Asales representative for a baby food company wants to survey 300 random couples who are new parents to find out if their newborn child is a boy or a girl. the rep uses a 1 for a girl and a 2 for a boy when running a simulation. would the simulation be a fair representation of possible survey results? why or why not? a. yes, because each of the two outcomes are equally likely. b. no, because each of the two outcomes are not equally likely. c. no, because the survey includes 300 results. d. yes, because the survey includes 300 results.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
