Answer:
The lines don't intercept
Step-by-step explanation:
we have
isolate the variable y
Divide by 3 both sides
simplify
-----> equation A
Isolate the variable y
Divide by 6 both sides
simplify
-----> equation B
Compare equation A and equation B
The slopes are the same and the y-intercepts are different
Remember that
If two lines has the same slope, then the lines are parallel
therefore
In this problem line A and line B are parallel lines
The system of equations has no solution, because the lines don't intercept
Answer:
Step-by-step explanation:
Given that the probability that a person in the United States has type B+ blood is 13%.
Since four unrelated people in the United States are selected at random, we can say that each person is independent of the other to have B+ blood group.
Let X be the number of persons who have blood group B+ in the group of 4 persons.
X is Binomial with p = 0.13
a) P(X = 4) =
b) P(x =0) =
c)
d) All having B+ is unusual since probability is very negligible
