First we need to find the median of the data given. To do that, it should be in order:
12, 15, 18, 20, 23, 23, 28
So the median is 20
The only way to guarantee that the median doesn't change would be for the eight hour to have 20 visitors so the new data would be:
12, 15, 18, 20, 20, 23, 23, 28
Hope this helps!
Answer:

Step-by-step explanation:
Corresponding Angles are <em>congruent</em>, therefore you set both angle measures equal to each other:
![\displaystyle 135° = [3x + 15]° → 120 = 3x; 40 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20135%C2%B0%20%3D%20%5B3x%20%2B%2015%5D%C2%B0%20%E2%86%92%20120%20%3D%203x%3B%2040%20%3D%20x)

Answer:
4n + n + 6 + 4n + n + 6
10n + 12
he ought to have added the Ns
cc: He is supposed to add the coefficients of N
HCF is 6
That should be your answer
