A parking lot has seventy-eight parking spaces numbered from 1 to 78. There are no cars in the parking lot when Jillian pulls in

polet [3.4K]

Answer:

49/78

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability that the number on the parking space where she parks is greater than or equal to 30 = numbers greater than or equal to 30 / total numbers

49 / 78

A triangle has a 60 degree angle, and the two adjacent sides are 12 and 12 times the square root of 3. Find the radius of a circ

Natasha_Volkova [10]

The radius of the circle is a line from the center of the circle to its circumference

The radius of the circle with the same vertex as a center is 10.16 units

<h3>How to determine the radius</h3>

From the question, we understand that:

The adjacent sides of the triangle are 12 and $12\sqrt 3$
The triangle has an angle of 60 degrees

Start by calculating the area of the triangle using:

$Area = 0.5ab\sin C$

So, we have:

$Area = 0.5 * 12 * 12\sqrt 3 *\sin (60)$

This gives

$Area = 0.5 * 12 * 12\sqrt 3 * \frac{\sqrt 3}{2}$

$Area = 108$

The arc divides the triangle into two equal regions.

So, the area of the arc is:

$Arc = 0.5 * Area = 0.5 * 108$

$Arc = 54$

Also, the area of the arc is:

$Arc = \frac{\theta}{360} * \pi r^2$

So, we have:

$Arc = \frac{60}{360} *3.14 * r^2$

Simplify

$Arc = 0.523 * r^2$

This gives

$0.523 * r^2 = 54$

Divide both sides by 0.523

$r^2 = 103.25$

Take the square roots of both sides

$r = 10.16$

Hence, the radius of the circle with the same vertex as a center is 10.16 units

Simplify (3 to the square of 6)to the square of 18

Zina [86]

Answer:

Evaluate.

Step-by-step explanation:

If you attempt to do the equation $3^{\sqrt{6} }^{^{\sqrt{18} } }$ , you will get a very long and complicated answer (which is 2.2233078e+21), so I am assuming that is not the question.

If you were to do $(3^{\sqrt{6} } ) (\sqrt{18} )$ , you would get a more rational answer of 62.566.

If you would comment on this post or be more specific on what exactly the question aims to ask, that would be a huge help. :)

An experiment consists of drawing 10 cards from an ordinary 52-card pack. (a) If the drawing is done with replacement, find the

irina [24]

Answer:

Probability = 0.0073

probability = 0.000007122

Step-by-step explanation:

given data

drawing = 10 cards

ordinary -card pack = 52 pack

solution

we know that here drawings done with replacement so that there is Probability that not 2 card of the same denomination

so

Probability = Probability of selecting a card × Probability of selecting a card not of the first denomination × Probability of drawing a card not from 2 denominations and continuous so on .......

so

Probability = 1 × $\frac{52-4}{52} \times \frac{52-8}{52}$ ... .... .... .... ... ...

Probability = 0.0073

and

when cards is drawn without replacement

probability = probability that exactly 9 of same suit and 10th of a different suit + Probability all 10 are of same suit

so

probability = $\frac{\frac{4}{1}\times \frac{13}{9}\times \frac{52-13}{1} + \frac{4}{1} \times \frac{13}{10} }{\frac{52}{10} }$

probability = 0.000007122
