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! :)

the second one is the answer <i think>
2(5x6)
2(30)
60
hope this helped :)
Answer:
2 + (−7) = −5, because −5 is 7 units to the left of 2
Step-by-step explanation:
Point S is on 2 on the number line shows Samuel's score after the first round of a quiz. In round 2, he lost 7 points
At first point S is 2 on the number line
So S is 2
in the second round he lost 7 points
for lost , subtract 7 from 2
so the point S is on -5 on round 2
2 + (−7) = −5, because −5 is 7 units to the left of 2
