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- [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
Answer:
$475,000
Step-by-step explanation:
Since the profits increase by 5% each year, this means that each year the new profit is 105% of the old ones.
To find last year's profits, we divide this year's by 105%, or 1.05:
500000/1.05 = 476190.48
This means the profits last year were about $475,000.
Answer:
(3/2,0)
Step-by-step explanation:
use the midpoint formula:
(x1+x2/2,y1+y2/2)
(7-4/2)=3/2
(-2+2/2)=0/2=0
