Someone please help me I’ll give out brainliest please dont answer if you don’t know

D

Step-by-step explanation:

Numbers that cannot be expressed as fractions are considered irrational numbers

π cannot be expressed as fraction therefore it is an irrational number

√64 = 8 which can be expressed as a fraction therefore √64 is not an irrational number

is already expressed as a fraction therefore B is not the answer

.6 can be expressed is 6/10 therefore C is not the answer  

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
