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?

Can Swim Cannot Swim Totals
7th Graders
15 60
8th Graders
45
Totals 65 40 105
To construct the missing parts of the two-way table, we need to calculate the total number of 8th graders who can swim and the number of 7th graders who cannot swim.
For the 7th graders:
Total number of 7th graders = 65
Number of 7th graders who can swim = 15
Number of 7th graders who cannot swim = Total number of 7th graders - Number of 7th graders who can swim
Number of 7th graders who cannot swim = 65 - 15
Number of 7th graders who cannot swim = 50
So, the missing part for 7th graders who cannot swim is 50.
For the 8th graders:
Total number of 8th graders = 40
Number of 7th graders = 15
Number of 8th graders who cannot swim = Total number of 8th graders - Number of 8th graders who can swim
Number of 8th graders who cannot swim = 40 - 15
Number of 8th graders who cannot swim = 25
So, the missing part for 8th graders who cannot swim is 25.
The complete two-way table is:
Can Swim Cannot Swim Totals
7th Graders 15 50 65
8th Graders 25 45
Totals 40 105 105
