The cost of one tulip when the cost of ten tulip $7.80  is given by $0.78.

Cost of ten tulip is equal to $7.80.

To find the cost of 1 tulip, we can use unitary method .

Let us consider the cost of one tulip be '$x' .

If 10 tulips cost $7.80, then 1 tulip would cost 1/10th of $7.80.

This implies,

10x  = $7.80

Multiply both the side of the equation by ( 1/10 ) we get,

⇒ 1/10 × 10x  =  1/10 × $7.80

⇒ x = $0.78

Therefore, using the given cost of ten tulip the one tulip would cost $0.78.

The condition for the first dark fringe through a single slit of width w is when the path difference between the light waves at the edges of the slit equals a half wavelength= (λ/2).

This can be expressed mathematically as:
w * sin(θ) = (m + 1/2) * λ, where m = 0 for the first dark fringe, w is the slit width, θ is the angle of the dark fringe from the central maximum, and λ is the wavelength of light.
When light passes through a single slit, it diffracts and creates an interference pattern with alternating bright and dark fringes on a screen. The dark fringes occur when light waves from the edges of the slit interfere destructively, which means their path difference must be an odd multiple of half a wavelength (λ/2).
For the first dark fringe, we set m = 0 in the equation:
w * sin(θ) = (0 + 1/2) * λ
So, the condition for the first dark fringe is:
w * sin(θ) = λ/2

Hence, The condition for the first dark fringe through a single slit of width w is when the path difference between the light waves at the edges of the slit equals a half wavelength (λ/2). This can be represented by the equation w * sin(θ) = λ/2.

There are 122,305,536 ways Mrs. Candy can distribute the candy.

There are three types of candy, and each child receives three pieces, so a total of nine children will receive a total of 27 pieces of candy. Let's consider each type of candy separately.

First, let's consider the lollipops. Mrs. Candy can give each child up to three lollipops, and there are more than 30 lollipops available.

Using the stars and bars method, we can represent the distribution of lollipops as a sequence of 3 bars (|) and 30 stars (), where the bars represent the boundaries between each child's lollipops.

For example, the sequence " * | * * * | * * * * | * * *" represents a distribution where the first child receives 2 lollipops, the second child receives 3 lollipops, the third child receives 4 lollipops, and the fourth child receives 2 lollipops.

Using this method, we can count the number of possible distributions of lollipops as:

(30 + 3 - 1) choose (3 - 1) = 32 choose 2 = 496

Next, let's consider the chocolate bars. Mrs. Candy can give each child up to three chocolate bars, and there are more than 30 chocolate bars available.

Using the same method as before, we can represent the distribution of chocolate bars as a sequence of 3 bars and 30 stars. Counting the number of possible distributions of chocolate bars, we get:

(30 + 3 - 1) choose (3 - 1) = 32 choose 2 = 496

Finally, let's consider the caramels. Using the same method as before, we can represent the distribution of caramels as a sequence of 3 bars and 30 stars. Counting the number of possible distributions of caramels, we get:

(30 + 3 - 1) choose (3 - 1) = 32 choose 2 = 496

To find the total number of ways Mrs. Candy can distribute the candy, we need to multiply the number of ways of distributing each type of candy together, since the distributions are independent.

Thus, the total number of possible distributions of candy is:

496 * 496 * 496 = 122,305,536

Therefore, there are 122,305,536 ways Mrs. Candy can distribute the candy.

For analyzing the number of tickets sold for different concerts at a single venue in the past month, all three measures, mean, median, and mode, can provide useful information depending on the specific question we want to answer.

- The mean is the average number of tickets sold per concert, and it can help us understand the overall attendance at the venue. However, the mean can be skewed by a few high or low outliers, especially if there are some very popular or unpopular concerts that attract significantly more or fewer attendees than usual.

- The median is the middle value in the dataset, and it can help us identify the typical or typical range of ticket sales for concerts at the venue. The median is less affected by outliers than the mean, so it can be a more robust indicator of central tendency.

- The mode is the most frequent value in the dataset, and it can help us identify the most popular or least popular concerts at the venue. However, if there are several concerts with similar attendance numbers, there may not be a clear mode, or there may be multiple modes.

Therefore, it depends on the research question at hand, and all three measures should be considered together to gain a more complete understanding of the ticket sales for different concerts at a single venue in the past month.

Step-by-step explanation:

Using a unitary method, we have identified that the smaller pot has more water.

To compare the amount of water in the two pots, we need to find a common unit of measurement. In this case, both pots are measured in cups, so we can simply compare the number of cups in each pot. The chef filled the larger pot with 3.7 cups of water, and the smaller pot with 7.3 cups of water.

Now, we can use a unitary method to compare the two quantities. Let's assume that one cup is our unit of measurement. To find out how many cups of water are in the smaller pot, we can divide 7.3 by 1 cup. This gives us 7.3 cups of water. To find out how many cups of water are in the larger pot, we can divide 3.7 by 1 cup. This gives us 3.7 cups of water.

As we can see, the smaller pot has more water than the larger pot.

If the force and acceleration are in the same direction, the mass of the object would be 0.83 kg.

The mass of the object cannot be determined with the given information. Acceleration is related to force and mass through Newton's Second Law: F = ma. However, in this case, we are given the acceleration and force, but not the mass. To find the mass, we would need either the acceleration and the force, or the force and the mass.

However, if we assume that the force and acceleration are both in the same direction, we can use the formula F = ma to find the mass. Rearranging the formula, we get m = F/a.

Substituting the given values, we get:

m = 10 N / 12 m/s²

m = 0.83 kg

The number of voters that should be sampled for a confidence interval depends on the desired level of confidence and the margin of error.

A larger sample size generally leads to a smaller margin of error and a higher level of confidence in the accuracy of the results. However, the relationship between sample size and margin of error is not linear, meaning that doubling the sample size will not necessarily halve the margin of error.
To calculate the required sample size, a formula can be used that takes into account the margin of error, level of confidence, and population size.
the number of voters that should be sampled for a confidence interval depends on several factors and cannot be determined without more information.
To determine the required sample size, you can use the following formula:
n = (Z^2 * p * (1-p)) / E^2

Where:
- n is the sample size
- Z is the Z-score (usually 1.96 for a 95% confidence interval)
- p is the estimated proportion of the population (usually 0.5 for the worst-case scenario)
- E is the margin of error (in decimal form)

Hence, without the specific margin of error, we cannot provide the exact sample size needed.

The null hypothesis that the population mean is equal to 60 seconds cannot be rejected at a 0.01 significance level based on the available sample data, indicating that the students are reasonably good at estimating one minute.

To test the claim that the population mean is equal to 60 seconds, we can use a one-sample t-test. The null hypothesis is that the population mean is equal to 60 seconds, and the alternative hypothesis is that it is not equal to 60 seconds.

We can first calculate the sample mean and standard deviation:

sample mean (x') = (68 + 81 + 39 + 64 + 40 + 22 + 62 + 61 + 67 + 48 + 64 + 69 + 94 + 91) / 14 = 63.57

sample standard deviation (s) = 20.11

The test statistic can be calculated as:

t = (x' - μ) / (s / √n)

where μ is the hypothesized population mean (60 seconds), n is the sample size (14), and x' and s are the sample mean and standard deviation, respectively.

Substituting the values, we get:

t = (63.57 - 60) / (20.11 / √14) = 1.74

The degrees of freedom for the t-distribution is n - 1 = 13. Using a t-table or calculator, the p-value associated with a two-tailed test with 13 degrees of freedom and t = 1.74 is approximately 0.106.

Since the p-value is greater than the significance level of 0.01, we fail to reject the null hypothesis. Therefore, we do not have enough evidence to suggest that the students are not good at estimating one minute. We can conclude that it is plausible that the population mean is equal to 60 seconds, based on the available sample data.

Answer:

There are a total of 9 customers who have entered the drawing. The probability that the first winner lives in Gaston is 2/9, since there are 2 customers from Gaston out of 9 total customers.

Once the first winner is selected, there will be 8 customers remaining, out of which 2 live in Pike. Therefore, the probability that the second winner lives in Pike, given that the first winner lives in Gaston, is 2/8 or 1/4.

To find the probability that the first winner lives in Gaston and the second winner lives in Pike, we need to multiply the probabilities of the two events:

P(Gaston first and Pike second) = P(first winner from Gaston) * P(second winner from Pike, given that first winner is from Gaston)

P(Gaston first and Pike second) = (2/9) * (1/4)

P(Gaston first and Pike second) = 2/36

Therefore, the probability that the first winner lives in Gaston and the second winner lives in Pike is 2/36, which simplifies to 1/18.

- Let x be the width of the page in inches.

- Then the length of the page is 1.24x inches.

- The area of the page is x * 1.24x = 1.24x^2 square inches.

- We know that the area is about 621.96 square inches, so we can set up an equation:

- 1.24x^2 = 621.96

- To solve for x, we need to divide both sides by 1.24 and then take the square root:

- x = sqrt(621.96 / 1.24)

- x = sqrt(501.58)

- x = 22.4 (rounded to one decimal place)

- Therefore, the width of the page is about **22.4 inches**.

- The length of the page is 1.24 * 22.4 = 27.8 (rounded to one decimal place)

- Therefore, the length of the page is about **27.8 inches**.

The expected value of W is Php 4.96. This means that on average, a person who buys a 20-peso raffle ticket from a total of 1000 tickets has a chance to gain Php 4.96 from the raffle.

To find the expected value of W, we need to calculate the probability of each possible outcome and multiply it by its corresponding value.

The cost of a ticket is Php 20, and there are 1000 tickets sold, so the total revenue is 1000 x 20 = Php 20,000.

The probability of winning the raffle is 1/1000, and the prize money is Php 5000. So, the value of W in this case is 5000 - 20 = Php 4980.

The probability of losing the raffle is 999/1000, and the value of W in this case is -20.

So, the expected value of W can be calculated as follows

E(W) = (1/1000) x 4980 + (999/1000) x (-20)

E(W) = 4.98 - 0.02

E(W) = 4.96
