Sara drove 72 miles on 4 gallons of gas.

Sara drove 18 miles per gallon of gas.

72 miles ÷ 4 gallons of gas = 18 miles per gallon of gas

I think the answer is 18 because 72 divided by 4 is 18. I don't know if it is mph or if its miles per gallon. I don't know, it's one of those two so yah...

Hope this helps. c;

we don't have enough info to solve this

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
