The expression P(4, 3) is equal to:<br> -3!<br> -4!<br> - 1
nexus9112 [7]

Answer:

P(4,3) = 4!

Step-by-step explanation:

Given

P(4,3)

Required

Solve

Using permutation formula;

P(n,r) = \frac{n!}{(n-r)!}

This implies that

P(4,3) = \frac{4!}{(4-3)!}

P(4,3) = \frac{4!}{(1)!}

P(4,3) = \frac{4!}{1!}

P(4,3) = \frac{4!}{1}

P(4,3) = 4!

Keisha pumped 6 gallons of water into her pool each minute for 48 minutes what was the total change in the amount of water in th
Eduardwww [97]

The total change in the amount of water in the pool is 288 gallons.

<h3>What is Volume?</h3>

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

Here, Rate of water pumped into her pool = 6 gallons / minute.

          Total Duration = 48 minutes

Total amount of water = Rate X Time

                                     = 6 X 48

                                     = 288 gallons

Thus, the total change in the amount of water in the pool is 288 gallons.
