Lily likes to collect records. last year she had 10 records in her collection. now she has 15 records. what is the percent increase of her collection?

50%

Step-by-step explanation: 15/10=1.5 THEN 1.5-1(ALWAYS - it by 1)=0.5 THEN 0.5x100=50% THERE YOU GO! Divide the 2 number minus it by 1 then TIMES IT BY 100 then whatever your answer is add a % and boom! Your welcome... FREE PALESTINE  

lo ; )

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
