Intravenous fluid bags are filled by an automated filling machine. Assume that the fill volumes of the bags are independent, nor

kenny6666 [7]

Answer:

a) 0.0167

b) 0

c) 5.948

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 6.16 ounces

Standard Deviation, σ = 0.08 ounces

We are given that the distribution of fill volumes of bags is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) Standard deviation of 23 bags

$\displaystyle\frac{S.D}{\sqrt{23}} = \frac{0.08}{\sqrt{23}} = 0.0167$

b) P( fill volume of 23 bags is below 5.95 ounces)

P(x < 5.95)

$P( x < 5.96) = P( z < \displaystyle\frac{5.95 - 6.16}{0.0167}) = P(z < -12.57)$

$= 1 - P(z < 12.57)$

Calculation the value from standard normal z table, we have,

$P(x < 5.95) = 1 - 1 = 0$

c) P( fill volume of 23 bags is below 6 ounces) = 0.001

P(x < 6) = 0.001

$P( x < 6) = P( z < \displaystyle\frac{6 - \mu}{0.0167})$

Calculation the value from standard normal z table, we have,

$P( z \leq -3.09) = 0.001$

$\displaystyle\frac{6 - \mu}{0.0167} = -3.09\\\\\mu = 6 + (0.0167\times -3.09) = 5.948$

If the mean will be 5.948 then the probability that the average of 23 bags is below 6.1 ounces is 0.001.

If a number is decreased by 8, the result is -21. What is the

wariber [46]

Answer:

answer = -13

Step-by-step explanation:

number = x

x - 8 = -21

x = -21 + 8

= -13

Recheck :

num = - 13

decreased by 8 = - 13 -8 = -21

A can of crushed tomatoes holds 40 fluid ounces. How can a label designer name the same volume using metric units? Complete the

inn [45]

The metric unit of a quantity is simply the unit of measurement of the quantity

The volumes of the crashed tomato cans are 1184 milliliters and 1.184 liters

The volume of the crushed tomato can is given as:

$\mathbf{Volume = 40oz}$

From the question, we have the following conversion ratio

$\mathbf{1oz \approx 29.6mL}$

So, the volume in milliliters becomes

$\mathbf{Volume = 40 \times 29.6mL}$

Multiply

$\mathbf{Volume = 1184mL}$

To convert the unit to liters, we simply divide the volume by 1000.

So, we have:

$\mathbf{Volume = 1184L \div 1000}$

$\mathbf{Volume = 1.184L}$

Hence, the equivalent volumes are 1184 milliliters and 1.184 liters
