(please show your working out )Mr. Martin is making a swimming pool in his garden. He has three options, he can either make a triangular swimming pool or a circular swimming pool. In the remaining section outside the swimming pool, he will plant grass seeds to have nice green grass outside the swimming pool area. He will need to work out how much he would have to pay for the grass seed if grass seed comes in bags that cover 20 m2 and costs $10. please I really need this

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern

the answer is 24

step-by-step explanation:

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
