A.3
Step-by-step explanation:
Answer:
p(x) = (5x - 1) (x + 3)
Step-by-step explanation:
I apologize if I couldn't answer correctly, the question was a bit hard to understand because of the formatting.
Also I didn't see my answer in the list of answer choices but here it is:
if the polynomial has zeros at 0.2 and -3 the equation would have to be:
p(x)=(x-0.2)(x+3)
This is because plugging either of those numbers into the polynomial would cause it to equal 0.
(x-0.2) can be simplified by multiplying everything in the parenthesis by 5, getting rid of all of the decimals, making the final answer:
p(x) = (5x - 1) (x + 3)
7 times 30 is 210
answer: 30
The probability is 0.336.
To solve this, we need Binomial Probability equation for Repeated Trials.
P = nCr (p)^r (q)^(n-r)
where P = probability (unknown)
n = number of trials (8)
r = number of successes (1)
p = probability of success (.20)
q = probability of failure (0.80)
P = 8C1 (.20)^1 (.80)^7
= 0.336
