Answer:
$69
Step-by-step explanation:
25% = 0.25
17.25 ÷ 0.25 = 69
69 × 0.25 = 17.25
The original price of the hammer from the online retailer is $23.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Percentage is usually denoted by the symbol '%'.
Given that,
Discount percentage = 25%
Amount after the discount = $17.25
We have to find the original price of the hammer.
Let x be the original price of the hammer.
x - 25% of x = 17.25
x - 0.25x = 17.25
0.75x = 17.25
x = $23
Hence the original cost of the hammer is $23.

David's opportunity cost of producing 1 pound of watermelon is 4 pounds of zucchini, whereas Morgan's opportunity cost of producing 1 pound of watermelon is 3 pounds of zucchini. Because David has a higher opportunity cost of producing watermelon than Morgan, Morgan has a comparative advantage in the production of watermelon, and David has a comparative advantage in the production of zucchini.
What is opportunity cost?
Opportunity costs are the possible advantages that a person, investor, or company forgoes while deciding between two options. Opportunity costs are by definition invisible, making it simple to ignore them.
The best input combinations to achieve the highest level of output are displayed on the production potential frontier.
The individual who has a lower opportunity cost in output than another individual enjoys a comparative production advantage.
David's watermelon production -
54 units watermelon = 216 units zucchini
1 unit watermelon = 216/54 units zucchini
1 unit watermelon = 4 units zucchini
Morgan's watermelon production -
108 units watermelon = 324 units zucchini
1 unit watermelon = 324/108 units zucchini
1 unit watermelon = 3 units zucchini
Morgan has absolute advantage in production of Zucchini and Morgan has also absolute advantage in production of watermelon.

(i) Find an expression for the length of each side of the square bottom. (ii) Use the function to find the volume of a cage with a height of 18 inches. (iii) Use the remainder theorem to find the volume of a cage with a height of 15 inches
The remainder theorem can be used to determine the volume of a cage with a 15-inch height since b = 15, which results in a volume of 2160 inch3.
what is volume ?The size of an item in 3 directions is the area that is covered by its boundaries. The amount of room an object occupies in three aspects is measured by its height, which is given in cubic inches. A few of illustrations of cubic units are cm3 and in3. On the other perspective, an item's mass is used to measure what more matter it contains. The typical method to ascertain an object's mass is to weigh it, either in pounds or kilograms. Unlike the fundamental equations for the area of a rectangular box, which is length, breadth, and height, the primary equation for volumes is length, width, and height.
given
Height is listed as b and is 18 inches.
B = 18 s= b-3 (from I = 18 - 3 s = 15 as a result.
Therefore, volume
volume of a rectangle = l x b x h V= 18 x 15 x 15 = 4,050 inch3
3) Height = 15 then b = 15 b -15 = 0 if height = 15.
The remaining theorem's definition is:
To get a smaller polynomial and a remainder, we divide a polynomial P(x) by the factor (x - a). The polynomial does not have to contain the factor.

Therefore , the solution of the given problem of range comes out to be the range of the composite function f(g(h(x))) is [0, ∞).
Describe range.By calculating the variable's maximum observed value and subtracting its minimum observed value, the variable range is obtained (minimum). Potential range or finite difference bounds include different steel pricing and various designs. A procedure or action's breadth or scope insight into the maximum or expected range of a weapon's projectile. The number between the minimum and maximum of a list and set is known as its range. You can locate the area by lining up all the numbers.
Here,
The range of a function is the set of all possible output values. Let's consider each function separately:
f(x) = |x-3|
The absolute value of any number is always non-negative, so the range of f(x) is [0, ∞).
g(x) = -(x-4)²-3
The square of any real number is always non-negative, so the range of the function -(x-4)² is (-∞, 0]. Subtracting 3 from this range gives the range of g(x) as (-∞, -3].
h(x) = -7
The output of h(x) is always -7, so the range of h(x) is {-7} (a singleton set containing only the number -7).
Putting it all together, the range of the composite function f(g(h(x))) is [0, ∞).

Describe Triangles?A triangle is a closed geometric figure that is formed by connecting three straight line segments called sides. These sides meet at three points called vertices. Triangles are one of the simplest and most fundamental shapes in geometry and can be found in many natural and man-made objects.
Triangles can be classified into different types based on their sides and angles.
By sides:
Equilateral triangle: all three sides are equal in length.
Isosceles triangle: two sides are equal in length.
Scalene triangle: all three sides are different in length.
By angles:
Acute triangle: all three angles are acute (less than 90 degrees).
Right triangle: one angle is a right angle (exactly 90 degrees).
Obtuse triangle: one angle is an obtuse angle (greater than 90 degrees).
Triangles have many properties and are used in various fields such as architecture, engineering, physics, and mathematics. They are also commonly used in trigonometry to solve problems involving angles and distances.
We can use the property of similar triangles to solve this problem.
First, let's label the intersection point of FG and BC as point H. Also, let's label the length of CG as x.
Since FG is parallel to AC, we can use the property of similar triangles to find that triangles ABF and HBG are similar.
Therefore, we can set up the proportion:
AB/FB = HG/GB
Plugging in the given values, we get:

Calculate the mean, Variance and Standard deviation of the age of 12 student 16, 17, 18, 16/0.5, 17, 18, 19, 17, 17, 13, 17/½/2 and 16
The mean age of the 12 students is approximately 17.02 years, the variance is 37.41, and the standard deviation is approximately 6.117 years.
What is Statistic?The statistic is the study of mathematics that deals with relations between comprehensive data.
Here,
To calculate the mean, variance, and standard deviation of the ages of the 12 students, we first need to find the sum of the ages:
Sum = 16 + 17 + 18 + (16/0.5) + 17 + 18 + 19 + 17 + 17 + 13 + (17/2/2) + 16
= 16 + 17 + 18 + 32 + 17 + 18 + 19 + 17 + 17 + 13 + 4.25 + 16
= 204.25
Mean = Sum / Number of students = 204.25 / 12 ≈ 17.02 years
To calculate the variance, we need to subtract the mean from each age, square the differences, add up the squares, and divide by the number of students minus one:
Variance = [ (16 - 17.02)² + (17 - 17.02)² + ... + (16 - 17.02)² ] / (12 - 1)
= [ 0.16 + 1.96 + ... + 0.16 ] / 11
= 37.41
Finally, we can calculate the standard deviation by taking the square root of the variance:
Standard deviation = √(Variance) ≈ 6.117
Therefore, the mean age of the 12 students is approximately 17.02 years, the variance is 37.41, and the standard deviation is approximately 6.117 years.

Using third-order Newton's interpolating a polynomial the value of f(2) is (25ln(2))/9.
What is the value of f(2)To estimate the value of f(2) using a third-order Newton's interpolating polynomial with the given data points, we first need to calculate the divided differences. The divided differences are defined as:
f[xi] = f(xi) for i = 1, 2, 3
f[x1,x2] = (f[x2] - f[x1]) / (x2 - x1) = (ln(4) - ln(1)) / (4 - 1) = ln(4) / 3
f[x2,x3] = (f[x3] - f[x2]) / (x3 - x2) = (ln(6) - ln(4)) / (6 - 4) = ln(3) / 2
f[x1,x2,x3] = (f[x2,x3] - f[x1,x2]) / (x3 - x1) = ((ln(3) / 2) - (ln(4) / 3)) / (6 - 1) = -0.018
Using these divided differences, we can write the third-order Newton's interpolating polynomial as:
f(x) = f[x1] + f[x1,x2](x - x1) + f[x1,x2,x3](x - x1)(x - x2) + f[x1,x2,x3,x4](x - x1)(x - x2)(x - x3)
Substituting the values of the data points and the divided differences we calculated, we get:
f(x) = ln(1) + ln(4)/3 (x - 1) - 0.018 (x - 1)(x - 4)
Simplifying this expression, we get:
f(x) = ln(1) + (ln(4)/3)x - (11ln(2)/9) + (ln(2)/9)x^2
To estimate f(2), we plug in x = 2:
f(2) = ln(1) + (ln(4)/3)(2) - (11ln(2)/9) + (ln(2)/9)(2)^2
f(2) = 2ln(2) - (11ln(2)/9) + (ln(2)/9)(4)

The Law of Sines, also known as the Sine Rule, is a formula used to find unknown angles or sides of a triangle, given some combination of angle and side measurements. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle. Mathematically, the Law of Sines can be expressed as follows:
a/sin(A) = b/sin(B) = c/sin(C)
where a, b, and c are the lengths of the sides of the triangle, and A, B, and C are the angles opposite those sides, respectively.

10352 grade point averages must be obtained. The solution has been obtained by using the concept of sample size.
What is sample size?
The sample size is the number of observations utilised to derive estimates for a certain population. By taking a sample from the population, the sample size was established. Sampling is the practise of selecting a subset of the population to infer characteristics about the complete population.
We know that for 99% confidence, the z- score is 2.5758
So, using this we get
N = (z * σ/E)²
N = (2.5758 * 0.79/0.02)²
N = 10351.86
Hence, 10,352 grade point averages must be obtained so that the sample mean is within 0.2 of the population mean.

A person invested $13,000, part of the money, x, was placed in a stock that paid 9% annual interest. The rest of the money suffered a 5% loss. Express the total annual income from both investments, I, as a function of x.
The total annual income from both investment is
(14x -65000)/100
What is interest?Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
I = x× 9/100
I = 9x/100
(13000 - x) × 5/100
= (65000-5x)/100
therefore the total amount annual income
= 9x /100 - (65000-5x)/100
= (9x+5x-65000)/100
= (14x - 65000)/100
therefore the total annual income = (14x -65000)/100

In a case whereby a person invested $13,000, part of the money, x, was placed in a stock that paid 9% annual interest the total annual income from both investments, I, as a function of x is I= [ 0.14X+12350 ]
How can the total annual income from both investmentsbe expressed?The Amount that was invested =$13,000
Then the Profitable Investment which was givden as 9% can be expressed as = [ X(1.09) ]
Then from the question we can see the Negative Investment, which is -5% and can be expressed as = [ (13,000-X)(1-0.05) ]
The we can sum up as
I= [ X(1.09) ]+ [ (13000-X)(0.95) ]
This can be simplified as
I= [ 1.09X-0.95X+12350 ]
I= [ 0.14X+12350 ]

A marine biologist is studying the growth of a particular species of fish. She writes the following equation to show the length of the fish, f(m), in cm, after m months:
f(m) = 3(1.09)m
Part A: When the marine biologist concluded her study, the length of the fish was approximately 5.98 cm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(m) represent? (2 points)
Part C: What is the average rate of change of the function f(m) from m = 2 to m = 8, and what does it represent? (4 points)
The reasonable domain of the growth function is [0, 8], the y-intercept is 3 cm and the average rate of change of the function is 0.40 cm per month.
What is a growth function?The growth function, also called the shatter coefficient or the shattering number, measures the richness of a set family. It is especially used in the context of statistical learning theory, where it measures the complexity of a hypothesis class.
A marine biologist is studying the growth of a particular species of fish, given by the exponential equation,
f(m) = [tex]3(1.09)^{m}[/tex]
We need to find, reasonable domain to plot the growth function, the y-intercept of the graph of the function f(m) to represent and average rate of change of the function f(m) from m = 1 to m = 9,
f(m) = [tex]3(1.09)^{m}[/tex]
m = 0
f(0) = 3(1.09)⁰ = 3 cm
The length of the fish was approximately 5.98 cm.
5.98 = [tex]3(1.09)^{m}[/tex]
1.99 = [tex](1.09)^m[/tex]
m = 8
Domain = [0, 8]
Reasonable domain to plot the growth function = [0, 8]
The y-intercept of the graph of the function f(m) represent initial length of fish = 3 cm
The average rate of change of the function f(m) from m = 2 to m = 8
m = 2, f(2) = 3(1.09)² = 3.56 cm
m = 8, f(8) = 3(1.09)⁸ = 5.97 cm
Change in 8-2 = 6 months = 5.97-3.56 = 2.41 cm
The rate of change of the function f(m) from m = 2 to 8
= (2.41/6)
= 0.40 cm per month
Hence, the reasonable domain of the growth function is [0, 8], the y-intercept is 3 cm and the average rate of change of the function is 0.40 cm per month.

The table shows the number of each color pen in Mrs. Devon's desk drawer. Suppose she selects a pen at random from the drawer. How much greater is the theoretical probability of selecting a black pen than selecting a red or a green pen? Express your answer as a percent. Color Number of Pens Black 9 Blue 6 Green 1 Red 4
Answer:
Step-by-step explanation:
Black = 9, Blue = 6, Green = 1, Red = 4
Pr(Black) = 9/18 = 1/2 = 50%
Pr(Red or Green) = 5/18 = 28%
therefore it is 22% (50-28) more likely that Mrs. Devon will select a black pen than a red or green
Answer:
1. 9+6+1+4=20
Black 9/20 = 0.45 = 45%
Red or green = 5/20 = 0.25= 25%
selecting black is 45-25 = 20%

What is the liquid range of water?The liquid range of water refers to the temperature range at which water exists as a liquid. At standard atmospheric pressure (1 atm), the liquid range of water is from 0 degrees Celsius to 100 degrees Celsius, or from 32 degrees Fahrenheit to 212 degrees Fahrenheit.
This means that water can exist as a liquid within this temperature range, but if the temperature falls below 0 degrees Celsius or rises above 100 degrees Celsius, it will freeze into a solid or boil into a gas, respectively.
