To know how far your values differ apart from the mean of the records
Answer:
E. Each trial is independent
Step-by-step explanation:
I'm not completely sure why all binomial distribution trials are independent, but there are requirements for binomial distributions.
These requirements are:
- Each outcome is either a success (p) or a failure (Q)
- All trials are independent
- There are a fixed number of "n" trials
- The probability of success (p) is the same for each trial
I also just took the test and got this right.
The system of solution is at the point (-6,24)
We know that
[volume of a sphere]=(4/3)*pi*r³
volume=81*pi cm³
so
81*pi=(4/3)*pi*r³
therefore
the answer is the option
