Saby used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. The results are shown in the tables b

P(Both) = 0.1792
Givens
The total number of roles = 100
Total number of heads = 56
Number of times rolled a four = 32 [check this for me].

Set up the probabilities.
P(H) = 56/100
P(4) = 32/100
P(H)*P(4) = P(Both)

Substitute and solve
P(Both) = 56/100 * 32/100 = 1792/10000
P(Both) = 112/625 because there are many cancellations. Or you could just express it as 0.1972

Hello,

$\dfrac{d^2( \int\limits^x_0 { \dfrac{2}{t^2+3t+1} } \, dt )}{dx^2} = \dfrac{d(\dfrac{2}{x^2+3x+1}) }{dx} \\

= \dfrac{-2(2x+3)}{(x^2+3x+1)^2}$

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

<u>DATA:</u>

<em>1. The weight of water for 1 cubic feet is 62.5</em>

<em>2. The weight of water for 'X' cubic feet is 325 </em>

<em>3. To find x, form an equation:</em>

Cubic feet : Weight of water

1 : 62.5

X : 325

<em>4. Cross multiply</em>

X x 62.5 = 1 x 325

62.5X = 325

<em>5. Make X the subject</em>

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

<em>6. Solve to find X</em>

X = 5.2 cubic feet

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