Cargo ships arrive at a loading dock at a rate of 2 per day. The dock has the capability of handling 3 arrivals per day. How man
Vsevolod [243]

Answer:

4 days

Step-by-step explanation:

We need to use the probability functions of each of the intervals to know the Probability number and then use it in the expected value.

P(x>3 cargo ships) = 1-P(x<=3)

P(x>3) = 1-P(x<=3)

P(x>3) = 1-[P(x=0)+P(x=1)+P(x=2)+P(x=3)]

P(x>3) = 1 - [\frac{e^{-2}2^0}{01}+\frac{e^{-2}2^1}{11}+\frac{e^{-2}2^2}{21}+\frac{e^{-3}2^3}{31}]

P(x>3) = 1- [0.1353(1+2+2+1.33)]

P(x>3) = 1-0.856

P(x>3) = 0.1431

Als n=30, expected number is

E(x) =30*P(x>3)

E(x) = 30*0.1431

E(x) = 4.293

I expect 4.293 or 4 days per month the block being unable to hanlde all arriving ships

A school sport's team sold hats for $12 each hat. The team made a profit of $3 for each hat sold. What percent of the selling pr
disa [49]

Answer: 25%

Step-by-step explanation:

Given: Selling price of each hat = $12

Profit on each hat = $3

To find: The percent of the selling price of each hat is the profit.

Ratio of profit to selling price = \dfrac3{12}=\dfrac14

The required percentage = Ratio of profit to selling price x 100

=\dfrac14\times100=25\%

The profit is 25% of the selling price.
