No. of diners = 240
Musya8 [376]

Answer:

<u>We need to buy 3 cases of juice.</u>

Correct statement and question:

No. of diners = 240 Portions of juice served = 4 oz. per diner Size of juice can = 48 oz. How many cases of juice required if there are 8 cans in a case and you must buy a whole case?

Source:

Previous question that you can search at brainly

Step-by-step explanation:

Let's calculate the number of cases of juice are required this way:

Number of cases required = [(Number of dinners * portion of juice served)/Size of juice can]/Cans in a case

Replacing with the real values, we have:

Number of cases required = [(240 * 4)/48]/8

Number of cases required = [(960)/48]/8

Number of cases required = 20/8

Number of cases required = 2.5

<u>But let's remember that we must buy only whole cases, then we need to buy 3 cases of juice.</u>

If cosX = -0.2, and x is in quadrant II, then what it the value of sinX​
Tems11 [23]

\sin x>0 when x is in quadrant II, so

\cos^2x+\sin^2x=1\implies\sin x=\sqrt{1-\cos^2x}=\sqrt{1-(-0.2)^2}\approx1.02

A new pop-up restaurant serving high-end street tacos just opened and is expected to have high demand based on the chef's prior
Harman [31]

Answer:

1. c

2. f

3. d

Step-by-step explanation:

This type of queuing model is an example of "single-channel, single-phase" process.

However, from the information given:

The inter-arrival rate = 10 customers per hour

Arrival time = 6 minutes

Service time = 5 minutes

∴

utilization = service time/arrival time

= 5/6

Time on queue T_q = p \times \dfrac{utilization }{1 - utilization} \times \dfrac{Cv_a^2 -Cv_b^2}{2}

T_q = 5 \times \dfrac{5/6 }{1 -5/6} \times \dfrac{(2.58^2 -0.75^2)}{2}

T_q = 25 \times 3.60945

T_q = 90.24 \\ \\ T_q \simeq 90 \ mins

Thus, customer waiting in the queue line is;

= \dfrac{T_q}{q}  \\ \\ = \dfrac{90}{6} \\ \\ \mathbf{=15}

Thus, new customers will have to wait in a total time of;

= waiting time + service time

= 90 + 5

= 95 minutes.
