Answer:
<u>Hay 2.5 decámetros en 25 metros.</u>
Step-by-step explanation:
Aqui solo debemos recordar la relacion de metros a decámetros.
1 decámetro = 10 m
Entonces 25 metros seran:
![\frac{1\: decametro}{10\: m}=\frac{x\: decametro}{25\: m}](https://tex.z-dn.net/?f=%5Cfrac%7B1%5C%3A%20decametro%7D%7B10%5C%3A%20m%7D%3D%5Cfrac%7Bx%5C%3A%20decametro%7D%7B25%5C%3A%20m%7D)
![x=\frac{25\: m*1\: decametro}{10\: m}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B25%5C%3A%20m%2A1%5C%3A%20decametro%7D%7B10%5C%3A%20m%7D)
![x=\frac{25*1}{10}=2.5\: decametros](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B25%2A1%7D%7B10%7D%3D2.5%5C%3A%20decametros)
<u>Por lo tanto, hay 2.5 decámetros en 25 metros.</u>

Compute the unit rates.
Tank A:
(5/8 gal) / (1/2 min) = 10/8 gal/min = 5/4 gal/min = 1.25 gal/min
Tank B:
(3/5 gal) / (1/4 min) = 12/5 gal/min = 2.2 gal/min
So tank B is filling faster.
Answer: 7 times greater because there are 7 days in a week
Group the like terms to get 5m+6w+33.
Answer:
n=1705
Step-by-step explanation:
The margin of error is the range of values below and above the sample statistic in a confidence interval.
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".
Assuming the X follows a normal distribution
And the distribution for
is:
We know that the margin of error for a confidence interval is given by:
(1)
The next step would be find the value of
,
and
Using the normal standard table, excel or a calculator we see that:
If we solve for n from formula (1) we got:
And we have everything to replace into the formula:
And if we round up the answer we see that the value of n to ensure the margin of error required
mm is n=1705.
