The box plot represents a data set . What is the range of the middle 50% of the data?
2 answers:
Answer: 3
Step-by-step explanation:
We know that the interquartile range is known as the range of the middle 50% of the data.
- Interquartile range is the difference between the third quartile and first quartile.
From the given box plot , the first quartile ( where box starts )
The third quartile ( where box ends )
Then, the interquartile range =
Thus , the range of the middle 50% of the data =3

[ Explanation ]
4(y + 6) - 2(y - 2)
[Expand] 4(y + 6): 4y + 24
4y + 24 - 2(y - 2)
[Expand] -2(y - 2): -2y + 4
4y + 24 - 2y + 4
[Simplify] 4y + 24 - 2y + 4: 2y + 28
= 2y + 28
Area of the rectangle: 112
Step-by-step explanation:
Picture is missing: find it in attachment.
The area of a triangle is given by
where
b is the length of the base
h is the height
For triangle ABE, we know that
A = 40 (area)
h = 8 (height)
So we can find the length of the base AE:
Now we observe that the base of the rectangle, AD, is the sum of AE and DE, therefore:
We also know the height of the rectangle AB is 8, and that the area of a rectangle is
where b is the base and h the height. Therefore, the area of this rectangle is
