A study was conducted on the effects of long-term marriage (more than 10 years).
Researchers gathered data from a random sample of 4,563 adults and measured
quite a few variables, in addition to the explanatory variable of marriage and the
response variable of longer life span. According to a newspaper article summarizing
the study, those in long-term marriages were more likely to be more physically
active, at a healthy weight, and nonsmokers. Those who were not married were
about 20% more likely to be deceased. What conclusion can we draw from this
study? Explain.
D We can infer a cause-and-effect relationship because the sample was selected
randomly.
We cannot infer a cause-and-effect relationship because treatments were not
assigned randomly.

Which class is the best one to take? Also could you please explain why you chose the one that you did?
1. AP Euro
2. AP Psych
3. AP World

Answers

Answer:

AP Psych

Explanation:

In my opinion, it will take you farther in college than AP Euro or World would. You'll be suprised to find how many majors require Psychology. First, it is both a social science and biological science. If you are taking, AP bio/AP chemistry or any other science AP psych is the way to go. You go over neurotransmitters and their major functions and how relate to our behavior. I would also take this class if you have previously taken AP biology/chemistry because you will begin the class already knowing about neurotransmitters, inhibitors, and receptors. I took AP bio last year and am taking AP Psych this year and I currently have an A because I am educated on neurological functions. Even if you haven't taken bio or chemistry I would still highly suggest psychology because it prepares you for college and enhances your understanding of society and your own emotions.

In a class of students, the following data table summarizes how many students play an instrument or a sport. What is the probability that a student chosen randomly from the class does not play a sport?
Plays an instrument Does not play an instrument
Plays a sport 8 7
Does not play a sport 3 12

Answers

Answer:

79.31%

First we need to find the total number of students.

We do that summing all the four values in the table:

Total students = 2 + 18 + 3 + 6 = 29

Then, the students that play a sport or an instrument are all student but the ones that don't play both:

Students(sport or instrument) = 29 - 6 = 23

So the probability of a random student playing a sport or an instrument is 23/29 = 0.7931 = 79.31%

About what proportion of the variation of wages across workers is explained by factors that can be
measured? What are the other factors that explain wage differences but are difficult to measure?

Answers

Explanation:

Easy Measuring of the wages could be from data collected such as from the International Labour Organization. They compare wages from state-to-state, country-to-country and from men-to-women in the workplace.

Hard factors explaining wage differences come from classical economic theory (standard) and labour market imperfections due to varying circumstances from country to country. This is largely due to the differing economic standards and regulations that are ran by different countries

Simple Estimating of the wages could be from information gathered, for example, from the International Labor Organization. They contrast compensation from state-with state, country-to-country and from men-to-ladies in the working environment.

What does International Labor Organization means?

The International Labor Organization (ILO) is a Unified Countries office whose command is to propel social and monetary equity through setting international labor norms.

The ILO's labor guidelines are pointed toward guaranteeing available, useful, and manageable work overall in states of opportunity, value, security and respect.

They are gone ahead in 189 shows and arrangements, of which eight are delegated key as per the 1998 Statement on Central Standards and Privileges at Work; together they safeguard opportunity of affiliation and the powerful acknowledgment of the right to aggregate dealing, the end of constrained or necessary labor, the nullification of kid labor, and the end of segregation in regard of business and occupation.

Therefore The ILO is a significant supporter of international labor regulation.

Spray irrigation is used because it allows water to reach the common soil with less impact, without stimulating soil compaction. In addition, this irrigation method promotes better water distribution, irrigation control, optimization of water volume, reduction of waste and better use of water by the plant.

Ebecca reads a book at a rate of 1 page every 4 minutes. If her reading rate remains the same, which method could be used to determine the number of minutes for her to read 16 pages. Group of answer choices add 4 and 16 divide 16 by 4 multiply 4 by 16 subtract 4 from 16.

Answers

Answer:

Multiply 4 by 16

Explanation:

Given

[tex]Rate = 1\ page/4\ minutes[/tex]

Required

Select the method that maintains her rate for 16 pages

To get the method for 16 pages, we simply multiply 4 by 16. This is shown below

[tex]Rate = 1\ page/4\ minutes[/tex]

Calculate the unit rate

[tex]Rate = \frac{1}{4} page/min[/tex]

[tex]Rate = 0.25 page/min[/tex]

For 16 pages, it is:

[tex]Rate = \frac{16 page}{4 min * 4}[/tex]

[tex]Rate = \frac{16 page}{4 min * 16}[/tex] -- Here, we multiply 4 by 16

[tex]Rate = \frac{16 page}{64\ min}[/tex]

[tex]Rate = \frac{16}{64} page/min[/tex]

[tex]Rate = 0.25 page/min[/tex]

See that the unit rates remain the same.

Other options will give different rates

Warmer temperatures at the Earth's poles could change atmospheric circulation and wind patterns. Propose a solution for how communities near the poles can prepare for these changes in wind.

Answers

The answer is in the question, warmer temperatures at the earths poles could change atmospheric circulation and wind patterns.

Warmer temperatures at the poles could alter wind patterns and atmospheric circulation.

What is atmospheric circulation?

Through atmospheric circulation, heat is transferred over the surface of the Earth. This has an effect on the water cycle, including cloud formation and precipitation events. The movement of air masses determines our everyday weather, and long-term patterns in circulation have an impact on regional climate and ecosystems.

This pattern, called atmospheric circulation, is a result of the Earth being heated by the Sun more at the equator than in the poles. The rotation of the Earth has an effect on it as well. In the tropics, near the equator, warm air rises.

Atmospheric circulation, or the movement of heat and air over the earth's surface, is governed by Hadley, Ferrel, and polar cells.

Thus, Warmer temperatures at the poles could alter wind patterns.
