Answer:
C) 3
Step-by-step explanation:
This is just a differences of squares:
![(a+b)(a-b)=(a^2-b^2)\\\\(\sqrt{5}+\sqrt{2})(\sqrt{5}-\sqrt{2})=(\sqrt{5}^2-\sqrt{2}^2)=5-2=3](https://tex.z-dn.net/?f=%28a%2Bb%29%28a-b%29%3D%28a%5E2-b%5E2%29%5C%5C%5C%5C%28%5Csqrt%7B5%7D%2B%5Csqrt%7B2%7D%29%28%5Csqrt%7B5%7D-%5Csqrt%7B2%7D%29%3D%28%5Csqrt%7B5%7D%5E2-%5Csqrt%7B2%7D%5E2%29%3D5-2%3D3)
Hi!
First, find the median of the original data set.
Arrange the numbers in order,
2, 2, 4, 6, 7, 8, 18, 20, 24
Then find the middle number.
2, 2, 4, 6, 7, 8, 18, 20, 24
Now add the number 10.
2, 2, 4, 6, 7, 8, 10, 18, 20, 24
Find the new middle number.
2, 2, 4, 6, 7, 8, 10, 18, 20, 24
7.5
The first median was 7, the new one is 7.5.
The median increases by 0.5.
Hope this helps! :)
