The question illustrates binomial probability and the formula is:

So, we have:




Answer:
(22, - 24)
Step-by-step explanation:
Multiply the first equation by -5 to make the y's so you can add the up to zero.
-5(2x + y = 20)
-10x - 5y = -100 Add the second equation thn solve for x
<u> 6x + 5y = 12 </u>
-4x = -88
x = 22
Plug 22 in for x in either equation
2x + y = 20
2 (22) + y = 20
44 + y = 20
y = -24
Mr. Mole's burrow was at an altitude of 6 meters below the ground.
Step-by-step explanation:
Step 1:
We need to determine the distance that Mr. Mole covers in a single minute.
To do that we divide the difference in values of altitude by the difference in the time periods.
For the first case, Mr. Mole had traveled -18 meters in 5 minutes.
We also have, he traveled -25.2 meters in 8 minutes.
Step 2:
The distance he covered in 1 minute 

So with every minute, Mr. Mole digs down an additional 2.4 meters below the surface.
To determine where Mr. Mole's burrow is we subtract the distance traveled in 5 minutes from -18.
The altitude of Mr. Mole's burrow 
So Mr. Mole's burrow was at an altitude of 6 meters below the ground i.e. -6 meters.
