x=20
and...

y=3×5
y=15
The first and last one are true!
Answer:
21.71
Step-by-step explanation:
1) you need to order then by the size
3, 13, 14, 16, 27.42, 37.97 ,64, 95
2) if there is an odd amount of numbers then the median would be the center term. but if it an even number then you add the two middle terms together and divide them by 2.
16+27.42= 43.42
43.42 divided by 2=21.71
