A bag contains 7 red marbles, 5 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probabi

Korvikt [17]

Answer:

<h3>0.063</h3><h2>Step-by-step explanation:</h2>

<h3>probability is defined as the measure of chances of events happening or chances of occurrence.The probability that an event can happen is zero(0)</h3><h3>Probability can be calculated using the formular: number of required outcome all over number of total possible outcome.</h3>

Probability of 3 red = 7/16 x 6/15 x 5/14 = (7)(6)(5)/(16)(15)(14)=

6x5/16x15x2 = 5/16x5= 1/16 = (1/2)(.125) = 0.0625

Probability of 3 reds = 0.0625

round off to thousandths Pr(3R) = 0.063

Choose the correct answer. Speed of Plane A = 450 mph. Speed of Plane B = 350 mph. Both planes leave from Kansas City at the sam

8_murik_8 [283]

Keep in mind I've never actually attempted this kind of problem.

Calculate how far both planes are after 2.5 hours

450 × 2.5 = 1125

350 × 2.5 = 875

The legs of the triangle will be 1,125 miles & 875 miles.

1125² + 875² = 2,031,250

$\sqrt{2031250} = 1,425.21$

Plane A is 1,425 miles from Plane B.

Prove whether the following are identities 2tanh 1/2x / 1−tanh^2 1/2 x = sinh x

Tanzania [10]

Recall that

$\cosh^2(x) - \sinh^2(x) = 1$

Dividing both sides by cosh²(x) gives

$1 - \tanh^2(x) = \mathrm{sech}^2(x)$

Also, recall the identity

$\sinh(2x) = 2\sinh(x)\cosh(x)$

Then

$\dfrac{2\tanh\left(\frac x2\right)}{1 - \tanh^2\left(\frac x2\right)} = \dfrac{2\tanh\left(\frac x2\right)}{\mathrm{sech}^2\left(\frac x2\right)} \\\\ \dfrac{2\tanh\left(\frac x2\right)}{1 - \tanh^2\left(\frac x2\right)} = 2\tanh\left(\dfrac x2\right)\cosh^2\left(\dfrac x2\right) \\\\ \dfrac{2\tanh\left(\frac x2\right)}{1 - \tanh^2\left(\frac x2\right)} = 2\sinh\left(\dfrac x2\right)\cosh\left(\dfrac x2\right) \\\\\dfrac{2\tanh\left(\frac x2\right)}{1 - \tanh^2\left(\frac x2\right)} = \sinh(x)$
