Answer:
Option b that is 1.33 is the right choice.
Step-by-step explanation:
Given:
Mean rate of arrival 
= 8 planes/hr
Service time = 
minute/plane
Mean service rate 
= 
= 
planes/hr
Applying the concept Poisson-distributed arrival and service rates (exponential inter-arrival and service times)(M/M/1) process:
We have to find mean number of planes waiting to land that is mean number of customers in the queue .
Mean number of customers in queue 
.
⇒ 
Considering, 
, 
is also mean number of customers in service.
⇒ 
⇒ Plugging the values.
⇒ 
⇒ 
⇒ 
So,
Mean number of planes in holding and waiting to land = 1.33
Answer:
the surface area is not equal to 296 sq ft.
Step-by-step explanation:
There are total six faces of the given rectangular prism
Area of the top and bottom face is equal to 288 Sq ft
Area front face and the face at the back = 2 * 2 * 144 = 576 Sq. ft.
Area of the other two sides is = 2 * 2 * 144 = 576 Sq. ft.
The total surface area of the prism is 576 +576 + 288 = 1440 Sqft
No, the surface area is not equal to 296 sq ft.
Answer:
1 is multipy the last term by 1/6
2 is geometric because you multiply by 2 every time.
3 is arithmitic sequence because you subtract 20 every time
Step-by-step explanation:
