place the steps required when using the inscribed polygon method for predicting aromaticity in the correct order, starting with the first step at the top of the list.
Answers
The steps required when using the inscribed polygon method for predicting aromaticity are as follows:
1. Draw the planar structure of the molecule: Start by drawing the planar structure of the molecule, making sure to include all the atoms and their connections. For example, let's consider the molecule benzene (C6H6) for this explanation.
2. Identify the π system: Look for the presence of a conjugated π system within the molecule. A conjugated π system consists of alternating single and double bonds or resonance structures. In benzene, the six carbon atoms form a conjugated π system.
3. Construct the inscribed polygon: Based on the positions of the π electrons, construct an inscribed polygon within the planar structure. This polygon connects the centers of the atoms that participate in the conjugated π system. In the case of benzene, the inscribed polygon would be a hexagon connecting the six carbon atoms.
4. Count the number of sides: Count the number of sides of the inscribed polygon. In the case of benzene, it is a hexagon, so there are six sides.
5. Determine the aromaticity: Based on Huckel's rule, a compound is aromatic if the number of π electrons in the molecule matches the number of sides of the inscribed polygon (4n + 2, where n is an integer). If the number of π electrons matches, the molecule is aromatic. In the case of benzene, it has 6 π electrons, which matches the number of sides of the inscribed polygon (6), making it aromatic.
In summary, the steps required when using the inscribed polygon method for predicting aromaticity include drawing the planar structure, identifying the π system, constructing the inscribed polygon, counting the number of sides, and determining the aromaticity based on Huckel's rule. By following these steps, you can predict the aromaticity of a molecule.

15.5% of an amount is 713.
What is the original amount?
Answers
Let the original amount be x
Then According to the question,
15.5 % of x is 713
15.5% * x = 713
(15.5 / 100 ) * x = 713 ( as 1 Percent =1/100)
x = 713 * 100/15.5
x = 4600
So, the original amount is 4600.
The original amount is calculated by setting up an equation using percentages, representing the original amount as X: 15.5 / 100 * X = 713. This equation is then solved to find X = (713 * 100) / 15.5, which results in X = 4600. Thus, the original amount is 4600.
The subject of the question is percentage calculation. In this situation, we can understand that 15.5 percent of an original amount equates to 713.
To find the original amount, we can set up an equation with the values provided. If we represent the original amount as X, then: 15.5 / 100 * X = 713.
To isolate X and hence find the original amount, we can solve this equation by dividing both sides by 15.5 and multiplying by 100: X = (713 * 100) / 15.5.
Calculating this gives us X = 4600. So, the original amount was 4600.

= 1/ [(1 + sinA)/cosA]
= cosA/(1+sinA)
Now check if this is identical to 1-sinA/cosA:
1-sinA/cosA = cosA/(1+sinA)
Cross multiply:
(1-sinA)(1+sinA) = cos^2A

suppose 76% of people like peanut butter, 82% like jelly, and 75% like both. given that a randomly sampled person likes peanut butter, what's the probability that he also likes jelly? (round your answer to four decimal places.)
Answers
The probability that a randomly sampled person who likes peanut butter also likes jelly is approximately 0.9868 (rounded to four decimal places
To solve this problem, we can use the concept of conditional probability. We want to find the probability that a randomly sampled person likes jelly given that they like peanut butter.
Let's define the events:
A: Person likes peanut butter.
B: Person likes jelly.
We are given the following probabilities:
P(A) = 0.76 (76% like peanut butter)
P(B) = 0.82 (82% like jelly)
P(A ∩ B) = 0.75 (75% like both)
We want to find P(B|A), which represents the probability of liking jelly given that the person likes peanut butter.
Using the formula for conditional probability:
P(B|A) = P(A ∩ B) / P(A)
Substituting the given values:
P(B|A) = 0.75 / 0.76 ≈ 0.9868

The Correlation Coefficienta) The scatterplot appears to show a positive association between the number of semesters needed to complete an academic program and the starting salary in the first year of a job. As the number of semesters increases, the starting salary generally increases as well. Therefore, the scatterplot supports the newspaper report.
b) The coefficient of determination, or R-squared value, represents the proportion of the variation in the dependent variable (starting salary) that is explained by the independent variable (number of semesters). A value of 0.335 means that 33.5% of the variation in starting salary is explained by the number of semesters. This value is relatively low, indicating that there are other factors that also contribute to starting salary.
c) The correlation coefficient is a value between -1 and 1 that measures the strength and direction of the linear association between two variables. A value of 1 indicates a perfect positive correlation, a value of -1 indicates a perfect negative correlation, and a value of 0 indicates no correlation. The correlation coefficient for this data is not provided in the problem, so it is not possible to determine it.

(c) at least two students? compare this with the exact probability. you may assume that the birthday of each of the other students is equally likely to be any one of the 365 days (no students born on leap years) and independent of each other
Answers
Using the Poisson Approximation the probability are:
a) 0.6321
b) 0.3679
c) 0.2642
The Poisson distribution is utilized to compute the likelihood of a particular amount of occurrences happening over a set period. The Poisson approximation will be used to answer the given question, and it is a form of a probability distribution that can be used to approximate the probability of particular events that occur infrequently, and it is suitable for both continuous and discrete variables.
a) The probability of having at least one student with the same birthday as Brad using the Poisson Approximation.
Let the number of other students with the same birthday as Brad be represented by x. Here, x is a discrete variable with a Poisson distribution that follows a Poisson distribution with an average of λ, which is equal to 1:
λ = average number of students having the same birthday as Brad = 1.
Using the Poisson distribution formula, the probability of having at least one student with the same birthday as Brad is given by:
P(X >= 1) = 1 - P(X = 0)
= 1 - e ^ (-λ)P(X = 0)
= (e^(-λ))(λ^0) / 0!
= e^(-λ)
= e^(-1)
= 0.3679
Therefore, the probability of having at least one student with the same birthday as Brad is:
P(X >= 1) = 1 - P(X = 0)
= 1 - 0.3679
= 0.6321
b) The probability of having exactly one student with the same birthday as Brad using Poisson Approximation
P(X = 1) = (e^(-λ))(λ^1) / 1!
= e^(-1)(1) / 1!
= e^(-1)
= 0.3679
Therefore, the probability of having exactly one student with the same birthday as Brad is:
P(X = 1)
= e^(-1)
= 0.3679
c) The probability of having at least two students with the same birthday as Brad using Poisson Approximation
P(X >= 2) = 1 - P(X < 2)
= 1 - [P(X = 0) + P(X = 1)]
= 1 - [e^(-λ)(λ^0) / 0! + e^(-λ)(λ^1) / 1!]
= 1 - [e^(-1) + e^(-1)(1) / 1!]
= 1 - [e^(-1) + e^(-1)]
= 1 - 2e^(-1)
= 0.2642
Compare the Poisson Approximation (a) Probability with the exact probability- At least one student with the same birthday as BradExact probability: 1 - (364/365)^180 = 0.4406
Poisson Approximation Probability: 0.6321
The exact probability is 0.4406, which is less than the Poisson approximation probability, which is 0.6321.
This result indicates that the Poisson approximation formula overestimates the likelihood of having at least one student with the same birthday as Brad.
(b) Exactly one student with the same birthday as BradExact probability: (364/365)^179(1/365) = 0.3775
Poisson Approximation Probability: 0.3679
The exact probability is 0.3775, which is quite similar to the Poisson approximation probability, which is 0.3679.
This result indicates that the Poisson approximation formula provides a reasonably precise estimate of the likelihood of having exactly one student with the same birthday as Brad.
(c) At least two students with the same birthday as BradExact probability: 1 - [1 + 364/365 + ... + (364!/347!)/365^34] = 0.1827
Poisson Approximation Probability: 0.2642
The exact probability is 0.1827, which is less than the Poisson approximation probability, which is 0.2642.
This result indicates that the Poisson approximation formula overestimates the likelihood of having at least two students with the same birthday as Brad.
