Answer:
The probability that 2 or 3 customers will arrive in a 15-minute period is 0.4703
Explanation:
Firstly, we have to determine the segment unit, since the mean is 10 per hour, the segment unit is 1 hour.
The mean(m) = 10
since the period is 15 minutes = 0.25 hour, t= 0.25 hour / 1 hour. Therefore mt= 2*10 = 2.5
The poisson distribution formula P(x) = 
Therefore the probability that 2 or 3 customers will arrive in a 15-minute period
P(x=2) or P(x=3) = P(x=2) + P(x=3) =
= 0.2565 + 0.2138 = 0.4703
Therefore P(x=2) or P(x=3) = 0.4703
The probability that 2 or 3 customers will arrive in a 15-minute period is 0.4703
Answer:
The interest on investment of $9000 and $1000 is 5.41 % and 4.81% respectively.
Explanation:
Let i be the interest rate on $ 9000 investment, then
9000i + 1000(i -0.006) = $ 535
10,000i = 541
i = 5.41 % on investment of $ 9000.
than on $1000 investment interest = 5.41-0.6 = 4.81 %
Answer:
This is a very unlikely situation, since the plant must be really large and the river probably didn't carry a lot of water in the first place. But even if this was possible, it would be illegal for a company to use 100% of the natural resources available. No law or regulation (municipal, state or federal) would allow such thing to happen and assuming it got to court, the court would rule against the company.
Since you need an environmental impact report before you start building a factory, then it would be unlikely that the factory or plant was legally authorized to operate in the first place. The only option is that they built a dam and that is highly regulated.
Answer:
b. His real salary has fallen and his nominal salary has risen.
Explanation:
If the assistant manager's salary rose but he can't afford the goods he used to buy last year , it means that his nominal salary rose.
Nominal salary is the sum of real salary and inflation rate.
Real salary is nominal salary less inflation rate.
Real salary measures the purchasing power of salary.
If with the salary increase, the assistant manager could buy more goods compared to last year, both nominal and real salary increased.
