Yes he is correct because the 3 was in the tenths place. so say that the 3 is in the ones place multiply it by 10 and equales 3000. so you are just taking one zero with it
You can combine the same numbers with the same variables using the operation sign for each. For example, using your equation, you would combine the 3n and 4n which is 7n. So your equation would be
7n - 2
With 'random sampling' every item in the population has an equal probability of being selected.
Answer:
.88
Step-by-step explanation:
We can use this equation:

Where:
- N is the increase factor (N=512)
- R is the reduce factor (R=8)
- D is the dimension

We just need to solve it for D

.88
Therefore the dimension will be 3
