Thus , probability of very last passenger getting seat comes out to be
P = 0.5 .
What is the process of probability?
Mathematics' field of probability deals with numerical representations of the possibility that an event will take place or that a statement is true. An event's probability is a number between 0 and 1, with 1 generally denoting certainty and 0 generally denoting impossibility.
Here,
If everyone chose at random, you would only have a 1/100 chance of receiving your own seat on a plane with 100 seats. However, in the context of this riddle, each participant does not make a random selection; rather, they only do so if all available seats have been occupied.
This indicates that half of the scenarios will resolve themselves (i.e., someone takes the mystery ticket holder's assigned seat allowing every subsequent passenger to take their assigned seat), while the other half will not resolve themselves and you will be seated in the incorrect location, making the probability of any plane occupancy equal to half.
Thus , probability of very last passenger getting seat comes out to be P = 0.5 .

in a circle of radius 3.4 cm, what is the length of the arc opposite a central angle that measures 46 degrees?
The length of the arc opposite a central angle that measures 46 degrees is 2.72 cm.
What is circle?
The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value.
in a circle of radius 3.4 cm
central angle that measures 46 degrees
length of arc = (46/360) * 2π*3.4
=2.72cm
Hence the length of the arc opposite a central angle that measures 46 degrees is 2.72 cm

Wendell’s Donut Shoppe is investigating the purchase of a new $18,600 donut-making machine. The new machine would permit the company to reduce the amount of part-time help needed, at a cost savings of $3,800 per year. In addition, the new machine would allow the company to produce one new style of donut, resulting in the sale of 1,000 dozen more donuts each year. The company realizes a contribution margin of $1.20 per dozen donuts sold. The new machine would have a six-year useful life.
Click here to view Exhibit 13B-1 and Exhibit 13B-2, to determine the appropriate discount factor(s) using tables.
Required:
1. What would be the total annual cash inflows associated with the new machine for capital budgeting purposes?
2. What discount factor should be used to compute the new machine’s internal rate of return? (Round your answers to 3 decimal places.)
3. What is the new machine’s internal rate of return to the nearest whole percent?
4. In addition to the data given previously, assume that the machine will have a $9,125 salvage value at the end of six
years. Under these conditions, what is the internal rate of return to the nearest whole percent?
As per the question, Total Annual Cash Inflows = 5000, Discount Factor = 3.72 and New Machine's internal rate of return = 16%
Note: The query is not complete and does not contain the necessary information for part 4. It is impossible to fully answer this question without the exhibits stated in the questions. Up until part 3, we will be solving it.
1) The entire annual cash inflows must be calculated for this, and the formula is given below:
Total annual cash inflows are equal to the annual savings from part-time labor plus the additional contribution margin from anticipated sales.
Annual Cash Inflows Total = 3800 + ( 1000 x 1.20)
= 3800 + 1200
= 5000
2. Formula for figuring up the discount percentage:
Discount Factor = New Machine Price/Annual Cash Flow
New machine cost is 18600 USD.
Annual inflow of cash = 5000
Discount Factor is equal to 18600/5000.
Discount Ratio is 3.72.
3. The examples, which are absent from this question, show that the discount factor for six years is roughly closest to 16%, hence the internal rate of return for the new machine is equal to 16%.
Note, without the exhibits indicated in the questions, the question is insufficient and cannot be utilized in Part 4. It cannot be solved any further.

The Equation for parallel line is: y= 4x - 13
The Equation for perpendicular line is: y= 1/4 x + 2
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
The passing point is (4, 3).
Now, the slope of given line
= Rise / Run
= 4 / 1
= 4
So, the slope for parallel line is 4 and for perpendicular line is -1/4.
Now, the line passes through (4, 3)
For parallel line
y= 4x+ b
3 = 4(4)+ b
3- 16 = b
b= -13
So, Equation for parallel line is: y= 4x - 13
For Perpendicular line
y= 1/4 x+ b
3 = 1/4(4)+ b
3- 1 = b
b= 2
So, Equation for Perpendicular line is: y= 1/4 x + 2

Answer:
Step-by-step explanation:
The required probability is 0.75 that a student visited the athletic complex regularly, given that he or she tried out for a sport.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
To find the probability that a student visited the athletic complex regularly, given that he or she tried out for a sport. This is known as the conditional probability of visiting the athletic complex regularly, given that the student tried out for a sport.
The formula for calculating conditional probability is:
P(A|B) = P(A and B) / P(B)
In this case, A is the event "visited the athletic complex regularly" and B is the event "tried out for a sport."
Substituting the given probabilities into the formula, we get:
P(A|B) = P(A and B) / P(B)
= 0.12 / 0.16

A vine called the mile-a-minute weed is known for growing at a very fast rate. It can grow up to 0.5 ft per day. How fast in inches per hour can the mile-a-minute weed grow up to? Show your work using the correct conversion factors.
Answer: 0.25 inches per hour.
Step-by-step explanation:
The mile-a-minute weed can grow up to 0.5 ft per day. To convert this to inches per hour, we need to convert the distance from feet to inches and the time from days to hours.
There are 12 inches in 1 foot, so the mile-a-minute weed can grow up to 0.5 x 12 = <<0.5*12=6>>6 inches per day.
There are 24 hours in 1 day, so the mile-a-minute weed can grow up to 6 / 24 = <<6/24=0.25>>0.25 inches per hour.
Therefore, the mile-a-minute weed can grow up to 0.25 inches per hour.
Here's the complete solution using the correct conversion factors:
1 ft = 12 inches
1 day = 24 hours
0.5 ft/day * (12 inches/1 ft) / (24 hours/1 day) = 0.25 inches/hour

What do you mean by equation of line?
A line equation is an algebraic representation of a set of points that together form a line in a coordinate system. A number of points that together form a line of axes, represented as a set of variables x,y, form an algebraic equation called the line equation.
Given passing points of line (-2,5) and (2,-3)
Equation of line having two passing points (a,b) and (c,d) is
y - b = [tex]\frac{d-b}{c-a}[/tex] (x - a)
So, equation of line having passing point (-2,5) and (2,-3) is
y - 5 = [tex]\frac{-3-5}{2+2}[/tex] (x + 2)
y - 5 = -2(x + 2)
y - 5 = -2x - 4
2x + y - 5 + 4 = 0
2x + y - 1 = 0
Therefore, equation of line having passing point (-2,5) and (2,-3) is y − 5 = −2(x + 2).

there are 14 members in a club: in the club, 4 are woman. how many ways are there to choose 10 member committess if atleast two of the commitee members must be woman
Answer:
a lot
960
Step-by-step explanation:
Since there are 4 woman in total, there are 14-4=10 men.
Part 1
They can choose either 2 women, 3 women, or 4 woman.
If they choose 2 out of the 4 woman, they can have 6 different combinations.
4!/(2!(4-2)!)
=24/(2(2!))
=24/4=6
There are 8 remaining men to be chosen on the committee (because 10-2=8).
There are 10 total men and 8 men need to be chosen out of them, so the number of combinations for men is given below.
10!/(8!(10-8)!)
=10!/(8!(2!))
Instead of multiplying out 1x2x3x4x5x6x7x8x9x10 to find 10!, we can divide 8! from both the numerator and denominator to simplify it. This leaves the numerator with 9x10, which is 90, and the denominator with 2!, which is just 2.
90/2=45
Now we need to multiply 45 (number of combinations to choose 8 men from 10 men) and 6 (number of combinations to choose 2 women from 4 woman).
45x6=270 combinations if 2 woman are chosen
Part 2
Next we need to find out how many combinations there are if they choose 3 women for the committee.
If they choose 3 out of the 4 woman, they can have 4 different combinations.
4!/(3!(4-3)!)
=24/(6(1!))
=24/6=4
There are 7 remaining men to be chosen on the committee (because 10-3=7).
There are 10 total men and 7 men need to be chosen out of them, so the number of combinations for men is given below.
10!/(7!(10-7)!)
=10!/(7!(3!))
Instead of multiplying out 1x2x3x4x5x6x7x8x9x10 to find 10!, we can divide 7! from both the numerator and denominator to simplify it. This leaves the numerator with 8x9x10, which is 720, and the denominator with 3!, which is 6.
720/6=120
Now we need to multiply 120 (number of combinations to choose 7 men from 10 men) and 4 (number of combinations to choose 3 women from 4 woman).
120x4=480 total combinations if 3 women are chosen
Part 3
If 4 women out of 4 women are chosen for the committee, then obviously, there will only be 1 combination for that, since all the women will be chosen.
This leaves us with 10-4=6 spots for men in the committee.
There are 10 total men and 6 men need to be chosen out of them, so the number of combinations for men is given below.
10!/(6!(10-6)!)
=10!/(6!(4!))
Instead of multiplying out 1x2x3x4x5x6x7x8x9x10 to find 10!, we can divide 6! from both the numerator and denominator to simplify it. This leaves the numerator with 7x8x9x10, which is 5040, and the denominator with 4!, which is 24.
5040/24=210
Now we need to multiply 210 (number of combinations to choose 6 men from 10 men) and 1 (number of combinations to choose 4 women from 4 woman).
210x1=210 total combinations if 3 women are chosen
Part 4
Finally, we need to add all the final answers from the previous parts.
270+480+210=960 total combinations if at least 2 women were chosen for the committee

A panel in one of the hallways of Emilio’s school is rectangular with an area of 44.52 square feet. If the panel is 21 feet long, how wide is it?
Answer:
Step-by-step explanation:
So hi this is saveon and this is how you do the question so first you divide 44.52 by 21 you will get 2.12 feet and that is your answer
It is 2.12 feet wide.
What is rectangle ?
A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.
An equiangular quadrilateral is another name for a rectangle. The reason for this is that a rectangle is a quadrilateral form (4-sided shape) with parallel sides that are equal to one another and four corners with 90o angles. A rectangle can also be referred to as an equiangular quadrilateral because all of the angles are 90 degrees.
Rectangle area = width * height
44.52 / 21
= 2.12 feet

Determine whether the function f(x)=-9-x^5+2x^3 is even, odd, or neiter.
f( x ) is an odd function
What is even or odd function ?The symmetry of a function is described using the terms even and odd. On a graph, an even function is symmetric about the y-axis. An odd function has symmetric behavior around a graph's origin (0, 0).
According to the given information
We are given with the function
f( x ) = [tex]-9-x^{5} + 2x^{3}[/tex]
For checking that the function is even or odd
Case 1
put -x in place of x
f ( -x ) = [tex]-9-(-x)^{5} + 2(-x)^{3}[/tex]
f ( -x ) = [tex]-9+x^{5} -2x^{3}[/tex]
f(x) ≠ f (-x)
Hence it is not an even function
So
f(-x) = -f(x)
hence
f( x ) is an odd function

A chemical equation is the symbolic illustration of a chemical response in the shape of symbols and chemical formulas. The reactant entities are given at the left-hand side and the product entities at the proper-hand facet with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the goods to expose the route of the response. The chemical formulation can be symbolic, structural (pictorial diagrams), or intermixed. The equal holds for the whole electric-powered rate, as stated by way of the rate conservation regulation. An equation adhering to these necessities is said to be balanced.
A chemical equation is balanced by assigning appropriate values to the stoichiometric coefficients. simple equations can be balanced by using inspection, that is, by using trial and blunder. another method entails solving a gadget of linear equations.
Balanced equations are generally written with the smallest natural-wide variety coefficients. but on occasion, it can be high quality to just accept a fractional coefficient if it simplifies the opposite coefficients.

The number of members for an e-commerce company was 1,700 in the year that the company started and has increased by 10% per year since then. The exponential function of the number of members, m(t), in terms of t, the number of years since the year the company started, can be described by m(t) = 1700(1. 10)t. What is m(5) and its interpretation in the context of the problem?.
M(5) = 2737.867; After 5 years, there are approximately 2,737 members in the company
What does M(5) mean and how should it be interpreted in relation to the issue?
In this case, we know that the exponential function M(t) = 1700*(1.10)t denotes the number of members the company had t years after its founding.
Then, M(5) will stand for the number of members who joined the company five years after its founding. To determine this value, all we have to do is substitute the number five for the variable t.
M(5) = 1700*(1.10)^5 = 2,737.867
Rounding to the nearest whole number, we obtain 2,737, which indicates that there will be roughly 2,737 members after 5 years.
Consequently, the second choice is the right one:
"M(5) = 2737.867; There are about 2,737 members in the company after 5 years."

What will happen to the original shape of the scale factor is equal to 1?
If the scale factor is equal to one, then there wont be any change in the original shape
The scale factor is defined as the ratio of the original size of the shape to the new size of the shape.
There are three types of scale factors will be there, greater than one, equal to one and between 0 and 1
When the scale factor is greater than 1, then the shape will enlarge
When the scale factor is equal to 1, there wont be any change in original shape
When the scale factor is between 0 and 1, the shape will decrease the size
Therefore, there wont be any change in original shape when scale factor equal to one
