// Returns an array C[1..n] of the number of coins of each value, where
// the sum from 1 to n of C[i]*A[i] will equal t.
Greedy-Coins( t, A )
Define array C as an array of length n with all values zero for i = 1 to n
C[i] = t / A[i] // Note use INTEGER arithmetic here
t = C[i] mod A[i] // Note using integer modulo here to get the remainder
end fo ... ro
return C
An easy counterexample would be to use V = ( 5, 3, 1 ), and t= 9. The greedy algorithm will return values ( 1, 0, 4), but a little intuition shows that the array ( 0, 3, 0 ) will use fewer coins.
c) If we consider the array A = ( kn-1, kn-2, ..., k0), and k >0, then we can see that for any k < (n-1), there will be at most (k-1) coins of that value; if there had been sufficient \"value\" remaining to select k coins o that value, the greedy algorithm would have selected one more coin of the next coin up. Another way to look at this is that for any selection by the greedy algorithm from ki ... k0, the value MUST be less than ki+1, since ki+1 is by definition a multiple of k.

Let An = { a1, a2, ..., an } be a finite set of distinct cointypes (e.g., a1= 50 cents, a2= 25 cents, a3= 10 cents etc.). We assume each ai is an integer and that a1 > a2 > ... > an. Each type is available in unlimited quantity. The coin-changing problem is to make up an exact amount C using a minimum total number of coins. C is an integer > 0.
(a) Explain that if an != 1 then there exists a finite set of coin types and a C for which there is no solution to the coin-changing problem.
(b) When an = 1 a greedy solution to the problem will make a change by using the coin types in the order a1, a2, ..., an. When coin type ai is being considered, as many coins of this type as possible will be given. Write an algorithm based on this strategy.

Fe-59 concentrates in the spleen with a biological half life of approximately 600 days, and an effective half life of approximately 42 days.
Define half life?
The half-life of a reaction is the time required for the reactant concentration to decrease to one-half its initial value.Half life is the time that it takes for half of the original value of some amount of a radioactive element to decay. This also implies that one half life is the time that it takes for the activity of a source to fall to half its original value.An interesting and useful aspect of radioactive decay is half-life, which is the amount of time it takes for one-half of a radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.The units of half-life are time. The half-life is the length of time that it takes for half of an initial sample to undergo a change. Usually this is the radio-active decay of a specific atomic weight of an element. For example, the half-life of Uranium-238 is 4.46 billion years.To learn more about half life refers to:

question content area top part 1 what is the difference between an observational study and an experiment?
The difference is that in an observational study, the researchers do not control treatment, and in an experiment, they do.
An experiment is what?An experiment is a method used to verify or disprove a theory, as well as to determine something's effectiveness or likelihood.
An experiment vs an observational research differs fundamentally in that:
Members of a sample are measured or surveyed during an observational study without any attempt to manipulate them.
In an experiment, decisions are made under controlled conditions, subjects are divided into groups, and one group is given therapy while the other is left untreated. The main distinction between well-executed observational studies and experimental designs is that the replies of participants are unaffected, whereas in experiments, at least some participants are subjected to a treatment condition at random.
As a result, the researchers in an experiment control the therapy, but they do not in an observational study.

find the angles between the planes in exercises 47 and 48. 47. x y = 1, 2x y - 2z = 2
47.) The angle between the plane is 0 degrees.
48.) The angle between the plane is 180 degrees.
What is the angle between the plane?
To find the angle between two planes, we need to find the normal vectors of each plane and then find the cosine of the angle between the normal vectors using the dot product.
First, let's find the normal vectors for the two planes:
Plane 1: x + y = 1
The normal vector for this plane can be found by taking the coefficients of x, y, and z and forming a vector:
n1 = ⟨1, 1, 0⟩
Plane 2: 2x + y - 2z = 2
The normal vector for this plane can be found in the same way:
n2 = ⟨2, 1, -2⟩
Next, we will find the cosine of the angle between the normal vectors using the dot product:
cosθ = (n1 • n2) / (|n1| * |n2|)
where |n1| and |n2| are the magnitudes of the normal vectors.
Calculating the dot product and magnitudes:
n1 • n2 = 1 * 2 + 1 * 1 + 0 * -2 = 3
|n1| = sqrt(1^2 + 1^2 + 0^2) = sqrt(2)
|n2| = sqrt(2^2 + 1^2 + (-2)^2) = sqrt(9)
Substituting into the formula:
cosθ = 3 / (sqrt(2) * sqrt(9)) = 3 / (3) = 1
Since cosθ = 1, θ = 0, so the angle between the two planes is 0 degrees or a coincident plane.
Next, let's find the normal vectors for the two planes:
Plane 1: 5x + y - z = 10
The normal vector for this plane can be found by taking the coefficients of x, y, and z and forming a vector:
n1 = ⟨5, 1, -1⟩
Plane 2: x - 2y + 3z = -1
The normal vector for this plane can be found in the same way:
n2 = ⟨1, -2, 3⟩
Next, we will find the cosine of the angle between the normal vectors using the dot product:
cosθ = (n1 • n2) / (|n1| * |n2|)
Calculating the dot product and magnitudes:
n1 • n2 = 5 * 1 + 1 * (-2) + -1 * 3 = -3
|n1| = sqrt(5^2 + 1^2 + (-1)^2) = sqrt(27)
|n2| = sqrt(1^2 + (-2)^2 + 3^2) = sqrt(14)
Substituting into the formula:
cosθ = -3 / (sqrt(27) * sqrt(14)) = -3 / (3 * sqrt(2)) = -sqrt(2) / sqrt(2) = -1
Since cosθ = -1, θ = 180 degrees, so the angle between the two planes is 180 degrees, or perpendicular.
Hence,
47.) The angle between the plane is 0 degrees.
48.) The angle between the plane is 180 degrees.

14x + 5y = 975
10x + 4y = 750
small ad: $
full-page ad: $
On solving the linear equations 14x + 5y = 975 and 10x + 4y = 750, the price for small ad and full page ad is obtained as $25 and $125 respectively.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The two linear equations given are -
14x + 5y = 975 .... (1)
10x + 4y = 750 .... (2)
Here, x represents the price of small ad and y represents the price of a full-page ad.
To get the value of x and y solve the system of linear equations -
Multiply equation (1) by 4 and (2) by 5 -
4 (14x + 5y) = 4 × 975
56x + 20y = 3900 .... (3)
5 (10x + 4y) = 5 × 750
50x + 20y = 3750 .... (4)
Subtract equation (4) from (3) -
56x + 20y - (50x + 20y) = 3900 - 3750
56x + 20y - 50x - 20y = 3900 - 3750
6x = 150
x = 150/6
x = 25
Substitute the value of x in equation (1) -
14(25) + 5y = 975
350 + 5y = 975
5y = 975 - 350
5y = 625
y = 625/5
y = 125
So , the prices of small ad is $25 and prices of full-page ad is $125.
Therefore, the values for x and y are $25 and $125 respectively.

tape timer creates dots at a rate of 28 hz, what time interval in seconds does 3 successive dots represent?
Hz (Hertz) is a unit of frequency, which measures the number of events or occurrences of a certain phenomenon per second. In this case, the tape timer creates 28 dots per second, which means that the frequency of dot creation is 28 Hz.
To find the time interval between 3 successive dots, we need to calculate the time it takes for the tape timer to create 3 dots. This can be done by dividing the total time by the number of dots created.
Since the tape timer creates 28 dots per second, the time interval between 3 dots can be calculated as follows:
Time interval = 1 second / 28 dots = 1/28 seconds
So, the time interval between 3 successive dots created by the tape timer is 1/28 seconds, which is the amount of time that elapses between the creation of each dot.

The 95% confidence interval for the mean number of shoes owned by female students is (95.58, 195.14).
Calculate the sample mean:
Total number of shoes = 45+31+3125+62+15+29+27+28+35+18+55+18+39+28+35+44+18+10+55+50+40+38+22+16 = 3634
Sample mean = 3634/25 = 145.36
Calculate the standard deviation:
Standard deviation = √[(45-145.36)² + (31-145.36)² + (3125-145.36)² + … + (16-145.36)²]/24 = 586.33
Calculate the margin of error:
Margin of error = 1.96∗586.33/√25 = 49.78
Calculate the 95% confidence interval:
Lower bound = 145.36 - 49.78 = 95.58
Upper bound = 145.36 + 49.78 = 195.14
Since the sample mean is not an integer, we must round the lower and upper bounds to the nearest integer, which gives us (29.73, 40.27) as the 95% confidence interval for the mean number of shoes owned by female students.

The probability P that all the students with A’s and B’s are female and all the students with C’s and D’s are male is 0.0000907 or 0.00907%.
To determine the probability P, we can use the formula for combinations:
P = (number of ways to select A's and B's from the females) * (number of ways to select C's and D's from the males) / (number of ways to assign grades to all students)
Let's first find the number of ways to select A's and B's from the females:
There are 2 ways to select 2 A's from 7 females.
There are 7 choose 5 ways to select 5 B's from 7 females, which is 21.
So, there are 2 * 21 = 42 ways to select A's and B's from the females.
Next, let's find the number of ways to select C's and D's from the males:
There are 8 ways to select 8 C's from 11 males.
There are 11 choose 3 ways to select 3 D's from 11 males, which is 165.
So, there are 8 * 165 = 1320 ways to select C's and D's from the males.
Finally, let's find the number of ways to assign grades to all students:
There are 18 choose 2 ways to select 2 A's from 18 students, which is 153.
There are 18 choose 5 ways to select 5 B's from 18 students, which is 18564.
So, there are 153 * 18564 = 2827672 ways to assign grades to all students.
Putting it all together, the probability P is:
P = (42) * (1320) / (2827672) = 0.0000907
Therefore, the probability P that all the students with A’s and B’s are female and all the students with C’s and D’s are male is 0.0000907 or 0.00907%.

How can you use a protractor to prove that AB and CD are parallel?
How can you use paper folding to prove that AB and CD are parallel?
Lines AB and CD are parallel to each other because the lines make the same angle as the transversal line.
What are parallel lines?When the distance between the lines is constant then the lines are called parallel lines. The lines do not intersect when they are separated from each other. And the slope of the lines is equal.
Let the transversal line be EF to line AB and CD.
Line AB and line CD make the same angle as the transversal line. Then we can say that the lines AB and CD are parallel to each other.
The diagram is given below.

3 (q − 7) = 27
EXPLAIN PLEASE AND TYSM
Answer: q = 16
Step-by-step explanation:
When given the equation 3(q - 7) = 27, you would solve for the variable.
The variable in this equation is q, so we need to isolate the variable.
Solving process:
3(q - 7) = 27
lets distribute, due to the orders of PEMDAS.
PEMDAS stands for: Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
3(q - 7) = 27
distributing is multiplying the number correlated outside of the parenthesis with the inside components.
3q - 21 = 27
lets add 21 to both sides
3q = 48
now lets divide by 3 (we are trying to get q by itself)
q = 16
----
To check if your solution is correct, you replace the value (16) of the variable (q) within the original equation:
3 (16 − 7) = 27
Following PEMDAS you get:
3(9) = 27
27 = 27 (meaning that the solution is correct)

y^2(4-y^2) critical points
The critical values of the given function are 0, +2, and -2.
According to the question
Given function f(x) = y^2(4-y^2)
Setting the partial derivatives of the function y2(4-y2) to zero and solving for y will reveal where the function's crucial points are.
The partial derivatives of y^2(4-y^2) with respect to y are:
⇒ d/dy (y^2) = 2y
⇒ d/dy (4-y^2) = -2y
⇒ d/dy (y^2(4-y^2)) = 2y(-2y) + 2(y^2)
⇒ -4y^2 + 4y^2 = 0
Setting the partial derivative equal to zero:
-4y^2 + 4y^2 = 0
Solving for y:
y = 0 or y = ±2
The critical values are therefore y = 0 and y = 2. Using the second derivative test or by examining the behavior of the function close to these locations, these key points can be categorized as local minima, local maxima, or inflection points.

give f(x)= 3x + 5, describe how the graph of g compares with the graph of f
The function g(x) = (3x + 5) + 8 is a translation of 8 units upwards of f(x).
How does g(x) compares to f(x)?For a general function f(x), we define a vertical translation of N units as:
g(x) = f(x) + N
if N > 0, then the translation is upwards.
if N < 0, then the translation is downwards.
For a general function f(x), we define a horizontal translation of N units as:
g(x) = f(x) + N
if N > 0, then the translation is to the left.
if N < 0, then the translation is to the right.
Here we start at:
f(x) = 3x + 5
Function g(x) is:
g(x) = (3x + 5) + 8
g(x) = f(x) + 8
So this is a translation of 8 units up.

What is the light post's height?A lamp post is 45 feet away from where you are. You are standing at a 36" angle and are 5 feet tall as you stare up at the top of the light post.
tan 60 degrees is equal to 36/x sqrt(3),
36/x, and 36/(sqrt(3))*m. sqrt (3)
36/3 = 36 - h
h = 36 - 12
h = 24m
The distance between AB and CD is thus
60/(sqrt(3)) * 1.
