Because of your excellent economics background, you have been hired as a consultant to evaluate the operations of King Tutelage, a local non-profit organization that tutors lowincome school children. To provide services, the group uses two types of workers: professional staff and untrained volunteers. Because they are in such high demand, the professional staff must be paid the going wage rate of $25/hour for their services. While the volunteers are not paid, there is a cost to hiring them, since they need training and supervision. King Tutelage has found that they typically spend about $10/hour for the services provided by volunteers.

While professional staff members are more expensive, they are also more productive. Based on the current employment levels, you find that the marginal product of a professional staff member is 5 (that is, 5 children per hour can be helped). In contrast, the marginal product of a volunteer is 1 (that is, only one child per hour can be helped). Given this information, is King Tutelage making the most efficient use of their resources? Have they hired the appropriate number of each type of worker? If so, how did you determine this? If not, what recommendations can you make to improve their efficiency? (6 points in total)

You became president of a small nonprofit theater company. Your playhouse has 120 seats and a small stage. The actors have national reputations, and demand for tickets is enormous relative to the number of seats available; every performance is sold out months in advance. You are elected because you have demonstrated an ability to raise funds successfully. Describe some of the decisions that you must make in the short run. What might you consider to be your “fixed factor”? What alternative decisions might you be able to make in the long run? Explain in 1 to 3 pages Clearly explain the factors of consider as your “Fixed Factor” and alternative short term and long term decisions.

Complete 2 page APA formatted essay: Natural and houman life in Mono Lake.

While many species find the lake unfavorable for life due to its high pH and alkalinity, the alkali flies find a lot of benefit in these conditions (Herbst1& Bradley1 670). The water of the lake provides a natural breeding ground to the flies much as it provides good ground for feeding as it is filled with different kinds of algae. blue and green (Herbst1& Bradley1 670).

Many species of birds live around Mono Lake and many others travel from as far as South America and take time to rest and rejuvenate on as they migrate from different places. The birds mostly find the Mono Lake a suitable ground for breeding as there is plentiful supply of food in the form of alkali flies and brine shrimps, especially between mid summer and fall (Cash & Bradley 312). It is estimated that over 100 bird species in totaling millions grace the Mono lake area at different times of the year (Mono Basin Ecosystem Study Committee of the National Research Council 46). It is estimated that more than 44,000 California Gulls find breeding ground around the lake in spring every year (Mono Basin Ecosystem Study Committee of the National Research Council 46). Some of the birds that are found in the wider Mono Lake region include red-necked phalaropes, flamingoes, egrets, Wilsons phalaropes, horned lark , bank swallow, dusky flycatcher, stellers jay, scrub jay and eared grebes, to name but a few. While the population of water fowls such as ducks was high in the lake several decades ago, this is no longer the case. The ducks, Gadwalls, Geese, Mallards,and Green-winged Teals have almost disappeared over the years as a consequence of the diversion of the river that flowed into the lake in 1941.

Humans have lived in the Mono Lake region for a long time. The Kutzadikaa people find benefit from the lake in that they normally hunt alkali flies for food during winter periods as noted by Herbst and Bradley (193). For the different bird species and the tufa mounds that

Consider a linear regression model with p parameters,fit by leastsquares to a set of training data (x1; y1); : : : ; (xN; yN) drawn at randomfrom a population. Let B be the least squares estimate. Suppose wehave some test data (~x1; ~y1); : : : ; (~xM; ~yM) drawn at random from thesame population as the training data. If Rtr(B) = 1NPN1 (yi – BT xi)2and Rte(B) = 1MPM1 (~yi ô€€€ T ~xi)2, prove thatE[Rtr( ^ )] E[Rte( ^ )];where the expectations are over all that is random in each expression.
