Answer:
Option 4 (±1, ±1/3, ±3, ±9) is the correct option.
Step-by-step explanation:
The given expression is
We have to find the possible rational zeros for the function.
So by the rational zero theorem factors will be
=±(Factors of constant term 9)/±factors of coefficient of
=±(Factors of 9)/±(Factors of 3)
=±(1, 3, 9)/±(1, 3)
=±(1, 3, 9, 1/3)
So option 4 is the correct answer.
Answer:
a) 0.0156
b) 0.4219
c) 0.1406
Step-by-step explanation:
We are given the following information:
We treat adult having type O+ blood as a success.
P(Adult have type O+ blood) = 0.25
Then the number of adults follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 3
a) All three are type O+
b) None of them is type O+
c) Two out of the three are type O
