If you mutilply, you times the d and n together. If you divide, you have to switch the d and n around for the 2nd fraction. then you do the same thing as you mutiply.

A soft drink machine outputs a mean of 24 ounces per cup. The machine's output is normally distributed with a standard deviation

Arisa [49]

Answer:

$P(21$

And we can find the probability with this difference

$P(-1$

And using the normal standard distribution or excel we got:

$P(-1$

Step-by-step explanation:

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

$X \sim N(24,3)$

Where $\mu=24$ and $\sigma=3$

We want to find this probability:

$P(21$

The z score is given by:

$z=\frac{x-\mu}{\sigma}$

Using this formula we got:

$P(21$

And we can find the probability with this difference

$P(-1$

And using the normal standard distribution or excel we got:

$P(-1$

Round 5,762.384 to the nearest ten

swat32

If it's nearest ten then it would be 5,760. If anything is 4 or lower than the number, like 74, then it would be 70.
If it was 5 or higher, like 37, then it would become 40.
Hope this helps! :)
