Answer:
4 students
Step-by-step explanation:
Although I am not sure if I am completely correct. I’ll try my best.
We know:
The numbers 0-12 on the frequency table is the number of windows.
The numbers on the bottom is the amount of students.
-
What we can see:
As we can see..
- the 0-4 section in the table shows that only 0-4 students have 9 windows.
- The 5-9 sections shows that only 5-9 students have 10 windows.
- The 10-14 sections shows that 10-14 students have 0 windows.
- The 15-19 sections shows that 15-19 students have 4 windows.
- The 20-24 sections shows that 20-24 students have 2 windows.
-
Calculations:
Since the number of students that have the amount of windows less than 10 is 4 (0-4 section) and 0 (10-14 section)
Add.
4+0
= 4
Therefore, 4 students have less than 10 windows.
