An evil king has n bottles of wine, and a spy has just poisoned one of them. unfortunately, they do not know which one it is. the poison is very deadly; just one drop diluted even a billion to one will still kill. even so, it takes a full month for the poison to take effect. design a scheme for determining exactly which one of the wine bottles was poisoned in just one month's time while expending o(log n) taste testers.

When used-car dealers signal the quality of a used car with a warranty, a. buyers believe the signal because the cost of a false signal is high b. it is not rational to believe the signal because some used-car dealers are crooked c. the demand for lemons is eliminated d. the price of a lemon rises above the price of a good used car because warranty costs on lemons are greater than warranty costs on good used cars

Acompany has two products: standard and deluxe. the company expects to produce 36,375 standard units and 62,240 deluxe units. it uses activity-based costing and has prepared the following analysis showing budgeted cost and cost driver activity for each of its three activity cost pools.budgeted activity of cost driver activity cost pool budgeted cost standard deluxe activity 1 $ 93,000 2,500 5,250 activity 2 $ 92,000 4,500 5,500 activity 3 $ 87,000 3,000 2,800 what is the overhead cost per unit for the standard units? what is the overhead cost per unit for the deluxe units?

The monthly demand equation for an electric utility company is estimated to be p equals 60 minus left parenthesis 10 superscript negative 5 baseline right parenthesis x, where p is measured in dollars and x is measured in thousands of killowatt-hours. the utility has fixed costs of $3 comma 000 comma 000 per month and variable costs of $32 per 1000 kilowatt-hours of electricity generated, so the cost function is upper c left parenthesis x right parenthesis equals 3 times 10 superscript 6 baseline plus 32 x. (a) find the value of x and the corresponding price for 1000 kilowatt-hours that maximize the utility's profit. (b) suppose that the rising fuel costs increase the utility's variable costs from $32 to $38, so its new cost function is upper c 1 left parenthesis x right parenthesis equals 3 times 10 superscript 6 baseline plus 38 x. should the utility pass all this increase of $6 per thousand kilowatt-hours on to the consumers?
