When a customer places an order with a certain company's on-line supply store, a computerized accounting information system (ais) automatically checks to see if the customer has exceeded his or her credit limit. past records indicate that the probability of customers exceeding their credit limit is 0.08. suppose that, on a given day, 22 customers place orders. assume that the number of customers that the ais detects as having exceeded their credit limit is distributed as a binomial random variable. complete parts (a) through (d) below. a) what is the mean of customers exceeding their credit limits?
b) what is the standard deviation of the customers?
c) what is the probability that 0 customers exceed their credit limits?
d) what is the proability that 1 customer will exceed their credit limits?
e) what is the probability that 2 customers will exceed their credit limits?

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?
