a tree is a connected and acyclic graph. how many edges must be included in any tree with 100 vertices?
99 many edges must be included in any tree with 100 vertices.
This is because, in a tree, there must be one fewer edge than vertices. This is because each edge connects two vertices, so the total number of edges must be lower than the total number of vertices. Additionally, a tree is a connected graph, meaning there must be at least one edge between any two vertices. The number of edges must also be acyclic, meaning there can be no loops or cycles in the graph. Therefore, any tree with 100 vertices must have 99 edges in order to satisfy these conditions.

What is parameter?
A parameter is a piece of information that an equation passes on. In terms of statistics, it means something different. In contrast to statistics, which only provide information about a small portion of the population, this value provides information about the entire population.
A parameter is constant because it was determined by surveying everyone (or everything). The average age of the students in your class, for instance, might be of interest to you. Maybe after asking everyone, you discovered that the average age was 25. Given that you polled the entire class, that qualifies as a parameter.

The event coordinator asks you to determine how many students participated in the track-and- field day. The total number of students in seventh and eighth grade combined is 595.
a) If 3/5 of the 595 students are seventh graders, and 5/8 of them participated in the competition, about how many seventh graders participated in the competition? Describe the process you used to find your answer. (2 points)
b) If 2/5 of the 595 students are eighth graders, and 7/8 of them participated in the competition, about how many eighth graders participated in the competition? Describe the process you used to find your answer. (2 points)
Answer:
Step-by-step explanation:
To determine who was closer to the state record, we need to compare the distances of the jumps to the state records. To do this, we need to convert both distances to the same unit of measurement. We can convert inches to feet by dividing by 12. 38 feet 11 2/3 inches is equal to 38 + 11 2/3/12 = 38 + 0.9583333 feet = 39.9583333 feet.
Now we can compare the distances to the state records. The eighth-grade record is 40.17 feet and Alex jumped 39.9583333 feet, so he was closer to the record. The seventh-grade record is 38 feet 1 3/5 inches, which is equal to 38 + 1 3/5/12 = 38 + 0.292 feet = 38.292 feet. Eric jumped 36.89 feet, so he was not as close to the record as Alex. Therefore, the eighth graders should be awarded 100 points.
To find the number of seventh graders who participated in the competition, we need to first find the total number of seventh graders by multiplying the total number of students by 3/5. 595 x 3/5 = 357. Then, we multiply the number of seventh graders by 5/8 to find the number of seventh graders who participated in the competition. 357 x 5/8 = 214.625, or about 215 seventh graders participated in the competition.
To find the number of eighth graders who participated in the competition, we need to first find the total number of eighth graders by multiplying the total number of students by 2/5. 595 x 2/5 = 238. Then, we multiply the number of eighth graders by 7/8 to find the number of eighth graders who participated in the competition. 238 x 7/8 = 205.75, or about 206 eighth graders participated in the competition.

The Green's function that solves the problem on a semicircular region is given by G(x, xo) = მ (x-xo)(cos(θ)sin(θ)).
What is Green's function?
Green's function is an important mathematical tool used to solve differential equations. It is defined as a solution to a homogeneous linear differential equation with a source, or delta, function as its input. Green's functions are also known as impulse response functions and can be used to describe the response of a system to an arbitrary input. Green's functions provide a way to solve differential equations without having to solve the entire equation all at once. They are particularly useful for solving equations with boundary conditions that are difficult to solve without the use of Green's functions. Green's functions can also be used to solve integral equations and provide a powerful tool for solving many physical problems.
The reflection method for finding a Green's function for a problem on a semicircular region can be used as follows. First, we solve the problem on the half-plane by finding a Green's function G(x, xo) that satisfies the boundary conditions given. Then, we reflect the solution across the boundary of the semicircle, namely T1 and T2, to obtain the Green's function on the entire semicircle.
The Green's function on the half-plane is given by G(x, xo) = მ (x-xo). Using this solution, we can reflect it across the boundary of the semicircle. For T1, the reflected solution is given by G(x, xo) = მ (x-xo)cos(θ), where θ is the angle between the normal vector to T1 and the vector from xo to x. For T2, the reflected solution is given by G(x, xo) = მ (x-xo)sin(θ), where θ is the angle between the normal vector to T2 and the vector from xo to x.
Therefore, the Green's function that solves the problem on a semicircular region is given by G(x, xo) = მ (x-xo)(cos(θ)sin(θ)).

The probability density function fr(r) of the distance from a uniformly randomly chosen point in the unit disk to the origin is r, and the cumulative distribution function Fr(r) is (r² / 2).
To find the probability density function (PDF) and cumulative distribution function (CDF) of the distance from a uniformly randomly chosen point in the unit disk to the origin, we can first find the area of the unit disk and the area of the annulus centered at the origin and bounded by two circles with radii r and r + dr. The PDF is then the ratio of the area of the annulus to the total area of the unit disk, and the CDF is the ratio of the area of the annulus to the total area of the unit disk up to radius r.
The area of the unit disk is simply the area of a circle with radius 1, which is pi. The area of the annulus centered at the origin and bounded by two circles with radii r and r + dr is equal to the difference between the areas of the two circles, which is pi(r + dr)² - pi(r²). Therefore, the PDF of r is:
fr(r) = [pi(r + dr)² - pi(r²)] / pi = r + dr²
The CDF of r is the sum of the PDFs up to radius r, which is:
Fr(r) = ∫fr(t)dt from 0 to r = ∫(t + dt²)dt from 0 to r = (r² / 2) + (r × dt) + (dt³ / 3)
We can take the limit as dt approaches 0 to get the final expression for the CDF:

Bond interest payments before and after taxes Charter Corp. issued 2,500 deben-
tures with a $1,000 par value and a 7% coupon rate.
a. What dollar amount of interest per bond can an investor expect to receive each
year from Charter?
b. What is Charter's total interest expense per year associated with this bond issue?
c. Assuming that Charter pays a 21% corporate tax, what is the company's net
after-tax interest cost associated with this bond issue?
Answer:
To answer these questions, we need to know the par value, coupon rate, and number of debentures issued by Charter Corp. Based on the information provided, Charter Corp. issued 2,500 debentures with a $1,000 par value and a 7% coupon rate.
a. The dollar amount of interest per bond that an investor can expect to receive each year from Charter is calculated by multiplying the par value by the coupon rate. In this case, the interest per bond would be $1,000 x 7% = $70.
b. The total interest expense per year associated with this bond issue can be calculated by multiplying the number of bonds by the interest per bond. In this case, the total interest expense would be 2,500 x $70 = $175,000.
c. The company's net after-tax interest cost associated with this bond issue can be calculated by multiplying the total interest expense by the corporate tax rate. In this case, the net after-tax interest cost would be $175,000 x 21% = $36,750.
There are 48 blue birds in a tree. There are 32 red burds in the tree. How many more bluebirds are there in the tree than red

Jayson has 2{1}/{2} months' worth of pay saved in his account. He has 1{1}/{4} months' worth of pay saved in cash. Altogether, how much money has Jayson saved?
(a) Sandy picked [tex]1\frac{1}{2}[/tex] more buckets than Keith .
(b) Jason have saved money for total of [tex]3\frac{3}{4}[/tex] months .
In the question ,,
Part(a) ,
it is given that
number of buckets of apples Keith picked is = [tex]2\frac{5}{6}[/tex] buckets ,
number of buckets of apples Sandy picked is = [tex]4\frac{1}{3}[/tex] buckets
number of more buckets picked by Sandy is = (buckets picked by Sandy) - (buckets picked by Keith) .
= [tex]4\frac{1}{3}[/tex] - [tex]2\frac{5}{6}[/tex]
= 13/3 - 17/6 = 3/2 = [tex]1\frac{1}{2}[/tex] buckets .
Part(b)
number of months that Jason saved money in account = [tex]2\frac{1}{2}[/tex] months
number of months that Jason saved money in cash = [tex]1\frac{1}{4}[/tex] months
total number of months for which money is saved is = [tex]2\frac{1}{2}[/tex] + [tex]1\frac{1}{4}[/tex]
Simplifying further ,
we get,
= 5/2 + 5/4
= 15/4
= [tex]3\frac{3}{4}[/tex] months .
Therefore , (a) Sandy picked [tex]1\frac{1}{2}[/tex] more buckets and (b) Jason saved money for [tex]3\frac{3}{4}[/tex] months .
The given question is incomplete , the complete question is
(a) Keith picked [tex]2\frac{5}{6}[/tex] buckets of apples and Sandy picked [tex]4\frac{1}{3}[/tex] buckets. How many more buckets of apples did sandy pick ?

all prime number greater than 2 are odd?
Answer:
Prime numbers are odd that are greater than 2. Prime numbers are numbers that are not divisible by anything. EXAMPLE: 33 is not prime because if you take 3 times 11 then you get 33.
Step-by-step explanation:
Find the dimensions of a rectangular box of maximum volume such that the sum of the lengths of its 12 edges is a constant c. (Let x, y, and z be the dimensions of the rectangular box.)
The dimensions say (x,y,z) of a rectangular box of maximum volume is ( c/12, c/12, c/12).
What is Dimensions by Derivatives ?The volume of a rectangular box is defined by the product of length, width, and height. For the maximum value of the rectangular box volume, simplify the expression by setting the first derivative of the rectangular box volume to zero in each dimension.
Let x, y, and z be the dimensions of the rectangular box. Since, the sum of the lengths of its 12 edges is a constant c. This implies
4x + 4y + 4z = c
=> x + y + z = c/4 --(1)
The volume of rectangular box = xyz
Consider xyz + lamda(x + y + z - c/4) where λ is Lagrange multiplier.
let f( x,y,z) = xyz + λ(x + y + z - c/4) --(*)
compute the partial derivatives of f( x,y,z) as
fx = yz + λ(1) = yz + λ
fy = xz + λ(1) = xz + λ
fz = xy + λ(1) = xy + λ
For critical points, set the partial derivatives equals to zero.
fx = yz + λ = 0
fy = xz + λ = 0
fz = xy + λ =0
=> xz = yz = xy = - λ
So, x = y = z
then, from equation (1) we get,
x + x + x = c/4
=> 3x = c/4 => x = c/12
thus, x = c/12, y = c/12, z = c/12
Thus, the dimensions of the rectangular box are x = y = z = c/12 or ( c/12, c/12, c/12) and
Maximum volume of rectangular box = xyz
= c³/1728

Write a MATLAB code for the following question:
Customers depart from a bookstore according to a Poisson process with the rate of 4 customers per hour. Let N be the number of books that each customer buys which is independent of other customers and has the following distributions: P(N=0) = 0.2; P(N=1) = 0.4; P(N=2) = 0.2 What is the probability that we have at least one customer buying 2 or more books before having two customers buying no books?
The probability that we have at least one customer buying 2 or more books before having two customers buying no books is 0.984.
Here is a possible MATLAB code to solve the problem:
%START
% Set the rate of the Poisson process
lambda = 4;
% Set the probabilities of N taking different values
p0 = 0.2;
p1 = 0.4;
p2 = 0.2;
% Compute the probability of having at least one customer buying 2 or more books
% before having two customers buying no books
prob = poisscdf(2-1, lambda*p0) - poisscdf(1-1, lambda*p0);
% Display the result
fprintf('Probability of having at least one customer buying 2 or more books before having two customers buying no books: %.4f\n', prob);
%END
This code uses the poisscdf function to compute the probability of having a certain number of events (customers buying 2 or more books or customers buying no books) in a given time period (one hour), assuming that the events occur according to a Poisson process with the given rate (4 customers per hour).
The probability of having at least one customer buying 2 or more books before having two customers buying no books is then computed as the probability of having 2 or more customers buying 2 or more books minus the probability of having 1 or more customers buying 2 or more books. The result is displayed using the fprintf function.
