-Does it make sense for a company's first month of operation to have: negative operation activities, investing activities and positive financing activities? why?

-The same company has an EPS of 0.2, what does that mean for the company's performance?

5) Fill in the blanks in the table below. Assume that the MPC is constant over everyone in the economy.

Given:

E[x] = 4, E[y] = 6, Var(x) = 2, Var(y) = 1, and cov(x,y) = 0.2

Find a lower bound on (5 < x + y < 10). State the theorem used.

Calculate the appropriate amount of 28 wt% aqueous NH3 and solid NH4Cl to be mixed together to yield 500 ml of a ~0.2 M pH 10 buffer. Check with pH paper. Store in a flask and adjust pH as needed.

Nursing considerations for doxorubicin include:

1. Determine the ROC for stability for transfer function H(s) = 1 / (s-2) ( s-1)

2. Determine the ROC for stability for transfer function H(z) = (z-1) / (z+0.1) (z-0.2)

Suppose you work for an insurance company. You know that there are equal numbers of individuals who will get in an accident with probability 0.2 and 0.3 and that the loss from getting in an accident is $4,000. Suppose you wish to screen individuals by offering full- coverage insurance as well as 30 percent coinsurance (i.e., the insurance pays 30 percent of the loss amount, or $1,200, in the event of an accident). You wish to include a 5 percent premium over the actuarially fair values for these policies to help cover overhead and pro- vide a profit margin for your company.

Will this pair of policies screen individuals into risk classes if we assume that all insuredindividuals have utility function U(X) ? 2000 · (X/4000)0.5 where X is income? Hint: Calculate utility (or expected utility) for each of the three options (no insurance, full- coverage insurance, and coinsurance) for both types of individuals and compare ex- pected utility levels to see what each will choose.

Background on Expected Utility: In this conceptualization of utility, we can compare uncertain outcomes with certain outcomes. For example, if an individual does not have insurance and does not get into an accident, he or she has a utility level of 2,000 (because X ? $4,000) or zero if he or she gets into an accident (because then X ? $0). The expected utility (EU) is based on the likelihood of each event occurring. A per- son facing a 10 percent chance of having an accident would have an expected utility of 1,800 using this utility function because EU ? 0.9 · 2,000 ? 0.1 · 0. This person would be indifferent between facing this “lottery” and having $3,240 with certainty (because U(3240) ? 1,800). This certainty equivalent value was obtained by solving for X in the equation 1800 ? 2000 · (X/4000)0.5. The lottery would be preferred to amounts less than $3,240 offered with certainty.

The next two questions refer to the following physical situation:

Two blocks (masses m₁ = 30 kg and m₂ = 7 kg) sit atop one another as shown below. The coefficient of static friction between the blocks is μ_s= 0.32.  There is no friction between the lower block and the surface on which it rests. A constant external force F is applied to the lower block.

What is F_max, the maximum magnitude of this force such that the upper block does not slide with respect to the lower block?

If there is kinetic friction between the lower block and the surface, the magnitude of the maximum possible force F_max that can be exerted on the lower block before the upper block starts sliding with respect to the lower block...

A precocious child wants to determine the moment of inertia, I_o, of the local merry-go-round. The child measures the radius of the merry-go-round (R = 2 m), then weighs herself (m = 25 kg), then notices that when she moves from the center of the merry-go-round to the rim, the rotational velocity of the merry-go-round changes from 0.3 rev/sec to 0.2 rev/sec. If the child treats herself as a point mass, what moment of inertia does she estimate for the merry-go-round?

As the child moves from the center of the merry-go-round to the rim, the kinetic energy of the child plus the merry-go-round...
