The marginal cost is how much it costs to produce one item more. It cost 0$ to produce 0 bikes but if you make one, then it costs 80$. Hence the marginal cost for the first bike is 80$. For the fourth bike, we have that the 3 bikes cost 110$ and the 4 bikes cost 130$. Hence it costs 20$ dollars to produce one more bike (from 3rd to 4th) and hence the marginal cost is 20$. Similarly for the 6th bike, we compare the cost of producing 5 bikes to the cost of producing 6 bikes and we get that the marginal cost is 50$. Applying the same methodology, the marginal cost for the 7th bike is 60$.
Today, a majority of the world’s population<span> lives in cities</span>. By 2050, two-thirds of all people on the planet are projected to call urbanized areas their home. This trend will be most prominent in developing countries in Africa, Asia and Latin America: More than 90% of the global urban growth is taking place in these regions, adding 70 million new residents to urban areas every year.
For the many poor in developing countries, cities embody the hope for a better and more prosperous life. The inflow of poor rural residents into cities has created hubs of urban poverty. One-third of the urban population in developing countries<span> resides in slum conditions</span>. On the other hand, urban areas are engines of economic success. The 750 biggest cities on the planet account for 57% of today’s GDP, and this share is projected to rise further. It is thus unsurprising that rapid urban growth has been dubbed one of the biggest challenges by skeptics and one of the biggest opportunities by optimists.
One reason for this disagreement is that the relationship between economic development and urbanization is complex; causation runs in both directions. In the study “Growing through Cities in Developing Countries,” published in the World Bank Research Observer, Gilles Duranton from the University of Pennsylvania examines this relationship in depth. The strong positive correlation between the degree of urbanization of a country and its per-capita income has long been recognized. Still, the relationship between these two variables is only partially understood in the context of developing countries. In reviewing studies that focus on the impact of cities both in developed and developing countries, Duranton tries to identify the extent to which urbanization affects economic growth and development. (“Agglomeration” economies refers to physical clustering.
external <span>locus of control is the belief that our outcomes are outside of our control; internal locus of control is the belief that we control our own outcomes.
People that excel in external locus control will tend to be more spiritual are not suited in the decision-making process because they generally could accpet their 'fate'. Meanwhile, people that excel in internal locus control tend to be logical and ambitious with a strong drive to improve themselvess.</span>
Answer:
what was memorized was the idea of "light" as a description of weight, not "light" as illumination
Explanation:
When the research participant memorized the words “heavy – light” his brain associated with the words “light” unicament in the sense of weight. In this context, the participant's brain disassociated the word from any meaning other than that previously associated. Thus, when faced with the word "light" written with the sense of luminosity, the participant's brain did not allow the participant to remember that he had seen this word before.
Answer:A self-report inventory
Explanation:A self-report inventory is psychological test which gives someone a survey or questions in form of a questionnaire which they need to fill with or without the help of a researcher. Self report inventory works with asking direct question which ask someone about their values , interests and personality types.
