Answer:

x = 25

Step-by-step explanation:

Angle 1 = 2x + 10

Angle 2 = 4x + 20

These two angles are going to add up to 180 because 180 is a straight line so we get the equation:

2x + 10 + 4x + 20 = 180

6x + 10 + 20 = 180

6x + 30 = 180

6x = 150

x = 25

The probability that a homebuilder takes 200 days or less to complete a house is approximately 0.8238, or 82.38%.

Explanation :

To answer this question, we can use the concept of the z-score. The z-score tells us how many standard deviations a data point is from the mean.

Let's calculate the z-score for a completion time of 200 days:
z = (x - μ) / σ
where x is the completion time, μ is the mean, and σ is the standard deviation.
Plugging in the values, we get:
z = (200 - 176.7) / 24.8 = 0.93

To find the probability associated with this z-score, we can use a z-table or a calculator. In this case, the probability is 0.8238.

This means that there is an 82.38% chance that the completion time of a house will be 200 days or less, given that the completion time follows a normal distribution with a mean of 176.7 days and a standard deviation of 24.8 days.

The required proof that the triangles ΔLMN and ΔPQR are similar is explained below in the solution part.

To prove that the triangles ΔLMN and ΔPQR are similar, we need to perform a sequence of transformations that preserve the shape and size of the triangles.

One possible sequence of transformations is:

Rotate ΔLMN clockwise 90 degrees about point L.

Dilate the resulting image with a center of dilation at point L and a scale factor between 0 and 1 to obtain the triangle ΔPQR.

Here, the scale factor is between 0 and 1 because ΔPQR is smaller than the triangle ΔLMN.

after 14 years, there will be approximately 1.97g of the radioactive substance remaining.

To solve this problem, we can use the concept of exponential decay for radioactive substances. The decay of a radioactive substance can be modeled by the equation:

N(t) = N₀ * e^(-kt),

where N(t) is the amount of substance at time t, N₀ is the initial amount of substance, e is the base of the natural logarithm, k is the decay constant, and t is the time elapsed.

In this case, we are given that the initial amount N₀ is 10g and the amount after 9 years N(9) is 5g. We can use this information to find the value of k.

5 = 10 * e^(-9k).

Divide both sides of the equation by 10:

0.5 = e^(-9k).

Take the natural logarithm of both sides:

ln(0.5) = -9k.

Solve for k:

k = ln(0.5) / -9.

Now that we have the value of k, we can use it to find the amount of substance after 14 years, N(14):

N(14) = N₀ * e^(-kt).

N(14) = 10 * e^(-ln(0.5) / -9 * 14).

N(14) = 10 * e^(14 * ln(0.5) / 9).

N(14) ≈ 10 * 0.197 = 1.97.

Therefore, after 14 years, there will be approximately 1.97g of the radioactive substance remaining.

The survey being mailed out by an HIV/AIDS prevention group to people randomly selected from a commercial mailing list may have potential harms to participants.

Disclosure of sensitive information: One potential harm to participants is the disclosure of sensitive information. Since the survey is related to HIV/AIDS prevention, it may ask questions about personal health status, sexual behavior, or other sensitive topics. If this information were to be disclosed unintentionally or without proper safeguards, it could lead to stigmatization, discrimination, or other negative consequences for the participants.

Violation of privacy: Another potential harm is the violation of privacy. Participants may have concerns about their personal information being shared or used inappropriately. If the survey does not have proper data protection measures in place, such as encryption or secure storage, participants' privacy could be compromised.

Physical harm: Physical harm is also a potential risk, although it may be less likely in the context of a survey being mailed out. However, if the survey includes any physical samples or requires participants to perform certain actions that could be harmful (e.g., self-administering a medical test without proper instructions), there is a possibility of physical harm.

Inconvenience: The option that does not pose a potential harm to participants is inconvenience. While participating in a survey may require some time and effort from participants, it is generally considered a minor inconvenience compared to the potential risks mentioned above.

In conclusion, the potential harms to participants in this scenario include disclosure of sensitive information, violation of privacy, and physical harm. Inconvenience, on the other hand, is not considered a significant potential harm.

Answer:

A = $2,800 B = $12,600

Step-by-step explanation:

a. How much will the insurance company pay?

The liability insurance will cover the damages to the other car ($1,400) and the personal injury claims ($12,800 + $9,200) up to the limit of $10,000. So the insurance company will pay $10,000.

The collision insurance covers the damage to Rusty's own car, minus the $300 deductible, so the insurance company will pay $3,100 - $300 = $2,800.

Therefore, the insurance company will pay a total of $10,000 + $2,800 = $12,800.

b. What is Rusty’s share of the responsibility?

Rusty is responsible for paying the remaining amount not covered by insurance, which is $1,400 + $3,100 + $12,800 + $9,200 - $12,800 = $12,600.

Therefore, Rusty's share of the responsibility is $12,600.

If a series an is defined by the equations a1 = 2 an+1 = 3 + cos(n) / √n · an, then  Σan is absolutely convergent. Therefore, the answer is: a) absolutely convergent.

To determine whether Σan is absolutely convergent, conditionally convergent, or divergent, we need to analyze the behavior of the series as n approaches infinity.

First, let's look at the absolute value of the terms in the series:

|an| = |2 × (3 + cos(n) / √n · an-1)|
    = |6 + 2cos(n) / √n · an-1|

Next, we can use the Comparison Test by comparing the series to a known convergent or divergent series. Let's compare the series to the p-series:

∑1/n^p

where p = 3/2. This series is known to converge by the p-test.

Now, we can rewrite the absolute value of an in terms of the p-series:

|an| = |6 + 2cos(n) / √n · an-1|
     ≤ |6 + 2 / √n · an-1|          (since cos(n) ≤ 1)
     ≤ 6 + 2 / √n · |an-1|           (using the triangle inequality)

Therefore, we have:

|an| ≤ 6 + 2 / √n · |an-1|

If we take the limit of both sides as n approaches infinity, we get:

lim n→∞ (6 + 2 / √n · |an-1|) / |an-1|
= lim n→∞ (6 / |an-1|) + (2 / (√n · |an-1|))
= 6 / lim n→∞ |an-1| + 0

Since lim n→∞ |an-1| exists (as an is a well-defined series), we can conclude that the limit is a finite number. Therefore, by the Comparison Test, Σ|an| converges.

Finally, we can use the Ratio Test to determine whether Σan converges absolutely or conditionally:

lim n→∞ |an+1 / an|
= lim n→∞ |(3 + cos(n+1) / √(n+1) · an) / an|
= lim n→∞ |(3 + cos(n+1)) / (√(n+1) · an)|

Using L'Hopital's Rule, we can show that the limit of the cosine term is 0, and the limit of the denominator is infinity. Therefore, the limit of the ratio is 0.

Since the limit of the ratio is less than 1, we can conclude that Σan converges absolutely.

Therefore, the answer is: a) absolutely convergent.

The p-value for testing H0 (null hypothesis) versus Ha (alternative hypothesis) is 0.0038. We need to determine whether H0 would be rejected at different significance levels: α = 0.10, α = 0.05, α = 0.01, and α = 0.001.

To make the decision, we compare the p-value with the chosen significance level. If the p-value is less than or equal to the significance level, we reject H0. Otherwise, we fail to reject H0.

At α = 0.10: Since the p-value (0.0038) is less than 0.10, we reject H0.

At α = 0.05: Since the p-value (0.0038) is less than 0.05, we reject H0.

At α = 0.01: Since the p-value (0.0038) is greater than 0.01, we fail to reject H0.

At α = 0.001: Since the p-value (0.0038) is greater than 0.001, we fail to reject H0.

In summary:

H0 would be rejected at α = 0.10 and α = 0.05.

H0 would not be rejected at α = 0.01 and α = 0.001.

Please note that the decision to reject or fail to reject the null hypothesis depends on the chosen significance level, and different levels of significance can lead to different conclusions.

Answer:

A) 29men

B) 91cm

C) 13cm

Step-by-step explanation:

Men with waist of 85cm = 11

A.) Men with waist of more than 85cm = (total number of men - 11) = (40 - 11) = 29men

B.) median waist :

Median = (n) / 2

Where n = number of observations

Median = (40) / 2 = 40/2 = 20th

Taking the intersection of the 20th point on the x-axis,

Median waist = 91cm

C.) Interquartile range(IQR) = (Q3 - Q1)

Q3 = 3/4(n)

Q3 = 0.75 × 40 = 30

Q3 = 97cm

Q1 = 1/4(n)

Q1 = 0.25 × 40 = 10

Q1 = 84cm

Let "b" be the total bill before the tip.

The tip was 18% of the bill, or 0.18 * b.

The tip was also $4.50, so we can set up the equation 0.18b = $4.50.

Solving for b, we get:

0.18b = $4.50

b = $4.50 / 0.18

b = $25

Therefore, Sierra's total bill before the tip was $25.

The expected value in a binomial situation with n = 18 and π = 0.60 is E(X) = np = 18 * 0.60 = 10.8.

In a binomial situation, the expected value, denoted as E(X), represents the average or mean outcome of a random variable X. It is calculated by multiplying the number of trials, denoted as n, by the probability of success for each trial, denoted as π.

In this case, we are given n = 18 and π = 0.60. To find the expected value, we multiply the number of trials, 18, by the probability of success, 0.60.

n = 18 (number of trials)

π = 0.60 (probability of success for each trial)

To find the expected value:

E(X) = np

Substitute the given values:

E(X) = 18 * 0.60

To calculate Sasha's probability of winning, we need to determine how many desired outcomes she has. In this game, Sasha needs to spin a number higher than both of her friends' spins, which means she needs to spin a number greater than 1 and 4.

Let's analyze the spinner pictured. From the image, we can see that the spinner has numbers ranging from 1 to 6. Since Sasha needs to spin a number higher than 4, she has two options: 5 or 6.

Now, let's consider the desired outcomes. Sasha has two desired outcomes, which are spinning a 5 or spinning a 6. If she spins either of these numbers, she will have a number higher than both of her friends and win the game.

To calculate Sasha's probability of winning, we need to divide the number of desired outcomes by the total number of possible outcomes. In this case, the total number of possible outcomes is the number of sections on the spinner, which is 6.
