2. What is the independent variable in the study? The degree of beauty and attractiveness of the speakers. In a scientific study, the independent variable is the one that influences a result to happen, in this case, the beauty of the speakers was what influenced the degree of acceptance of the students, around the lecture.
3. What is the dependent variable in the study: The degree of acceptance of students in relation to the lecture. The dependent variable is one that needs to be influenced by the dependent variable in order to be able to evaluate a result. As we can see in the question above, the degree of beauty of the speakers influenced the degree of acceptance of the students in relation to the intelligence and competence of the speakers about the lecture.
4. How did the researchers "operationally define" attractiveness? They made this definition by evaluating the photos of the speakers, taken by other volunteers, who classified the photos as beautiful or ugly.
5. The results were said to be "statistically significant." What does that mean? It means that the acceptance of listeners to a lecture changes in relation to the beauty of the speakers.
6. Give one possible confounding variable in the study: a possible confounding variable would be the content of the lectures. Confounding variables are elements that can influence both the independent and the dependent variable. Thus, a complex or simple subject addressed as content of the lecture could influence both the perception of the beauty of the speakers and the acceptance of the lecture.
7. If the researchers stated that the results had generalizability ", what would that mean? It means that the results can be adopted as correct in any lectures.
8. In the context of the study, how would the researchers "debrief" the participants? They could ask whether they understood the lecture, whether the subject was spoken clearly, whether the speaker shows confidence, whether the speaker looks smart, whether the speaker looks healthy and whether the speaker dominates the subject matter.
9. Give one ethical consideration that would fit this study. (Refer to APA Ethical Guidelines on Blackboard): The confidentiality of volunteers' responses must be maintained. This is an ethical issue that must be respected in this study, according to APA's ethical guidelines.
10 How would another research check the reliability of this study? Reproducing it with the same variables. This should be done, because a reliable study must allow it to be repeated and will be considered true if the same results are observed.
11. If Hawthorne Effect affected the results of the study, what happened? If the Hawthorne Effect happened, the environment in which the volunteers were subjected interfered with the results. This is because the Hawthorne effect relates the physical conditions of an environment to the productivity of volunteers in relation to some factor. In this case, a more or less comfortable environment may have influenced the volunteers' acceptance of the lecture and the speakers.
The diagram shows a wave. The quantity shown is the amplitude. This quantity is directly proportional to which of these other quantities?
A) Energy
B) Frequency
Eliminate
C) Period
D) Wavelength
Answer:
A) Energy
Explanation:
Energy and Amplitude are directly proportional because an increase in energy always results in an increase in amplitude, and vice versa, so they are directly proportional. As for the other options, they are all independant from the amplitude (i.e. Changing them would not result in a change in amplitude e.g. A wave can have a big amplitude and high frequency or a big amplitude and low frequency, as neither affects the other). Therefore it is option A) Energy.

Phoebe knit a hat for a friend. She started with 197 meters of yarn. When she finished, she had 8,200 centimeters of yarn left over. How much yarn did Phoebe use to knit the hat?
Answer: 115 meters
Explanation:
From the question, we are informed that Phoebe knit a hat for a friend and that she started with 197 meters of yarn but when she finished, she had 8,200 centimeters of yarn left over.
First, we have to understand that 100 centimeters equals 1 metre. Therefore, 8200 centimeters of yarn is the same as 8200/100 = 82 meters of yarn.
The yarn that Phoebe use to knit the hat will be:
= 197 meters - 82 meters
= 115 meters

What is the net primary productivity of an algal bed if the gross primary productivity in an algal bed is 7 kcal/m2/yr and respiration is 3 kcal/m2/yr?
Answer:
[tex]NPP = 4\ kcal/m^2/yr[/tex]
Explanation:
Given
[tex]Gross\ Primary\ Productivity, GPP= 7\ kcal/m^2/yr[/tex]
[tex]Respiration, R= 3\ kcal/m^2/yr[/tex]
Required
Determine the Net Primary Productivity (NPP)
NPP is calculated as follows;
[tex]NPP = GPP - R[/tex]
Substitute values for GPP and R
[tex]NPP = 7\ kcal/m^2/yr - 3\ kcal/m^2/yr[/tex]
[tex]NPP = 4\ kcal/m^2/yr[/tex]
Hence, the Net Primary Productivity is [tex]4\ kcal/m^2/yr[/tex]

A sailboat moving southward through the water experiences a force of 2500 newtons exerted by the wind on its sail. The water and air resistance apply a force of 1500 newtons in the opposite direction of the sailboat's direction of travel
Answer:
The sailboat moves southward at a force of 1000 Newton
Explanation:
The sailboat is moving south at 2500 newtons. The opposite force is only 1500 newtons, which is less than 2500 units. The greater force cancels out the lesser force. In order for the boat to be stopped or pushed back, the water and air resistance would of had to of been greater than or equal to 2500 Newtons. Because of this opposite force, the boat continues to move but with a lesser amount of force. You can use subtraction to find the remaining force the boat has.
2500 Newtons - 1500 Newtons = 1000 Newtons
How many solutions exist for the given equation? 3x + 13 = 3(x + 6) + 1
Answer:
There is no solutions to this problem.
Because when you solve it you get an untrue statement. When this happens, it means that there is nothing that can make it true.

Explanation:
PLZ HELP as a result of the change in the migratory pattern, the two groups of blackcaps(those that migrate to England vs those that migrate to spain) have different mating seasons. Blackcaps that migrate to England have an earlier mating season. Scientists believe that this difference may result to two different species of birds. This shows: a) the effects of symbiosis b)the effects of local evolution or migration on an ecosystem c) the difference between biotic factors in an ecosystem d) how migratory patterns change in response to alterations in an ecosystem
Answer:
b) the effects of local evolution or migration on an exosystem
Explanation:
a) false; symbiosis is the relationship between two species with either a mutual benefit to both creatures, one benefiting and the other remaining neutral, or one being negatively affected while the other benefits. There is no relationship between the two groups of blackcaps to a is false.
b) true; the effects of local evolution or migration on an ecosystem. Local evolution has not occured yet but migration has. The effect that scientists believe may happen to the ecosystem because of the migration is the creation of a new species, which would definitely effect an ecosystem
c) false; biotic factors are the living parts of an environment, such as plants, animals, and insects. The difference in the two groups of blackcaps isn't what biotic factors they use but when their mating season is. Biotic factors have no effect whatsover.
d) false; there are no given alterations in the ecosystem. Migration patterns do not just change because of something as small as a shift in bug population. Migration habits are largely genetic, such as is the case of monarch butterflys migrating from north to south and back across the continent. If a group of blackcaps are migrating somewhere different, it has been ocurring for a while, so it isn't fault of the ecosystem that suddenly made blackcaps switch migration course.
Answer: D how migratory patterns change in response to alterations in an ecosystem

5. What were Europeans’ motivations for exploring and settling the Americas, and why did competition increase during the 1500s and 1600s?
Answer:
The main motivations why the European powers (mainly Spain, Portugal, France and Great Britain) began to explore and occupy the American continent were the amount of valuable natural resources that were in the continent, such as gold, silver, food, etc., which could be used by European nations to enhance their mercantilist economies.
In addition, it was a time and a political context in which the greatness and power of nations is mediated according to their territorial extension. Thus, a huge continent like America gave these nations the possibility of expanding their dominions, controlling the seas and politically surpassing their adversaries.
It was precisely for these reasons that a century after the discovery of America, competition between nations increased, with the arrival of other nations such as the Netherlands or Russia, which also tried to establish colonies and obtain their share in the territorial and economic distribution of the continent.

i am doing a rhetorical device project for ap lang and i’m having trouble trying to answer this question:
how does this example from barack obama’s 2004 dnc speech shown to be an effective use of climax (the rhetorical device, not the plot of a story)?
if you need a definition of climax, it is a rhetorical device in which words, phrases, or clauses are arranged in order of increasing importance.
Answer:
Well, the passage starts out with using words that are increasingly more and more intense. We first begin with the use of the word "solemn", which is relatively peaceful, laid back, and not exactly very provoking. then next we get the phrase "shade the truth" which provokes question in the reader... of implying something isn't completely represented. Then we have a long explanation why, further drawing in the reader into this conflict, discussing the families and the soldiers (emotional element!!) and then it finally hits the climax: to earn the respect, a very hard hitting sentence.
in short, this phrase slowly draws in the reader of the importance of taking care of these nations troops.
