Mathematics

Feliz [49]2 years ago
5 0

Answer:

4000 gm

Step-by-step explanation:

We can use ratios to solve

Change 8 m to cm

8m * 100cm/1m = 800 cm

6 cm             800 cm

-------------  = ------------

30 grams      x gm

Using cross products

6 * x = 800 * 30

6x = 24000

Divide by 6

6x/6 = 24000/6

x = 4000 gm

Customers enter the waiting line to pay for food as they leave a cafeteria on a first-come, first-served basis. The arrival rate
Elan Coil [88]

Answer:

The answer is B) 0.57.

Step-by-step explanation:

In this problem we have to apply queueing theory.

It is a single server queueing problem.

The arrival rate is  \lambda=4 and the service rate is \mu=7.

The proportion of time that the server is busy is now as the "server utilization"and can be calculated as:

p=\frac{\lambda}{c\mu} =\frac{4}{1*7}=0.57

where c is the number of server (in this case, one server).

Bond [772]

Answer:

Oliver completed his training work in 50.25 hours

Step-by-step explanation:

we know that

1\ day= 24\ hours

1\ hour=60\ minutes

we have

2\ days, 2\ h,\ and\ 15\ min

<u><em>Convert days to hours</em></u>

2\ days=2(24)=48\ hours

<u><em>Convert minutes to hour</em></u>

15\ min=15(1/60)=1/4=0.25\ h

so

2\ days, 2\ h,\ and\ 15\ min=(48)+(2)+(0.25)=50.25\ h

therefore

Oliver completed his training work in 50.25 hours
