The constant of proportionality, which is the cost per pair of jeans, is found by dividing the total cost by the number of pairs. For Alyssa's purchase of 3 pairs of jeans for $92.31, the constant of proportionality is $30.77 per pair.
Explanation:To determine the constant of proportionality for the jeans Alyssa bought, we need to divide the total cost by the number of pairs of jeans she purchased. Since Alyssa bought 3 pairs of jeans for $92.31, we calculate the constant of proportionality as follows:
Therefore, the constant of proportionality is $30.77 per pair of jeans.
Final answer:
The constant of proportionality, or the cost per pair of blue jeans, is $30.77 calculated by dividing the total cost of $92.31 by the number of blue jeans, which is 3.
Explanation:
The student has asked how to find the constant of proportionality, which in this context is the cost per pair of blue jeans when buying multiple pairs. If Alyssa bought 3 pairs of blue jeans for a total of $92.31 on tax free weekend, we can calculate the cost per pair by dividing the total cost by the number of pairs. The constant of proportionality would be: $92.31 / 3 = $30.77 per pair of jeans.

A linear transformation of the form z = Γx was applied to the data, where Γ is a 2 × 2 matrix. The decision boundary associated with the BDR is now the hyperplane of normal w = (1/ √ 2, −1/ √ 2)T which passes through the origin.
Answer:
Part a: The transformation matrix is the clockwise rotation matrix of π/4.
Part b: The hyperplane would move towards the mean of class 1.
Part c: The distance will remain in the Euclidean Space due to the rotation transformation only.
Step-by-step explanation:
As the complete question is not available, the question is searched online and a reference question is obtained which has 3 parts as follows:
Part a:
The decision boundary after transformation coincides with the line x1 = x2, the two class means must lie on a line that is normal to the decision boundary, i.e. on x1 = −x2. This implies that the transformation matrix Γ is a clockwise rotation transformation of π/4, given as
[tex]\Gamma=\left[\begin{array}{cc}\frac{\sqrt{2}}{2}&\frac{\sqrt{2}}{2}\\\frac{-\sqrt{2}}{2}&\frac{\sqrt{2}}{2}\end{array}\right][/tex]
Part b:
If the prior probability of class 0 was increased after transformation, then the decision boundary of BDR would still have the same normal as before, i.e.,[tex]w=(1/\sqrt{2},-/\sqrt{2})^T[/tex], but move toward the mean of class 1.
Part c:
Noting that
[tex]||\bold{T}_x-\bold{T}_y||^2=(x-y)^T \bold{T}^T\bold{T}(x-y)\\||\bold{T}_x-\bold{T}_y||^2=(x-y)^T(x-y)\\||\bold{T}_x-\bold{T}_y||^2=||x-y||^2[/tex]
This indicates that the distance is still the same and is in Euclidean space. This is due to the fact that rotation transformations does not affect the distances between the points.
Zak has a bag of cherries. He gave away 18 cherries to tim and 18 cherries to janet. Now he has 25 cherries. H ow many cherries did zack have at the start?
Answer: he had 68 cherries in the start
Step-by-step explanation:
In the beginning, Zak had 61 cherries and he gave away 18 cherries to Tim and 18 cherries to Janet.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Cherries are in a bag that Zak possesses. Tim and Janet each received 18 cherries from him. He currently has 25 cherries.
Let's assume the number of cherries Zak had at the start "x".
Zak gave away 18 cherries to Tim and 18 cherries to Janet, so he now has x - 18 - 18 = 25 cherries.
You can solve this equation for x by adding 18 + 18 to both sides, which gives you x = 25 + 18 + 18.
This simplifies to x = 61, so Zak had 61 cherries at the start.

The publisher will sell Carlita's book to bookstores for $26.40 per copy. The retail price for customers to pay will be $48. Carlita expects to sell 225,000 copies. The publisher's expenses will be: • Printing: $3.75 per copy • Editing/Design: $27,500 • Publicity/Advertising/ Administrative: $135,150 • Carlita's Author Fee: 6.5% of the suggested retail price of every book sold Carlita suddenly announces that she wants to insert a kelp bookmark in each copy. The publisher thinks this will guarantee sales, but Carlita must agree to pay for 1/3 of the cost of the kelp. If the publisher expects the total profit on the book with the added expense to be $4,092,100, how much should Carlita expect to pay for her share of the kelp? just so i dont scroll up
Answer:
$151,800
Step-by-step explanation:
For the publisher, the expected revenue is $26.40 per copy. For 225,000 copies, the revenue is [tex]225000\times26.40 = 5,940,000[/tex]
The expenses incurred by the publisher are as follows:
Cost of 1 print = $3.75
Cost of 225,000 prints = [tex]225000\times3.75 = 843,750[/tex]
Editing/Design = $27,500
Publicity/Advertising/Administrative = $135,150
Author's fee = 6.5% of retail price per copy for 225,000 copies = [tex]225000\times26.40\times6.5/100= 386,100[/tex]
Total cost = 843,750 + 27,500 + 135,150 + 386,100 = $1,392,500
Let the cost of kelp for copies be k.
Then the total cost = 1,392,500 + k
If the expected profit is 4,092,100, then
Revenue = total cost + profit
5,940,000 = 1,392,500 + k + 4,092,100
5,940,000 = 5,484,600 + k
k = 5,940,000 - 5,484,600 = 455,400
Since Carlita is paying [tex]\frac{1}{3}[/tex] of k, her share of the kelp =
[tex]\frac{1}{3}\times455400 = 151800[/tex]
Carlita will pay $151,800
Randy's circular garden has a radius of 1.5 feet.He wants to enclose the garden with edging that costs $0.75 per foot. About how much will the edging cost
Answer:Circumference = 2 \pi r
circumference = 2 \pi (1.5)
circumference = 9.42 feet
The circumference is 9.42 feet, so we need to get fencing for 10 feet (assuming the fence comes in feet, i.e. you cant buy half a foot)
1 feet = $.075
10 feet = $0.75 x 10 = $7.50
In the image below, DE || BC. Find the measure of EC. Set up a proportion and solve for the measure. Show your work and label your answer. Please help me -- I will mark brainliest; If your response is inapropriate, or just a way to get points, it will get reported! Thank you so much !
The missing figure is attached down
Answer:
The measure of EC is 1 foot
Step-by-step explanation:
Let us revise the cases of similarity
AAA similarity : two triangles are similar if all three angles in the first triangle equal the corresponding angle in the second triangleAA similarity : If two angles of one triangle are equal to the corresponding angles of the other triangle, then the two triangles are similar.SSS similarity : If the corresponding sides of the two triangles are proportional, then the two triangles are similar.SAS similarity : In two triangles, if two sets of corresponding sides are proportional and the included angles are equal then the two triangles are similar.From the attached figure
∵ DE // BC
∴ ∠ADE ≅ ABC ⇒ corresponding angles
∴ ∠AED ≅ ACB ⇒ corresponding angles
In Δs ADE and ABC
∵ ∠ADE ≅ ABC ⇒ proved
∵ ∠AED ≅ ACB ⇒ proved
∵ ∠A is a common angle in the two triangles
∴ Δ ADE is similar to triangle ABC by AAA postulate
From the results of similarity the corresponding sides of the triangles are proportion
∴ [tex]\frac{AD}{AB}=\frac{DE}{BC}=\frac{AE}{AC}[/tex]
∵ AD = 8 feet
∵ DB = 2 feet
∴ AB = AD + DB
∴ AB = 8 + 2 = 10 feet
∵ AE = 4 feet
By using the proportion statement above [tex]\frac{AD}{AB}=\frac{AE}{AC}[/tex]
∴ [tex]\frac{8}{10}=\frac{4}{AC}[/tex]
By using cross multiplication
∴ 8 × AC = 10 × 4
∴ 8 AC = 40
Divide both sides by 8
∴ AC = 5 feet
∵ AC = AE + EC
∴ 5 = 4 + EC
Subtract 4 from both sides
∴ 1 = EC
∴ The measure of EC is 1 foot
A hat contains four red marbles, two blue marbles, seven green marbles, and one orange marble. If two marbles are picked out of the hat randomly, what is the probability that one will be orange and one will be blue?
A. 98 percent
B. 1/98
C. 3/14
D. 1/7
E. 3 percent
Answer: B. [tex]\dfrac{1}{98}[/tex].
Step-by-step explanation:
Given : A hat contains four red marbles, two blue marbles, seven green marbles, and one orange marble.
Total marbles = 4+2+7+1 = 14
P(Blue)= [tex]\dfrac{2}{14}=\dfrac{1}{7}[/tex]
P(Orange) = [tex]\dfrac{1}{14}[/tex]
if we randomly select two marbles , then the probability of selecting one will be orange and one will be blue marble = P(Blue) x P(Orange) [both events are independent]
[tex]=\dfrac{1}{7}\times\dfrac{1}{14}=\dfrac{1}{98}[/tex]
Hence, the probability that one will be orange and one will be blue is [tex]\dfrac{1}{98}[/tex].
Therefore , the correct answer is B. [tex]\dfrac{1}{98}[/tex].

Write an explicit formula for the arithmetic sequence 15.6, 15, 14.4, 13.8,..., and then find the 32nd term.
Answer: the 32nd term is - 3
Step-by-step explanation:
The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + d(n - 1)
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 15.6
d = 15 - 15.6 = 14.4 - 15 = - 0.6
n = 32
The explicit formula for the arithmetic sequence is
Tn = 15.6 - 0.6(n - 1)
We want to determine the value of the 32nd term, T32. Therefore,
T32= 15.6 - 0.6 (32 - 1)
T32 = 15.6 - 18.6
T32 = - 3

The probability that the student knows the answer given that he answered it correctly is [tex]\dfrac{12}{13}[/tex] .
Jenna is helping her mom plant new flowers for the spring she has 45 red tulips and 63 yellow tulips if she puts the same number of tulips in each row and only one color per row what is the greatest number of tulips each row can have
Answer:
9
Step-by-step explanation:
Number of tulips per row has to be a factor of the number of available tulips.
Red tulips: 45 = 3×3×5
Yellow tulips: 63 = 3×3×7
Highest no. of tulips each row is 9 (3×3 = 9)
What is the area of this triangle.
Answer:
13 square units
Step-by-step explanation:
You could calculate the length of each side using Pythagorean theorem, then use Heron's formula to find the area. But there's an easier way: find the area of the rectangle that contains the triangle, and subtract the areas of the smaller triangles in the corners.
The area of the rectangle is 4 × 7 = 28.
The area of the upper left triangle is ½(2)(4) = 4.
The area of the upper right triangle is ½(3)(5) = 7.5.
The area of the lower right triangle is ½(1)(7) = 3.5.
So the area of the triangle is:
28 − 4 − 7.5 − 3.5 = 13
Sarah says that you can find the LCM of any two whole numbers by multiplying them together. Provide a counter example to show that Sarah's statement is incorrect
Answer:
4·6 = 24 ≠ 12 = LCM(4, 6)
Step-by-step explanation:
Any pair of numbers with a common factor will refute Sarah's conjecture.
One such pair is 4 and 6, which have a product of 24. The LCM of 4 and 6 is 12, which is that product divided by their common factor of 2.
Sarah's statement is incorrect.
Sarah's statement that the least common multiple (LCM) of any two whole numbers is obtained by merely multiplying them together is incorrect. For example, consider the whole numbers 8 and 12. The product of these two numbers is 8 * 12 = 96. However, the LCM of 8 and 12 is actually 24, since 24 is the smallest number that is divisible by both 8 and 12. To find the LCM of two numbers, you need to list their multiples and find the smallest number that appears on both lists (in this case, the multiples of 8 are 8, 16, 24, 32, ... and the multiples of 12 are 12, 24, 36, 48, ...).
Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the high temperature of 90 degrees occurs at 4 PM and the average temperature for the day is 70 degrees. Find the temperature, to the nearest degree, at 9 AM
Answer:
65°
Step-by-step explanation:
Since the high is given, it is convenient to use that value with a cosine function to model the temperature. The function will be ...
T = A + Bcos(C(x-D))
where A is the average temperature, B is the difference between the high and the average, C is π/12, reflecting the 24-hour period, and D is the time at which the temperature is a maximum. "x" is hours after midnight.
We have chosen to use a 24-hour clock with x=16 at 4 pm. Then the value of T at 9 am is ...
T = 70 +20cos((π/12(9 - 16)) = 70 +20cos(7π/12) ≈ 64.824
The temperature at 9 am is about 65°.
Final answer:
To find the temperature at 9 AM, a sinusoidal function is constructed with an amplitude of 20 degrees, a vertical shift of 70 degrees, and a phase shift adjusted for a high at 4 PM. Plugging in the time value of 9 AM into the function, it is determined that the temperature at 9 AM is approximately the same as the average or midline temperature, which is 70 degrees.
Explanation:
To find the temperature at 9 AM using a sinusoidal function, we first identify essential characteristics of the function. The maximum temperature (high) of 90 degrees occurs at 4 PM (which we'll take as 16 hours on a 24-hour clock) and the average temperature for the day is 70 degrees, which is also the midline of the sinusoidal function. Since this is a typical daily temperature cycle, we assume that the minimum temperature occurs 12 hours after the maximum temperature. Thus, the temperature will have a periodicity of 24 hours. The amplitude of the temperature variation will be the difference between the high temperature and the average temperature (which is 20 degrees in this case).
The sinusoidal function can be written in the form:
T(t) = A · sin(B(t - C)) + D
Where:
C is the phase shift (16 hours for 4 PM)
Using this information, the sinusoidal function for temperature throughout the day is:
T(t) = 20 · sin((2π/24)(t - 16)) + 70
We then plug in t = 9 (for 9 AM), and calculate the temperature:
T(9) ≈ 20 · sin((2π/24)(9 - 16)) + 70
Which gives us, to the nearest degree:
Temperature at 9 AM ≈ 70 degrees.
Since the value of the sine function ranges from -1 to 1, at 9 AM (7 hours before the maximum temperature at 4 PM), the sine value would be negative indicating that the temperature is rising from the minimum towards the average. However, due to the characteristics of sine, the temperature at 9 AM will actually be the same as the temperature at 19 hours (7 PM), which is also 70 degrees.

Claire traveled 701 miles. She drove 80 miles every day. On the last day of her trip she only drove 61 miles. Write and solve an equation to find the number of days Claire traveled. Explain each step of your problem solving strategy.
Answer:
Claire traveled for 9 days.
Step-by-step explanation:
Given:
Total Distance traveled = 701 miles
Distance traveled each day = 80 miles
Distance traveled on last day = 61 miles
We need to find the number of days Claire traveled.
Solution:
Let the number of days Claire traveled be denoted by 'd'.
Now we can say that;
Total Distance traveled is equal to sum of Distance traveled each day multiplied by number of days and Distance traveled on last day.
framing in equation form we get;
[tex]80d+61=701[/tex]
Now Subtracting both side by 61 using Subtraction Property of Equality we get;
[tex]80d+61-61=701-61\\\\80d = 640[/tex]
Now Dividing both side by 80 we get;
[tex]\frac{80d}{80}=\frac{640}{80}\\\\d=8[/tex]
Hence Claire traveled 80 miles in 8 days and 61 miles on last day making of total 9 days of travel.

At a certain university, 42% of the students are women and 18% of the students are engineering majors. Of the engineers, 22% are women. If a student at this university is selected at random, what is the probability that the selected person is a woman engineering major?
Answer:
The probability that the selected person is a woman engineering major is 0.0396.
Step-by-step explanation:
The proportion of students at the university who are women is 0.42.
P (W) = 0.42
The proportion of students at the university who are engineering majors is 0.18.
P (E) = 0.18
The proportion of engineering majors that are women is 0.22.
P (W|E) = 0.22
The proportion of students at the university that are woman and engineering major is:
[tex]P (W|E)=\frac{P(W\cap E)}{P(E)} \\P(W\cap E)=P(W|E)\times P(E)\\= 0.18\times0.22\\=0.0396[/tex]
Thus, the probability that the selected person is a woman engineering major is 0.0396.
The probability that a randomly selected student from the university is a woman engineering major is 99/100.
To find this probability, we will use the information given about the percentages of women and engineering majors at the university, as well as the percentage of women among the engineering majors.
First, let's denote the total number of students at the university as T.
According to the information given:
- 42% of the students are women, so the number of women students is 0.42T
- 18% of the students are engineering majors, so the number of engineering students is 0.18T
- Of the engineers, 22% are women, so the number of women engineering students is 0.22 \times 0.18T.
Now, we want to find the probability that a randomly selected student is a woman engineering major. Probability is defined as the number of favorable outcomes divided by the total number of possible outcomes. In this case, the favorable outcomes are the number of women engineering majors, and the total number of possible outcomes is the total number of students.
The probability P that a randomly selected student is a woman engineering major is:
[tex]\[ P = \frac{\text{Number of women engineering majors}}{\text{Total number of students}} \][/tex]
[tex]\[ P = \frac{0.22 \times 0.18T}{T} \][/tex]
Since [tex]$T$[/tex]is in both the numerator and the denominator, it cancels out, leaving us with:
[tex]\[ P = 0.22 \times 0.18 \][/tex]
[tex]\[ P = 0.0396 \][/tex]
To express this probability as a fraction, we can write it as:
[tex]\[ P = \frac{396}{10000} \][/tex]
Simplifying this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4, we get:
[tex]\[ P = \frac{99}{2500} \][/tex]
A loan of P500,000 was signed by Liza who promised to pay it at the beginning of each month for 5 years. If money is worth 12% compounded monthly, what will be the total sum paid by Liza?
Answer:
3,604,389
Step-by-step explanation:
Monthly payment P = [tex]\frac{a}{[(1+r)^{n} - 1] / [r(1+r)^{n}] }[/tex]
where a = total loan amount, r = periodic rate, n = number of payment periods
a = 500,000 ; r = 0.12 ; n = (5 x 12) = 60 months
P = [tex]\frac{500000}{[(1+0.12)^{60} - 1] / [0.12 (1+0.12)^{60} ] }[/tex]
P = [tex]\frac{500000}{(896.597) / (107.712)}[/tex]
p = 60,073.151
Total amount paid = 60073.151 x 60 = 3,604,389
Final answer:
Liza will have to pay a monthly amount of P2,997.75 for a loan of P500,000 at a 12% interest rate compounded monthly over 5 years. The total amount paid at the end of the term will be P179,865.
Explanation:
To determine the total sum Liza will pay for a loan of P500,000 with an interest rate of 12% compounded monthly over 5 years, we first need to calculate the monthly payment she would need to make. The problem is essentially asking to find the annuity payment for a present value, which can be calculated using the formula for present value of an ordinary annuity:
PV = PMT * [1 - (1 + r)-n] / r
Where:
PV = Present Value of the annuity (P500,000 in this case)
PMT = Monthly payment
r = Monthly interest rate (12% per year compounded monthly, so 0.12/12 per month)
n = Total number of payments (5 years × 12 months/year = 60 payments)
First, we calculate the monthly interest rate:
r = 0.12 / 12 = 0.01 or 1%
Now, setting up the equation:
500,000 = PMT * [1 - (1 + 0.01)-60] / 0.01
We find that PMT = 500,000 / 166.7916 (Using the present value factor derived from the reference information)
PMT = P2997.752
Therefore, the monthly payment Liza has to make is P2,997.75. To find the total sum paid after 5 years:
Total Sum = Monthly Payment * Number of Payments
Total Sum = P2,997.75 * 60 = P179,865

Find CU. If necessary, round answers to 4 decimal places Show all your work for full credit. Hint: Use the Pythagorean Theorem first.
Answer:
3
Step-by-step explanation:
You'll need to use the Angle Bisector Theorem.
CU / ZU = BC / BZ
From the first part of the problem, you used Pythagorean theorem to find that BZ = 10.
Let's say that CU = x. That means ZU = 8 − x. Plugging in values:
x / (8 − x) = 6 / 10
Cross multiply:
10x = 6(8 − x)
Solve:
10x = 48 − 6x
16x = 48
x = 3
On Friday, the With-It Clothiers sold some jeans at $25 a pair and some shirts at $18 each. receipts for the day totaled $441. On Saturday the store priced both items at $20, sold exactly the same number of each item, and had receipts of $420. How many pairs of jeans and how many shirts were sold each day?
9 pairs of jeans and 12 shirts were sold on each day.
Explanation:Let x be the number of jeans sold and y be the number of shirts sold. From the given information, we can form two equations:
25x + 18y = 441 (equation 1)
20x + 20y = 420 (equation 2)
Multiplying equation 2 by 5, we get 100x + 100y = 2100. Subtracting this equation from equation 1, we get -75x - 82y = -1659. Solving this equation, we find that x = 9 and y = 12.
Therefore, 9 pairs of jeans and 12 shirts were sold on each day.

Polynomial and rational functions can be used to model a wide variety of phenomena of science, technology, and everyday life. Choose one of these sectors and give an example of a polynomial or rational function modeling a situation in that sector.
Answer:
L = s^2/(30.25Cd)
Step-by-step explanation:
In accident investigation, the speed of a vehicle can be estimated using a polynomial function that relates speed (s) to the length of skid marks (L). The drag coefficient Cd will depend on the condition of the road surface and tires, but might be expected to be between 0.7 and 0.8.
If the skid marks end in a collision, the length of the marks that might have been made can be estimated using this formula, then that length added to the actual length of marks to estimate the original speed. The speed at the point of collision can be estimated by the damage caused, and/or the movement created.
In the above formula, length is in feet, and speed is in miles per hour.
In Physics, a polynomial function such as[tex]y = -gt^2 + v0*t + h0[/tex] can model an object's motion under gravity. A rational function like P = a / (1 + bQ) can model the relationship between supply and demand in Economics.
Explanation:In the field of Physics, polynomial functions are often used to model physical phenomena. For example, the motion of an object under the force of gravity can be represented by a second-degree polynomial, or quadratic function. The equation[tex]y = -gt^2 + v0*t + h0[/tex]is an example of a quadratic function modeling free fall, where g represents the acceleration due to gravity, v0 is initial velocity, t represents time and h0 is initial height.
On the other hand, rational functions are used in various fields too. In Economics for instance, it can model situations like the relationship between supply and demand in market equilibrium. A simple model could be P = a / (1 + bQ) where P represents the price, Q is the quantity of good sold, and a, b are constants.
