Dr. Adams is studying how the quality of breakfast influences academic performance for elementary school children. A sample of 100 children is selected. Fifty children are provided with a nutritious breakfast when they arrive at school each morning. The other 50 children are given a doughnut each morning. After three months, Dr. Adams records the academic achievement level for each child and compares the two groups of scores. In this example, there are __________ levels of the independent variable, and __________ dependent variable(s). Group of answer choices

Answers

Answer 1

Answer:

2 levels of the independent variable and 0 levels of dependent variable

Explanation:

Levels of independent variable indicate the types of experiment here. Here we have the control experiment and experimental group. The control experiment/group is the group that is not altered and used to measure the experimental group. The control group is the 50 children that took nutritious breakfast while the experimental group is the 50 children that took doughnuts /non nutritious food. If there are more than two types of experiment, the number of experiment types are the number of levels of the independent variable. The dependent variable here has 0 levels

Predict whether carbon dioxide or water would have a higher boiling point. explain your predicament in terms of attractions between molecules.

Answers

Answer:

Explain your prediction in terms of the attractions between molecules. I would predict that since ionic bonds, bonds that are charged, have very high boiling points, then the water would have a higher boiling point because it has a slight charge whereas carbon dioxide is stable.

Explanation:

Water will have a higher boiling point than Carbon dioxide. The reason for this can be ascribed to the fact that the molecules in water share dipole-dipole interactions. These are stronger than the Van der Waals forces that hold the elements in carbon dioxide together.

Before compounds can attain their boiling points, the forces that hold them together will have to be overcome. The stronger the forces, the higher the boiling points.

Since water has a polar, covalent, intramolecular bond that is stronger than the weak Van der Waal's forces, more time and force will need to be put in before it attains its boiling point.

So, water will have a higher boiling point compared to carbon dioxide.

Yes, this is at the very basis of creativity. To always look for different and innovative ways to do anything. It doesn't matter if is homework, a final project, or house activity.

What is the third step taken when checking a student's reading rate?

reading out loud with a timer set
counting the number of words read
practicing elements of fluency

Answers

Answer:

practicing elements of fluency

Explanation:

Practicing elements of fluency is the third step taken when checking a student's reading rate. Hence, option D is correct.

What is checking a student's reading rate?

Your reading speed is typically measured in words per minute (WPM). It is estimated by keeping track of how many minutes you spend reading a text and dividing that number by the number of words in the text. You can use a timer to measure that value yourself, but using our free tool we created for you is simpler.

The total number of words read in a minute is divided by the number of errors to determine reading fluency. Per word, just one error is counted. This provides the words that are right per minute (wpm). Students' degrees of fluency are indicated by words correctly said per minute.

Thus, option D is correct.

Answer:

problem-focused coping strategy

Explanation:

In psychology, Folkman and Lazarus have proposed two different kinds of coping strategies in 1984 including the problem-focused and emotion-focused coping strategies.

In the "problem-focused coping strategy", an individual tries to make various attempts in order to manage or deal with the problems that are causing him or her to experience stress (the things that are responsible for causing stress is referred to as the stressor). The problem-focused coping technique is often used in coping day-to-day problems by identifying a specific problem, thinking of possible solutions, considering costs & benefits associated with the solutions, and at last selecting the best alternative to resolve the problem.

In the question above, the given statement represents "problem-focused coping".

Answers

Answer:

Primates that show ecological adaptations similar to those presented by humans and great primates such as chimpanzees and gorillas that are genetically similar to humans.

Explanation:

Primatology is the science that studies the entire order of primates, from their ancestral forms to the most modern forms that you can see today. In addition to studying the behavior and biological and evolutionary conditions of these animals, these scientists seek to associate the information found with the study of some primates to explain elements of human beings. In this case, the most relevant primates are monkeys and terrestrial primates because they have biological adaptations similar to those presented by humans; and, great primates that have a strong genetic similarity to humans, such as chimpanzees and gorillas.

Which type of interest rate includes the impact of inflation?
O nominal interest rate
O compounding interest rate
Oreal interest rate
O simple interest rate

Answers

Answer: C. Real interest rate

Explanation:

I just took the test, and i got it right :)

Can I get the brainliest answer pls?

The type of interest rate that includes the impact of inflation is the real interest rate. Hence option C is correct.

The real interest rate is adjusted for inflation and represents the rate of return on an investment after accounting for changes in purchasing power due to inflation. It reflects the true growth in the value of an investment by considering both the nominal interest rate and the inflation rate.

The nominal interest rate, on the other hand, is the stated interest rate without adjusting for inflation. It represents the raw return on an investment or the cost of borrowing, but it does not account for changes in the purchasing power of money over time.

The real interest rate is considered a more accurate measure of the actual return on investment because it takes into account the erosion of purchasing power caused by inflation. It allows investors to assess the true value and potential growth of their investments by factoring in the inflation rate.

Therefore option C is correct.

In at least one hundred and fifty words, compare and contrast the philosophies of constitutionalism and the divine right of kings. Which had the greatest impact on the formation of the U.S. Constitution?

Answers

Answer:

Constitutionalism refers to a political structure of a state based on the constitution, as the name itself says. A constitution is the most important legal document in a country, listing the rules and laws that everyone, be it regular people, institutions, or the president himself has to follow. Constitutionalism was created to make people equal, to protect their natural rights and guarantee them liberty in the country they live in.

On the other hand we have the divine right of kings. It is a concept which is quite opposite to that of constitutionalism. As the name itself says, the divine right of kings assumes that king was sent to earth to rule instead of God himself. Given that God doesn't have a physical presence in our world, he has chosen kings to be his representatives on Earth. Thus, the king has every right to do whatever he pleases, without having to think about constitutions, governments, or the feelings of his subjects.

I believe that America is based on the principles of constitutionalism, mostly because it never had a king, but was rather a democratic republic from the very beginning.

Answers

Answer:

D “You are giving others better rates than you are us,” said Mr. Alexander, the representative of  the firm. “We cannot compete if you do that.”

Explanation:

The progressives reformation was a movement that gained ground between the 1890s to the 1920s in the United States of America. At that time wealthy businessmen made their monies through corrupt practices and oppression of the poor laborers. Most times, the government supported them when given bribes.

The progressives were against this. In the excerpt, it was clear that the government official was giving some companies better rates than the others and that was why Mr. Alexander went to confront them. This excerpt best supports the argument of progressives regarding the relationship between government and business.
