Answer:
2n(14n^2+3)=28n^4+16n I'm not sure if you meant to put the question mark between or not but I did it separately for -80^2=0 n would equal zero hope this helped
Step-by-step explanation:
Answer:
A. there is a 99% probability that μ is between 3 and 9.
Step-by-step explanation:
From a random sample, we build a confidence interval, with a confidence level of x%.
The interpretation is that we are x% sure that the interval contains the true mean of the population.
In this problem:
99% confidence interval.
6 ± 3.
So between 6-3 = 3 and 6 + 3 = 9.
So we are 99% sure that the true population mean is between 3 and 9.
So the correct answer is:
A. there is a 99% probability that μ is between 3 and 9.
Answer:
The width of the drawer is ![15\ in](https://tex.z-dn.net/?f=15%5C%20in)
Step-by-step explanation:
we know that
The volume of the drawer is equal to
![V=LWH](https://tex.z-dn.net/?f=V%3DLWH)
we have
![L=15\ in](https://tex.z-dn.net/?f=L%3D15%5C%20in)
-----> the deep of the drawer
![V=1,125\ in^{3}](https://tex.z-dn.net/?f=V%3D1%2C125%5C%20in%5E%7B3%7D)
substitute the given values in the formula and solve for W
![1,125=(15)(W)(5)](https://tex.z-dn.net/?f=1%2C125%3D%2815%29%28W%29%285%29)
![1,125=(75)(W)](https://tex.z-dn.net/?f=1%2C125%3D%2875%29%28W%29)
![W=1,125/(75)](https://tex.z-dn.net/?f=W%3D1%2C125%2F%2875%29)
![W=15\ in](https://tex.z-dn.net/?f=W%3D15%5C%20in)
Answer:
110 pages
Step-by-step explanation:
The rate of 55 pg in 30 minutes is given in "minutes".
Thus,
we need to convert 1 hour to minutes.
We know 1 hour = 60 minutes
Note: 30 mins * 2 = 60 minutes
Logically, 30 minutes makes 55 pages, so 60 minutes (30 * 2) will make 55 * 2 = 110 pages
So, in 1 hour, it can print 110 pages (at this rate)
