Afishing company operates a search plane to find schools of fish in the ocean. schools of fish are randomly located in the ocean. on average, there is one school of fish per 100,000 square miles of ocean. during any one day, the plane can search 10,000 square miles. 1. what is the expected number of schools of fish found in one day of searching? a. 3 b. 1 c. 0.3 d. 0.1 2. what is the probability of finding at least one school of fish in one day of searching? a. 0.0905 b. 0.0952 c. 0.2592 d. 0.9502

Acommon procedure for measuring the velocity of an airstream involves the insertion of an electrically heated wire (called a hot-wire anemometer) into the airflow, with the axis of the wire oriented perpendicular to the flow direction. the electrical energy dissipated in the wire is assumed to be transferred to the air by forced convection. hence, for a prescribed electrical power, the temperature of the wire depends on the convection coefficient, which, in turn, depends on the velocity of the air. consider a wire of length l = 20 mm and diameter d = 0.5 mm, for which a calibration of the form v = 6.25 ă— 10â’5 h2 has been determined. the velocity v and the convection coefficient h have units of m/s and w/m2 â‹… k, respectively. in an application involving air at a temperature of tâž = 25â°c, the surface temperature of the anemometer is maintained at ts = 75â°c with a voltage drop of 5 v and an electric current of 0.1 a. what is the velocity of the air?
