Answer:  $4,000

Step-by-step explanation:

If the total earnings were $40,000 and the base pay was $10,000, then the commission earned would be $40,000 - $10,000 = $30,000.

Since the commission rate is 40%, we can set up the equation:

40% x Total Sales = Commission Earned

We know that the commission earned is $30,000, and we also know that 15 cars were sold. Therefore, we can solve for the average price of each car:

40% x Total Sales = Commission Earned

40% x (15 x Price per Car) = $30,000

6 x Price per Car = $30,000

Price per Car = $5,000

However, this is just the average price per car. Since the commission is based on the total sales, we need to calculate the actual commission earned on each car:

Commission per Car = 40% x Price per Car

Commission per Car = 40% x $5,000

Commission per Car = $2,000

Therefore, the total earnings of $40,000 divided by the number of cars sold (15) gives the amount earned per car:

Amount earned per Car = Total Earnings / Number of Cars Sold

Amount earned per Car = $40,000 / 15

Amount earned per Car = $4,000

The equation for the area in terms of x gives the function David should

use to maximize the area.

Response:

The equation that David should use to help him maximize the area is option A.

The given parameter are;

Length of fencing David has = 400 yards

Area to be enclosed = Rectangular area with pre-existing fence (on one side)

Required:

The equation David should use to maximize the area.

Solution:

Let x represent the width of the area (the sides perpendicular to the pre-

existing fence), and let y represent the length of pre-existing fence

We have;

Length of fencing available = Opposite side to pre-existing fence + 2 × Width of the area

Opposite side to pre-existing fence = Length of pre-existing fence

Which gives;

Length of fencing available = Length of pre-existing fence + 2 × Width of the area

400 = y + 2·x

y = 400 - 2·x

Area = Length × Width

Which gives;

Area = y × x

Area as a function of x is therefore;

Area, f(x)= (400 - 2·x) × x

Which gives;

The correct option is therefore;

Answer:

the probability that either event will occur is 0.92

Step-by-step explanation:

the probability that either event will occur is 0.92

What is the probability that either event will occur?

From the question, we have the following parameters that can be used in our computation:

Event A = 18

Event B = 15

Other Events = 3

Using the above as a guide, we have the following:

Total = A + B + C

So, we have

Total = 18 + 15 + 3

Evaluate

Total = 36

So, we have

P(A) = 18/36

P(B) = 15/36

For either events, we have

P(A or B) = 33/36 = 0.91666

Hence, the probability that either event will occur is 0.92 (rounded to nearest hundreth)

The MAD of the portions of popped balloons is 0.046.

The Mean Absolute Deviation (MAD) is a measure of the average distance between each data point and the mean of the data set. It gives an idea of how spread out the data is around the mean.

To find the mean, median, and MAD (mean absolute deviation) of the given data, we first need to find the average value of the portions of popped balloons.

Mean = (16% + 2/25 + 0.06 + 1/50 + 0.12 + 0.04) / 6

Mean = 0.0975

Therefore, the mean of the portions of popped balloons is 0.0975.

To find the median, we need to first arrange the portions in ascending order:

0.04, 0.06, 1/50, 2/25, 0.12, 16%

Median = (1/50 + 0.06) / 2

Median = 0.035

Therefore, the median of the portions of popped balloons is 0.035.

To find the MAD, we first need to find the absolute deviations of each portion from the mean. We can do this by subtracting the mean from each portion and taking the absolute value:

|0.16 - 0.0975| = 0.0625

|2/25 - 0.0975| = 0.0525

|0.06 - 0.0975| = 0.0375

|1/50 - 0.0975| = 0.0475

|0.12 - 0.0975| = 0.0225

|0.04 - 0.0975| = 0.0575

The MAD is the average of these absolute deviations:

MAD = (0.0625 + 0.0525 + 0.0375 + 0.0475 + 0.0225 + 0.0575) / 6

MAD = 0.046

Therefore, the MAD of the portions of popped balloons is 0.046.

https://brainly.com/question/28276953

Answer:

Step-by-step explanation

1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.

Now let's check if this result is correct:

1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.

So we have shown that each family paid **Rs 13,522** for the trip

The statement that explains how you could use coordinate geometry to prove that quadrilateral ABCD is a square is:

1. Prove that all sides are congruent, and the slopes of consecutive sides are opposite reciprocals.

To prove that quadrilateral ABCD is a square, we need to demonstrate several properties. Let's examine the statement mentioned:

Prove that all sides are congruent, and the slopes of consecutive sides are opposite reciprocals.

First, let's calculate the lengths of the sides of quadrilateral ABCD using the distance formula:

Length of AB = √[(x2 - x1)^2 + (y2 - y1)^2]

= √[(1 - (-3))^2 + (7 - 5)^2]

= √[4^2 + 2^2]

= √[16 + 4]

= √20

= 2√5

Length of BC = √[(x2 - x1)^2 + (y2 - y1)^2]

= √[(3 - 1)^2 + (3 - 7)^2]

= √[2^2 + (-4)^2]

= √[4 + 16]

= √20

= 2√5

Length of CD = √[(x2 - x1)^2 + (y2 - y1)^2]

= √[(-1 - 3)^2 + (1 - 2)^2]

= √[(-4)^2 + (-1)^2]

= √[16 + 1]

= √17

Length of DA = √[(x2 - x1)^2 + (y2 - y1)^2]

= √[(-3 - (-1))^2 + (5 - 1)^2]

= √[(-2)^2 + 4^2]

= √[4 + 16]

= √20

= 2√5

We can observe that all sides AB, BC, CD, and DA have the same length, 2√5. Therefore, all sides of quadrilateral ABCD are congruent.

Next, let's calculate the slopes of the line segments AB, BC, CD, and DA:

Slope of AB = (7 - 5) / (1 - (-3)) = 2/4 = 1/2

Slope of BC = (3 - 7) / (3 - 1) = -4/2 = -2

Slope of CD = (1 - 3) / (-1 - 3) = -2/(-4) = 1/2

Slope of DA = (5 - 1) / (-3 - (-1)) = 4/(-2) = -2

We can observe that the slopes of consecutive sides AB and BC, as well as CD and DA, are opposite reciprocals of each other (1/2 and -2, -2 and 1/2). This satisfies the condition of opposite reciprocals.

Based on the analysis above, we find that all sides of quadrilateral ABCD are congruent, and the slopes of consecutive sides are opposite reciprocals. Therefore, we can conclude that quadrilateral ABCD is a square.

The solution to the inequality √3r + 5 > 1 is r > 16/3.

To solve the inequality √3r + 5 > 1, we can follow these steps:

Subtract 5 from both sides of the inequality:

√3r + 5 - 5 > 1 - 5

√3r > -4

Square both sides of the inequality to eliminate the square root:

(√3r)^2 > (-4)^2

3r > 16

Divide both sides of the inequality by 3 to solve for r:

(3r)/3 > 16/3

r > 16/3

Therefore, the solution to the inequality √3r + 5 > 1 is r > 16/3.

Foreign direct investment helps improve the economic situation of a recipient country by increasing employment opportunities in the country that the company invests in.

When foreign companies invest in a recipient country, they often establish or expand their operations, which requires hiring local workers. This leads to job creation and reduces unemployment rates in the recipient country.

Increased employment opportunities result in more individuals having access to income and improved standards of living.

Foreign direct investment also contributes to the transfer of technology, knowledge, and skills to the recipient country. Multinational companies often bring advanced technologies, production techniques, and management practices that may not have been available or widely adopted in the recipient country.

Furthermore, foreign direct investment stimulates domestic investment and encourages the growth of local businesses. When foreign companies invest in a recipient country, they often form partnerships or engage in supply chain relationships with local firms.

Overall, foreign direct investment increases employment opportunities, fosters technology transfer, and stimulates domestic investment, all of which contribute to improving the economic situation of a recipient country.
