how many distinguishable ways are there to rearrange the letters in the word “symbolism”?

Answer: 12.3 cm

Step-by-step explanation:

          We are given the perimeter and all but one of the missing side lengths. The perimeter is equal to all of the side lengths added together. Using this information, we can create an equation to solve for the missing length, ?.

? = 65.9 cm - (9.2 cm + 4.7 cm + 4.7 cm + 2.2 cm + 9.2 cm + 2.2 cm + 12 cm + 4.7 cm + 4.7 cm)

? = 65.9 cm - 53.6 cm

? = 12.3 cm

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.

∠ADC and ∠ABC subtend the same arc AC, hence ∠ABC is double the measure of ∠ADC:

The solution to the system of equations is

x = 3

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

y = 2

Therefore, the solution to the system of equations is:

x = 3

y = 2

z = 2

Therefore, the minimum amount of rubber needed to manufacture a set of four basketballs is 1130.96 square inches.

To determine the minimum amount of rubber needed to manufacture a set of four basketballs, we need to calculate the total surface area of one basketball. The formula to calculate the surface area of a sphere is 4πr², where r is the radius of the sphere. The diameter of a standard basketball is 9.5 inches, so the radius is half of that, which is 4.75 inches.
Using the formula, we can calculate the surface area of one basketball as 4π(4.75)² = 282.74 square inches. To manufacture a set of four basketballs, we need to multiply the surface area of one basketball by four, which gives us 1130.96 square inches.

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.

It's worth noting that the solution assumes that the calorie content of the meals on both days is the same and only the calorie content from the cookies varies.

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%.

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:

Thus, the probability of being dealt a full house with an Ace of Hearts is 0.0457% (rounded to 4 decimal places).

To calculate the probability of being dealt a full house with an Ace of Hearts in a standard 52-card deck, we can use the following formula:

=(number of ways to get a full house with an Ace of Hearts) / (total number of 5-card poker hands)

The total number of 5-card poker hands is C(52,5) = 2,598,960.

To count the number of ways to get a full house with an Ace of Hearts, we need to consider the following:

We choose 2 of the remaining 3 Aces from the deck: C(3,2) = 3

We choose 2 of the 12 remaining ranks for the other 2 cards: C(12,2) = 66

For each rank, we need to choose 2 cards from the 4 of that rank: C(4,2) = 6

Therefore, the number of ways to get a full house with an Ace of Hearts is 3 x 66 x 6 = 1,188.

Thus, the probability of being dealt a full house with an Ace of Hearts is:

The measure of the angle m∠ACB subtended by the arc AB at the center is equal to 140°

The angle subtended by an arc of a circle at it's center is twice the angle it substends anywhere on the circles circumference. Also the arc measure and the angle it subtends at the center of the circle are directly proportional.

The arc AB completes the circumference of the circle, with the other arc ADB

So since;

arc AB = 360° - 220°

arc AB = 140°

To find the ratio of the volumes of two similar right cylinders, we need to know the ratio of their heights and radii. We can use the fact that the ratio of their surface areas is 36:121 to determine this. So, the ratio of the volumes of the two right cylinders is 216:1331.
Let the height and radius of the first cylinder be h1 and r1, respectively, and the height and radius of the second cylinder be h2 and r2, respectively. Then, we can write:
(2πr1h1)/(2πr2h2) = 36/121
Simplifying this equation, we get:
r1h1/r2h2 = 18/121
Since the cylinders are similar, we know that their ratios of heights and radii are equal. So, we can write:
r1/r2 = h1/h2 = x
Substituting this into our equation above, we get:
x^2 = 18/121
x = √(18/121) = 3/11
Therefore, the ratio of the volumes of the two cylinders is:
(r1^2h1)/(r2^2h2) = (r1/r2)^2(h1/h2) = (3/11)^2 = 9/121
In other words, the volume of the second cylinder is 121/9 times the volume of the first cylinder. Answer more than 100 words.
The ratio of the surface areas of two similar right cylinders is 36:121. To find the ratio of their volumes, we can use the fact that when two similar solids have a ratio of their surface areas (A1:A2), the ratio of their volumes (V1:V2) is the cube of the ratio of their corresponding linear dimensions (L1:L2).
First, let's find the ratio of the linear dimensions:
√(A1/A2) = √(36/121) = 6/11
Now, cube the ratio of the linear dimensions to find the ratio of their volumes:
(6/11)^3 = (6^3)/(11^3) = 216/1331
So, the ratio of the volumes of the two right cylinders is 216:1331.

a) Yes, this provide strong evidence that more than 15% of college students in America have at least one sibling

b) Type of error might you have committed is type 1 error.

We can use the sample proportion of students with at least one sibling (20/100 = 0.2) to calculate a test statistic, which measures how far the sample proportion is from the null hypothesis. In this case, we can use a one-sample proportion z-test to calculate the test statistic:

z = (p1 - p) / √(p * (1 - p) / n)

where p1 is the sample proportion, p is the null hypothesis proportion, and n is the sample size.

Using the values from your question, we get:

z = (0.2 - 0.15) / √(0.15 * 0.85 / 100) ≈ 1.18

We can use a standard normal distribution to find the p-value, which is the probability of getting a test statistic as extreme as the one we observed, assuming the null hypothesis is true. The p-value can be calculated as:

p-value = P(Z > z)

where Z is a standard normal random variable.

Using a calculator or a table of standard normal probabilities, we can find that the p-value is approximately 0.12.

To make a decision about whether to reject or fail to reject the null hypothesis, we compare the p-value to a significance level, which is a threshold that we set to determine how much evidence we need to reject the null hypothesis.

The most common significance level is 0.05, which means that we are willing to accept a 5% chance of rejecting the null hypothesis when it is actually true.

In this case, the p-value (0.12) is greater than the significance level (0.05), so we fail to reject the null hypothesis. This means that we do not have strong evidence to conclude that more than 15% of college students in America have at least one sibling based on this sample.

Now, let's talk about the type of error that we might have committed when testing the hypothesis. In hypothesis testing, there are two types of errors: type I error and type II error.

A type I error occurs when we reject a true null hypothesis, and a type II error occurs when we fail to reject a false null hypothesis.
