First of all, there are a few things you should know:

1) Area of a cylinder: $\pi r^{2} h$
2) Area of a cone: $\frac{1}{3} \pi r^{2} h$

To solve this, just plug it in:

Cylinder: $\pi * 2^{2} * 7 = 28 \pi$
Cone: $\frac{1}{3} * \pi * 2^{2} * 3 = 4 \pi$

The total is $32 \pi$

Wendy's restaurant has been recognized for having the fastest average service time among fast food restaurants. In a benchmark s

VikaD [51]

Answer:

(a) 0.2885

(b) 0.0736

(c) 0.0468

Step-by-step explanation:

The exponential distribution of Wendy's service time is given by:

P(x) = [exp (-x/μ)]/μ............................................................................ (1)

P(x) = Probability function

x = Service time, in minute

μ = average service team, in minute, 2.2 minutes

(a) x= 1, substituting into equation (1) we have:

P(1) = [exp (-1/2.2)]/2.2

= 0.6347/2.2

= 0.2885

(b) x₁ = 0.5 minutes

x₂ = 1 minute

P (0.5<x<1) = P(0.5) -P(1) ----------------------------------------------- (2)

From (a), P (1) = 0.2885

P(0.5) =P(1) = [exp (-0.5/2.2)]/2.2

= 0.7967/2.2

= 0.3621

Substituting into (2), we have :

P (0.5<x<1) = 0.3621 -0.2885

= 0.0736

(c) P(5) = [exp (-5/2.2)]/2.2

= 0.1030/2.2

= 0.0468
