Alexandra bought 4 spools of thread. Each spool held 375 meters of thread. How
many kilometers of thread did Alexandra
buy in all?

1.5km of thread

Step-by-step explanation:

1 spool = 375 m

4 spools = 375 x 4 = 1500

1500 m = 1.5km

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
