Answer:
Result: 95040 foot/minute = 1080 mile/hour, so the answer is 95040
Answer:
15 + 3n
Triple the amount of evening which is “n” so it would “3n”
The morning amount would still be 15
Answer:
The probability that the student is going to pass the test is 0.0545
Step-by-step explanation:
The variable that says the number of correct questions follows a Binomial distribution, because there are n identical and independent events with a probability p of success and a probability 1-p of fail. So, the probability of get x questions correct is:

Where n is equal to 10 questions and p is the probability of get a correct answers, so p is equal to 1/2
Then, if the student pass the test with at least 8 questions correct, the probability P of that is:
P = P(8) + P(9) + P(10)

P = 0.0439 + 0.0097 + 0.0009
P = 0.0545
F(x) = 3x³ - 12x² - 15x
1) Factor Outside: 3x( x² - 4x - 5)
Factor Inside: 3x(x + 1)(x - 5)
2) Set Equal To 0:
3x = 0
x + 1 = 0
x - 5 = 0
3) Solve:
x = 0, -1, 5
