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.
Answer:
8
Step-by-step explanation:
2015: 9 games won
2014: 1 game won
rate of change = 2015 games won - 2014 games won
rate of change = 9 - 1
rate of change = 8
Answer:
48%
Step-by-step explanation:
In order to find the percentage, we'll have to divide the number of successful sales by the total number of sales.
= 0.48
0.48 written as a percentage is 48%
Answer:
12
Step-by-step explanation:
This is assuming that x2 means x to the power of 2 and that the x on the left is to represent multiplying. First, plug in all of the number to get 2*3+3^2-3.Using PEMDAS, you should solve the exponent to get 9. Then, multiply 2 by 3 to get 6. Add 6 to 9 to get 15. Subtract 2 to 15 to get 12.
TL;DR
2*3+3^2-3
6+9-3
15-3
12
