(1, −2)
Help I'm stuck with this one :(

Answers

If you want to transform rectangular coordinates (x, y) into its polar counterpart (r, θ), do the following:

The Steps

Firstly, obtain r by computing the distance from the origin to point (x,y), making use of the Pythagorean theorem or simply put, by evaluating r = sqrt(x^2 + y^2).

Secondly, acquire θ which denotes the angle formed between the positive x-axis and a line correlating the origin and the coordinate (x,y). Calculate this via inverse tangent function: θ = atan2(y, x).

Thirdly, in case the measurement for θ is indicated in radians while you require degrees instead, multiply by 180/π to convert it.

Usually expressed as (r, θ), where r indicates proximity disentangled between the origin and the point (x,y), whilst θ identifies the aforementioned angle.

Why do polling companies often survey 1060 individuals when they wish to estimate a population proportion with a margin of error 3% with 95% confidence?

Answers

Polling companies survey 1060 individuals to estimate a population proportion with a margin of error of 3% with 95% confidence because it strikes a balance between cost and accuracy, and it is based on statistical calculations that aim to achieve a reasonable level of precision while minimizing the margin of error.

When a polling company selects a sample size of 1060 individuals, it is based on statistical calculations that aim to achieve a 3% margin of error with 95% confidence. The sample size needs to be large enough to reduce the margin of error and increase the level of confidence in the results.

The margin of error decreases as the sample size increases, and it is inversely proportional to the square root of the sample size. Therefore, a larger sample size leads to a smaller margin of error. However, increasing the sample size also increases the cost and time required to conduct the survey.

Polling companies aim to strike a balance between the cost and the desired level of accuracy, which is typically a margin of error of 3-5% with 95% confidence. A sample size of 1060 individuals is often considered a reasonable compromise between cost and accuracy, as it provides a small enough margin of error to be useful while being feasible to conduct within a reasonable time and budget.

Jan has set the sales target for 35,000 ice cream makers, which she thinks she can achieve by an additional fixed selling expense of $200,000 for advertising. All other costs remain as per the data in the above table. What will be the operating profit if the additional $200,000 is spent on advertising and sales rise to 35,000 units?

Answers

The company would incur a loss of $14,800,000 if it spends an additional $200,000 on advertising to achieve sales of 35,000 units.

What do sales mean?

Sales generally refer to the total amount of goods or services that a business sells during a given period of time, typically measured in monetary terms. Sales can also refer to the process of selling products or services, including activities such as prospecting, lead generation, sales presentations, and closing deals.

According to the given information

To calculate the operating profit with sales of 35,000 units and an additional selling expense of $200,000, we need to first calculate the total revenue and the total cost, and then subtract the total cost from the total revenue.

From the table provided, we can see that the selling price per unit is $900 and the variable cost per unit is $600. Therefore, the contribution margin per unit is:

Contribution margin per unit = Selling price per unit - Variable cost per unit

= $900 - $600

= $300

Since the sales target is 35,000 units, the total contribution margin is:

Total contribution margin = Contribution margin per unit x Number of units sold

= $300 x 35,000

= $10,500,000

The total cost can be calculated as follows:

Total cost = Fixed cost + Variable cost

= $3,500,000 + ($600 x 35,000)

= $25,100,000

Adding the additional selling expense of $200,000, the new total cost becomes:

New total cost = $25,100,000 + $200,000

= $25,300,000

Therefore, the operating profit with sales of 35,000 units and an additional selling expense of $200,000 is:

Operating profit = Total revenue - Total cost

= ($900 x 35,000) - $25,300,000

= $10,500,000 - $25,300,000

= -$14,800,000

This indicates that the company would incur a loss of $14,800,000 if it spends an additional $200,000 on advertising to achieve sales of 35,000 units.

Experiment 4: You have a bag of 15 scrabble tiles. 3 of the
tiles are the letter O. And the other 2 tiles are the letter U.
a. What is the probability of getting an O on the first draw?
b. What is the probability of getting a U if you didn't replace the O?
What is the probability of getting O and then U if you don't
replace the O?
c.

Answers

Answer:

a. The probability of getting an O on the first draw can be calculated by dividing the number of O tiles by the total number of tiles in the bag:

```

P(O on first draw) = 3/15 = 0.2

```

Therefore, the probability of getting an O on the first draw is 0.2 or 20%.

b. After removing one O tile, there are 14 tiles left in the bag, of which 2 are U tiles. Therefore, the probability of getting a U if you didn't replace the O is:

```

P(U without replacing O) = 2/14 = 1/7 ≈ 0.143

```

Therefore, the probability of getting a U if you didn't replace the O is approximately 0.143 or 14.3%.

c. The probability of getting O and then U if you don't replace the O can be calculated as follows:

```

P(O and then U) = P(O on first draw) * P(U without replacing O)

= 3/15 * 2/14

= 1/35

≈ 0.029

```

Therefore, the probability of getting O and then U if you don't replace the O is approximately 0.029 or 2.9%.

Step-by-step explanation:

For a certain company, the cost function for producing x items is C(x)=50x+250
and the revenue function for selling x items is R(x)=−0.5(x−120)2+7,200
. The maximum capacity of the company is 170
items.

Profit when producing 70
items=?
Profit when producing 80
items=?

Can you explain, from our model, why the company makes less profit when producing 10 more units?

Answers

Answer:

Profit when producing 70 items = $3,050

Profit when producing 80 items = $1,350

Step-by-step explanation:

To find the profit when producing a certain number of items, we need to subtract the cost from the revenue:

Profit = Revenue - Cost

Let's calculate the profit for producing 70 items:

Revenue when producing 70 items:

R(70) = -0.5(70-120)^2 + 7,200 = $6,800

Cost of producing 70 items:

C(70) = 50(70) + 250 = $3,750

Profit when producing 70 items:

Profit = Revenue - Cost = $6,800 - $3,750 = $3,050

Similarly, let's calculate the profit for producing 80 items:

Revenue when producing 80 items:

R(80) = -0.5(80-120)^2 + 7,200 = $5,600

Cost of producing 80 items:

C(80) = 50(80) + 250 = $4,250

Profit when producing 80 items:

Profit = Revenue - Cost = $5,600 - $4,250 = $1,350

We can see that the profit is less when producing 10 more units because the cost of producing those additional units exceeds the revenue generated from selling them. In other words, the marginal cost (the cost of producing one additional unit) is greater than the marginal revenue (the revenue generated from selling one additional unit) beyond a certain point.

This is an example of the law of diminishing returns, which states that as we increase the quantity of inputs while keeping other inputs constant, the marginal product (output per unit of input) eventually decreases.

Part A: Calculate the mean, median, mode, and range for the data given. Show your work. (8 points)

Part B: Should the tennis players report the mean or median value to show they are less prepared for the tournament? Explain based on the scenario. (4 points)

Answers

Part A:

To calculate the mean, we add up all the values and divide by the total number of values:

12 + 12 + 19 + 20 + 22 + 26 + 31 + 31 + 40 + 68 = 281

Mean = 281 / 10 = 28.1

To find the median, we need to find the middle value. Since there is an even number of values, we take the average of the two middle values:

Median = (22 + 26) / 2 = 24

The mode is the value that appears most frequently. In this case, there is no mode as no value appears more than once.

The range is the difference between the highest and lowest values:

Range = 68 - 12 = 56

Part B:

The median may be a better measure of central tendency in this scenario as there is an outlier value of 68 that can skew the mean. Since outliers can have a significant impact on the mean, reporting the median may give a better representation of the typical amount of time spent practicing for the tournament. Therefore, the tennis players should report the median value.

Answers

The probability that at least one of the five friends gets her own calculator can be expressed in terms of the events A, B, C, D, and E as follows:

P(at least one gets her own calculator) = 1 - P(none of them get their own calculator)

To calculate P(none of them get their own calculator), we can use the principle of inclusion-exclusion:

P(none of them get their own calculator) = 5!/(5-5)!*(0!)- 4!/(5-4)!*(1!)+ 3!/(5-3)!*(2!)- 2!/(5-2)!*(3!)+ 1!/(5-1)!*(4!)
= 1 - 1 + 10/120 - 15/120 + 24/120
= 8/15

Therefore, the probability that at least one of the five friends gets her own calculator is:

P(at least one gets her own calculator) = 1 - P(none of them get their own calculator)
= 1 - 8/15
= 7/15

Subtract 1 from both sides:

5x + 1 - 1 = 4x + 16 - 15x = 4x + 15

The identity (x² + y²)² = (x² - y²)² + (2xy)²

What is an identity?

An identity is a mathematical equation which shows that one side of the equation is equivalent and equal to the other side of the equation.

To verify the following Pythagorean identity for all values of x and y:

(x² + y²)² = (x² - y²)² + (2xy)², we need to shows that

left-hand side L.H.S = right hand side

So, we proceed as follows

L.H.S = (x² + y²)²

Expanding the brackets, we have that

(x² + y²)² = (x² + y²)(x² + y²)

= (x²)² + 2x²y² + (y²)²

= (x²)² + (y²)² + 2x²y²

Now, we know that (a - b)² = a² + b² - 2ab. So,

a² + b² = (a - b)² + 2ab

Let a = x² and b = y²

So, we have that

(x²)² + (y²)² = (x² - y²)² + 2x²y²

So, substituting this into the equation, we have that

(x²)² + (y²)² + 2x²y² = (x² - y²)² + 2x²y² + 2x²y²

= (x² - y²)² + 4x²y²

= (x² - y²)² + 2²x²y²

= (x² - y²)² + (2xy)²

So, Since L.H.S = R.H.S

(x² + y²)² = (x² - y²)² + (2xy)²

The vertex is the point where the parabola changes direction and is given by the formula x = -b/2a, y = f(x), where f(x) is the value of y at the vertex.

Now let's examine the given options and determine their domain and range based on the graph of the quadratic equation.

all real numbers, R: (y ≤ -4.855)

For this option, we can observe that the parabola opens upward, and the vertex is at (0.7, -5.35).

Find the equation of the plane passing through the lines of intersection of the planes :
2x - 7y + 4z = 3 , 3x - 5y + 4z + 11 = 0 and the point ( -2 , 1 , 3 ).

Answers

The equation of the plane passing through the lines of intersection of the planes 2x - 7y + 4z = 3 and 3x - 5y + 4z + 11 = 0 and the point (-2, 1, 3) is

-13x - 8y + z + 90 = 0

We have,

To find the equation of the plane passing through the intersection of two planes, we need to first find the direction vector of the line of intersection of the two planes.

Let's call the two planes P1 and P2, which are given by the equations:

P1: 2x - 7y + 4z = 3

P2: 3x - 5y + 4z + 11 = 0

To find the direction vector of the line of intersection of P1 and P2, we can take the cross product of the normal vectors of P1 and P2. The normal vectors are:

n1 = <2, -7, 4>

n2 = <3, -5, 4>

Taking the cross-product of n1 and n2.

n1 x n2 = <-13, -8, 1>

This vector is parallel to the line of intersection of P1 and P2. We can use this vector as the direction vector for the line.

Now, we need to find a point on the line.

We can use the point of intersection of P1 and P2 as a point on the line.

To find this point, we can solve the system of equations:

2x - 7y + 4z = 3

3x - 5y + 4z + 11 = 0

Subtracting the first equation from the second, we get:

x + 2y + 7 = 0

Solving for x in terms of y,.

x = -2y - 7

Substituting this expression for x into the first equation, we get:

-4y - 14 - 7y + 4z = 3

Simplifying.

-11y + 4z = 17

Choosing y = 1.

-11 + 4z = 17

Solving for z.

z = 7

Substituting y = 1 and z = 7 into the equation for x.

x = -2(1) - 7 = -9

So a point on the line is (-9, 1, 7).

Now, we can use the point (-9, 1, 7) and the direction vector <-13, -8, 1> to write the equation of the plane passing through the line of intersection of P1 and P2.

Let's call this plane P3.

Using the point-normal form of the equation of a plane.

-13(x + 9) - 8(y - 1) + (z - 7) = 0

Expanding and simplifying, we get:

-13x - 8y + z + 90 = 0

Thus,

The equation of the plane passing through the lines of intersection of the planes 2x - 7y + 4z = 3 and 3x - 5y + 4z + 11 = 0 and the point (-2, 1, 3) is:

-13x - 8y + z + 90 = 0

based on the value of r^2, which modeling equation is best fit for the data set? a. y=16.5839•1.0185^x
b. y=0.985515x-2.81333
c. y=-0.0000758936x^3+0.0143444x^2+0.207549x+7.70667
d. y=0.00182197x^2+0.785098x+1.195

Answers

Okay, let's analyze the r^2 values for the 4 options:

a. y=16.5839•1.0185^x

r^2 is undefined, as this is an exponential model. We cannot determine how well it fits the data based only on r^2.

b. y=0.985515x-2.81333

This is a linear model, so r^2 would be between 0 and 1. Without knowing the actual r^2 value, we cannot determine how good the fit is.

c. y=-0.0000758936x^3+0.0143444x^2+0.207549x+7.70667

This is a 3rd order polynomial model. Again, without the r^2 value, we cannot determine the quality of fit. It could be a good or poor fit.

d. y=0.00182197x^2+0.785098x+1.195

If this model has the highest r^2 value (closest to 1), it would indicate the best fit to the data of the options.

In summary, without seeing the actual r^2 values calculated from the data for each model, we cannot definitively say which option is the "best fit". The model with the r^2 closest to 1 would likely be the best, but r^2 only tells part of the story. Other factors like complexity, interpretability, and residual analysis also matter. But based solely on r^2, the quadratic model d seems the most likely to be the best fit, as long as its r^2 value is high.
