the degree of the polynomial is 8
The degree of a polynomial is determined by the largest power of an individual term or the sum of the exponents if more than 1 variable
3x² → is degree 2
6xy → is degree 2 ( sum of 1 and 1 )
- 10 → is degree 5
→ is degree 6
- 10x³ → is degree 8 ( sum of 3 and 5 )
the term with largest power is - 10x³
The degree of the polynomial is 8
We have 19 available seats, and 21 reservations.
Of the 21 reservations, 10 are sure, so we have 10 out of the 19 seats that are surely occupied.
Then, we have 9 seats for 11 reservations, each one with 44% chance of being occupied.
We have to calculate the probability that the plane is overbooked. This means that more than 9 of the reservations arrive.
This can be modelled as a binomial distirbution with n = 11 and p = 0.44, representing the 44% chance.
Then, we have to calculate P(x > 9).
This can be calculated as:
and each of the terms can be calculated as:
Then:
We have a probability of 0.18% of being overbooked (P = 0.0018).
If we want to calculate the probability of having empty seats, we need to calculate P(x<9), meaning that less than 9 of the reservations arrive.
We can express this as:
We have to calculate P(x=9) as we already have calculated the other two terms:
Finally, we can calculate:
There is a probability of 0.9875 that there is one or more empty seats.
Answer:
There is a probability of 0.0018 of being overbooked.
There is a probability of 0.9875 of having at least one empty seat.
Answer:
X + 2 19
Step-by-step explanation:
a number ur going to represent with a variable x and increased by 2 means + 2 so x + 2 and when it say greater than or equal to remember that it always opens to the lager number or x + 2 and has a line underneath to represent the or equal to.
