Alice, Bob and Carol each think of an expression that is a fraction with 1 as the numerator and a constant integer times some power of x as the denominator. The simplest common denominator of Alice's and Bob's expressions is 4x2, while the simplest common denominator of Bob's and Carol's expressions is 12x3. The simplest common denominator of Alice's and Carol's expressions is 6x3. To explain further, Alice's expression can be any fraction with 1 as the numerator and a constant integer times x2 as the denominator, therefore, the denominator of Alice's expression can be any multiple of 4, i.e. 4x2, 8x2, 12x2, 16x2, 20x2 and so on.
Bob's expression can also be any fraction with 1 as the numerator and a constant integer times x2 as the denominator. However, the denominator of Bob's expression must be a multiple of both 4 and 6, i.e. 12x2, 24x2, 36x2, 48x2 and so on. Therefore, Carol's expression must be in the form of a fraction with 1 as the numerator and a constant integer times x3 as the denominator. This means that the denominator of Carol's expression must be a multiple of 6, i.e. 6x3, 12x3, 18x3, 24x3, 30x3 and so on. Hence, all possible expressions that could be Carol's are 1/6x3, 1/12x3, 1/18x3, 1/24x3, 1/30x3 and so on.

John borrows $2,500 from his dad, who feels it is best to charge him interest. Six months later, John repays his dad the loan plus interest, a total of $2,588. What is the annual interest rate on the loan?
well, we know that a year has 12 months, so 6 months is really just 6/12 of a year.
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$ 2588\\ P=\textit{original amount deposited}\dotfill & \$2500\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\to \frac{6}{12}\dotfill &\frac{1}{2} \end{cases}[/tex]
[tex]2588 = 2500[1+(\frac{r}{100})(\frac{1}{2})] \implies \cfrac{2588}{2500}=1+\cfrac{r}{200}\implies \cfrac{647}{625}=\cfrac{200+r}{200} \\\\\\ \cfrac{(200)(647)}{625}=200+r\implies \cfrac{(200)(647)}{625}-200=r\implies \boxed{7.04=r}[/tex]

Answer: Voluntary Response
Step-by-step explanation:
The question was, "Mrs. Finn had a terrible experience at a hotel last weekend. The water was cold, the bathroom wasn't cleaned, and it smelled really bad. She decided to write a horrible review on travel.com about the experience."
And we're asked to evaluate whether this is
A) Statistic
B) Random Sampling
C) Voluntary Response
A statistic is "any quantity computed from values in a sample which is considered for a statistical purpose."
Random sampling is "a method of data collection and analysis designed to select a representative sample of respondents out of a larger population."
Finally, we have voluntary response which is "a deliberately chosen reaction to a stimulus that may require a complex coordination of excitatory and inhibitory impulses with feedback from visual, motor, and other systems."
Out of all of the following definitions, voluntary response is what fits this scenario best. Voluntary response usually includes the response of people with very strong opinions, and recalling how Mrs. Finn reacted to her hotel, I'd say it fits.
"Zola sold 540 eggs. If these are 36% of the total eggs. Then how many are not sold?
Answer: 960 eggs are not sold.
Step-by-step explanation:
Let t be the number of total eggs.
36%(t) = 540
0.36(t) = 540
t = 1500
1500 - 540 = 960
Suppose 2 more students are times are added to the line plot. Each time added is 2 1/2 hours. Would the value that occurred the most often change?
Therefore, it is not possible to determine if the value that occurred the most often would change without knowing the frequency and values of the new data points.
Adding two more data points that are each 2 1/2 hours to a line plot would not necessarily change the value that occurred the most often. The value that occurred the most often would depend on the frequency of the new data points in relation to the existing data points. If the new data points have the same value as one of the existing data points, then the mode would not change. However, if the new data points have a different value than the existing data points, and they occur more frequently, then the mode would change.

Prove:
△BEC≅△DEA\triangle BEC \cong \triangle DEA
△BEC≅△DEA
We meet the SAS requirement for congruence because the two triangles share two congruent sides as well as the included angle.
To prove that △BEC≅△DEA, we can use the Side-Angle-Side (SAS) congruence theorem.
First, we can see that BE=ED, as both are radii of the same circle.
Secondly, angle BEC and angle DEA are both 90 degrees, as they are inscribed angles that subtend the same arc BD.
Lastly, we can see that EC=EA, as they are both radii of the same circle.
Therefore, we have the two triangles sharing two congruent sides and the included angle, satisfying the SAS criterion for congruence. Hence, we can conclude that △BEC≅△DEA.

Jorge has a flat tire and needs a new tire. Jorge is on a tight budget and needs to use the money he earns from his commission to pay for the new tire. The new tire costs $80. What minimum amount does Jorge need to sale for the week so that he can purchase a new tire? Jorge earns a 5% commission on his total sales
Jorge needs to sell at least $88.89 worth of products for the week in order to be able to purchase the new tire and cover his commission.
Describe a commission?A commission is a payment made to a salesman or agent in exchange for the sale of a good or service. Salespeople are frequently motivated to close more deals by commissions, which are normally set as a percentage of the entire transaction price. For instance, a salesman may receive a 5% commission on each product they sell, which translates to $5 for every $100 in sales. Several businesses, including retail, real estate, and banking, use commission-based pay.
Let us suppose the amount he needs to sell = x.
Thus, for 5% commission on his sales to purchase a $80 tire we have the equation:
x * 0.95 - 0.05x >= 80
0.9x >= 80
x >= 80/0.9
x >= 88.89
Therefore, Jorge needs to sell at least $88.89 worth of products for the week in order to be able to purchase the new tire and cover his commission.

The given data is shown below:X: 168 178 176 174 178 174 172Y: 50 57 55 55 58 54 53We know that y-intercept of the least squares line is given by b = ybar - m * xbarwhere xbar = (1/n) * ∑x and ybar = (1/n) * ∑y. Now, to calculate the slope of the least squares line, we need to calculate the value of the numerator of the following equation:Slope, m = [(n∑xy) - (∑x∑y)] / [(n∑x^2) - (∑x)^2]Here, ∑x and ∑y are the summations of x and y values, respectively. ∑xy is the sum of the products of each x and y value, and ∑x^2 is the sum of each x value squared. So, let's calculate all of these values for the given data.We have, n = 7∑x = 1202∑y = 382∑x^2 = 213468∑xy = 71848Now, substituting these values in the formula of slope, we have:Slope, m = [(7 * 71848) - (1202 * 382)] / [(7 * 213468) - (1202)^2] = 3.6000630680907Therefore, the slope of the least squares line is 3.600.

Find the linearization of the function √????(x,y)=18−2x2−3y2 at the point (1, -2).Use the linear approximation to estimate the value of ????(0.9,−1.9)f(0.9,−1.9) =
The linearization of the function √????(x,y)=18−2x2−3y2 at the point (1, -2) is (x,y)≈6.4−4(x−1)−6(y+2). Using this linear approximation, we can estimate the value of (0.9,−1.9) to be approximately 6.1.
To explain further, linear approximation is a method used to approximate a function with a linear equation near a given point. We use linear approximation to estimate the value of a function at a certain point without actually having to evaluate it.
First, we find the linearization of the function √????(x,y)=18−2x2−3y2 at the point (1, -2). We do this by finding the derivative of ????(x,y) with respect to x and y and substituting the coordinates of the given point.
Taking the partial derivative of ????(x,y) with respect to x, we get ????x(x,y)=4x−4 and substituting x = 1 and y = -2, we get ????x(1,−2)=−4.
Similarly, taking the partial derivative of ????(x,y) with respect to y, we get ????y(x,y)=−6y−6 and substituting x = 1 and y = -2, we get ????y(1,−2)=18.
Therefore, the linearization of the function √????(x,y)=18−2x2−3y2 at the point (1, -2) is ????(x,y)≈6.4−4(x−1)−6(y+2).
Using this linear approximation, we can estimate the value of ????(0.9,−1.9) to be approximately 6.1. We do this by substituting x = 0.9 and y = -1.9 in the linear approximation, which gives us ????(0.9,−1.9)≈6.1.
Hence, the value of ????(0.9,−1.9) is estimated to be approximately 6.1 using the linear approximation of the function ????(x,y)=18−2x2−3y2 at the point (1, -2).

words from a written text the person can remember after five minutes with the text.
The words from a written text that a person can remember after five minutes with the text are known as short-term memory.
Short-term memory refers to the storage of information for a brief period of time, usually a few seconds to a few minutes. It is a type of memory that is involved in the conscious processing of information and is responsible for holding information in mind for immediate use.
The capacity of short-term memory is limited and varies from person to person. Generally, it can hold about 7 pieces of information or less, and can only hold it for a short period of time. This is why it is important to transfer important information from short-term memory to long-term memory through a process called encoding.
To improve short-term memory, one can use techniques such as repetition, chunking, visualization, and association. By doing this, it is possible to hold more information in short-term memory for a longer period of time.

Example 22: Find angle a, b and c ? a bº Co 106⁰ 35
According to the figure the value of a b and c is
a = 39
b = 141
c = 39
How to find the anglesThe angles are solved using the concept of sum of angles in a triangle is equal to 180 degrees
Solving for a
a + 106 + 35 = 180
a + 106 + 35 = 180
a + 141 = 180
Next, we can isolate a by subtracting 141 from both sides:

1 / P = (-4 + 5 / t) / N
Next, we can cross-multiply:
N / P = -4 + 5 / t
And then isolate t:
N / P + 4 = 5 / t
t = 5 / (N / P + 4)
Therefore, t = 5 / (N/P + 4) is the solution for t.

x (Please put your answer as a decimal. )
The solution to the equation is x = 22.5.
To solve the equation x-9 = (3/5)x, we can first simplify the right-hand side by multiplying both sides by 5 to get rid of the fraction:
5(x-9) = 3x
An equation is a mathematical statement that indicates the equality of two expressions. Equations typically contain variables, which are represented by letters, and mathematical operations such as addition, subtraction, multiplication, and division. The expressions on either side of the equals sign are called the left-hand side and right-hand side of the equation.
Expanding the left-hand side, we get
5x - 45 = 3x
Next, we can simplify by subtracting 3x from both sides:
2x - 45 = 0
Adding 45 to both sides, we get:
2x = 45
Finally, dividing both sides by 2, we get:
x = 22.5

Step-by-step explanation:
A\:pair\:of\:parallel\:power\:lines\:are\:installed\:on\:a\:slope\:find\:m<\:3\:if\:m<\:2=143
According to the slope, the angle 3 also has a measure of 143 degrees.
To find the measure of angle 3, we first need to understand how angles 2 and 3 are related.
In other words, angles 2 and 3 are congruent (have the same measure). Therefore, if we can find the measure of angle 2, we can determine the measure of angle 3.
We know that angle 2 has a measure of 143 degrees. We also know that angles 2 and 3 are alternate interior angles, which means they are congruent.
Now, let's justify why this is true using the concept of slopes. Since the power lines are parallel, they have the same slope. This means that the angle between each power line and the horizontal is the same.
Since angle 2 is the angle between one of the power lines and the horizontal, we know that angle 3 must also have the same measure because it is the angle between the other power line and the horizontal.
Therefore, we can confidently say that the measure of angle 3 is also 143 degrees.

Form an equation in u and show it simplifies to 2u^2-20u+36=0
(u - 5 + (7))(u - 5 - (7)) = 0 is the equation we created in u that simplifies to 2u2 - 20u + 36 = 0.
What exactly are equations, and what varieties exist?The two forms of equations are identity equations and conditional equations. The variables all have the same identity for all conceivable values.
Creating an equation in u that can be solved for 2u² - 20u + 36 = 0
It indicates that the following are the solutions for x for a quadratic equation of the form ax² + bx + c = 0:
x = (-b±√(b²-4ac))/2a
By dividing both sides by 2, we can rewrite the equation 2u2 - 20u + 36 = 0 as follows:
u² - 10u + 18 = 0
u = (-(-10) ± √((-10)² - 4(1)(18))) / 2(1)
Simplifying this expression, we get:
u = (10 ± √(100 - 72)) / 2
u = (10 ± √(28)) / 2
u = (10 ± 2√(7)) / 2
u = 5 ± √(7)
A quadratic equation with roots r1 and r2 can be expressed as: This allows us to merge the two solutions into a single equation.
(x - r1)(x - r2) = 0
By substituting in the two answers we discovered for u, we obtain:
(u - 5 + √(7))(u - 5 - √(7)) = 0
Extending this phrase results in:
u² - 10u + 18 = 0
