In 1978, researchers premack and woodruff published a study in science magazine, reporting an experiment where an adult chimpanzee named sarah was shown videotapes of eight different scenarios of a human being faced with a problem. after being shown each videotape, she was presented with two photographs, one of which depicted a possible solution to the problem. for example, a problem might be a human trying to grab an object just out of reach. the picture of the correct solution would show the human stepping on a box to be able to reach further. in the experiment, sarah picked the photograph with the correct solution seven times out of eight. if sarah were simply guessing, for how many of the eight problems would you expect her to correctly identify the possible solution?

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?
