The chain on a bicycle connects the pedal gear (with a diameter of 9 inches) and a gear centered on the same axis as the back tire. The rear gear has a diameter of 3 inches, while the tires have diameters of 28 inches. A cyclist pedals at a rate of 2.25 revolutions per second.
Represent the angular velocity of the pedals in radians per second.
r=? so r/2=w
w=θ/t
w=?
anguluar velocity 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? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
