Answer: Probability that both the pirate and the Captain hit each other's ships is 
Step-by-step explanation:
since we have given that
Probability that the captain hits the pirate ship is given by

Probability that the pirate hits the Captains's ship is given by

So, we have to find the "Probability that both the pirate and the Captain hit each other's ship" is given by

Hence, probability that both the pirate and the Captain hit each other's ships is 
Answer:
-2
Step-by-step explanation:
We can find the slope by using the slope formula
m = (y2-y1)/(x2-x1)
= (-5 - -7)/ ( -2 - -1)
= ( -5+7) / ( -2 +1)
= 2/-1
= -2
Fist u have to calculate how much it takes to reach the certain number for instance it takes 30 per gallon because 30 times 1 is 30. 30 times 2 is 60 and so on
