Answer:

000.3

Step-by-step explanation:

The probability of getting exactly 3 tails is 0.25 If a fair coin is tossed 4 times, what is the probability.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

We have a coin if it is tossed 4 times.

Then the probability of getting exactly 3 tails is:

[tex]=\rm 4 C_3(\frac{1}{2} )^3\times (1-\frac{1}{2} )^1[/tex]

[tex]=\rm 4\times \frac{1}{16}[/tex]

= 1/4

= 0.25

Thus, the probability of getting exactly 3 tails is 0.25 If a fair coin is tossed 4 times, what is the probability.

Answer:

7200

Step-by-step explanation:

450 x 2 = 900

900 x 8 =7200

(5a + 18) + (48 - a) + (8a - 30) = 180

5a + 18 + 48 - a + 8a - 30 = 180

5a - a + 8a + 18 + 48 - 30 = 180

12a + 36 = 180

12a = 180 - 36

12a = 144

a = 12

Answer:

The confidence interval for the population proportion p is between ( 0.165 and 0.335 )

Hence, Option a) 0.165 and 0.335 is the correct answer.

Step-by-step explanation:

Given the data in the question;

sample size n = 100

sample proportion p₀ = 0.25

q₀ = 1 - p₀ = 1 - 0.25 = 0.75

confidence interval = 95%

First we calculate our Standard Error

Standard Error = √( ( p₀ × q₀ ) / n )

we substitute

Standard Error = √( ( 0.25 × 0.75 ) / 100 )

Standard Error = √( 0.1875 / 100 )

Standard Error = √0.001875

Standard Error = 0.0433

Now, For 95% confidence interval; z = 1.96

so confidence interval for the population proportion p will be;

⇒ p₀ ± ( z × Standard Error )

we substitute

⇒ 0.25 ± ( 1.96 × 0.0433 )

⇒ 0.25 ± 0.084868

⇒ (  0.25 - 0.084868 ), (0.25 + 0.084868 )

⇒ (  0.25 - 0.084868 ), (0.25 + 0.084868 )

⇒ ( 0.165, 0.335 )

Therefore, The confidence interval for the population proportion p is between ( 0.165 and 0.335 )

Hence, Option a) 0.165 and 0.335 is the correct answer.

como el cono va con la del toda la izquierda de la de la mitad

Answer:

a) 1 / 12

b) 1 / 4

Step-by-step explanation:

The events are independent since they do not affect each other. The total probability of two independent events is the product of the probabilities of the two events.

a) When rolling a die, there are 6 outcomes, the numbers 1 - 6. There is only 1 outcome where you can get a 2. Therefore, the probability of rolling a two is 1/6.

When flipping a coin, there are two ways it can land: heads or tails. And there is one outcome with heads. The probability of getting head would be 1 / 2.

To find the the total, you multiply the probabilities of the two events: 1 / 6 * 1 / 2 = 1 / 12

b) As stated before, when rolling a die, there are 6 outcomes, the numbers 1 - 6. There are 3 outcomes where she can roll an even number: the numbers 2, 4, or 6. So, the probability of rolling an even number is 3 / 6 or 1 / 2.

When flipping a coin, there are two ways it can land: heads or tails. And there is one outcome with tails. The probability of getting tails would be 1 / 2.

Now, you multiply the two probabilities to get the total probability: 1 / 2 * 1 / 2 = 1 / 4

Answer:

The volume of the prism is of 1368 cubic m.

Step-by-step explanation:

Volume of a rectangular prism:

The volume of a rectangular prism is the multiplication of the lengths of its dimensions.

In this question:

Dimensions of 8m, 9m and 19m. So

8*9*19 = 1368.

Dimensions in meters, so volume in cubic meters.

The volume of the prism is of 1368 cubic m.

Answer:

500Hertz

Step-by-step explanation:

Using the formula for calculating frequency in terms of period expressed as;

f = 1/T

f is the frequency

T is the period

Given

T = 0.002seconds

Frequency f = 1/0.002

Frequency f  = 500Hertz

Hence the frequency in hertz for the sound wave is 500Hertz

Answer:

The height of the building is of 1026.52 feet.

Step-by-step explanation:

This situation is modeled by a right triangle, in which the length of the opposite side to the angle of 11º is the height of the building, while the length of the adjacent side is of 5281 feet.

Tangent:

In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.

In this question:

[tex]\tan{(11)} = \frac{x}{5281}[/tex]

[tex]x = 5281*\tan{(11)}[/tex]

Using a calculator, we have that the tangent of 11 degrees is: 0.1944. Thus:

[tex]x = 5281*\tan{(11)} = 5281*0.1944 = 1026.52[/tex]

The height of the building is of 1026.52 feet.
