Answer:
I. $291.67 per passenger
II. $583.33 per passenger
Step-by-step explanation:
The cost of flying the passenger plane from A to B is $70,000.
If the Capacity of the plane is 240 people.
(I)At 7A.M and 4P.M., the average cost per passenger is given as:
Average Cost=Total Cost/Number of Passengers
=70000/240=$291.67 per passenger
(II)At 10AM and 1PM, the flight is only half full, it has 120 passengers.
Average Cost = 70000/120=$583.33 per passenger
I am doing this for points so i can catch up to my brother who is an expert
Answer:
3.30185
σ
8.7636
Step-by-step explanation:
the fromula for 100(1-α)% confidence (two sided) for σ is
√(η-1)*s^2/x^2_α/2,V
σ
√(η-1)*s^2/x^2_(1-α/2,V) ∴ (v=n+1)
now data given is n = 12 and s=5.2 mg
for 99% CI ,α=0.05 and (n-1)=9 degree of freedom
from chi- square table x^2_(0.025,9)=19.02 ; x_(0.975,9)=2.7
substitute them in above expression we get
3.30185
σ
8.7636
