To construct the missing parts of the table, we need to determine the number of 7th graders who can swim, the number of 8th graders who can't swim, and the total number of 8th graders.
From the given data:
- Total number of 7th graders who cannot swim = 60
- Total number of 8th graders who can swim = 45
To find the missing information:
- Number of 7th graders who can swim = Total number of 7th graders - Number of 7th graders who cannot swim = 65 - 60 = 5
- Total number of 8th graders = Total number of 8th graders who can swim + Total number of 8th graders who cannot swim = 45 + 40 = 85
- Number of 8th graders who cannot swim = Total number of 8th graders - Number of 8th graders who can swim = 85 - 45 = 40
So, the completed two-way table is:
Can Swim Cannot Swim Totals
7th Graders 5 15 20
8th Graders 45 40 85
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?
