daser333 [38]

Answer:

V=12\ ft^{3}

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

In this problem

P*V=k

step 1

Find the value of K

For P=24\ psi ,V=15\ ft^{3}

substitute

24*15=k

k=360

the equation is P*V=360

step 2

For P=30\ psi ,V=\ ft^{3}

substitute in the equation

(30)*V=360

V=360/30=12\ ft^{3}

erik [133]

Answer: Probability that both the pirate and the Captain hit each other's ships is \frac{1}{9}

Step-by-step explanation:

since we have given that

Probability that the captain hits the pirate ship is given by

\frac{4}{9}

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

\frac{1}{4}

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

P(\text{Captain hits})\times P(\text{ Pirates hit})\\\\=\frac{4}{9}\times \frac{1}{4}\\\\=\frac{1}{9}

Hence, probability that both the pirate and the Captain hit each other's ships is \frac{1}{9}
