Step-by-step explanation:
3 sigma= 3×0.146
= 0.438
for upper limit= sample mean + 3 sigma
for lower limit= sample mean - 3 sigma
Answer: 0.040

Answer:
2/9, 2/27
Step-by-step explanation:
54, 18, 6, 2, 2/3
Take the second term and divide by the first
18/54 = 1/3
We multiply by 1/3
Check by taking the third term and dividing by the second
6/18 = 1/3
This works
Take the last term and multiply by 1/3
2/3*1/3 = 2/9
2/9*1/3 =2/27

Answer:
D. 5.4
Step-by-step explanation:
The point U divides segment SP into the ratio 1 : 2. So, segment SU is 1/2 the length of segment UP.
SU = UP/2 = 3.6/2 = 1.8
The length of PS is ...
PS = PU +US = 3.6 +1.8
PS = 5.4

If you were asked to find the value of x, you would discover x=1. That is not what you're asked here.
Using a system of equations, it is found that <u>since the solution of the system does not involve decimal numbers</u>, it is possible to arrange the books in this way.
For the system, we consider that:
- x is the number of books on the first shelf.
- y is the number of books on the second shelf.
- z is the number of books on the third shelf.
In total, there are 152 books, hence:

The first shelf has 7 fewer books than the second shelf, hence:

Also, it has 11 more books than the third shelf, hence:

Then:


Then, replacing in the first equation:





The number of books in each shelf has to be countable, that is, cannot be decimal.
- Then, <u>since the solution of the system does not involve decimal numbers</u>, it is possible to arrange the books in this way.
