Answer:

The probability is 1/8 or 0.125

Step-by-step explanation:

In this question, we are concerned with calculating the probability that when a coin is flipped there would be a show of heads three times.

In flipping of a coin, there are only two possible results with equal probability. The probability of both events i.e P(H) and P(T) is equal and that is 1/2

Thus the probability of getting heads three times in a row will be P(HHH) meaning P(H) and another P(H) and another P(H)

When we have and in a probability question, that means we are to multiply the probabilities together.

Hence, P(HHH) = 1/2 * 1/2 * 1/2 = 1/8

Answer:

surface area = 28 yard²

Step-by-step explanation:

given data

1 unit length of cube = 1 yd

solution

As given image shown that rectangular solid has length 5 units, width 2 units, and height 2 units.

so we get here surface area that is we get by area of each of its faces

we can see three face are

A front = L × W  = 2 × 2 = 4

A side = L × W  = 5 × 2 = 10

A top = L × W = 5 × 2 = 10

so here

surface area = ( front + back ) + ( left side + right side ) + ( top + bottom )   ................1

surface area = ( 2 × front ) + ( 2 × left side ) + ( 2 × top )

surface area = ( 2 × 4 ) + ( 2 × 10 ) + ( 2 × 10 )

surface area = 8 + 20 + 20

Answer: Mara has a lot of yellow paint

Step-by-step explanation:

Mara has less green paint because 7 cups is the same as 56 fluid ounces and 56 is less than 64 (yellow paint)

Mara has 56 fluid ounces of green paint and 64 fluid ounces of yellow paint. Therefore, Mara has more yellow paint. The calculations involve converting units of measure for an accurate comparison.

To answer your question accurately, it would be necessary to convert the measurements to the same unit. Given that 1 cup is approximately 8 fluid ounces, Mara's 7 cups of green paint convert to 56 fluid ounces (7 cups * 8 ounces/cup).

Comparing this to the 64 fluid ounces of yellow paint, we find that Mara has more yellow paint.

The comparison was made by first converting the quantity of green paint from cups to fluid ounces for a direct, accurate comparison between the two quantities of paint. This kind of problem is a great example of why understanding units of measure is important in mathematics and in everyday life.

Answer:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

And we can find the nnumber of deviations from the mean for each limit given:

[tex] z_1 = \frac{17-32}{5} = -3[/tex]

[tex] z_2= \frac{47-32}{5} = 3[/tex]

So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values

Step-by-step explanation:

Let X the random variable that represent the amount of time it takes him to arrive, and for this case we know the distribution for X is given by:

[tex]X \sim N(32,5)[/tex]  

Where [tex]\mu=32[/tex] and [tex]\sigma=5[/tex]

We want to find this probability:

[tex]P(17<X<41)[/tex]

And we can use the z score formula given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

And we can find the nnumber of deviations from the mean for each limit given:

[tex] z_1 = \frac{17-32}{5} = -3[/tex]

[tex] z_2= \frac{47-32}{5} = 3[/tex]

So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values

Answer:

[tex]P(-0.28 <Z< 0.64) = P(Z<0.64) -P(Z<-0.28)[/tex]

[tex]P(Z<0.64) =0.739[/tex]

[tex]P(Z<-0.28) =0.390[/tex]

And with the difference we got: 0.739-0.390 = 0.349

And if we convert the probability to % we got 0.349*100 = 34.9%. And the best answer would be:

C. 34.9%

Step-by-step explanation:

For this case we want this probability:

[tex] P(-0.28 <Z< 0.64)[/tex]

And we can find this probability using the normal standard distribution and with the following difference:

[tex]P(-0.28 <Z< 0.64) = P(Z<0.64) -P(Z<-0.28)[/tex]

If we find the individual probabilities we got:

[tex]P(Z<0.64) =0.739[/tex]

[tex]P(Z<-0.28) =0.390[/tex]

And with the difference we got: 0.739-0.390 = 0.349

And if we convert the probability to % we got 0.349*100 = 34.9%. And the best answer would be:

C. 34.9%

The probability of a value falling between z-scores of -0.28 and 0.64 in a normal distribution is found by taking the cumulative area under the standard normal curve for each z-score and calculating their difference, which results in approximately 34.9% after rounding. Thus, the correct answer to the student's question is option C) 34.9%.

The question addresses the calculation of probabilities for specific ranges of z-scores in a normal distribution. To find the probability that a data value is between a z-score of -0.28 and a z-score of 0.64, we need to look at the standard normal distribution table or use a statistical software that provides the cumulative area up to these z-scores.

The probability of a value being less than z = 0.64 is P(Z < 0.64). According to the z-table, this probability is approximately 0.7389. Similarly, the probability of a value being greater than z = -0.28 (which is equivalent to less than due to symmetry) can be found as 1 - P(Z < -0.28), which, when referred to a z-table, gives a value of about 0.6103. Therefore, the total probability of a value being between z = -0.28 and z = 0.64 is the difference between these two probabilities, 0.7389 - (1 - 0.6103) = 0.3492 or 34.92%.

However, this value needs to be rounded to the nearest tenth of a percent, which yields 34.9%. So the correct answer is C. 34.9%.

Step-by-step explanation:

The problem involves calculating the speed of the current in a river using the given data: the speed of a boat in still water, the distance traveled downstream and upstream, and the total time taken. An application of the concept of relative speed helps solve the problem by setting up an equation reflecting the speeds during the downstream and upstream runs, then solving for the speed of the current.

The problem demonstrates an application of relative speed in the context of a boat moving in a stream. Let's denote the speed of the boat by 'b', the speed of the stream by 's', the time taken to move downstream by 't1', and the time taken to move upstream by 't2'. The speed of the boat in still water is given as 24 mph.

When moving downstream, the boat and the stream are going in the same direction, so their speeds add up: the actual speed will be b+s (24 mph + s). On the other hand, when moving upstream, the boat is going against the stream, so the actual speed is b-s (24 mph - s).

The total time taken to go 15 miles downstream and return is 80 minutes or 4/3 hours. Therefore, using the formula for time (time = distance/speed), we can set up the following equation: 15/(24+s) + 15/(24-s) = 4/3

Solving this equation will give us the value of 's', which represents the speed of the stream.

https://brainly.com/question/14362959

#SPJ12

The speed of the stream is 6mph.

To find the speed of the stream, we can use the concept of relative speed.

When the boat is going downstream (with the current), the effective speed is increased by the speed of the stream. So, the effective speed downstream is v + s

When the boat is going upstream (against the current), the effective speed is decreased by the speed of the stream. So, the effective speed upstream is V- s

1. Time taken downstream

[tex]\[ t_d = \frac{\text{Distance}}{\text{Speed}} = \frac{15}{v + s} \][/tex]

2. Time taken upstream

[tex]\[ t_u = \frac{\text{Distance}}{\text{Speed}} = \frac{15}{v - s} \][/tex]

3. Total time for the round trip

  The total time taken for the round trip is the sum of the time taken downstream and upstream.

[tex]\[ \frac{15}{v + s} + \frac{15}{v - s} = \frac{80}{60} \] (converted minutes to hours)[/tex]

Now, let's substitute v = 24 into the equations and solve for \( s \), the speed of the stream.

Once we have s  we can find the speed of the stream.

[tex]\[ \frac{15}{24 + s} + \frac{15}{24 - s} = \frac{4}{3} \][/tex]

Multiplying both sides of the equation by ( (24 + s)(24 - s) to clear the denominators:

[tex]\[ 15(24 - s) + 15(24 + s) = \frac{4}{3}(24 + s)(24 - s) \][/tex]

Taking the square root of both sides:

s= 6

Therefore, the speed of the stream is 6 mph.

Step-by-step explanation:

The area of a kite is the product of the diagonals divided by 2.

If the diagonals have lengths a and b, then area = ab/2

area = ab/2

a = horizontal diagonal = 2 m + 6 m = 8 m

b = vertical diagonal = 3 m + 3 m = 6 m

area = (8 m)(6 m)/2 = (48 m^2)/2 = 24 m^2

[tex]\sqrt{ab} =\sqrt{a}*\sqrt{b}[/tex]

Therefore:

[tex]\sqrt{128x^8y^3z^9}=\sqrt{128}*\sqrt{x^8}*\sqrt{y^3}*\sqrt{z^9}[/tex]

[tex]=\sqrt{64*2}*\sqrt{x^{4*2}}*\sqrt{y^{2+1}}*\sqrt{z^{8+1}}\\=8\sqrt{2}*\sqrt{x^{4*2}}*\sqrt{y^2*y}*\sqrt{z^{8}*z}}[/tex]

[tex]=8\sqrt{2}*x^4*y \sqrt{y}*z^4\sqrt{z}\\=8*x^4*z^4*\sqrt{2}*\sqrt{y}*\sqrt{z}\\=8x^4z^4\sqrt{2yz}[/tex]
