Air quality is of concern to everyone. One measure is the number of micrograms of particulate present per cubic meter of air. In a small city in South Dakota, data was obtained for five randomly selected 24-hour periods during June. These readings are:                                                                                                   (15 points)

45,          50,          62,          57,          70

1. Calculate an interval for which you have a high degree of confidence that at least 95% of all 24-hour periods will have readings between the limits of the interval.

The Asian financial crisis of 1997-98 began with currency speculators dumping the overvalued Thai baht that eventually led to its devaluation. Sensing that other Asian economies were also weak, speculators targeted them as well which led to the crisis spreading to Malaysia, Indonesia, the Philippines and South Korea. Initial Post Instructions What do you think are the main causes of this crisis? Are there factors that are critical in any explanation and which may indicate that a crisis is imminent?

Globization prospectus on avocados. Exported from Mexico and imported to USA.

Where is the food produced now? How much does it cost in USD? Which countries consume the item? Where are the respective countries located (e.g., in the global North/South)? Why is a country’s location significant? Who benefits from the import/export of the food? Who is most harmed? How has the import/export of the food affected different groups/local communities in each of the countries?

“Even though price controls fail to protect many consumers’ controls hold the promise of protecting groups that are particularly hard-pressed to meet price economies”. 1.1. In terms of the above statement, discuss the two (2) main types of price controls that can be implemented by government in your country. Substantiate your answer with the aid of diagrams. (20)

1.2. Explain the role of the National Energy Regulatory Authority in South Africa (NERSA) in terms of prices controls. (10)

Distinguish between demand-pull inflation and cost-push inflation and then use an AD-AS (aggregate demand/aggregate supply) model to illustrate the theoretical effects of these two types of inflation on the price level (P), employment (L) and economic growth (real GDP) in the short run. Now identify the various factors that have contributed towards demand-pull inflation and cost-push inflation in South Africa and critically analyse whether they are consistent with the predictions of the AD-AS model.

Two vehicles are approaching an intersection. One is a 2300 kg pickup traveling at 13.0 m/s from east to west (the ?x- direction), and the other is a 1300 kg sedan going from south to north (the +y?direction at 21.0 m/s ).

The route followed by a hiker consists of three displacement vectors , , and . Vector is along a measured trail and is 1360 m in a direction 16.0 ° north of east. Vector is not along a measured trail, but the hiker uses a compass and knows that the direction is 27.0 ° east of south. Similarly, the direction of vector is 15.0 ° north of west. The hiker ends up back where she started, so the resultant displacement is zero, or + + = 0. Find the magnitudes of (a) vector b and (b) vector c
