculate the totals for the 7th graders who cannot swim and then calculate the totals for the 8th graders who can swim.
For 7th graders who cannot swim:
Total 7th Graders = 75
15 (Can Swim) + 60 (Cannot Swim) = 75
Now, we can find the missing part of the table:
7th Graders Can Swim Cannot Swim Totals
15 60 75
For 8th graders who can swim:
Total 8th Graders = 70
65 (Can Swim) + 45 = 70
Now, we can complete the table:
8th Graders Can Swim Cannot Swim Totals
65 45 70
