Use differentials to estimate the amount of material in a closed cylindrical can that is 6060 cm high and 2424 cm in diameter if the metal in the top and bottom is 0.10.1 cm thick, and the metal in the sides is 0.10.1 cm thick. note, you are approximating the volume of metal which makes up the can (i. e. melt the can into a blob and measure its volume), not the volume it encloses. the differential for the volume is

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?
