There is a linear relationship between the number of chirps made by a cricket and the air temperature . A least-squares fit of data collected by a biologist yields the equation:
temp`(""^(@)F)` = 22.8 + (3.4)(#chirps/min)
What is the estimated increase in temperature that corresponds to an increase of 5 chirps per minute ?

T=25+3c The equation above is used to model the number of chirps, c, made by a certain species of cricket in one minute, and the temperature, T, in degrees Fahrenheit. According to this model, what is the meaning of the number 3 in the equation.

The graph shows the correlation between ambient air temperature, t, in degress Fahrenheit and the number of chirps, c, per minute that a snowy tree cricket makes at that temperature. Which of the following equations represents the line shown in the graph ?

Newton’s law of cooling says that the rate of cooling of a body is proportional to the temperature difference between the body and its surrounding when the difference in temperature is small. (a) Will it be reasonable to assume that the rate of heating of a body is proportional to temperature difference between the surrounding and the body (for small difference in temperature) when the body is placed in a surrounding having higher temperature than the body? (b) Assuming that our assumption made in (a) is correct estimate the time required for a cup of cold coffee to gain temperature from 10^(@)C to 15^(@)C when it is kept in a room having temperature 25^(@)C . It was observed that the temperature of the cup increases from 5^(@)C to 10^(@)C in 4 min

Keshav observed that the increase in the temperature of a body is given by T_(1) = 2t^(2) for the first 5 minutes and T_(2) = 3t for the next 5 minutes, where T_(1) , T_(2) and 't' are temperatures in Fahrenheit, Celsius scales and time in minutes, respectively. If the initial temperature of the body is 20^(@)F and the relation between the Celsius and Fahrenheit scale is, then find the temperature of the body after 8 minutes in Celsius scale.
