Answer:
0.1428 is the probability that both the pirate and the Captain hit each other's ships.
Step-by-step explanation:
We are given the following in the question:
Probability of captain hitting pirate's ship =
Probability of pirate hitting captain's ship =
If events are independent events, we can write:
We have to evaluate the probability that both the pirate and the Captain hit each other's ships.
0.1428 is the probability that both the pirate and the Captain hit each other's ships.
Answer: x= -8 or x = 1/2
Step-by-step explanation:
2x^2 + 15x = 8 Subtract 8 from both sides to let the whole equation equal 0
- 8 -8
2x^2 + 15x - 8 = 0 Now find two numbers that if you multiply them, their product will be -16 and their sum will be 15. An example is the numbers 16 and -1. 16 times -1 is -16 and 16 plus -1 is 15.
Rewrite the whole equation in this form,
2x^2 +16x - 1x - 8 = 0 Factor on the left side
2x ( x + 8) -1 (x + 8) = 0 Now factor out x + 8
(x + 8) (2x -1) = 0 Set each expression equal zero, because for the whole expression to equation to 0, either one of them or all of them have to equation zero.
x + 8 = 0 or 2x - 1 = 0
-8 -8 +1 +1
x = - 8 2x = 1
x = 1/2
