Step-by-step explanation:

a probability is airways the ratio

number of desired cases / number of totally possible cases

so, we have 7 nickels and 6 dimes. together that means we have 7+6 = 13 coins in total in the pocket.

since we return the coin from the first pull, we have the exact same probabilities for the second pull.

the 2 pulls are to be considered one combined event, so we need to combine the individual probabilities for the overall event probability.

the probabilty to pull a nickel in a pull is

7/13

7 desired possible outcomes over 13 total possible outcomes.

the combination of the probabilities of both pulls is simply their product.

so, the probability to pull 2 nickels is

7/13 × 7/13 = 49/169 = 0.289940828...

Answer:

192

Step-by-step explanation:

To estimate the value of 64.127 × 3.413, we can simply round each decimal downwards:

We round downwards because to in order to estimate the product of 2 numbers, we need to make the equation as simple as possible. One way we can do this is round each number either upwards, or downwards.

To find out if we round upwards or downwards, we use the rule 5 or more rounds up.

Now we can solve.

Therefore, the estimated value of 64.127 × 3.413 is 192.

Answer:

a. The population distribution of the duration of your phone calls is likely to be bell shaped. This is because the mean, median, and mode are all equal to 2.4 minutes. This means that the data is evenly distributed around the mean.

b. The distribution of the 45 calls is likely to be bell shaped as well. This is because the sample size is large enough to be representative of the population. Additionally, the sample was randomly selected, so it is unlikely to be biased.

c. The sampling distribution of the sample mean is also likely to be bell shaped. This is because the central limit theorem states that the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution, as long as the sample size is large enough. In this case, the sample size is 45, which is large enough to satisfy the requirements of the central limit theorem.

It is important to note that the sampling distribution of the sample mean will only be exactly normal if the population distribution is normal. However, in most cases, the sampling distribution will be approximately normal, even if the population distribution is not.

The missing values from the ratio table are underlined:

Peppermints: 14, 2, 2/7.

Chocolates: 21, 21, 189.

To fill in the missing values in the ratio table, we need to find the common ratio between the given values.

For the Peppermints row:

Common ratio = (2nd value) / (1st value) = 2 / 14 = 1/7

So, the missing value can be found by multiplying the 2nd value (2) by the common ratio:

Missing value = (2nd value) * (common ratio) = 2 * (1/7) = 2/7

Therefore, the missing value in the Peppermints row is 2/7.

For the Chocolates row:

Common ratio = (3rd value) / (2nd value) = 189 / 21 = 9

The missing value in the Chocolates row can be found by dividing the 3rd value (189) by the common ratio:

Missing value = (3rd value) / (common ratio) = 189 / 9 = 21

Therefore, the missing value in the Chocolates row is 21.

The completed ratio table is as follows:

Peppermints - 14, 2, 2/7

Chocolates - 21, 21, 189

Increasing the number of scores in the samples for an independent-measures t-statistic has the effect of increasing the likelihood of rejecting the null hypothesis while having little or no effect on measures of effect size.

As the sample-size increases, the t-statistic becomes more robust and accurate, which leads to a more precise estimate of the population parameter. This increased precision reduces the variability in t-statistic, which makes it easier to detect small differences between the means of the independent groups.

With a larger sample size, the t-statistic's sampling distribution approaches a normal-distribution, allowing for more reliable statistical inference. This results in a narrower confidence interval and a smaller p-value, increasing the likelihood of rejecting the null hypothesis when there is a true difference between the groups.

Therefore, increasing number of scores in samples enhances power of independent-measures t-statistic.

Answer: 8575/2

Step-by-step explanation:

The Diagonal distance between point A and point B is approximately 8.2 units.

1. To find the diagonal distance between point A (2Y, 1X) and point B (9Y, 9X), we can use the distance formula:

distance = √((y2 - y1)^2 + (x2 - x1)^2)

distance = √((9 - 2)^2 + (9 - 1)^2)

distance = √(49 + 64)

distance = √113

distance ≈ 10.6

Therefore, the diagonal distance between point A and point B is approximately 10.6 units.

2. To find the diagonal distance between point A (4Y, -1X) and point B (-15Y, 3X), we can use the distance formula:

distance = √((y2 - y1)^2 + (x2 - x1)^2)

distance = √((-15 - 4)^2 + (3 - (-1))^2)

distance = √(361 + 16)

distance = √377

distance ≈ 19.4

Therefore, the diagonal distance between point A and point B is approximately 19.4 units.

3. To find the diagonal distance between point A (7Y, 1X) and point B (5Y, 9X), we can use the distance formula:

distance = √((y2 - y1)^2 + (x2 - x1)^2)

distance = √((5 - 7)^2 + (9 - 1)^2)

distance = √4 + 64

distance = √68

distance ≈ 8.2

Therefore, the diagonal distance between point A and point B is approximately 8.2 units.

If Andrea ate the same amount of calories both days, Each cookie has 100 calories.

To find out how many calories are in each cookie, we need to determine the total number of calories consumed and divide it by the total number of cookies.

On Friday, Andrea ate 4 cookies and 1700 calories with her meals, resulting in a total of 1700 + (4 * C) calories, where C represents the calories per cookie.

On Saturday, Andrea ate 5 cookies and 1650 calories with her meals, resulting in a total of 1650 + (5 * C) calories.

Since Andrea ate the same amount of calories both days, we can set up an equation:

1700 + (4 * C) = 1650 + (5 * C)

Simplifying the equation, we get:

50 = C

Therefore, each cookie has 50 calories.

If the saving rate is 1, it means that an individual or an economy saves their entire income and spends nothing. This implies that the consumption rate is 0, and all income is being saved.

In this scenario, the investment rate is equal to the saving rate, as there is no consumption spending. Therefore, the economy is investing all of its income in capital goods and not in consumption goods. This approach may result in high economic growth in the future due to the increased production capacity of the economy. However, in the short term, it may lead to a decrease in consumer demand and a decrease in output and employment in sectors producing consumer goods.

Therefore, the expected annual profit of Ruby Company is 2.703 billion dollars using probability.

Let X be the annual profit of the company. We know that X follows a normal distribution with variance equal to the cube of its mean, i.e., Var(X) = (E[X])^3.

To find the expected annual profit, we need to find the mean of X, denoted as E[X].

We are given that the probability of an annual loss is 5%. This means that the probability of making a profit is 1 - 0.05 = 0.95.

Let Z be a standard normal random variable, then we have:

P(X < 0) = P((X - E[X]) / sqrt(Var(X)) < (0 - E[X]) / sqrt(Var(X)))

= P(Z < -E[X] / (E[X])^(3/2))

Since P(X < 0) = 0.05, we have:

0.05 = P(Z < -E[X] / (E[X])^(3/2))

Using a standard normal table or calculator, we can find that P(Z < -1.645) = 0.05, where -1.645 is the 5th percentile of the standard normal distribution.

Thus, we have:

-E[X] / (E[X])^(3/2) = -1.645

this equation, we get:

E[X]^(1/2) = 1.645

Taking the square of both sides, we get:

The probability that more than 72% of the sampled UCF students will vote in the presidential election is approximately 0.0475 or 4.75%.

To calculate the probability that more than 72% of the sampled UCF students will vote in the presidential election, we need to use the normal distribution approximation since the sample size is large.

First, we find the mean (μ) and standard deviation (σ) of the sampling distribution using the given population proportion (p) of 0.70 and the sample size (n) of 1250:

μ = p = 0.70

σ = √(p(1-p)/n) = √(0.70 * 0.30 / 1250) ≈ 0.012

Next, we need to standardize the desired proportion of more than 72% (0.72) using the z-score formula:

z = (x - μ) / σ

z = (0.72 - 0.70) / 0.012 ≈ 1.67

Now, we can find the probability using the standard normal distribution table or calculator. The probability that more than 72% of the sampled students will vote in the presidential election is the area under the curve to the right of the z-score of 1.67.

Using the standard normal distribution table or calculator, we find that the probability is approximately 0.0475.

Therefore, the probability that more than 72% of the sampled UCF students will vote in the presidential election is approximately 0.0475 or 4.75%.

y = 2

z = 2

Here, we have,

To solve for x, y, and z, we can use the elimination method or substitution method. Here, we will use the elimination method.

First, we will eliminate y from the equations by multiplying the first equation by 3 and the second equation by 1, and then adding them:

(3) (2x – y + 3z = 10)

6x – 3y + 9z = 30

(1) (x + 3y – 2z = 5)

x + 3y – 2z = 5

Adding the two equations gives:

7x + 7z = 35

Simplifying, we get

x + z = 5 (Equation 1)

Next, we will eliminate y again by multiplying the second equation by 2 and the third equation by 3, and then adding them:

(2) (x + 3y – 2z = 5)

2x + 6y – 4z = 10

(3) (3x – 2y + 4z = 12)

9x – 6y + 12z = 36

Adding the two equations gives:

11x + 8z = 46

Substituting x + z = 5 from Equation 1 into the above equation, we get:

11(x + z) + 8z = 46

11x + 19z = 46

Solving for z, we get:

z = 2

Substituting z = 2 into x + z = 5 from Equation 1, we get:

x + 2 = 5

x = 3

Finally, substituting x = 3 and z = 2 into any of the original equations, we can solve for y:

2x – y + 3z = 10

2(3) – y + 3(2) = 10

6 – y + 6 = 10
