Answer:

A. 57 mL/hr

Step-by-step explanation:

Mass of morphine sulfate = 125 mg

DW = 250 mL

Rate of infusion = 0.005 mg/kg/min

Converting to mg/kg/hour

0.005 mg/kg/min×60 = 0.3 mg/kg/hour

For the patient who weighs 95 kilograms

0.3 mg/kg/hour×95 = 28.5 mg/hour

For the mass of 125 mg of morphine sulfate

1 mg

250/150 = 2 ml/mg

Rate of infusion

28.5×2 = 57 mL/hr

∴ Rate of infusion is 57 mL/hr

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).

What is the distance, to the nearest whole number, from K (5, 6) to P (1, 1)?

Elza [17]

Answer:

<h3>The answer is 6 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

K (5, 6) P (1, 1)

The distance from K to P is

$|KP| = \sqrt{ ({5 - 1})^{2} + ({6 - 1})^{2} } \\ = \sqrt{ {4}^{2} + {5}^{2} } \\ = \sqrt{16 + 25} \\ = \sqrt{41} \\ = 6.403124$

We have the final answer as

<h3>6 units to the nearest whole number</h3>

Hope this helps you

Myra won the hurdles event for the seventh graders. She completed the race in 22.8 seconds and knocked down 1 hurdle. Byron won

Nadya [2.5K]

Answer:

Myra: 24.8s (winner)

Byron: 26.3s

Step-by-step explanation:

Myra knocked down 1, so therefore there are 2 points added onto her time and it is now 24.8s.

Byron knocked down 3, so there are 6 points added on for 2 seconds per each hurdle. His time is now 26.3

A four-person committee is chosen from a group of eight boys and six girls.

Stolb23 [73]

Answer:

The probability is approximately 0.0699. That's $\displaystyle \frac{10}{143}$ to be exact.

Step-by-step explanation:

How many ways to choose four out of a total of $8 + 6 = 14$ boys and girls?

$\displaystyle {14\choose 4} = 1001$ .

How many ways to choose four boys out of a total eight boys?

$\displaystyle {8\choose 4} = 70$ .

What's the probability that all four persons chosen out of the pack of fourteen are boys? All 1001 ways of choosing four out of fourteen are equally likely. However, only 70 satisfy the conditions. In other words, the probability of choosing four boys out of this group of eight boys and six girls is equal to:

$\begin{aligned}&\frac{\text{Number of ways to choose four out of eight}}{\text{Number of ways to choose four out of fourteen}} \\= &\frac{70}{1001}\\=& \frac{10}{143}\approx 0.0699\end{aligned}$ .
