Math Problem Statement
Solution
To complete the two-way table, we will fill in the missing values based on the provided data and totals. Here's what we have so far:
Year 9 | Year 11 | Total | |
---|---|---|---|
Pet | 16 | 6 | ? |
No Pet | 25 | ? | ? |
Total | 41 | ? | 70 |
-
Fill the Total for "Pet" row:
The total number of students who have pets is calculated by adding the number of Year 9 students with pets to the number of Year 11 students with pets.
So, the total for the "Pet" row is 22. -
Find the number of Year 11 students:
The total number of Year 11 students can be calculated by subtracting the number of Year 9 students from the total number of students.
So, the total number of Year 11 students is 29. -
Find the number of Year 11 students without pets:
Subtract the number of Year 11 students with pets from the total number of Year 11 students.
So, there are 23 Year 11 students without pets. -
Find the total number of students without pets:
Add the number of Year 9 students without pets and the number of Year 11 students without pets.
So, the total number of students without pets is 48.
Now the completed table looks like this:
Year 9 | Year 11 | Total | |
---|---|---|---|
Pet | 16 | 6 | 22 |
No Pet | 25 | 23 | 48 |
Total | 41 | 29 | 70 |
Would you like further explanation, or do you have any additional questions?
Here are 5 relative questions for further practice:
- How would you calculate the percentage of Year 9 students who have pets?
- What fraction of all students have pets?
- How many more Year 11 students do not have pets compared to those who do?
- If 5 more Year 9 students got pets, how would that change the table?
- What is the ratio of students without pets to those with pets?
Tip: When working with tables, double-check that both the row and column totals match the grand total for consistency.
