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
The measure of the angle <u>x = 90°</u>
<u>Theorem Of Tangent</u>:-
A radius is obtained by joining the centre and the point of tangency. The <u>tangent at a point on a circle is at right angles to this radius</u>.

Answer:
x = 9
Step-by-step explanation:
The sum of interior angles in a triangle is 180°.
Let's say the measure of the angles are 3x, 10x, and 7x.
3x + 10x + 7x = 180
20x = 180
<u>x = 9</u>
