The answer is "Option a".
Step-by-step explanation:
Using the binomial distribution:

In this the maximum value which is significantly low,
, and the minimum value which is significantly high,
, that is equal to:

Answer:
20
Step-by-step explanation:
(x + 1)·(x + 1 + 11) = (x + 4)·(x + 4 + 1) --> x = 2
Tools like "photomath" are able to help you solving such equations.
Answer: Rate of A: 5/6
Rate of B: 3/5
A has a higher rate of change
Step-by-step explanation: You calculate slope/rate of change by determining the rise over the run. The rate of change in A is 5/6x, this is bigger than the slope of B.
