Answer:
2,000 miles
Step-by-step explanation:
We are given:
![1 inch=500 miles](https://tex.z-dn.net/?f=1%20inch%3D500%20miles)
This can be rewritten as:
![\frac{500 miles}{1inch}](https://tex.z-dn.net/?f=%5Cfrac%7B500%20miles%7D%7B1inch%7D)
This is representative of a unit rate, as we have a
in the denominator. To calculate the number of miles in
inches, simply multiply the unit rate by
:
![\frac{500 miles}{1inch}*4=](https://tex.z-dn.net/?f=%5Cfrac%7B500%20miles%7D%7B1inch%7D%2A4%3D)
![\frac{2000 miles}{4 inches}](https://tex.z-dn.net/?f=%5Cfrac%7B2000%20miles%7D%7B4%20inches%7D)
This can rewritten as:
![4inches=2000miles](https://tex.z-dn.net/?f=4inches%3D2000miles)
Therefore, there are 2,000 miles in 4 inches.

We can check our solution by simplifying the fraction
by dividing both
and
by
to see if we achieve the unit rate:
![\frac{500 miles}{1 inch}](https://tex.z-dn.net/?f=%5Cfrac%7B500%20miles%7D%7B1%20inch%7D)
Since this is in fact the unit rate, our solution is correct!
Each line indicates the amount of a certain object.
We already know that the value of the green line is 15, all that is left to do is find the rest . . .

Answer:
And we can find this probability with this difference:
And if we use the normal standard distribution or excel we got:
Step-by-step explanation:
Let X the random variable that represent the time required to construct and test a particular component of a population, and for this case we know the distribution for X is given by:
Where
and
We want to find this probability:
And the best way to solve this problem is using the normal standard distribution and the z score given by:
Using this formula we got:
And we can find this probability with this difference:
And if we use the normal standard distribution or excel we got:
