What is Pythagoras theorem give example?To determine the undiscovered side of a right-angled triangle, utilize the Pythagoras theorem. The hypotenuse (third side) of a right-angled triangle, for instance, can be determined using the formula c2 = a2 + b2, where 'c' stands for the hypotenuse and 'a' and 'b' are the two legs.According to the question:
We have been given that a community pool that is shaped like a regular pentagon needs a new cover for the winter months.To find the area of community pool we will use area of pentagon formula.\(Area of pentagon=\frac{1}{2} a * p$\) , where, a represents the apothem or perpendicular distance from the center of the pentagon and p represents perimeter of pentagon.Let us find the perimeter of our given pentagon by multiplying each side length by 5.
\(Perimeter of community pool $=5 \times 23.62\\Perimeter of community pool $=118.1$\)
Now let us find apothem of our pentagon by using Pythagoras theorem.
\(a^{2}=20.10^{2}-11.81^{2}\\$a^{2}=404.01-139.4761\\$a^{2}=264.5339\\$a=\sqrt{264.5339}\\$a=16.2645$\)
Upon substituting our given values in above formula we will get,
\(Area of community pool =\frac{1}{2} \times 16.2645 \times 118.1\\Area of community pool $=8.13224907 \times 118.1\\Area of community pool $=960.418615627971 \approx 960.42$\)
Therefore, the area of the pool that needs to be covered is 960.42 square feet.

A. 0.357
B. 0.313
C. 0.531
D. 0.343
E. 0.432
2. What is the probability that a person who is older than 35 years has a hemoglobin level between 9 and 11? (See first picture for table)
A. 0.257
B. 0.284
C. 0.312
D. 0.356
E. 0.548
3. A group of people were surveyed, and the data about their age and hemoglobin levels was recorded in a two-way table. Based on the data in the table, match each probability with its correct value. (See second picture for options)
4. Based on the data in the two-way table, the probability of being 25-35 years and having a hemoglobin level above 11 is (0.29, 0.34, 0.54). The probability of having a hemoglobin level above 11 is (0.25, 0.3, 0.36). Being 25-35 years and having a hemoglobin level above 11 (are, are not) dependent on each other. (See third picture for table)
very urgent, i'm trying to get all my school work done before the school year ends so i don't have to worry about it (and my parents will stop bugging me) -- thank you if you decide to help! these are some questions i was struggling on
1. the probability that a person who is above 35 years old has a hemoglobin level of 9 or above is 0.357.
2. the probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 is 0.264.
3. the probability is 0.08.
4. the probability of being 25-35 years and having a hemoglobin level above 11 is 0.0558.
1. To find the probability that a person who is above 35 years old has a hemoglobin level of 9 or above, we need to use the information given in the table. We can see that there are 170 people who are above 35 years old and have a hemoglobin level of 9 or above, and there are 478 people who are above 35 years old in total. Therefore, the probability is:
Probability = 170/478 = 0.355
So the answer is A. 0.357 (rounded to three decimal places).
2. To find the probability that a person who is older than 35 years has a hemoglobin level between 9 and 11, we need to use the information given in the table. We can see that there are 126 people who are older than 35 years and have a hemoglobin level between 9 and 11, and there are 478 people who are above 35 years old in total. Therefore, the probability is:
Probability = 126/478 = 0.264
So the answer is not one of the choices provided.
3. Probability of being 25-35 years old:
There are 151 people who are 25-35 years old out of a total of 900 people, so the probability of being 25-35 years old is 151/900 = 0.168.
Probability of having a hemoglobin level above 11:
There are 279 people who have a hemoglobin level above 11 out of a total of 900 people, so the probability of having a hemoglobin level above 11 is 279/900 = 0.31.
Probability of being 25-35 years old and having a hemoglobin level above 11:
There are 72 people who are 25-35 years old and have a hemoglobin level above 11 out of a total of 900 people, so the probability of being 25-35 years old and having a hemoglobin level above 11 is 72/900 = 0.08.
4. Based on the data in the two-way table, the probability of being 25-35 years and having a hemoglobin level above 11 is 0.29. The probability of having a hemoglobin level above 11 is 0.31. To determine whether being 25-35 years and having a hemoglobin level above 11 are dependent or independent, we need to compare the joint probability with the product of the marginal probabilities:
P(25-35 years and hemoglobin level above 11) = 0.29
P(25-35 years) = 0.18
P(hemoglobin level above 11) = 0.31
Product of the marginal probabilities = P(25-35 years) x P(hemoglobin level above 11) = 0.18 x 0.31 = 0.0558
Since the joint probability is not equal to the product of the marginal probabilities, we can conclude that being 25-35 years and having a hemoglobin level above 11 are dependent on each other.

Lindane (hexachlorocyclohexane) is an agricultural insecticide that can also be used in the treatment of head lice.
Draw the other chair conformation (B) of Lindane and inspect which of the following statements are correct.
a)B is more stable than A b)A is more stable than B c)A is not the correct representation of Lindane
d)The two chair conformation of Lindane are degenerate.
Here, Statement a) B is more stable than A is correct, while statements b), c), and d) are incorrect.
Lindane, also known as gamma-hexachlorocyclohexane, exists as a mixture of two stereoisomers. These stereoisomers have different chair conformations, often referred to as conformer A and conformer B. I will describe these conformations to help you analyze the statements provided.
Conformer A: In conformer A, one of the chlorine atoms is positioned in an axial (up) position, while the other five chlorine atoms are in equatorial (outward) positions. This arrangement is less stable due to steric hindrance caused by the axial chlorine atom, which experiences stronger interactions with neighboring groups.
Conformer B: In conformer B, the axial and equatorial positions of the chlorine atoms are interchanged compared to conformer A. The chlorine atom that was previously axial is now equatorial, and vice versa. This arrangement reduces the steric hindrance, leading to a more stable conformation.Now, let's analyze the provided statements:
a) B is more stable than A:
This statement is correct. Conformer B is indeed more stable than conformer A because it minimizes steric hindrance by placing the chlorine atoms in more favorable positions.b) A is more stable than B:
This statement is incorrect. As explained above, conformer B is more stable than conformer A.
c) A is not the correct representation of Lindane:
This statement is incorrect. Both conformers A and B are valid representations of Lindane, and the compound exists as a mixture of these conformations.
d) The two chair conformations of Lindane are degenerate:
This statement is incorrect. Degenerate conformations have the same energy level. In the case of Lindane, conformer B is more stable than conformer A, indicating that they have different energy levels and are not degenerate.

7/10 is the probability that a randomly selected student is a female or a liberal arts major.
Let us determine the number of female students:
15 + 18 + 17 = 50.
Determine the number of students majoring in liberal arts:
20 + 18 = 38.
Determine the number of students who are both female and liberal arts majors: 18.
Add the number of female students and the number of liberal arts majors, but subtract the overlap (students who are both female and liberal arts majors):
50 + 38 - 18
= 70.
Divide the result by the total number of students:
70 / 100

Solve each inequality. Check your solution. (x/3) + 5 ≥ 1/6
The inequality given by (x/3) + 5 ≥ 1/6 has the solution x ≥ -29/2 or [-29/2 , +∞).
Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.
To solve an inequality is to find the values of x such that when we substitute that number for x we have a true statement.
Given the inequality (x/3) + 5 ≥ 1/6, subtract 5 from both sides.
(x/3) + 5 - 5 ≥ 1/6 - 5
x/3 ≥ -29/6
Multiply both sides by 3.
3(x/3) ≥ 3(-29/6)
x ≥ -29/2
To check, let x = -29/2
x = -29/2 ≥ -29/2
Substitute this value to the inequality.
(x/3) + 5 ≥ 1/6
(-29/2)/3 + 5 ≥ 1/6
1/6 ≥ 1/6
let x = -14,
x = -14 ≥ -29/2

If a job interview says “tell me about yourself” what do u say
Answer:
I start to say from my name,age,family,qualifications and etc.
Answer:
In your response, do the following:
1. Mention past experiences and proven successes as they relate to the position.Begin by rereading the job description. Take note of the required skills that you have, and identify recent stories that demonstrate them . Ideally, you should draw primarily from recent professional experience; however, volunteer work can also support your narrative while demonstrating a commitment to your community.
2. Consider how your current job relates to the job you’re applying for.Is it a more senior role? If so, explain how you are taking on more responsibilities in your current position. If you are making a lateral transition to a role with different skills, describe how your current skills translate into the new position.
3. Focus on strengths and abilities that you can support with examples.When you start building the script of each example, focus on details and outcomes that you can quantify if possible. For example, stating that you “improved customer service” is less impactful than “increased customer service response rates each quarter by 10–15%.” If you don’t have the exact information, estimate a realistic value.
4. Highlight your personality to break the ice.Since the “Tell me about yourself” interview question is about getting to know you, it’s a good idea to share your personality with your interviewer—but not personal details. You may want to briefly mention hobbies that demonstrate intellectual development and/or community engagement (e.g., reading, music, sports league, volunteering) or those that showcase personal discipline and achievement (e.g., learning a new skill, training for a half marathon). Discussing personal interests is a good way to wrap up your response while maintaining a professional tone.
5. Format your response.For your response to be clear and concise, you’ll want to make sure you organize your answer following a format or formula. There are two common formulas you may consider:
Present, Past, FuturePast, Present, FutureBoth of these formulas work for your response, but you may choose one over the other based on the roles from your experience that are most relevant to the position you're interviewing for. For example, if your most recent role highlights many of the skills and qualifications that are required for the role you’re interviewing with, you may want to lead with the present. However, if you're making a career transition and your past experience is more closely related to the role than your current position, you may want to lead with your past.
To test his assistant, noted adventurer Dakota Davis states that the volume of the regular hexagonal ring at right is equal to the volume of the regular hexagonal hole in its center. The assistant must confirm or refute this, using dimensions shown in the figure. What should he say to Dakota?
Answer:
He should refute the affirmation, because the volumes are different.
Step-by-step explanation:
The area of a regular hexagon is given by the equation:
\(Area = 3\sqrt{3}side^2/2\)
And the volume is given by:
\(Volume = Area * height\)
The volume of the internal hexagon hole is given by:
\(V_{internal} = (3\sqrt{3}*4^2/2) * 2\)
\(V_{internal} = 83.1384\ cm^3\)
The volume of the ring is given by the volume of the bigger hexagon minus the volume of the internal hexagon:
\(V_{ring} = V_{external} - V_{internal}\)
\(V_{ring} = (3\sqrt{3}*6^2/2) * 2 - 83.1384\)
\(V_{ring} = 187.0615 - 83.1384\)
\(V_{ring} = 103.9231\ cm^3\)
The volumes are different, so the assistant should refute Dakota.
