Louis must ride a mechanical lift to place 20 boxes on a high store shelf.
. louis weighs 140 pounds.
. there are x boxes that weigh 10 kilograms each and 20-x boxes that weigh 30 kilograms each.
. a kilogram is 2.2 pounds.

which expression shows the total weight, in pounds, that will be on the lift?

a.) 1,320 - 44x
b.) 1,460 - 44x
c.) 272 - 9.1x
d.) 412 - 9.1x

Step-by-step explanation:

so we have Louis who weighs 140 lbs

then we have x boxes that weigh 10 kgor (2.2 * 10) = 22 lbs

and we have (20 - x) boxes that weigh 30 kg or (2.2 * 30) = 66 lbs

140 + 22x + 66(20 - x) =

140 + 22x + 1320 - 66x =

1460 - 44x <

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
