Answer:
x = -8
Step-by-step explanation:
(-8, 7) and (-8, -2)
m=(y2-y1)/(x2-x1)
m=(-2-7)/(-8+8)
m=(-9)/0
m = undefined slope or no slope
x = -8
That expression is the expected value of your winnings, or "the average amount you will win (or lose) per game in the long run".
Answer:
0.3898 = 38.98% probability that there will be 4 failures
Step-by-step explanation:
A sequence of Bernoulli trials forms the binomial probability distribution.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Let the probability of success on a Bernoulli trial be 0.26.
This means that 
a. In five Bernoulli trials, what is the probability that there will be 4 failures?
Five trials means that 
4 failures, so 1 success, and we have to find P(X = 1).
0.3898 = 38.98% probability that there will be 4 failures
The filling rate is 2/5=0.4 gallons per second. So the appropriate equation is A.
