Using the binomial distribution, there is a 0.0874 = 8.74% probability that not enough seats will be available.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
For this problem, the values of the parameters are given by:
n = 15, p = 0.85.
The probability that not enough seats will be available is P(X = 15), as the only outcome in which not enough seats will be available is when all 15 people who bought the ticket show up, hence:
0.0874 = 8.74% probability that not enough seats will be available.

Answer:
x = ±i sqrt(3/2)
Step-by-step explanation:
2x^2+7 = 4
Subtract 7 from each side
2x^2+7-7 = 4-7
2x^2 = -3
Divide by 2 on each side
2x^2/2 = -3/2
x^2 = -3/2
There is no real solution, only imaginary solutions
Taking the square root of each side
sqrt(x^2) = sqrt(-3/2)
x = ±i sqrt(3/2)

Answer
1.994g
Step-by-step explanation:
y=300(-9.6)^10
this is just a guess.
3/4x + 5 - 1/2x = 3
3/4x - 1/2x = 3 - 5
3/4x - 2/4x = -2
1/4x = -2
x = -2 / (1/4)
x = -2 * 4/1
x = -8 <==
