A miner is drilling at a constant rate when her supervisor requests a status update. She looks at her drill’s depth gauge which says the elevation is 13 feet below ground level. 3 hours later, the drill’s elevation is 21 feet below ground level. A) At what rate is the drill’s elevation changing? Use a signed number, and include the unit of measurement in your answer.

B) How many more hours until she reaches her goal depth of 30 feet? Explain or show your reasoning.

C) How many hours before her team requested an update was the drill at the surface of the ground? Explain or show your reasoning.

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

6 and 24

step-by-step explanation:

6 x 4 = 24
