Answer:
4
Step-by-step explanation:
- If you take the lowest half of the data (from the lower extreme to the median) and find the median of these numbers, that is called the lower quartile or quartile 1.
- If you take the upper half of the data (from the upper extreme to the median) and find the median of these numbers, that is called the upper quartile or quartile 3.
- The interquartile range is the difference between quartile 1 and quartile 3.
- 4, 5, 6, 8, 9, 10, 11, 13
- Median=8.5
- Q1=6.5
- Q3=10.5
- 10.5-6.5=4

Answer:
The number in the green box should be 3.
Step-by-step explanation:

We know that sum of two sides in any triangle must be greater than the measure of third (longest) side otherwise triangle will not be formed.
According to picture longest side is 18
So this triangle must follow inequality
9+x>18
or 9-9+x>18-9
or x>9
that means value of x must be more than 9.
choices a, c, d are greater than 9 except choice b
Hence choice B-9 is the final answer.
