drek231 [11]

Answer:

0.225

Step-by-step explanation:

Total outcomes of choosing 5 out of 18 members = 18C5

Outcomes of choosing 2 out 11 favourers, 3 out of 7 members = 11C2 & 7C3

Probability = Favourable outcomes / Total outcomes

= ( 11C2 x 7C3 ) / 18C5

[ { 11 ! / 2! 9! } {7 ! / 3! 4! } ]

[ 18 ! / 5! 13! ]

( 55 x 35 ) / 8568

1925 / 8568

= 0.2246 ≈ 0.225

The weight of water is 62 1/2 per cubic feet. Water that weighs 325 lbs will fill how many cubic feet

yulyashka [42]

Water that weighs 325 lbs will fill 5.2 cubic feet.

Step-by-step explanation:

This is a simple question of cross multiplication

DATA:

1. The weight of water for 1 cubic feet is 62.5

2. The weight of water for 'X' cubic feet is 325

3. To find x, form an equation:

Cubic feet : Weight of water

1 : 62.5

X : 325

4. Cross multiply

X x 62.5 = 1 x 325

62.5X = 325

5. Make X the subject

X = $\frac{325}{62.5}$

6. Solve to find X

X = 5.2 cubic feet

Therefore, water that weighs 325 lbs will fill 5.2 cubic feet.
