Step-by-step explanation:
1) 7/23 + 11/23 + 9/23
7+11+9/23
27/23
= 1 4/23
2) 2 5/7 + 9 4/7
11 9/7
= 11.12
3) 9/20 + 3/5
9+12/20
21/20
= 1 1/20 or 1.05
Answer:
The probability of failure of trial 11 is 
Step-by-step explanation:
Generally one the attributes of a binomial experiment is that the probability of success and failure is constant every trial so given from the question that the probability of success is 0.84 for trial 7 , then the probability of failure of trial 7 will be evaluated as

=> 
And from the attribute stated above the probability of failure of trial 11 is 
Answer:
See below in bold.
Step-by-step explanation:
The domain is the list of x values and the range is the list of y values.
Reading from the graph: The domain is {-3.5, -2, 0, 3.5}.
The range is {3, 1.5, -0.5, }.
The next nearest hundred for this equation is 1,000 so the answer is 5,000.
I hope this helps ;)
