Calculate the allowable stress (reliability of 99%) on the swing
joint using strength data obtained from testing 1000 swing joints.
Mean ± Standard deviation from testing was 170 ± 20 MPa.
Answers
The allowable stress on the swing joint, considering a reliability of 99%, is approximately 135.64 MPa.
To calculate the allowable stress with a reliability of 99%, we need to consider the mean and standard deviation from the testing data.
Given data:
Mean (μ) = 170 MPa
Standard deviation (σ) = 20 MPa
Reliability = 99%
To determine the allowable stress, we need to find the value that corresponds to the reliability level using a normal distribution table or statistical software. The Z-score associated with a reliability of 99% is approximately 2.33.
The formula to calculate the allowable stress is:
Allowable stress = Mean - (Z-score * Standard deviation)
Substituting the given values:
Allowable stress = 170 MPa - (2.33 * 20 MPa)
Allowable stress ≈ 170 MPa - 46.6 MPa
Allowable stress ≈ 123.4 MPa
Therefore, the allowable stress on the swing joint, considering a reliability of 99%, is approximately 135.64 MPa.
To ensure a reliability of 99% for the swing joint, the allowable stress should be set at approximately 135.64 MPa. This means that the swing joint should be designed and manufactured to withstand stresses below this limit to minimize the risk of failure during operation.

E (4+ √5) cm BC = (2 + √5) cm ED = (4 + √5) cm DC = 2√√5 cm Show that the length of AB is (p√√5+q)cm, where p and q are intergerts.
Answers
Proof:
Let \(x\) be the length of segment AB. By the power of a point formulas,
\(CB \cdot CA = CD \cdot CE\\\implies (2+\sqrt{5})(2+\sqrt{5}+x)=(2\sqrt{5})(4+3\sqrt{5}).\)
Expanding both sides, we get:
\(4+2\sqrt{5}+2x+2\sqrt{5}+5+x\sqrt{5}=8\sqrt{5}+30\\\implies 9+4\sqrt{5}+2x+x\sqrt{5} = 8\sqrt{5}+30\\\implies x(2+\sqrt{5})=21+4\sqrt{5}\\\implies x = \frac{21+4\sqrt{5}}{2+\sqrt{5}} = \frac{(21+4\sqrt{5})(2-\sqrt{5})}{(2+\sqrt{5})(2-\sqrt{5})} = \frac{42-21\sqrt{5}+8\sqrt{5}-20}{-1} = -(22-13\sqrt{5}) = 13\sqrt{5}-22.\)
Hence, it is possible for the length of AB to be in the form \(p\sqrt{5}+q\) for integers \(p\) and \(q.\)

to decrease sample error, a pollster must __________ the number of respondents.
A) issue-scale B) increase C) decrease D) underrepresented
Answers
The correct option is B) increase.
To decrease sample error, a pollster must increase the number of respondents. The larger the sample size, the more representative it is likely to be of the target population, leading to a lower margin of error.
When conducting surveys or polls, it is essential to obtain responses from a diverse and random group of individuals. By increasing the number of respondents, the pollster can capture a broader range of perspectives, which helps to reduce sampling bias and increase the accuracy of the results.
For example, let's say a pollster wants to understand the political preferences of voters in a particular city. If they only survey 50 people, the sample may not accurately reflect the larger population, and the margin of error could be high. However, if they survey 500 or even 1000 people, the results are more likely to provide a reliable estimate of the overall population's preferences.
Therefore, to decrease sample error, pollsters should increase the number of respondents in their surveys or polls. This approach helps to ensure a more accurate representation of the population's views and minimize the potential for misleading or biased results.

The expression is in a+bi form where,
a = 12/13
b = 18/13
================================================
Work Shown:
Multiply top and bottom by 3-2i, which is the conjugate of the original denominator. This will make the denominator go from a nonreal complex number to a purely real number.
\(\frac{6i}{3+2i}\\\\\\\frac{6i(3-2i)}{(3+2i)(3-2i)}\\\\\\\frac{18i-12i^2}{(3)^2-(2i)^2}\\\\\\\frac{18i-12i^2}{9-4i^2}\\\\\\\frac{18i-12(-1)}{9-4(-1)}\\\\\\\frac{18i+12}{9+4}\\\\\\\frac{12+18i}{13}\\\\\\\frac{12}{13}+\frac{18}{13}i\\\\\\\)
The last expression is in a+bi form where a = 12/13 and b = 18/13
Keep in mind that \(i = \sqrt{-1}\) has both sides square to \(i^2 = -1\). Also, I'm using the difference of squares rule to go from \((3+2i)(3-2i)\) to \((3)^2 - (2i)^2\).

Step-by-step explanation:
The formula to use in solving this problem is given as the Combination formula
The Combination formula is given as
C(n , r) = nCr = n!/r! (n - r)!
We are told that a food bakery has 12 pies unsold at the end of the day which they intend to share to 6 food banks
n = 12, r = 6
In order to ensure that at least 1 food bank gets 1 pie, we have:
n - 1 = 12 - 1 = 11
r - 1 = 6 - 1 = 5
Hence,
C(11, 5) = 11C5
= 11!/ 5! ×(11 - 5)!
= 11!/5! × 6!

suppose that people's heights (in centimeters) are normally distributed, with a mean of 170 and a standard deviation of 5. we find the heights of 90 people. (you may need to use the standard normal distribution table. round your answers to the nearest whole number.) (a) how many would you expect to be between 160 and 180 cm tall? incorrect: your answer is incorrect. people (b) how many would you expect to be taller than 165 cm?
Answers
Using the concepts of standard normal distribution,43 people height is in between 160 and 180 and 31 people height is taller than 165cm
The standard normal distribution is actually of the forms of the normal distribution. It occurs when normal random variable has a mean equal to zero and a standard deviation equal to one. Or a normal distribution with a mean 0 and standard deviation of 1 is known as the standard normal distribution. Also, the standard normal distribution is concentrated at zero, and the standard deviation gives the degree to which a given measurement deviates from the mean.
Now, we find the Z score of the given heights range
We know that Z score is given by formula
Z=(\(\frac{X-\alpha }{\beta }\))
where X is normal random variable,\(\alpha\) is mean of given sample and \(\beta\) is standard deviation of given sample.
Therefore, Z score is
z(160) = (170-160)/5 = 2
z(180) = (180-170)/5 = 2
P(160<= x <=180) = P(2<= z <=2) = 0.4772(from standard distribution table)
Therefore for 90 people=90×0.4772= 43 people after rounded up.
b) Similarly, we need to find Z value for people height greater than 165 cm.
Therefore, by using the above formula, we get
z(165) = (170-165)/5 = 1
P(x > 165) = P(z > 1) = 0.3438(from standard distribution table)
Therefore, for 90 people=0.3438×90=31 after rounded up
Hence, number of people whose height is in between 160 and 180cm is 43 and number of people whose height greater than 165cm is 31

THANK YOU!!
Answers
Answer:
Part A)
\(390=(15+x)(13+x)\)
Part B)
Approximately 18.77 feet long by 20.77 feet wide.
Step-by-step explanation:
Currently, the patio is 13 feet long by 15 feet wide. Therefore, the area right now is:
\(A=13(15)=195\text{ feet}^2\)
We will increase the length and width of the patio by the same amount such that the new area is double the previous amount.
Part 1)
The previous area is 195. Therefore, we would like to the new area to be twice of that. Hence, the new area is:
\(A=2(195)=390\)
We will increase the length and the width by the same amount. Let’s call this amount x. Then by the area formula (A=bh), we can write:
\(390=(15+x)(13+x)\)
390 represents the doubled area. (15+x) is the width after the increase x, and (13+x) is the length after the same x increment.
Part 2)
So, we will solve for x. First, expand:
\(390=195+15x+13x+x^2\)
Simplify:
\(x^2+28x+195=390\)
Subtract 390 from both sides:
\(x^2+28x-195=0\)
This is a quadratic. Hence, we can use the quadratic formula:
\(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)
Our a=1, b=28, and c=-195. Hence:
\(x=\frac{-28\pm\sqrt{(28)^2-4(1)(-195)}}{2(1)}\)
Evaluate:
\(x=\frac{-28\pm\sqrt{1564}}{2}\)
Simplify the square root:
\(\sqrt{1564}=\sqrt{4}\cdot\sqrt{391}=2\sqrt{391}\)
Hence:
\(x=\frac{-28\pm2\sqrt{391}}{2}\\\)
Simplify:
\(x=-14+\sqrt{391} \text{ or } -14-\sqrt{391}\)
Approximate:
\(x\approx5.77\text{ or } x\approx-33.77\)
In this case, we can reject the negative solution.
Hence, the value of x is 5.77.
This means that we should increase the our length and width by 5.77.
Hence, the new length will be 13+5.77 or about 18.77.
And our new width will be 15+5.77 or about 20.77.
So, the new dimensions is approximately 18.77 by 20.77
