Answer:

Step-by-step explanation:

We can solve this problem using the binomial distribution. Let's define a "success" as selecting a passenger who is listening to music.

The probability of success is p = 1/3, since one-third of the passengers are listening to music.

The probability of failure is q = 1 - p = 2/3, since two-thirds of the passengers are not listening to music.

We want to find the probability of selecting exactly three passengers who are listening to music, which can be represented as P(X = 3), where X is the number of passengers selected who are listening to music.

Using the binomial probability formula, we have:

P(X = 3) = (5 choose 3) * (1/3)^3 * (2/3)^2

where (5 choose 3) = 5! / (3! * 2!) = 10 is the number of ways to choose 3 passengers out of 5.

Plugging in the values, we get:

P(X = 3) = 10 * (1/3)^3 * (2/3)^2

= 0.13169 (rounded to 5 decimal places)

Therefore, the probability that exactly three passengers are listening to music is approximately 0.13169.

Answer:

-3=v

Step-by-step explanation:

-12=9+7v

-9 from both sides

-21=7v

Divide both sides by 7

-3=v

Hope this helps:) Have a good day!

Answer:

v = - 3

Step-by-step explanation:

- 12 = 9 + 5v + 2v , that is

- 12 = 9 + 7v ( subtract 9 from both sides )

- 21 = 7v ( divide both sides by 7 )

- 3 = v

The latest time for pickup, found by converting the 150 minutes maximum time provided by the school, from minutes to hours is about 5:45 pm

Minutes can be converted into hours by dividing the number of minutes by 60, which is the number of minutes in an hour.

The time that school ends = 3:15 pm

The latest time for pick up after school care = 150 minutes after school ends

Therefore, the latest time for pick up after school care = 3:15 pm + 150 minutes

60 minutes = 1 hour

150 minutes = (1/60) × 150 = 2.5

The latest for pick up = 3:15 pm + 2.5 hours = 5:45 pm

Answer:

x^2 + 8x + 16

Step-by-step explanation:

Given length of square x + 4.

Area of square with side S is given by \(S^2\).

Therefore are of square with side x + 4 is given by \((x + 4)^2\)

Area of square = \((x + 4)^2\\=>(x + 4)*(x + 4)\\=> x(x + 4) + 4(x + 4)\\=> x^2 + 4x + 4x + 4*4\\=> x^2 + 8x + 16\)

Thus, x2 + 8x + 16 expression represents the area of a fabric square.

Step-by-step explanation:

To find the time for each event in cooking a pizza at a neighborhood pizza joint, where the cooking time is normally distributed with a mean of 12 minutes and a standard deviation of 2 minutes, we can calculate the probabilities associated with specific time intervals using the normal distribution.

First, let's consider the time it takes for a pizza to cook within a certain range. For example, to find the probability that a pizza cooks in less than 10 minutes, we can use the cumulative distribution function (CDF) of the normal distribution. By calculating P(X < 10) where X represents the cooking time, we can determine the probability. Similarly, we can calculate the probability for a pizza to cook within a specific range, such as between 10 and 15 minutes, by finding P(10 < X < 15).

To find the time for a specific event, such as the cooking time at which only 10% of the pizzas take longer, we can use the inverse CDF (also known as the quantile function or percent-point function). By calculating the quantile function for a probability of 0.10, we can determine the corresponding cooking time.

In summary, to find the time for each event in cooking a pizza at the neighborhood pizza joint, we can use the normal distribution with a mean of 12 minutes and a standard deviation of 2 minutes. By utilizing the CDF, we can calculate the probabilities associated with specific time intervals, and by utilizing the inverse CDF, we can find the cooking time for specific probabilities or percentiles.

While there is agreement on the use of focus groups for evaluating brand names, there are differences in the methods proposed for identifying symbolism associated with posting selfies and searching for ideas for new applications.

In comparing my initial post with my classmate's initial post, there are both areas of agreement and disagreement regarding the research methods suggested for different scenarios.

Agreement:

Both my initial post and my classmate's post agree on the use of focus groups for evaluating potential brand names for a new app. Focus groups allow for gathering opinions and insights from individuals in a controlled environment, as my classmate mentioned. I also referenced Babin (2019) to support this method.

Disagreement:

In terms of identifying the symbolism associated with posting selfies online, I suggested using detailed interviews, while my classmate proposed depth interviews.

While both methods aim to uncover deeper motivations and intentions, my classmate specifically highlighted the need for probing and asking a series of questions. Both approaches can provide valuable insights, but the emphasis on depth interviews suggests a more targeted and focused approach.

For searching for ideas for new smartphone or tablet applications, I suggested conducting detailed interviews with target customer groups, while my classmate proposed creating an attribute list.

While my suggestion focuses on gathering specific customer preferences and needs through direct interaction, my classmate's suggestion of attribute listing involves breaking down existing products and recombining their attributes to generate new ideas. These are two different approaches to idea generation, and the choice depends on the specific context and objectives of the research.

Answer:

200%

Step-by-step explanation:

if you substitute in numbers you'll find this as the answer.

as an example:

suppose the sides of the rectangle was 1 unit long.

area before change: 1 * 1 = 1

then, the length gets increase by 50% making it 1.5 ( 50% of 1 is 0.5, then you add it onto 1, 1 + 0.5 = 1.5 )

the width gets increased by 100% making it 2 ( 1 + 1 = 2 )

new area: 1.5 * 2 = 3

1 increased by 200% is 3, therefore the answer is 200%

Answer:

What is a mean?

A mean is the average of all the numbers in a data set.

How can I find mean?

to find mean you add up all the numbers in the data set; and divide them by the amount of numbers there are.

103+3+41+7=154

154÷4=38.5

The mean is 38.5

Answer:

81.59%

Explanation:

To find the percentage, we first need to standardize $7100. To standardize, we subtract the mean and then divide by the standard deviation. So, $7100 is equivalent to:

Now, the percentage of day care costs that are more than $7100 is equivalent to the probability that z is greater than -0.9, so:

P(x > $7100) = P(z > -0.9)

Finally, we can use the standard normal distribution table to get:

P(z > -0.9) = 0.8159

So, the answer is 81.59%

Answer:

The amount of time Jill trained this month is 125% of the amount of time she trained last month, which was 80 hours. To find the number of hours she trained this month, we can multiply 80 hours by 125%:

80 hours * 125% = 80 hours * 1.25 = 100 hours

So Jill trained for 100 hours this month.

Answer:

100hours

100 hours / 80 hours * 100% = 125%

Step-by-step explanation:

The amount of time Jill trained this month is 125% of the amount of time she trained last month, which was 80 hours. So, she trained for 125% of 80 hours = 100 hours.

To find this answer as a percentage, we can calculate what percentage of 80 hours 100 hours is:

100 hours / 80 hours * 100% = 125%

So Jill trained for 125% of the amount of time she trained last month.

Answer:

$538

Step-by-step explanation:

The minimum payment in the first month would be:

Minimum payment = 1.5% * $19,500 + 3% * $19,500 = $292.25

At the end of the first month, the balance would be:

Balance = $19,500 + $19,500 * 1.5% - $292.25 = $19,318.375

In the second month, the minimum payment would be:

Minimum payment = 1.5% * $19,318.375 + 3% * $19,318.375 = $291.26

At the end of the second month, the balance would be:

Balance = $19,318.375 + $19,318.375 * 1.5% - $291.27 = $19,138.89

In the third month, the minimum payment would be:

Minimum payment = 1.5% * $19,138.89 + 3% * $19,138.89 = $290.26

At the end of the third month, the balance would be:

Balance = $19,138.89 + $19,138.89 * 1.5% - $290.26 = $18,961.62

So, Ellen would have paid off $19,500 - $18,961.62 = $538.38. The answer rounded to the nearest cent is $538
