Answer:
Step-by-step explanation:
Use the distance formula:
He should use the median because there is an outlier that affects the mean.
In this case, the outlier / 'extreme value' is E. We can see that most of the house prices are between $150,000 to $200,000, but E is much higher, therefore making it an outlier.
The answer is: " £120."

Answer:
n=18
Step-by-step explanation:
100=4(n+7)
100=4n+28
-28 -28
72=4n
n=18
In case this wasn't easy to understand, first you distribute the 4 to the n and 7, to get 28, after that the equation becomes 100=4n+28, then you subtract 28 from 100, and from itself to get the 4n by itself, you are left with 72=4n, after that you just divide 4n and 72 by 4 and get n=18
hope that helped :)
