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

iren2701 [21]

Answer:

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

$X \sim N(\mu,0.08)$

Where $\mu$ and $\sigma=0.08$

Since the distribution for X is normal then the we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And the standard error is given by:

$SE= \frac{0.08}{\sqrt{24}}= 0.0163$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

$X \sim N(\mu,0.08)$

Where $\mu$ and $\sigma=0.08$

Since the distribution for X is normal then the we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And the standard error is given by:

$SE= \frac{0.08}{\sqrt{24}}= 0.0163$

22nd term: 28, 23, 18, 13,..

Verizon [17]

Answer:

The 22nd Term is -77.

Step-by-step explanation:

The pattern is -5. If you subtract 5 from each starting number you'll get the following number.

Ex: 28 - 23 = 5

23 - 18 = 5

18 - 13 = 5

Subtract 5, 22 times and you will get -77.

I hope this was the most brainliest answer, thank you for letting me help you !

How would i explain how i got my answer (my answer was 200, all the other numbers were already there)

BigorU [14]

Step-by-step explanation:

80 times 2 is 160

Therefore, 100 times 2 is 200

You multiply the denominator and numerator by the same number.

If 5 pennies equal 7mm how much pennies is equal to 100mm

MAVERICK [17]

Divide 7 into 5 to find each penny value.
7/5 = 1.4
Thus, 1 penny is equal to 1.4 mm
100/1.4 = 71.43
Therefore 71.43 pennies is equal to 100mm.

|x-5|=3 <br> Whats x? please help?

finlep [7]

Answer:

x = 8 or x = 2

Step-by-step explanation:

We know x - 5 = 3 or x - 5 = -3.

<u>Possibility 1:</u>

Step 1: Add 5 to both sides.

$x-5+5=3+5$
$x=8$

<u>Possibility 2:</u>

Step 1: Add 5 to both sides.

$x-5+5=-3+5$
$x=2$

Step 2: Check if both solutions apply to original equation.

$|8-5|=3$
$|3|=3$
$3=3$
$|2-5|=3$
$|-3|=3$
$3=3$
