For this case we have the following polynomial:
x2 + 6x + 8
We note that the polynomial can be rewritten as:
(x + 4) (x + 2)
Answer:

(x + 4)
option B

The given trinomial can be factored using factorization as

x²+6x+8
=x²+2x+4x+8
=x(x+2)+4(x+2)
=(x+2)(x+4)

Thus x+2 and x+4 are the factors of the given trinomial. From these we can see x+4 is listed in option B.

So the answer to this question is Option B

4. Solve the following inequality: 3y-1 less than 3

mylen [45]

3y - 1 < 3

Isolate the y. Treat the less than or equal like an equal sign.

Do the opposite of PEMDAS. First, add 1 to both sides

3y - 1 (+1) < 3 (+1)

3y < 4

Next, divide 3 from both sides

3y/3 < 4/3

y < 4/3

y < 4/3 is your answer

hope this helps

There are 30 balls numbered 1-30 in a bag. One is randomly selected 12 times. What is the probability of getting a prime number

Sliva [168]

Answer: The probability of getting a prime number exactly five times = 0.1908

Step-by-step explanation:

Prime numbers from 1 to 30 are 2,3,5,7,11, 13, 17, 19, 23, 29.

The probability of getting a prime number p= $\dfrac{10}{30}=\dfrac13$

Number of trials n = 12

Binomial probability formula:

$P(X=x) = \ ^nC_x p^x(1-p)^{n-x}$

, where x= number of successes

n= number of trials.

x = Number of successes

p= probability of getting one success.

The probability of getting a prime number exactly five times:

$P(X=5)=\ ^{12}C_5(\frac13)^5(1-\frac13)^{7}$

$=\frac{12!}{5!7!}(\frac1{243})(\frac{128}{2187})\\\\=0.1908$

Hence, the probability of getting a prime number exactly five times = 0.1908
