The original price of the product was approximately $98.00.
How to determine the original price of a product after a given markdown?To determine the original price before the 15.5% decrease, we can use the following equation:
Original price - (15.5% of original price) = $82.81
Let's solve for the original price:
Original price - (0.155 * Original price) = $82.81
Simplifying the equation:
0.845 * Original price = $82.81
Dividing both sides by 0.845:
Original price = $82.81 / 0.845
Calculating the original price:
Original price ≈ $98.00
Therefore, the original price of the product was approximately $98.00.

Solve the seperable differential equation 1 9yy' = 2. Use the following initial condition: y(9) = 7. = Express x? in terms of y. x2 = (function of y).
the solution to the differential equation is: x = (1/36) y² - (13/36) Note that this equation represents a parabolic curve in the (x,y)-plane, opening upwards and with its vertex at (-13/36,0).
We can start by separating the variables and integrating both sides of the equation:
1/9 y dy = 2 dx
Integrating both sides with respect to their respective variables, we get:
(1/18) y² = 2x + C
where C is the constant of integration.
Using the initial condition y(9) = 7, we can substitute x=9 and y=7 to solve for C:
(1/18) (7²) = 2(9) + C
C = 49/2 - 18 = 13/2
Substituting this value of C back into the general solution, we get:
(1/18) y² = 2x + 13/2
Simplifying and solving for x, we get:
x = (1/36) y² - (13/36)
Therefore, the solution to the differential equation is:
x = (1/36) y² - (13/36)

Cooper is studying two fractions that are both less than 1 the first fraction has a denominator of 4 and rounds to 1. the second fraction has a denominator of 6 and the same numerator as the first fraction is the second fraction closest to 1 or 17 explain
The first fraction is closer to 1, while the second fraction is closer to 17.
Let's first determine the value of the first fraction with a denominator of 4, which rounds to 1.
Since the fraction is less than 1 and rounds to 1, its numerator must be 3. Therefore, the first fraction is:
3/4 = 0.75
Now let's consider the second fraction, which has a denominator of 6 and the same numerator as the first fraction. So its value is:
3/6 = 1/2 = 0.5
To determine which fraction is closer to 1 or 17, we need to calculate the absolute difference between the value of each fraction and 1 or 17, and then compare those differences.
For the first fraction, the absolute difference between 0.75 and 1 is:
|1 - 0.75| = 0.25
The absolute difference between 0.75 and 17 is:
|17 - 0.75| = 16.25
For the second fraction, the absolute difference between 0.5 and 1 is:
|1 - 0.5| = 0.5
The absolute difference between 0.5 and 17 is:
|17 - 0.5| = 16.5

The standard deviation of the scores on a skill evaluation test is 320 points with a mean of 1434 points. if 338 tests are sampled, what is the probability that the mean of the sample would differ from the population mean by less than 43 points? round your answer to four decimal places.
The probability that the mean of the sample would differ from the population mean by less than 43 points is approximately 0.7597 or 0.7600 (rounded to four decimal places).
Given that the standard deviation of the scores on a skill evaluation test is 320 points with a mean of 1434 points. And we have a sample of size n = 338.
We need to find the probability that the mean of the sample would differ from the population mean by less than 43 points.
The standard error of the mean is given by:
SE = σ/√n
where σ is the population standard deviation and n is the sample size.
Substituting the given values, we get:
SE = 320/√338
SE ≈ 17.398
To find the probability, we need to standardize the sample mean using the standard error as follows:
Z = (X - μ) / SE
where X is the sample mean, μ is the population mean, and SE is the standard error of the mean.
Substituting the given values, we get:
Z = (1434 - 1434) / 17.398
Z = 0
Since the mean difference is 0, we can find the probability of a difference less than 43 points by finding the probability that Z lies between -43/17.398 and 43/17.398.
Using a standard normal distribution table or calculator, we find that this probability is approximately 0.7597.
Therefore, the probability that the mean of the sample would differ from the population mean by less than 43 points is approximately 0.7597 or 0.7600 (rounded to four decimal places).

An object has a mass of 4. 70g. Calculate the Density of the object volume is 2. 55L
The density of the object is 0.0018 g/mL.
To calculate the density of the object, we need to use the formula:
Density = Mass / Volume
Given that the mass of the object is 4.70g and the volume is 2.55L, we can substitute these values into the formula:
Density = 4.70g / 2.55L
We need to convert the units of mass and volume to a consistent unit. Let's convert the volume from liters to milliliters (1L = 1000mL):
Density = 4.70g / 2550mL
Now we can simplify by dividing both the numerator and denominator by 10:
Density = 0.47g / 255mL

What is the difference in credit score between those over the age of 55 and those between 18-24 years old?
According to recent studies, there is a notable difference in credit scores between those over the age of 55 and those between the ages of 18-24.
On average, individuals over the age of 55 tend to have higher credit scores than those in the 18-24 age range. This is primarily due to the fact that older individuals have had more time to establish and build their credit history, whereas younger individuals are just starting out and may not have had the opportunity to establish credit yet.
Additionally, older individuals tend to have more stable financial situations and may have less debt compared to younger individuals who may be dealing with student loans or other types of debt.
However, it's important to note that credit scores can vary greatly between individuals, regardless of age, and there are many factors that contribute to credit score, such as payment history, credit utilization, and length of credit history.

The y axis is labeled Number of Strawberries and the x axis is labeled Days in February Part A: Using computer software, a correlation coefficient of r = 0. 01 was calculated. Based on the scatter plot, is that an accurate value for this data? Why or why not? Part B: Instead of comparing the number of strawberries picked and the day in February, write a scenario that would be a causal relationship for strawberries picked on the farm
Weak correlation observed in scatter plot, inaccurate r=0.01 value; possible causal relationship - new fertilizer's effect on strawberry yields.
Part A: How accurate is the correlation coefficient?Based on the scatter plot, a correlation coefficient of r=0.01 is not an accurate value for this data. This is because the scatter plot shows an upward trend with moderately spread out points from the line of best fit, indicating a weak positive correlation. A correlation coefficient of 0.01 suggests a near-zero correlation, which is inconsistent with the observed pattern in the scatter plot.
Part B: How can a causal relationship be established?A possible scenario for a causal relationship for strawberries picked on the farm could be the application of a new fertilizer that is known to increase strawberry yields. The farmer could divide the field in half, applying the new fertilizer to one half and the traditional fertilizer to the other half, and then compare the yields of each half. This would allow for a comparison of the effect of the two different fertilizers on strawberry yields and establish a causal relationship between the fertilizer and the yield of strawberries.

the following list shows the number of goals scored by a soccer team in each of 9 games. 0 0 1 1 1 3 3 4 5 how does the median number of goals scored compare with the mean number of goals scored? responses
The median number of goals scored is 1, and the mean number of goals scored is 2. The median is less than the mean, indicating a right-skewed distribution.
To find the median, we need to first put the numbers in order
0, 0, 1, 1, 1, 3, 3, 4, 5
There are an odd number of values, so the median is the middle value, which is 1.
To find the mean, we add up all the values and divide by the number of values
(0 + 0 + 1 + 1 + 1 + 3 + 3 + 4 + 5) / 9 = 2
So the mean number of goals scored is 2.
Since the median (1) is less than the mean (2), we can say that the distribution is skewed to the right. This is because the high value of 5 pulls the mean up, while the median is not affected as much by outliers.

Larray bought roses at the flower shop for $4.50 per dozen with a 90% markup. what is the final retail price
A markup refers to the amount that is added on top of the cost price of a product to arrive at the selling price. In this case, the cost price of the roses was $4.50 per dozen. Therefore, a 90% markup would mean that the selling price is 90% more than the cost price.
To calculate the markup, we can use the following formula:
Markup = Cost Price x Markup Percentage
Markup Percentage = 90% = 0.9 (in decimal form)
Markup = $4.50 x 0.9 = $4.05
This means that the markup on the roses is $4.05 per dozen.
To calculate the final retail price, we simply need to add the markup to the cost price:
Retail Price = Cost Price + Markup
Retail Price = $4.50 + $4.05 = $8.55
Therefore, the final retail price for the roses that Larray bought at the flower shop is $8.55 per dozen.
In conclusion, Larray bought roses at the flower shop for $4.50 per dozen with a 90% markup, which resulted in a final retail price of $8.55 per dozen. The markup was calculated by multiplying the cost price by the markup percentage of 90%, and then adding it to the cost price to arrive at the selling price.
This is a common practice in the flower industry, where flower shops add a markup to the cost of their products to make a profit.

1. at which location in new york state
would one least expect to find fossils in
the surface bedrock?
One would least expect to find fossils in the surface bedrock in the Adirondack Mountains region of New York State.
This region is known for having some of the oldest rocks in North America, dating back over a billion years. These rocks were formed through volcanic activity and mountain-building processes that occurred long before the evolution of complex life forms.
As a result, the rocks in the Adirondack Mountains are generally not rich in fossils, especially those of plants and animals that evolved much later in Earth's history.
In contrast, other regions of New York State, such as the Hudson Valley and the Finger Lakes region, have rocks that are more conducive to fossil preservation. These regions were covered by shallow seas at various times in the past, allowing for the accumulation of sediment and the preservation of fossils of marine organisms.

Find the absolute extrema if they exist, as well as all values of where they occur, for the function f(x) = 8+x/2-x on the domain [-2, 0]
Find the derivative of f(x) = 8+x/2-x
f'(x) = ...
The absolute maximum is f(-2) = 10/3, and absolute minimum is f(0) = 8.
How to determined the absolute extrema?First, let's find the derivative of the function:
f(x) = 8+x/2-x
f'(x) = (1/2) - 1 = -1/2
Next, we need to find the critical points of the function on the given domain.
In this case, the derivative is always defined and is never zero. Therefore, there are no critical points on the given domain.
Next, we check the endpoints of the domain, x = -2 and x = 0:
f(-2) = 8 + (-2)/(2-(-2)) = 10/3
f(0) = 8 + 0/(2-0) = 8
Since the function is continuous on the closed interval [-2, 0],
The extreme value theorem tells us that the function must have both an absolute maximum and an absolute minimum on the interval.
Therefore, the absolute maximum occurs at x = -2 and is f(-2) = 10/3, and the absolute minimum occurs at x = 0 and is f(0) = 8.

Jack claims that QRST is a parallelogram. If m∠R = 72, m∠T = 108, and m∠S = 72, is he correct? Explain
We can conclude that Jack's claim is correct. QRST is indeed a parallelogram, since opposite angles in QRST are congruent, and opposite sides in a parallelogram are also congruent
To determine whether Jack's claim that QRST is a parallelogram is correct, we need to use the properties of parallelograms. One of the properties of a parallelogram is that opposite angles are congruent. Therefore, we need to check if the opposite angles in QRST are congruent.
If m∠R = 72 and m∠T = 108, then the sum of these angles is 180 degrees (72 + 108 = 180). This indicates that angles R and T are supplementary.
If m∠S = 72, then we need to find the measure of angle Q. Since QRST is a quadrilateral, the sum of its interior angles is 360 degrees.
m∠Q + m∠R + m∠S + m∠T = 360
Substituting the given values, we get:
m∠Q + 72 + 72 + 108 = 360
Simplifying the equation, we get:
m∠Q = 108
Therefore, angles Q and S are congruent (both measuring 72 degrees) and angles R and T are supplementary (measuring 72 and 108 degrees, respectively). Since opposite angles in QRST are congruent, and opposite sides in a parallelogram are also congruent, we can conclude that Jack's claim is correct. QRST is indeed a parallelogram.

Determine the equation of the tangent plane to the surface z = y ln x at the point (1, 4, 0)
z = 4(x - 1) - ln (y - 4)
Therefore, the equation of the tangent plane to the surface z = y ln x at the point (1, 4, 0) is z = 4(x - 1) - ln (y - 4).
To determine the equation of the tangent plane to the surface z = y ln x at the point (1, 4, 0), we first need to find the partial derivatives of the surface with respect to x and y.
∂z/∂x = y/x
∂z/∂y = ln x
Then, we can use these partial derivatives along with the point (1, 4, 0) to find the equation of the tangent plane using the formula:
z - z0 = ∂z/∂x(x0, y0)(x - x0) + ∂z/∂y(x0, y0)(y - y0)
where (x0, y0, z0) is the given point.
Plugging in the values, we have:
z - 0 = (4/1)(x - 1) + ln 1(y - 4)
Simplifying:
z = 4(x - 1) - ln (y - 4)
Therefore, the equation of the tangent plane to the surface z = y ln x at the point (1, 4, 0) is z = 4(x - 1) - ln (y - 4).

If p : q = 2/3 : 2 and p : r = 3/4 : 1/2 , calculate the ratio p : q : r Giving your answer in its simplest form.
please help i mark it as brainly
If p : q = 2/3 : 2 and p : r = 3/4 : 1/2 , the ratio of p : q : r in its simplest form is 32 : 27 : 24.
To calculate the ratio p : q : r, we need to first find the values of p, q, and r. We can use the given proportions to set up a system of equations and solve for the variables.
From the first proportion, we know that:
p/q = 2/3 : 2
We can simplify this by cross-multiplying:
p = (2/3) * 2q
p = (4/3)q
From the second proportion, we know that:
p/r = 3/4 : 1/2
Again, we can cross-multiply and simplify:
p = (3/4) * r/(1/2)
p = (3/2)r
Now we have two equations for p in terms of q and r. We can substitute these into each other and solve for q and r:
(4/3)q = (3/2)r
r/q = (8/9)
q/r = (9/8)
Now we have the ratios of r to q and q to r. We can use these to find the ratio of p, q, and r:
p : q : r = p : q * (9/8) : r * (8/9)
Substituting the values we found for p in terms of q and r:
p : q : r = (4/3)q : q * (9/8) : r * (8/9)
Simplifying:
p : q : r = 32 : 27 : 24

Adam is purchasing a new television that costs $2,187. 96 after tax. He borrowed the money from his parents and must pay back the full amount plus simple interest at the rate of 3. 5%. What is the total amount he will pay if he takes 2 years to pay his parents back? (Include Decimal with the cents; No Commas)
please
he interest he will pay if he takes 2 years to pay his parents back is $153.16. The total amount he will pay if he takes 2 years to pay his parents back is $2,341.12.
To calculate the interest Adam will pay, we need to use the simple interest formula:
Interest = Principal x Rate x Time
The principal is the amount borrowed, which is $2,187.96. The rate is 3.5% per year, or 0.035 in decimal form. The time is 2 years.
Interest = $2,187.96 x 0.035 x 2 = $153.16
Therefore, Adam will pay $153.16 in interest if he takes 2 years to pay his parents back.
To calculate the total amount he will pay, we need to add the interest to the principal:
Total amount = Principal + Interest
Total amount = $2,187.96 + $153.16 = $2,341.12
Therefore, Adam will pay a total of $2,341.12 if he takes 2 years to pay his parents back.
