Answer:
Invest at a minimum of 7.5% annual simple interest
Explanation:
Given the goal of purchasing a boat that will cost $30,000 in 20 years, David needs to earn an interest computed below on his investment in the savings account.
Interest required = 30,000 - 12,000
= 18,000
Therefore the minimum rate of interest that will achieve this goal,
= Principal * rate * time = target amount
= 12,000 * R * 20 years = 18,000
= R = 18,000/(12,000*20) = 0.075 = 7.5%.
In addition, David could also continue his saving from his teaching job. This will reduce the minimum investment return required to achieve the goal.
The still-face interaction paradigm
<span>An experimental task was introduced in 1978 to prove that infants actively contribute to social interaction. It is called the Still-Face Paradigm or SFP.</span>
<span>In the experiment, 3 phases of face-to-face interaction of infants with an adult were tested: the normal interaction, the still-face (where the adult becomes unresponsive and maintains a neutral facial expression), and a reunion where the adult resumes normal interaction.</span>
<span>Indeed, the still-face paradigm showed effects like increased gaze aversion and less smiling. </span>
Answer:
d.efficient in production but not necessarily in allocation.
Explanation:
The production possibility curve portrays the cost of society's choice between two different goods. An economy that operates at the frontier has the highest standard of living it can achieve, as it is producing as much as it can using the same resources. If the amount produced is inside the curve, then all of the resources are not being used.
- all points on the curve are points of maximum productive efficiency
- However, an economy may achieve productive efficiency without necessarily being allocatively efficient. Market failure (such as imperfect competition or externalities) and some institutions of social decision-making (such as government and tradition) may lead to the wrong combination of goods being produced (hence the wrong mix of resources being allocated between producing the two goods) compared to what consumers would prefer, given what is feasible on the PPF.
