At a charity fundraiser, each female attendant donated $1,200 and each male attendant donated $800. If the average donation at the fundraiser was $900, what was the ratio of the number of female attendants to the number of male attendants.

The error of posting $50 as $500 can be detected by comparing the recorded amount to the expected amount. Here are the steps to detect this error:

1. Calculate the expected amount: Determine the correct amount that should have been posted. In this case, the expected amount is $50.

2. Compare the recorded amount with the expected amount: Check the posted amount and compare it to the expected amount. If the recorded amount shows $500 instead of $50, then an error has occurred.

3. Identify the discrepancy: Recognize that the recorded amount of $500 is significantly higher than the expected amount of $50.

4. Investigate the source of the error: Look for the cause of the error. It could be a data entry mistake, a typo, or a misunderstanding.

5. Take corrective actions: Once the error is detected, rectify it by posting the correct amount of $50. Additionally, ensure that the source of the error is addressed to prevent similar mistakes in the future.

By following these steps, the error of posting $50 as $500 can be detected, corrected, and prevented from happening again.

  y -3 = 1/2(x -4)

The share of Ram is 720, the share of Shyam is 480 and the share of Hari is 360.

Given that, divide 1560 for Ram, Shyam and Hari at ratio 1/2 : 1/3 : 1/4.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Here, 1/2 x + 1/3 x + 1/4 x = 1560

(6x+4x+3x)/12 = 1560

13x/12 = 1560

13x = (1560×12)

13x = 18720

x = 18720/13

x = 1440

Ram = 1/2 ×1440

= 720

Shyam = 1/3 ×1440

= 480

Hari = 1/4 ×1440

= 360

Therefore, the share of Ram is 720, the share of Shyam is 480 and the share of Hari is 360.

Answer:  

Equation translates to 289 + y = 206

it solves to y = -83

====================================================

Explanation:

The "and y more" means we are adding y onto 289 to get the expression 289+y. This is set equal to 206 because of the term "is" in the original statement.

Therefore, "289 and y more is 206" translates fully to the equation 289+y = 206

This is the same as saying y+289 = 206

To isolate y, we undo what is happening to it. We are adding 289 to it, so we must subtract 289 from both sides

y+289 = 206

y+289-289 = 206-289

y = -83

So we are adding -83 to 289 to get 206

Answer:

Quadrants I and II

Step-by-step explanation:

y = x²

y = 3x + 10

x² = 3x + 10                     Substitute x² for y

x² - 3x - 10 = 0                 set the equation = 0

(x - 5) (x + 2)                     Factoring

x - 5 = 0 ; x + 2 = 0

x = 5 or x = -2

Now solving the y

y = x²     or     y = x²

y = (5)²   or y = (-2)²  

y = 25   or  y = 4

The points of interception is points (5, 25) or (-2, 4)  

(5, 25)  in Quadrant I ; (-2, 4) in Quadrant II

The innovation that was made possible in part because of the Carterfone decision in 1968 is the public Internet. The correct answer is option C

The Carterfone decision was a landmark ruling by the Federal Communications Commission (FCC) that allowed for the interconnection of third-party devices to the telephone network. Prior to this decision, telephone companies had a monopoly on the equipment that could be used on their networks, and customers were not allowed to attach their own devices.

This decision paved the way for the development of the public Internet by allowing for the interconnection of third-party devices to the telephone network, which enabled the creation of new technologies, such as modems. Without the Carterfone decision, the public Internet as we know it today may not have been possible.

Step-by-step explanation:

first of all, remember for life :

the sum of all angles in a triangle is always 180°.

so, in this right-angled triangle we have therefore

180 = b + 90 + 71

b = 180 - 90 - 71 = 19°

and then regarding a and b :

the sum of all angles around a single point on one side of a line is also always 180°.

why ? because the line can be seen as the extended diameter of a circle, with that point being the center of the circle. and one side of the line is representing half of that circle. and a half-circle is 180°.

so,

a + b = 180

a + 19 = 180

a = 180 - 19 = 161°

FYI, the reason for the first principle (all angles in a triangle are together 180°) is also based on a half-circle concept : any right-angled triangle can be seen as inscribed into a half-circle, with the Hypotenuse (the baseline opposite of the 90° angle) being the diameter of the circle, and the center of the circle being the midpoint of the Hypotenuse.

We can use the observable data to estimate the parameters consistently.

(a) Simultaneity issue in SEM: The main issue with SEM (simultaneous equation model) is that the endogenous variable is not independent of the error term. Here, the variables (x1, 72, 73, 4) are exogenous variables and (1.2) are endogenous variables.

When an endogenous variable is a function of another endogenous variable, we refer to this as simultaneity.

One example of simultaneity is when the price of a good and the demand for that good are mutually dependent.

If demand for a good is high, the price increases and vice versa, which leads to the issue of simultaneity in the equation.(b) Reduced form equations for 1 and 2:

To get reduced form equations for 1 and 2, we need to eliminate endogenous variables.

x3 = 2x2 is given, let us put it in the equation to get:3/1 = 013/2 + 0271 + 03x2 + 1 + U1

=> 3/1 = (0.13 + 0.27(2x2)) + 03x2 + 1 + U1

=> 3/1 = (0.13 + 0.54x2) + 1 + U1

=> 3/1 = 1.13 + 0.54x2 + U1

=> 1 = -3/1.13 - 0.54x2 - U1/1

Where the coefficients on x2 and U1 are identifiable.

1/2 = 3₁3₁ + 8₂x1 + 3x3 + ₁x₁ + U2₁ =>

1/2 = 3(0.13 + 0.27(2x2)) + 8x1 + 3x3 + 1 + U2

=> 1/2 = 0.39 + 0.81x2 + 8x1 + 3x3 + 1 + U2

=> 0.5 = 0.39 + 0.81x2 + 8x1 + 3x3 + 1 + U2

=> 0.11 = 0.81x2 + 8x1 + 3x3 + U2/2

Where the coefficients on x2, x1, x3, and U2 are identifiable.

(c) Identification of the two structural equations:

We can use the observable data to estimate the parameters consistently when we have a set of equations that are just identified or overidentified.

However, if we have an under-identified model, we cannot estimate the parameters consistently.

To check for identification, we need to check the rank of the matrix.

When we have a linear relationship between 2 and 3, the matrix rank is 2, which means we have two equations and two endogenous variables, and hence the model is just identified.

Therefore, we can use the observable data to estimate the parameters consistently.

To find the new price of the picture frame, we need to use the information that the shop increases all their prices by 9% and the fact that the picture frame increased by £621.

We can start by using the following formula:

New Price = Original Price + (Original Price x Percentage Increase)

Let's let the original price of the picture frame be P. We know that the percentage increase is 9%, which can be written as 0.09 in decimal form. We also know that the picture frame increased by £621, so we can set up the equation:

P + (P x 0.09) = P + £621

Now we can solve for P:

P + 0.09P = P + £621

0.09P = £621

P = £621 ÷ 0.09

P = £6,900

Therefore, the new price of the picture frame is £6,900.

Answer:

A

Step-by-step explanation:

To determine which boxplot (a, b, or c) corresponds to a sample with a range of 21, an interquartile range of 11, and a median of 14, we need to understand the characteristics of a boxplot.

A boxplot provides a visual representation of the distribution of a dataset, displaying key statistics, including the median, interquartile range (IQR), and range.

In mathematics and computer programming, an expression is a combination of numbers, variables, mathematical operations (such as addition, subtraction, multiplication, division, exponentiation, etc.), and sometimes functions. Expressions are used to represent calculations or relationships between different quantities.

The range is the difference between the maximum and minimum values in the dataset.

The interquartile range (IQR) is the range between the first quartile (Q1) and the third quartile (Q3). It represents the middle 50% of the data.

The median is the value that separates the lower 50% of the data from the upper 50%.

Based on the given information:

Range = 21

Interquartile Range (IQR) = 11

Median = 14

We can now compare these values to the characteristics of each boxplot (a, b, and c) and determine which one is the correct representation.

Without seeing the actual boxplots or having more information, it is challenging to give a definitive answer. However, we can make some observations based on the provided information:

If the median is 14, the boxplot should have the median line (box) around the value of 14.

The length of the box (the IQR) should be approximately 11 units.

The whiskers of the boxplot (lines extending from the box) should be around 21 units in length to match the range of 21.

If one of the boxplots satisfies these conditions, that would be the correct answer. If none of the boxplots matches the criteria, it's possible that there's missing or insufficient information to make a definitive determination.

a. The price of the consol is approximately $133.33.

b. The new price of the consol would be $100. The price of the consol falls by 24.99% and the interest rate rises by 1%.

c. Your holding period return is approximately -49.99%.

a. The price of the consol can be calculated using the formula for the present value of a perpetuity:

Price = Annual Payment / Interest Rate

In this case, the annual payment is $4 and the interest rate is 3%. Substituting these values into the formula:

Price = $4 / 0.03 ≈ $133.33

Therefore, the price of the consol is approximately $133.33.

b. To calculate the new price of the consol if the interest rate rises to 4%, we use the same formula:

New Price = Annual Payment / New Interest Rate

Substituting the values, we get:

New Price = $4 / 0.04 = $100

The percentage change in the price of the consol can be calculated using the formula:

Percentage Change = (New Price - Old Price) / Old Price * 100

Substituting the values, we have:

Percentage Change in Price = ($100 - $133.33) / $133.33 * 100 ≈ -24.99%

The percentage change in the interest rate is simply the difference between the old and new interest rates:

Percentage Change in Interest Rate = (4% - 3%) = 1%

Comparing the two percentages, we can see that the price of the consol falls by approximately 24.99%, while the interest rate rises by 1%.

c. The holding period return can be calculated using the formula:

Holding Period Return = (Ending Value - Initial Value) / Initial Value * 100

The initial value is the purchase price of the consol, which is $133.33, and the ending value is the price of the consol after one year with an interest rate of 6%. Using the formula for the present value of a perpetuity, we can calculate the ending value:

Ending Value = Annual Payment / Interest Rate = $4 / 0.06 = $66.67

Substituting the values into the holding period return formula:

Holding Period Return = ($66.67 - $133.33) / $133.33 * 100 ≈ -49.99%

Therefore, the holding period return is approximately -49.99%.

Option A is incorrect because having two y-values that are the same does not necessarily disqualify a relation from being a function. What matters is that each x-value corresponds to exactly one y-value.

Option B is incorrect because it describes the property of a relation having a domain that includes all the given x-values, but it does not guarantee that each x-value has a unique y-value.

Option C is incorrect because it describes a situation where one x-value has multiple corresponding y-values, which violates the definition of a function.
