The probabilities for each case are:
a) P = 0.012b) P = 0.937How to get the probability?
There are 8 reservations for passengers that may go or not, such that the probability of arriving to the flight is P = 0.42, and the probability of not arriving is Q = 0.58
a) There will be overbooking if 7 or more passengers go to the flight, the probability that the 8 attend is:
P(8) = (0.42)^8
The probability that 7 attend is:
P(7) = 8*(0.42)^7*(0.58)
(where the factor 8 is because there are 8 permutations)
The total probability is:
P = P(8) + P(7) = 0.012
b) Will be empty seats if less than 6 people go.
The probability that exactly 6 of these people go to the flight is:
P(6) = (28)*(0.42)^6*(0.58)^2
Where there are 28 permutations, that is why we used that factor.
Then, the probability of having empty seats is:
P = 1 - P(6) - P(7) - P(8) = 0.937

Which hyperbola has one focus point in common with the hyperbola (y+11)^2/(15^2)-(x-7)^2/(8^2)=1
Answer:
3 &4
Step-by-step explanation:
The hyperbola with one focus point in common with the given hyperbola is:
[(y + 11)² / 10²] - [(x - 7)² / 15²] = 1
Which hyperbola has one focus point in common with the given hyperbola?To find a hyperbola that shares one focus point with the given hyperbola, we need to find another hyperbola with the same focus point but different characteristics (e.g., eccentricity or axis length).
The equation of the given hyperbola is:
[(y + 11)² / 15²] - [(x - 7)² / 8²] = 1
The general equation of a hyperbola with its center at (h, k) is:
[(y - k)² / a²] - [(x - h)² / b²] = 1
The center (h, k) of the given hyperbola is (7, -11).
To share one focus point, we need to keep the center at (7, -11) but change the values of a and b. The eccentricity of a hyperbola is defined as e = c / a, where c is the distance from the center to the focus.
Let's assume the new hyperbola has an eccentricity different from the given hyperbola. We'll keep the same value of c and change the value of a to get a different eccentricity.
Let's say the new hyperbola has a value of a' = 10. Since the eccentricity is different, the value of b' will change accordingly. Let's calculate b' using the eccentricity formula:
e = c / a'
15 / 10 = 1.5
Now, we can find b' using the eccentricity:
e = c / a' = c / 10
c = e * a' = 1.5 * 10 = 15
Now, we have the center (7, -11), the value of a' = 10, and the value of c = 15. The equation of the new hyperbola with one focus point in common is:
[(y + 11)² / 10²] - [(x - 7)² / 15²] = 1

Which of the following properties are true for rigid transformations?
i. Increases or decreases the size of the figure
ii. Moves the location of the figure.
iii. Changes the shape of the figure
O ii only
O i and ii
O ii and in
O i, ii, and in
Answer:
The first choice is correct. ii only.
Step-by-step explanation:
A rigid transformation changes the location of the shape without changing its size. There are three basic rigid transformations: reflections, rotations, and translations.
We are given these properties:
i. Increases or decreases the size of the figure
ii. Moves the location of the figure.
iii. Changes the shape of the figure.
Let's analyze each choice below:
O ii only . This is true. The other two properties are non-rigid transformations. Correct
O i and ii . This is not true. Increasing or decreasing the size of the figure is a non-rigid transformation. Incorrect.
O ii and iii. Changing the shape of the figure is a non-rigid transformation. Incorrect.
O i, ii, and iii. Properties i and iii are non-rigid transformation. Incorrect.

what is the m∠q ?????????????????????? help i taking a test and imma get beat if i fail
Answer:
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
this is an isosceles triangle, which mean that PRQ and PQR are equal.
all sides of a triangle equal 180.
using this, you can make the following equation:
x + (2x + 15) + (2x + 15) = 180
combine like terms
5x + 30 = 180
subtract 30 from both sides
5x = 150
divide both sides by 5
x = 30

3¹³ [3⁴ - 3² + 1] = [ ] x 73
3¹³ [81 - 9 + 1] = [ ] x 73
