As a transportation manager for a distribution
warehouse, you need to determine the time to
allow for delivery of a truck load of equipment.
the truck has one driver, so the maximum legal
driving time is 11 hours per day. in order to
calculate the total driving time for the delivery,
you use average times in your records for the
four segments of the route: 13 hours, 45 minutes;
8 hours, 30 minutes; 10 hours, 45 minutes;
2 hours, 15 minutes. how many days should
you allow for the delivery?

Kathy spent 5/8 of her money on books and another 1/6 of her money on stationeries.what fraction of kathy’s money was left?

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
