Select one:
a. 25%
b. 20%
c. 12%
d. 10%

Answers

Answer 1
Let's assume Michael earned $100.

Albert earned 20% less than Michael, which is $80.

Peter earned 40% more than Albert, which is $80 + 0.4($80) = $112.

So, Peter earned $112 - $100 = $12 more than Michael.

Therefore, the percentage that Peter earned more than Michael is (12/100) x 100% = 12%.

The answer is c. 12%.

When a plant is not strong enough to support its own weight, what is most likely the problem? O A. The plant is producing too many polysaccharides. B. The plant is not producing enough cellulose. C. The plant needs more monosaccharides to add strength. D. The plant does not have enough starch. ✔ Correct




(D) The plant is not producing enough cellulose​

Answers

Yes, you are correct. When a plant is not strong enough to support its own weight, the most likely problem is that the plant is not producing enough cellulose. Cellulose is a complex carbohydrate that provides structural support to plant cell walls. It forms strong fibers that help plants maintain their shape and rigidity. If a plant does not produce enough cellulose, its cell walls may be weak, leading to a lack of structural support and an inability to withstand the weight of the plant.[tex][/tex]

who made the state test in 1837-48

Answers

Horace Mann made the state test in 1837-48

A 2018 poll of 3612 randomly selected users of a social media site found that 1704 get most of their news about world events on the site. Research done in 2013 found that only 46% of all the site users reported getting their news about world events on this site.
a. Does this sample give evidence that the proportion of site users who get their world news on this site has changed since 2013? Carry out a hypothesis test and use a 0.05 significance level.
b. After conducting the hypothesis test, a further question one might ask is what proportion of all of the site users get most of their news about world events on the site in 2018. Use the sample data to construct a 95% confidence interval for the population proportion. How does your confidence interval support your hypothesis test conclusion?

Answers

a. To test whether the proportion of site users who get their world news on this site has changed since 2013, we can perform a hypothesis test. Let p be the true population proportion of site users who get their world news on this site in 2018. Then the null hypothesis is H0: p = 0.46, and the alternative hypothesis is Ha: p ≠ 0.46. We will use a two-tailed z-test with a 0.05 significance level.

Using the sample data, the sample proportion of site users who get their world news on this site is 1704/3612 = 0.471. The standard error of the sample proportion is sqrt(0.46*0.54/3612) = 0.013. The z-score for the sample proportion is (0.471 - 0.46) / 0.013 = 0.846. The corresponding p-value for this test is P(|Z| > 0.846) = 0.397 > 0.05.

Since the p-value is greater than 0.05, we fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that the proportion of site users who get their world news on this site has changed since 2013.

b. To construct a 95% confidence interval for the population proportion of site users who get their world news on this site in 2018, we can use the sample proportion and the margin of error formula:

Margin of error = z*sqrt(p*(1-p)/n)

where z = 1.96 for a 95% confidence level, p = 0.471, and n = 3612.

Plugging in these values, we get:

Margin of error = 1.96*sqrt(0.471*(1-0.471)/3612) = 0.014

Therefore, the 95% confidence interval for the population proportion is:

0.471 ± 0.014, or (0.457, 0.485)

Since the null hypothesis in part (a) was that the proportion of site users who get their world news on this site is 0.46, and the confidence interval does not contain 0.46, this supports the conclusion of the hypothesis test that there is not enough evidence to suggest that the proportion has changed since 2013.

(If this doesn’t seem right to you make sure you comment!)
a. To test whether the proportion of site users who get their world news on this site has changed since 2013, we can use a hypothesis test with the following hypotheses:

Null hypothesis: The proportion of site users who get their world news on this site is equal to 0.46.
Alternative hypothesis: The proportion of site users who get their world news on this site is greater than 0.46.

We will use a significance level of 0.05.

The sample proportion is 1704/3612 = 0.471. We can assume that the sample is large enough to use a normal distribution. The test statistic is:

z = (0.471 - 0.46) / sqrt(0.46 * 0.54 / 3612) = 3.87

The p-value for this test is P(Z > 3.87) = 0.00005, which is much smaller than the significance level of 0.05. Therefore, we reject the null hypothesis and conclude that the proportion of site users who get their world news on this site has increased since 2013.

b. To construct a 95% confidence interval for the population proportion, we can use the sample proportion and the margin of error formula:

Margin of error = z* * sqrt(p*(1-p)/n)

where z* is the critical value for a 95% confidence level, p is the sample proportion, and n is the sample size.

The critical value for a 95% confidence level is 1.96. Substituting the values, we get:

Margin of error = 1.96 * sqrt(0.471 * 0.529 / 3612) = 0.018

The 95% confidence interval is therefore:

0.471 ± 0.018

or

(0.453, 0.489)

This interval does not include the null hypothesis value of 0.46, which supports our conclusion from the hypothesis test that the proportion of site users who get their world news on this site has increased since 2013.

How does lack of community participation contribute to poor service delivery

Answers

Answer:

In summary, lack of community participation can contribute to poor service delivery by limiting feedback, inadequate needs assessment, limited accountability, and limited resources. Therefore, it is important to involve communities in the planning, implementation, and monitoring of public services to improve service delivery.

Explanation:

Lack of Feedback: If the community is not involved in the planning, implementation, and monitoring of public services, it becomes difficult for authorities to obtain feedback on the effectiveness of the services provided. Without feedback, it is difficult to identify areas that need improvement, and this can result in poor service delivery.

Inadequate Needs Assessment: When community members are not involved in the needs assessment process, it becomes difficult to identify the specific needs of the community. This can result in services that are not tailored to the specific needs of the community, leading to poor service delivery.

Limited Accountability: Community participation provides an avenue for holding service providers accountable for their actions. When community members are not involved in monitoring the delivery of services, it becomes difficult to hold service providers accountable for their actions. This can result in poor service delivery, as service providers may not be held accountable for their shortcomings.

Limited Resources: Community participation can also lead to the identification of additional resources that can be used to support the delivery of public services. When community members are not involved, it becomes difficult to identify additional resources that can be used to support service delivery. This can result in poor service delivery due to limited resources.

How do ocean currents effect the air temperature for Luderitz and Florianopolis?

Answers

Answer:

Ocean currents can have a significant effect on air temperature in coastal areas like Luderitz and Florianopolis.

Luderitz, located on the Atlantic coast of Namibia, is influenced by the cold Benguela Current which flows northward along the coast from Antarctica. This current cools the air above it, resulting in lower air temperatures in Luderitz compared to other locations at a similar latitude.

Florianopolis, on the other hand, is located on the Atlantic coast of Brazil and is influenced by the warm Brazil Current, which flows southward along the coast from the equator. This current warms the air above it, resulting in higher air temperatures in Florianopolis compared to other locations at a similar latitude.

Therefore, in both cases, the ocean currents play a significant role in determining the air temperature of the coastal areas.

Answers

Answer:

No

Explanation:

No, it is not true. While the double-entry system is an important and widely used method in accounting, there is evidence of accounting practices dating back to ancient civilizations such as the Babylonians and Egyptians. The ancient Greeks and Romans also had various forms of accounting and record-keeping. However, the double-entry system as we know it today was first described by Italian mathematician Luca Pacioli in his book "Summa de Arithmetica, Geometria, Proportioni et Proportionalità" in the 15th century.

Before the radio and telephone were invented, some groups used patterns of drumbeats to send information to one another.


Which statement ,begin emphasis,best,end emphasis, explains how the patterns of drumbeats transferred information from one group to another?

Answer options with 4 options

A.

The different shapes of the drums produced different sounds.

B.

The pattern of drumbeats represented different words or phrases.

C.

The groups used different drums during different times of the year.

D.

The drumbeats were so loud that they could be heard from great distances.

Answers

The statement that best explains how patterns of drumbeats transferred information from one group to another is option B: "The pattern of drumbeats represented different words or phrases."

Groups that used drumbeats to communicate developed complex systems of rhythms and patterns that could convey specific meanings, much like a language. Different rhythms and patterns were associated with different words, phrases, or messages.

For example, a certain pattern of beats might represent a warning of danger, while another pattern might indicate the arrival of an important visitor. By varying the rhythm and duration of the beats, and by using different combinations of beats, the drummers could convey a wide range of meanings and messages.

Drum communication was particularly useful for groups that lived in areas with rugged terrain or dense forests, where it was difficult to communicate over long distances using spoken language.

The sound of the drums could carry for miles and was easily distinguishable from other sounds in the environment. In addition, because the drummers could use a code that was known only to their group, they could communicate privately without fear of interception or misinterpretation by outsiders.

In conclusion, the patterns of drumbeats used by certain groups to send information to one another represented different words or phrases. These rhythms and patterns allowed the drummers to convey a wide range of messages over long distances and in difficult terrain.

Create a system of equations represented by these two lines, and find the solution to the system. Move a number to each box to complete the equations, and move a number to each line to create the ordered pair.Response area with 6 blank spaces equals Blank space 1 emptyx plus Blank space 2 empty y equals Blank space 3 emptyx plus Blank space 4 empty (Blank space 5 empty, Blank space 6 empty)

Answers

To create a system of equations represented by two lines, we first need to determine the equations of these lines in the slope-intercept form, which is y = mx + b, where m is the slope of the line and b is the y-intercept.

Let's say the two lines are represented by:

Line 1: Blank space 1 emptyx + Blank space 2 emptyy = Blank space 3 empty

Line 2: Blank space 4 emptyx + Blank space 5 emptyy = Blank space 6 empty

Let's multiply the first equation by Blank space 5 empty and the second equation by -Blank space 2 empty, so we get:

Line 1: Blank space 1 emptyx + Blank space 2 emptyy = Blank space 3 empty

Line 2: -Blank space 4 emptyBlank space 5 emptyx - Blank space 2 emptyBlank space 5 emptyy = -Blank space 6 emptyBlank space 2 empty

Now, if we add these two equations, we can eliminate the y variable:

(Blank space 1 emptyx - Blank space 4 emptyBlank space 5 emptyx) + (Blank space 2 emptyy - Blank space 2 emptyBlank space 5 emptyy) = Blank space 3 empty - Blank space 6 emptyBlank space 2 empty

Simplifying, we get:

(Blank space 1 empty - Blank space 4 emptyBlank space 5 empty) x = Blank space 3 empty - Blank space 6 emptyBlank space 2 empty

Therefore, the solution to the system is:

x = (Blank space 3 empty - Blank space 6 emptyBlank space 2 empty) / (Blank space 1 empty - Blank space 4 emptyBlank space 5 empty)

Now, we need to find the value of y by substituting x into one of the equations. Let's use the first equation:

Blank space 1 emptyx + Blank space 2 emptyy = Blank space 3 empty

Substituting x, we get:

Blank space 1 empty(Blank space 3 empty - Blank space 6 emptyBlank space 2 empty) / (Blank space 1 empty - Blank space 4 emptyBlank space 5 empty) + Blank space 2 emptyy = Blank space 3 empty

Simplifying, we get:

y = (Blank space 3 empty(Blank space 1 empty - Blank space 4 emptyBlank space 5 empty) - Blank space 2 emptyBlank space 6 empty) / (Blank space 1 empty - Blank space 4 emptyBlank space 5 empty)

Therefore, the solution to the system is the ordered pair (x, y) = (Blank space 3 empty - Blank space 6 emptyBlank space 2 empty / Blank space 1 empty - Blank space 4 emptyBlank space 5 empty, (Blank space 3 empty(Blank space 1 empty - Blank space 4 emptyBlank space 5 empty) - Blank space 2 emptyBlank space 6 empty) / (Blank space 1 empty - Blank space 4 emptyBlank space 5 empty)).

According to a research agency, in 25% of marriages, the woman has a bachelor's degree, and the marriage lasts at least 20 years. A census report shows 36% of women have a bachelor's degree. What is the probability a randomly selected marriage will last at least 20 years if the woman has a bachelor's degree? Note: 53% of all marriages last at least 20 Years.

Answers

The probability that a randomly selected marriage will last at least 20 years, given that the woman has a bachelor's degree, the probability cannot be calculated without the specific value for P(A|B).

Let's denote the event A as "the woman has a bachelor's degree" and event B as "the marriage lasts at least 20 years."

According to the research agency, P(A) = 0.25, which represents the probability that a randomly selected marriage involves a woman with a bachelor's degree.

The census report states that P(A') = 0.36, where A' represents the complement of event A, i.e., the probability that a woman does not have a bachelor's degree.

The census report also provides the probability of event B, P(B) = 0.53, which represents the probability that a randomly selected marriage lasts at least 20 years.

We need to find P(B|A), the probability that a marriage lasts at least 20 years given that the woman has a bachelor's degree.

To calculate P(B|A), we use the formula for conditional probability:

P(B|A) = P(A ∩ B) / P(A)

From the given information, we know that P(A ∩ B), the probability that a woman has a bachelor's degree and the marriage lasts at least 20 years, is not provided directly.

However, we can use the concept of joint probability and rearrange the formula as follows:

P(A ∩ B) = P(B) * P(A|B)

P(A|B) represents the probability that the woman has a bachelor's degree given that the marriage lasts at least 20 years.

Since P(A|B) is not given explicitly, we cannot determine it directly from the information provided.

Therefore, without the specific value for P(A|B), we cannot calculate the probability that a randomly selected marriage will last at least 20 years, given that the woman has a bachelor's degree.
