Answer:
(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36
Answer:
1 thus b: is the Answer
Step-by-step explanation:
Simplify the following:
(3 (15 + 4)^2 + 2 (20 + 5)^2)^0
(3 (15 + 4)^2 + 2 (20 + 5)^2)^0 = 1:
Answer: 1
Answer:
(B) No. A binomial probability model applies to only two outcomes per trial.
Step-by-step explanation:
The binomial probability is the probability of having
sucesses on
repeated trials of an experiment that can only have two outcomes. This is why it is called the binomial probability.
Since in our problem there are three possible outcomes, the binomial probability cannot be used.
The correct answer is (B)
(B) No. A binomial probability model applies to only two outcomes per trial.
I think the answer is 6 since u multiply them
