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 15 60
8th Graders 45 45 45
Totals 65 40 105
To construct the missing parts of the two-way table, we need to distribute the total values for each row and column.
For the 7th Graders row, since the total is 60, and 15 students can swim, we would subtract 15 from 60 to get the number of students that cannot swim (60 - 15 = 45).
For the 8th Graders row, since the total is 45, and 45 students cannot swim, we know that all the remaining students (45) must be able to swim.
For the Can Swim column, the total number of students who can swim is 65, so we can add up the number of 7th and 8th graders who can swim to get our total of 65 (15+50=65).
For the Cannot Swim column, the total number of students who cannot swim is 40. Since we already calculated that 45 7th graders and 45 8th graders cannot swim, the total must be 40.
Therefore, the completed two-way table should look like this:
Can Swim Cannot Swim Totals
7th Graders 15 45 60
8th Graders 50 45 95
Totals 65 40 105
