An experiment is designed to test the potency of a drug on 20 rats. Previous animal studies have shown that a 10-mg dose is lethal 5% of the time within the first 4 hours; of the animals alive at 4 hours, 10% will die in the next 4 hours. (This is a 3 part problem)a) What is the probability that 3 or more rats will die in the first 4 hours?b) What is the probability that 0 rats will die in the 8 hour period?c) What is the probability that 2 rats will die in the 8 hour period?

Would you expect the price elasticity of demand to be higher

Would you expect the price elasticity of demand to be higher at the level of an individual school or at the aggregate level (e.g., all 4-year colleges and universities)? Why? Despite the empirical evidence to the contrary, college decision-makers often believe that their price elasticity of demand is essentially zero. Is that right? How important were price considerations in making your college decision? Would a change of a few thousand dollars have mattered? Would you expect the price elasticity of demand to be higher for financial-aid students or for non-aid students? Why? How does a students income elasticity affect the demand for higher education at College?

QUESTION 1 A small 12.00 g plastic ball is suspended by a string in a uniform, horizontal electric field. If the ball is in equilibrium when the string makes a 30 angle with the vertical, what is the net charge on the ball? Q = C QUESTION 2 Two charges q1 and q2 have a total charge of 10 C. When they are separated by 3 m, the force exerted by one charge on the other has a magnitude of 8 mN. Find q1 and q2 if (a) both are positive so that they repel each other, and q1 is the smaller of the two. (For the universal constant k use the value 8.99 109 N m2/C2. Attachments: PHYS-HW2.docx

1. The summer beach house rental season is June through early September; what will happen to the price and quantity of beach house rentals in New Jersey during the summer season compared to the off-season? Is there a movement or a shift, why? Graph and explain the relationship. 2. Show graphically and explain in writing how the following demand and supply curves are likely to shift in response to the indicated changes: a) The price of large screen LCD and plasma TVs are going down. Why? b) The effect on the demand curve for hybrid cars (run on electric and gas and get much greater gas mileage) vs. regular cars (run only on gas) when the price of gas doubles. You need two graphs. First, graph the supply and ddemand curves then show the changes in a and b above regarding quantity and price. 3. The price of houses has been going down for a few years. Graphically show and then explain what has occurred and why (reason for shift)? You can make up a reason as well as long as you support it. Attachments: Macroeconomic….docx
