Answer:
1 hour working on problems, 3 hours reading
Explanation:
the question is not complete:
Bob is a hard-working college freshman. One Tuesday, he decides to work nonstop until he has answered 200 practice problems for his chemistry course. He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him longer to solve each problem.
Time Total Problems Answered Marginal gain
8:00 AM 0
9:00 AM 80 80
10:00 AM 140 60
11:00 AM 180 40
Noon 200 20
Since Bob's is able to answer more than 70 questions per hours only during one hour (from 8 to 9 AM), he can benefit more from reading the next 3 hours. Reading would be equivalent to answering 210 questions, while Bob was only able to answer 120 more questions in the following 3 hours.
Answer:
The correct answer is b) a Ponzi scheme.
Explanation:
The Ponzi Scheme is a fraudulent investment operation that involves paying investors interest obtained from the money of new investors (and not from the generation of genuine profits). It is a pyramidal system, in which the only way to share benefits requires that participants recommend and capture (refer) to more clients with the objective that new participants produce benefits to primary participants.
This system does not invest in financial or other instruments, it only redistributes money from some investors to others, so the system works only if the number of investors in the pyramid continually grows; once people stop entering the "business", the scammer is prevented from fulfilling his promise and the pyramid collapses
Answer:
This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreaseddecreased because belowbelow 0.10 because the proportion of sample, is nothing very close to 0.10.
Explanation:
n = 1100
p = 0.10
Using the formula np(1-p), we will have
= 1100(0.10)*(1 - 0.10)
= 1100*0.10*0.90
= 99
99 ≥ 10
This satisfies normal distribution condition. That is, proportion of sample are normally distributed.
Answer:
$ 142,800.00
Explanation:
The ending inventory can be computed by rearranging the cost of goods sold formula:
cost of goods sold=Beginning inventory+net purchases-ending inventory
ending inventory=beginning inventory+net purchases-cost of goods sold
beginning inventory is $92,000
Net purchases=purchases-discount+freight-in charges-purchase return
net purchases=$425,000-($425,000*1%)+$7000-($5000*99%)=$422,800.00
cost of goods sold is $372,000
ending inventory=$92,000+$422,800-$372,000=$ 142,800.00
