Answer:
The fixture, is the right answer.
Explanation:
The “fixture” is the correct answer because the term fixture refers to the piece of equipment or furniture that is fixed in the house or stays at a fixed position in the building. For example, there are many things in the house that are used only at its fixed position like the AC in the room. Once the AC is installed in the room then it is stationary, no one gonna move it from its original place. Likewise in the question, it is about the ceiling fan and the fan is also stationary as it stays at a fix position.
Answer:
The correct answer is A. The Lorenz Curve is a curve that shows the percentage of total household incomes received successively larger fractions of the population, starting with the poorest group.
Explanation:
The Lorenz curve represents the relationship between the cumulative percentage of the population size and the cumulative percentage of the income of the same population.
A Lorenz curve is a graph in which income is cumulatively plotted against the population. A given point on the vertical axis represents the sum of all incomes up to a certain level. The point on the curve to the right of it corresponds to the number of people who have an income up to that level.
The curve always runs lower, which means that at any given point on the curve, the percentage of total national income is lower than the percentage of people who have an income up to that level. On such a curve we can read, for example, that 25% of the income collectors together own 8% of the total income.
Answer:
According to the sticky-wage theory, the economy is in a recession because the price level has declined so that real wages are too high, thus labor demand is too low.
According to the sticky-price theory, the economy is in a recession because not all prices adjust quickly.
According to the misperceptions theory, the economy is in a recession when the price level is below what is expected.
Explanation:
The above mentioned are the three theories of the upward slope of the short-run aggregate-supply curve.
To raise money to grow the company
Answer:
They should operate Mine 1 for 1 hour and Mine 2 for 3 hours to meet the contractual obligations and minimize cost.
Explanation:
The formulation of the linear programming is:
Objective function:
Restrictions:
- High-grade ore: 
- Medium-grade ore: 
- Low-grade ore: 
- No negative hours: 
We start graphing the restrictions in a M1-M2 plane.
In the figure attached, we have the feasible region, where all the restrictions are validated, and the four points of intersection of 2 restrictions.
In one of this four points lies the minimum cost.
Graphically, we can graph the cost function over this feasible region, with different cost levels. When the line cost intersects one of the four points with the lowest level of cost, this is the optimum combination.
(NOTE: it is best to start with a low guessing of the cost and going up until it reaches one point in the feasible region).
The solution is for the point (M1=1, M2=3), with a cost of C=$680.
The cost function graph is attached.
