Answer:
We have a binomial probability distribution, in which:
P(X = 0) = 0.064
P(X = 1) = 0.288
P(X = 2) = 0.432
P(X = 3) = 0.216
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it is for domestic travel, or it is for international travel. Flights are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Let x be the number of requests among the next three requests received that are for domestic flights.
3 flights, and 60% are for domestic travel. This means that . The probabilities are given by:
The factor of the function will be (x - 1), (x - 2), and (x + 2). Then the roots of the function will be 1, 2, and negative 2.
<h3>What is a factorization?</h3>
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The function is given below.
f(x) = 4x³ - 4x² - 16x + 16
Then the factor of the function will be
f(x) = 4x²(x - 1) - 16(x - 1)
f(x) = 4(x - 1) (x² - 4)
f(x) = 4(x - 1) (x² - 2²)
f(x) = 4(x - 1)(x - 2)(x + 2)
Then the roots of the function will be
x = 1, 2, -2

Step-by-step explanation:
6:2:3:4
for every 6 pairs of wedges she owns 2 Stillettos, 3 sneakers and 4 sandals
18/6 =3
3*2 =6 stilettos
3*3 = 9 sneakers
3*4 =12 sandals
18 + 6 + 9 + 12 = 45 pairs of shoes
