Fire in energized electric equipment is designated as 'Class C' class of fire.The nonconductive extinguishers agents used can be CO2 , dry powder (chemical) and fire suppression agent NOVEC 1230 can also be used.The reason for such energized electric equipment Class C fire may start from overloading of electrical equipment or short circuit in circuitry . Water based agents should never be used to suppress this Class C fire in electric equipments, since water will conduct current and can give electric shock to the person operating to suppress the fire. When such electric energised fires occur try to disconnect electric connection to the equipment along with suppression of the fire.

2. Suppose a fire insurance company wants to relate the amount of fire damage in major residential fires to the distance between the burning house and the nearest fire station. A random sample of 15 fires in a large suburb is selected. The amount of damage (thousands of dollars) and the distance (miles) between the fire and the nearest fire station are recorded for each fire. The following simple linear regression model was used: Fire Damagei=B0+B1(Distance from Fire Station)i+Ei Coefficients...

Problem 2. (Impatient consumers) Consider an economy where agents live for two periods. There are two types of agents A and B. Both types of agents are impatient, so value of consumption in period 2 is less than value of consumption in period 1. Their preferences are described by the utility function where 0< 81 ( being less than 1 reflects impatience). Type A's endowment pattern is (n,ni)-(EAN) where Ea > 0. Type B's endowment pattern is u'of)- (0, Ep)...
