Answer:
Step-by-step explanation:
x = 6
The two angles are supplementary angles which means they need to equal 180 degrees when added together.
4x + x = 180
5x = 180
Divide both sides by 5:
x = 180/5
x = 36
If in 2000 there were 430 folksk, 2010 is 10 years later, thus t = 10
Answer:
4 students
Step-by-step explanation:
Although I am not sure if I am completely correct. I’ll try my best.
<u>We know:</u>
The numbers 0-12 on the frequency table is the number of windows.
The numbers on the bottom is the amount of students.
-
<u>What we can see:</u>
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.
-
<u>Calculations:</u>
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.
