() is for < and >
[] is for ≤ and ≥
(a,b) means from a to b, not including a or b
(a,b] means from a to b, not including a, but including b
so
x<-3
so from -3 to less of that or
from -∞ to -3
you can't equal -∞, so we use parnthasees
also, it is < so we use parnthaees
(-∞,-3)
Answer: The correct answer is Choice 4.
The Pythagorean Theorem is about the relationships between the side lengths of a triangle.
When a triangle is a right triangle the sides are in the form of: a^2 + b^2 = c^2
If you want to determine if a triangle is a right triangle, just plug the values into this equation and see if it is true.
Therefore, you should first know the sides lengths.
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
