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, you need to fill in the blanks with the numbers given in the question.
For the 7th graders:
- Can Swim: 15
- Cannot Swim: 60
For the 8th graders:
- Can Swim: 65 (Total Can Swim - Can Swim in 7th grade)
- Cannot Swim: 40 (Total Cannot Swim - Cannot Swim in 7th grade)
The completed two-way table would look like this:
Can Swim Cannot Swim Totals
7th Graders 15 60 75
8th Graders 65 40 105
Totals 80 100 180
Are you sure
Apologies for the confusion. Let me correct my response.
To construct the missing parts of the two-way table, we need to use the given information.
From the table:
- There are 65 students who can swim in total.
- There are 40 students who cannot swim in total.
To find the number of students who can swim and cannot swim in each grade, we subtract the corresponding numbers from the totals.
For the 7th graders:
- Can Swim: 65 - 45 (number of students who can swim in 8th grade) = 20
- Cannot Swim: 40 - 15 (number of students who cannot swim in 7th grade) = 25
For the 8th graders:
- Can Swim: 45
- Cannot Swim: 40
The completed two-way table would look like this:
Can Swim Cannot Swim Totals
7th Graders 20 25 45
8th Graders 45 40 85
Totals 65 65 130
To construct the missing parts of the two-way table, we need to use the information provided in the table:
1. The total number of 7th graders is given as 105. Since the total number of students who can swim is 65, we can subtract this from the total to find the number of 7th graders who cannot swim. Therefore, the missing value for "Cannot Swim" under "7th Graders" is 105 - 65 = 40.
2. The total number of 8th graders is not given in the table. However, we can find this value by subtracting the total number of 7th graders (105) from the overall total (105). So, the missing value for "Totals" under "8th Graders" is 105 - 105 = 0.
Using this information, we can complete the missing parts of the two-way table:
Can Swim Cannot Swim Totals
7th Graders 15 40 55
8th Graders 0 45 45
Totals 65 85 105
