If <1 and <2 are vertical angles and m<22 = 180°, find m<1

Answers

Answer 1

If ∠1 and ∠2 are vertical angles and m∠22 = 180°, then m∠1 = 90°

Vertical angles are pairs of angles that are opposite to each other when two lines intersect. Vertical angles are always equal in measure. Therefore, if ∠1 and ∠2 are vertical angles, then:

∠1 = ∠2

We are also given that m∠22 has a measure of 180°. Since ∠1 and ∠2 are vertical angles, they form a straight line, and their measures add up to 180°. Therefore:

∠1 + ∠2 = 180°

Since ∠1  = ∠2, we can substitute ∠1 for ∠2 in the above equation:

∠1 + ∠1 = 180°

Simplifying the equation, we get:

2∠1 = 180°

Dividing both sides by 2, we get:

∠1 = 90°

Therefore, ∠1 has a measure of 90°.

The daily high temperatures in degrees Fahrenheit in Allentown, PA, for a period of 10 days are shown below. 76 80 89 96 98 100 98 91 89 82 Which statement correctly describes the data?
A the median value is 98
B the upper quartile value is 96
C the lower quartile vlue is 76
d the interquartile range is 16​

Answers

Answer:

the only correct statement is B: the upper quartile value is 96.

Step-by-step explanation:

First, let's put the temperatures in order: 76, 80, 82, 89, 89, 91, 96, 98, 98, 100.

A. To find the median, we need to find the middle value in the ordered set of data. Since there are an even number of values, we take the average of the two middle values. The two middle values are 89 and 91, so the median is (89+91)/2 = 90. Therefore, statement A is false.

B. To find the upper quartile, we need to find the value that separates the highest 25% of the data from the rest. Since there are 10 values, the upper quartile is the 7th value when the data is ordered. The 7th value is 96, so statement B is true.

C. To find the lower quartile, we need to find the value that separates the lowest 25% of the data from the rest. Since there are 10 values, the lower quartile is the 3rd value when the data is ordered. The 3rd value is 82, so statement C is false.

D. The interquartile range is the difference between the upper quartile and the lower quartile. From our previous calculations, we know that the upper quartile is 96 and the lower quartile is 82. Therefore, the interquartile range is 96-82 = 14. Statement D is false.

Therefore, the only correct statement is B: the upper quartile value is 96.

The measures of the angles x and y are:

m∠y =  = 148°

m∠x  = 153°

How to get the measures of the angles?

Remember that:

The sum of two adjacent angles is always 180°

The sym of the interior angles of a triangle is always 180°

With the first rule, we know that:

m∠a + m∠y = 180°

And we know that m∠a = 32°, then:

32° +  m∠y = 180°

m∠y = 180° - 32° = 148°

Now, the angle at b is 59°, then the top angle of the triangle is:

180° - 59° = 121°

And the left angle in the triangle is A, such that:

A + 121° + 32° = 180°

A = 180° - 32° - 121° = 27°

And that angle plus the measure of x must be 180°, then:

m∠x + 27° = 180°

m∠x = 180° - 27° = 153°

true or false: if one assumes two or more groups are from separate populations then the different groups are considered related samples for conducting statistical tests.

Answers

False. If one assumes two or more groups are from separate populations, the different groups are considered unrelated or independent samples for conducting statistical tests.

In statistical analysis, there are two types of samples: related (also known as dependent or paired) and unrelated (also known as independent or unpaired). Related samples are taken from the same population, often involving before-and-after measurements, repeated measures, or matched pairs.

Unrelated samples are taken from separate populations, with no inherent connection between the samples.
When you want to compare two or more groups, the choice of related or unrelated samples will determine the type of statistical test you should use.

For related samples, you can use tests like the paired t-test, Wilcoxon signed-rank test, or repeated measures ANOVA. For unrelated samples, you can use tests like the independent t-test, Mann-Whitney U test, or one-way ANOVA.
In summary, assuming that two or more groups are from separate populations means they are considered unrelated or independent samples, not related samples, for conducting statistical tests.

The choice of related or unrelated samples will guide you in selecting the appropriate statistical test for your analysis.

our environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 5.5 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 13 samples is 6.0 ppm with a standard deviation of 0.9 . assume the population is normally distributed. does the data support the researcher's claim at the 0.05 level? make the decision to reject or fail to reject the null hypothesis.

Answers

The data support the researcher's claim that the current ozone level is not at a normal level, at the 0.05 level of significance, concluded with the help of a one-sample t-test.

To test whether the current ozone level is significantly different from the normal level of 5.5 ppm, we can use a one-sample t-test.

The null hypothesis is that the mean ozone level is equal to 5.5 ppm:

H0: mu = 5.5

The alternative theory is that the average ozone level exceeds 5.5 ppm:

Ha: mu > 5.5

The significance threshold will be set at 0.05.

t = (x - mu) / (s / sqrt(n)) is the test statistic for a one-sample t-test.

where x is the sample mean, is the hypothesized population mean, s represents the sample standard deviation, and n represents the sample size.

When we substitute the provided values, we get:

t = (6.0 - 5.5) / (0.9 / sqrt(13)) = 1.936

Using a t-table with 12 degrees of freedom (n-1=13-1=12) and a significance level of 0.05, the critical value is 1.782. Since our calculated t-value (1.936) is greater than the critical value (1.782), we reject the null hypothesis.

Therefore, we can conclude that the data support the researcher's claim that the current ozone level is not at a normal level, at the 0.05 level of significance.

What is the completely factor simplified form of the rational expression below?

A. x²+2x-15/x+5
B. x²+2x+15x/+5
C.x+5
D. x-3

Answers

Answer:A

Step-by-step explanation:

To simplify the rational expression (x²+6x)/(x+5) + (4x+15)/(x+5), we first factor the numerator of the first fraction as x(x+6). Then, we factor the numerator of the second fraction as 4(x+3). Now, we can combine the fractions by finding a common denominator of (x+5) and adding the numerators:

(x²+6x)/(x+5) + (4x+15)/(x+5) = (x(x+6) + 4(x+3))/(x+5)

Simplifying the numerator further, we get:

(x²+6x + 4x + 12)/(x+5) = (x²+10x+12)/(x+5)

Now we can factor the numerator by finding two numbers that multiply to 12 and add to 10. Those numbers are 2 and 6. So we can write:

(x²+10x+12)/(x+5) = (x+2)(x+6)/(x+5)

Therefore, the completely factored and simplified form of the given rational expression is (x+2)(x+6)/(x+5). So the answer is A.

The fourth Arithmetic mean is -4.

To find the fourth arithmetic mean between -24 and 16, first calculate the common difference between the terms. The formula for this is:

Common difference (d) = (Final term - Initial term) / (Number of means + 1)

In this case, the initial term (a) is -24, the final term (b) is 16, and the number of arithmetic means (n) is 7.

d = (16 - (-24)) / (7 + 1)

d = (16 + 24) / 8

d = 40 / 8

d = 5

Now, you can find the fourth arithmetic mean (a_4) using the formula:

Answers

The probability that the student will get exactly four correct answers is approximately 0.1706

To solve this problem, we can use the binomial distribution, which gives the probability of getting a certain number of successes in a fixed number of independent trials, where each trial has the same probability of success.

In this case, each question has three possible answers, only one of which is correct. So the probability of getting a correct answer by guessing is 1/3.

Let X be the number of correct answers out of 8. Then X follows a binomial distribution with n=8 and p=1/3.

To get exactly four correct answers, we need to get four successes and four failures in any order. The number of ways to choose four questions to answer correctly is 8 choose 4 (written as 8C4), which is equal to 70. The probability of getting four successes and four failures is therefore

P(X=4) = (8C4) × (1/3)^4 × (2/3)^4

Answers

The probability that the sampling distribution of sample proportions is less than 91% is very low, approximately 0.0000025.

The sample size is n = 81 and the population proportion is p = 0.95. The mean of the sampling distribution of sample proportions is equal to the population proportion, which is 0.95. The standard deviation of the sampling distribution of sample proportions is given by the formula sqrt(p*(1-p)/n), which is approximately 0.03. Thus, the z-score corresponding to a sample proportion of 0.91 is (0.91 - 0.95)/0.03 = -1.33. The probability that the sampling distribution of sample proportions is less than 91% is the same as the probability that a standard normal variable is less than -1.33, which is approximately 0.0000025 (using a standard normal distribution table or calculator).

the equation of the circle with center (0,-3) containing the point (√32,-2) is x² + (y + 3)² = 33.

How to solve an equation?

To determine the equation of a circle, we need to know the coordinates of its center and the radius. The formula for the equation of a circle is (x - a)² + (y - b)² = r², where (a, b) represents the center of the circle and r represents its radius.

In this case, the center of the circle is given as (0,-3), so we can substitute these values into the formula: (x - 0)² + (y - (-3))² = r²

To find the value of r, we need to use the fact that the circle contains the point (√32,-2). We know that any point on the circle will be a distance r away from the center, so we can use the distance formula to find r.

The distance between the center (0,-3) and the point (√32,-2) is:

sqrt[(√32 - 0)² + (-2 - (-3))²] = sqrt[32 + 1] = sqrt(33)

Therefore, the radius r is sqrt(33).

Substituting this value into the equation of the circle, we get:

(x - 0)² + (y - (-3))² = (sqrt(33))²

Simplifying this equation, we get:

x² + (y + 3)² = 33

So the equation of the circle with center (0,-3) containing the point (√32,-2) is x² + (y + 3)² = 33.

To calculate the difference in the number of paychecks, we can subtract the number of paychecks Ralph receives from the number Alice receives:

Number of paychecks for Alice - Number of paychecks for Ralph = 26 - 24 = 2

Therefore, Alice receives 2 more paychecks in a year compared to Ralph.

Answers

The probability that the weight limit will be exceeded when there are exactly 40 passengers and 3 crew members on board is 0.031.

Mean = 196 × 43

Mean = 8428

Std. Dev. = 63 × √(43)

Std. Dev. = 63 × 6.56

Std. Dev. = 413.28

Here, μ = 8428, σ = 413.1186 and x = 9200. We must calculate P(X ≥ 9200).

he central limit theorem states that, for a sufficiently large sample size, the sample mean of all observations will be approximately normally distributed, regardless of the distribution of the population from which it was sampled.

The Central Limit Theorem is used to get the associated z-value.

z = (x - μ)/σ

z = (9200 - 8428)/413.28

z = 772/413.28

z = 1.87

Therefore,

P(X ≥ 9200) = P(z ≤ (9200 - 8428)/413.1186)

P(X ≥ 9200) = P(z ≤ 772/413.1186)

P(X ≥ 9200) = P(z ≥ 1.87)

Some states, such as Oregon, do not have a state imposed sales tax like other states. However, the state government has to make up that financial difference in another way. Which option is better for the individual: a state with sales tax or a state without sales tax? Explain why. Which option is better for the state government? Explain why. Give an opinion in your own words, using complete sentences.

Answers

A state with a sales tax is a better option for both individuals and state governments.

WHAT IS SLES TAX?

A state without a sales tax may seem preferable since they do not have to pay additional taxes on purchases. However, in such states, the government often imposes higher income taxes or property taxes to compensate for the lack of sales tax revenue. Therefore, it ultimately depends on the individual's financial situation and spending habits.

From the state government's perspective, having a sales tax is generally more beneficial as it provides a consistent and reliable revenue stream. Sales tax revenue is collected on a regular basis and is not subject to fluctuations in the economy or changes in demographics. Additionally, sales tax revenue is not as heavily reliant on the state's residents and can be partially collected from tourists and visitors who make purchases within the state.

In my opinion, a state with a sales tax is a better option for both individuals and state governments. While paying additional taxes may not seem appealing, it allows the state to fund essential services such as education, healthcare, and infrastructure. Additionally, sales tax revenue is spread across a wider population, making it more equitable and less burdensome on individual taxpayers. Overall, having a sales tax system in place helps to ensure that the state government can continue to provide essential services and maintain a stable economy.

Ten cc of a solution of acid and water is 30% acid. I wish to dilute the acid in the mixture by adding water to make a mixture that is only 6% acid. How much pure water must I add to accomplish this?

Answers

Let's call the amount of pure acid in the original 10cc solution A.

A = 0.3(10cc) = 3cc

Let's also call the amount of pure water we need to add to dilute the solution by x cc.

So after we add x cc of water, we have a new solution with a total volume of (10 + x) cc, and the amount of pure acid in the new solution is still 3cc.

To have a 6% acid solution, we know that:

3cc / (10 + x) cc = 0.06

Solving for x:

3cc = 0.06(10 + x)cc

3cc = 0.6 + 0.06x cc

2.4cc = 0.06x cc

x = 40cc

So we need to add 40cc of pure water to dilute the 10cc 30% acid solution to a 6% acid solution.

Model Real Life You arrange eight chairs around a circle that has eight sections. Find the sum of the angle measures of 7 of the sections.

Answers

The sum οf the angle measures οf 7 οf the sectiοns is 315 degrees.

What are Angles?

An angle is a geοmetric figure fοrmed by twο rays that share a cοmmοn endpοint, called the vertex. It is usually measured in degrees οr radians and describes the amοunt οf rοtatiοn between the twο rays.

If we arrange eight chairs arοund a circle that has eight sectiοns, each sectiοn will have a central angle οf 360 degrees / 8 = 45 degrees.

Tο find the sum οf the angle measures οf 7 οf the sectiοns, we can add the central angles οf thοse 7 sectiοns:

7 x 45 degrees = 315 degrees.

Therefοre, the sum οf the angle measures οf 7 οf the sectiοns is 315 degrees.
