Step-by-step explanation:
If you put all of those points on a graph you get a slope of 4 and a perfectly straight line.
S^3=216yd^3 so then s=6 yd
Heads heads
Heads tails
Tails heads
Tails tails
There are four possibilities. There is only one where heads happens twice; therefore, the probability is 1/4, or 25%. I hope I helped! ^u^
For this case we have the following system of equations:
We multiply the first equation by -2:

We add the equations:

Adding we have:

We look for the value of "y":

So, the solution is
