A = 1/2 bh

multiply each side by 2

2A = bh

divide each side by b

2A/b =h

Answer:

h = 2A/b

Step-by-step explanation:

A=1/2bh

multiply left n right by 2/b, 2A/b=h

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:

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

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\\sqrt{(-27-27)^2+(36+36)^2}\\\\ \sqrt{54^2+72^2} \\\\ \sqrt{8100} \\\\90\\\\\\90+54 =\boxed { 144}\\\\\sf The~ distance~ 90~ is~ from ~the~ warehouse~ to ~the ~airport\\\\The~ distance~ 54~ is~ from ~the~ airport~ to ~the~ factory\\\\So,~ the~ total~ distance~ is~ 144$
