If you copy a page on a machine at 72%, you should get a similar copy of the page. What is the corresponding setting to obtain t

allsm [11]

Answer:

$138\frac{8}{9}\%$

Step-by-step explanation:

we know that

To find out the corresponding setting to obtain the original from the copy, divide 100% by 72%

$\frac{100}{72}$

Simplify

$\frac{100}{72}=\frac{25}{18}$

Convert to percentage

$\frac{25}{18}(100)=\frac{2,500}{18}\%$

Simplify

$\frac{2,500}{18}\%=\frac{1,250}{9}\%$

Convert to mixed number

$\frac{1,250}{9}\%=\frac{1,242}{9}+\frac{8}{9}=138\frac{8}{9}\%$

In the country of United States of Heightlandia, the height measurements of ten-year-old children are approximately normally dis

Softa [21]

Answer:

$P(49.5$

$P(-1.192$

Step-by-step explanation:

We define X the random variable that represent the heights of a population for ten year old children, and for this case we know the distribution for X is given by:

$X \sim N(55.7,5.2)$

Where $\mu=55.7$ and $\sigma=5.2$

We want to find this probability:

$P(49.5$

We can use the z score formula to solve this problem given by:

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

Using this formula we have:

$P(49.5$

And we can find this probability with this difference

$P(-1.192$

We can use tables for the normal standard distribution, excel or a calculator and we got this

$P(-1.192$

Answer:

4(1000) +11(100) + 24(10,000) +11(1000) = 256,100

Step-by-step explanation:

Maybe you want to add 4000 +1100 to 24(10,000) +11,000.

1 thousand = 10 hundreds, so 4000 = 40 hundreds

4000 +1100 = (40 +11) hundreds = 51 hundreds

1 ten-thousand = 10 thousands, so 24(10,000) = 240 thousands

24(10,000) +11,000 = (240 +11) thousands = 251 thousands

So, we want to add 251,000 and 51 hundreds. The latter can be considered to be 5000 +100, so we have ...

251,000 +5100 = 251,000 +5,100 = (251 +5) thousands + 1 hundred

= 256,100
