An executive for a large company is considering a change to health insurance plans offered to the employees. To assess employee satisfaction with the current plan, the executive sends an email to
all company employees asking
their opinion of the current plan. A summary of the results received shows that 27% of company employees are
"highly satisfied" with the current health insurance plan. Which statement about the results is most likely to be
true?

A) The results may suffer from undercoverage because the opinions of segments of employees may not be recorded.
B) The results provide an accurate representation of support because the opinion of all employees has been
recorded.
C) The results may suffer from nonresponse bias because many satisfied employees may choose to not respond to
the email survey
D) The estimate of 27% for employee support of the health plan is likely accurate because all company employees
were contacted via email.

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?
