Answer:
Then the probability that 14 of the 19 voters will prefer Candidate A is approximately 0.1928 or 19.28%
Step-by-step explanation:
We can define X the random variable of interest "number of voters that will prefer Candidate A", since we have a sample size given and a probability of success we can use the binomial distribution to model the random variable. And on this case we can assume the following distribution:
The probability mass function for the Binomial distribution is given by:
Where (nCx) means combinatory and it's given by this formula:
For this problem we want to find this probability:

And usign the probability mass function defined before we got:
Then the probability that 14 of the 19 voters will prefer Candidate A is approximately 0.1928 or 19.28%
The answer is 9.05538513814
Answer:
r = -9
Step-by-step explanation:
use the slope formula:
(2-0) / (r-3) = -1 /6
cross-multiply:
-1(r - 3) = 2(6)
-r + 3 = 12
-r = 9
r = -9
