Based on information in Deep River Jim’s Wilderness Trail Book, the rate at which crickets chirp varies linearly with the temperature. At 59o F., they make 76 chirps per minute, and at 65o F., they make 100 chirps per minute. a) Is this a linear or exponential function? b) Predict the chirping rate for 70o F. and 100o F. c) What would you predict the temperature to be if you counted 150 chirps per minute?

A Geiger counter beeps according to a Poisson process with rate of 1 beep per minute. (a). Let N_1 be the number of beeps in the first minute, N_2 the number of beeps in the second minute, N_3 the number of beeps in the third minute, etc. Let K be the smallest number for which N_K = 0, so minute # K is the first minute without a beep. Find E(K). (b). What is the probability that the time until...

The resting heart rate for an adult horse should average about μ = 42 beats per minute with a (95% of data) range from 18 to 66 beats per minute. Let x be a random variable that represents the resting heart rate for an adult horse. Assume that x has a distribution that is approximately normal. (a) The empirical rule indicates that for a symmetrical and bell-shaped distribution, approximately 95% of the data lies within two standard deviations of the...

Methane gas (CH4) at 25 °C is burned steadily with dry air, which enters a combustion chamber of a natural gas boiler in a small power plant at 17 °C. The volumetric analysis of the flue gas on a dry basis is 5.2% carbon dioxide, 0.33% carbon monoxide, 11.24% diatomic oxygen, and 83.23% diatomic nitrogen. The flue gas leaves at 700 K. a) Sketch a fully labelled schematic diagram of the system. b) Write a balanced chemical equation for the...
