Most chickens reach maturity and begin laying eggs at around 20 weeks of age. From this point forward, however, as the chicken ages,its eges its egg production decreases. A farmer was given a flock of 100 chickens (all of which were the same age) and asked to meaure daily egg output for the entire flock at random intervals starting at maturity until the chickens were 70 weeks old. The data are recorded in the scatteplot below and the line of best fit has been drawn. Based on the line of bast fit, what is the predicted number of eggs that will be produced by the flock when it is 33 weeks past maturity ?

A child running a temperature of 101^F is given and antipyrin (i.e. a madicine that lowers fever) which cause an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98^@F in 20 min., what is the averatge rate of extra evaporation caused, by the drug ? Assume the evaporation mechanism to the only way by which heat is lost. The mass of the child is 30 kg. The specific heat of human body is approximately the same as that of water and latent heat of evaporation of water at that temperature is about 580 cal. g^(-1).
