A cup of hot coffee has been left to cool in a room with an ambient temperature of 21°C.
The relationship between the elapsed time, m, in minutes, since the coffee was left to cool, and the
temperature of the coffee, T, measured in °C. is modeled by the following function.
T(m) = 21 + 74.10 0.03m
What will the temperature of the coffee be after 10 minutes?
Round your answer, if necessary, to the nearest hundredth.

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels. ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis?
