Therefore, the sample size was approximately 1360 Americans.

In statistics, a sample is a subset of a larger population. It is a representative selection of individuals or objects taken from the population of interest to be studied. Samples are often used in statistical analysis because it is usually impractical or impossible to collect data from the entire population.

Here,

The survey states that 20% of American households own 2 pets, and the survey was conducted on 1000 Americans. Since we are trying to identify the sample size, we can use the formula:

sample proportion = x / n

where x is the number of households that own 2 pets, and n is the sample size.

We are given that 20% of the sample own 2 pets, so we can write:

0.20 = x / n

Multiplying both sides by n, we get:

n * 0.20 = x

Simplifying, we get:

n = x / 0.20

We don't know the value of x, but we can estimate it using the proportion of households that own 2 pets in the entire population. According to a study by the American Pet Products Association, about 68% of American households own at least one pet, and about 40% of pet-owning households own two or more pets. Assuming that these percentages hold true for the survey sample as well, we can estimate that:

x = 0.40 * 0.68 * 1000

= 272

Substituting this value into the equation above, we get:

n = 272 / 0.20

= 1360

25 - 11 / 2 = x

14/2 = x

7 = x

x = 7

The equation representing the above statement is 2x + 11 = 25 and the value of the unknown number, x is 7.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Let x be the unknown number.

The unknown number is first doubled, which is represented as 2x.

Then the doubled number is added to 11, which is represented as 2x + 11.

The resulting number is 25.

So, the equation representing the situation can be represented as,

2x + 11 = 25

Subtracting both sides by 11,

2x = 14

Dividing both sides by 2,

x = 7

Hence the value of the unknown number, x is 7.

The length of AC is 32.

A triangle is a geometric shape that consists of three straight sides and three angles. The three angles of a triangle always add up to 180 degrees. Triangles can be classified based on the length of their sides and the size of their angles.

Since the triangles ABC and DBE are similar, we have:

AB/DB = BC/BE

Substituting the given values, we get:

AB/12 = BC/(BE + 4)

We also have another similar ratio:

AD/DB = AC/BE

Substituting the given values, we get:

24/12 = AC/(BE + 4)

Simplifying this equation, we get:

AC = 2(BE + 4)

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

AB/12 = BC/(BE + 4)

AB/(2(BE + 4)) = BC/(BE + 4)

Simplifying this equation, we get:

AB/2 = BC

Now we have two equations:

AB/2 = BC

AC = 2(BE + 4)

Substituting these expressions into the ratio AD/DB = AC/BE, we get:

24/12 = 2(BE + 4)/(AB/2)

Simplifying this equation, we get:

AB = 48/(BE + 4) * (BE/2 + 2)

Substituting the given value DE = 4, we get:

AB = 48/(BE + 4) * (BE/2 + DE/2)

AB = 24 * BE/(BE + 4)

Now we can substitute this expression for AB into the equation AB/2 = BC to get:

24 * BE/(BE + 4) / 2 = BC

12 * BE/(BE + 4) = BC

Substituting this expression for BC into the equation AC = 2(BE + 4), we get:

AC = 2(BE + 4) = 2 * 16 * (BE + 4)/(BE + 4) = 32

Therefore, the length of AC is 32.

To calculate the monthly lease payment, we need to use the formula:

Monthly Payment = Depreciation + Finance Charge

The depreciation represents the portion of the car's value that is lost during the lease period, while the finance charge is the interest charged on the lease.

First, let's calculate the depreciation:

MSRP = $51,500

Residual Value = 49% of MSRP = 0.49 x $51,500 = $25,235

Depreciation = (Negotiated Price - Residual Value - Down Payment) / Lease Term

Depreciation = ($49,000 - $25,235 - $4,000) / 36 = $541.53

Next, let's calculate the finance charge:

Lease Balance = (Negotiated Price - Down Payment) - Residual Value

Lease Balance = ($49,000 - $4,000) - $25,235 = $19,765

Money Factor = Annual Interest Rate / 2400

Money Factor = 7.8% / 2400 = 0.00325

Finance Charge = Lease Balance x Money Factor

Finance Charge = $19,765 x 0.00325 = $64.26

Finally, we can calculate the monthly payment:

Monthly Payment = Depreciation + Finance Charge

Monthly Payment = $541.53 + $64.26 = $605.79

Therefore, the monthly lease payment is $605.79.

0.33 is the approximate experimental probability of landing on B or C.

The actual outcome of an experiment, which may differ from the theoretical probability, is known as experimental probability.

Consider an experiment where 100 coin flips are performed. Theoretically, the odds are 50% heads and 50% tails. Your experiment's true results might be 47 heads and 53 tails.

We have this table

outcome  A     B     C      D

frequency 20  11     14   30

The values in the bottom row add to 20+11+14+30 = 75, so that matches up with the fact that the spinner was spun 75 times. Of those 75 spins, 11+14 = 25 landed on either B or C.

The width of the walkway around the rectangular garden should be approximately 2.061 feet wide.

What is rectangle?

A rectangle is a type of quadrilateral with four sides and four right angles (90-degree angles). It is characterized by two pairs of parallel sides of equal length.

Let's represent the width of the brick walkway by "x" feet.

Then the dimensions of the entire rectangle including the brick walkway will be [tex]$(25+2x)$[/tex] feet by [tex]$(13+2x)$[/tex] feet.

The area of the rectangle with the walkway will be:

[tex]$$(25+2x)(13+2x)$$[/tex]

We know that the area of the walkway itself is 287 square feet. So we can set up the following equation:

[tex]$$(25+2x)(13+2x) - 25\cdot 13 = 287$$[/tex]

Simplifying and solving for x, we get:

[tex]$$4x^2 + 86x - 216 = 0$$[/tex]

Using the quadratic formula, we get:

[tex]$x = \frac{(-86 \pm \sqrt{86^2 - 4(4)(-216)})}{2(4)}$$[/tex]

[tex]$$x \approx 2.061 \text{ or } x \approx -26.311$$[/tex]

Since the width of the walkway cannot be negative, we reject the negative solution. Therefore, the width of the walkway should be approximately 2.061 feet wide (rounded to the nearest thousandth).

In circulation is 6% cumulative preferred stock for ABC Corporation. ABC distributed a 6% preferred dividend two years ago. ABC distributed a 4% preferred stock dividend last year. The minimum payout to preferred stockholders is 8%.

As per the given information, ABC Company has outstanding 6% cumulative preferred stock. This means that the preferred shareholders are entitled to receive a dividend at a fixed rate of 6% every year before any dividend is paid to the common shareholders.

The term "cumulative" implies that any unpaid dividends from previous years must be paid before any dividends can be paid to the common shareholders.

Now, we are given that two years ago, ABC paid a 6% preferred dividend. This means that the preferred shareholders received their full dividend payment for that year.

ABC distributed a 4% preferred stock dividend last year. This means that the preferred shareholders did not receive their full dividend payment for that year, and there is an unpaid amount of 2% (6% - 4%) from the previous year.

Since the preferred stock is cumulative, the unpaid dividends from the previous year must be paid before any dividend is paid to the common shareholders. Therefore, this year, ABC must pay the preferred shareholders their full dividend of 6% for the current year, as well as the unpaid amount of 2% from the previous year, totalling 8%.

As a result, the anticipated value in this circumstance is -$1,750, which probability suggests that if the architect decides to bid on the design of the new museum, she can expect to lose $1,750 on average.

Probability is a measure of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing a rare event and 1 representing an inescapable event. Switching a fair coin and coin flips has a chance of 0.5 or 50% since there are two equally likely outcomes. (Heads or tails). Probabilistic theory is an area of mathematics that studies random events rather than their attributes. It is applied in many disciplines, including statistics, economics, science, and engineering.

0.15 x $45,000 = $6,750.

Consider the following scenario in which the architect is not granted the contract:

The likelihood of not winning the bid is 0.85.

In this case, the payback is -$10,000 (a negative value since the architect would lose the $10,000 cost of creating blueprints and presenting a model).

In this case, the anticipated value is:

0.85 x (-$10,000) = -$8,500.

We sum the anticipated values of both situations to determine the overall expected value:

$6,750 + (-$8,500) = -$1,750.

As a result, the anticipated value in this circumstance is -$1,750, which suggests that if the architect decides to bid on the design of the new museum, she can expect to lose $1,750 on average.

Answer:

Step-by-step explanation:

If the value of the tent depreciates by 12% each year, then its value at the end of each year is 100% - 12% = 88% of its value at the beginning of the year.

So after the first year, the value of the tent will be:

$866 x 0.88 = $761.28

After the second year, the value of the tent will be:

$761.28 x 0.88 = $670.58

After the third year, the value of the tent will be:

$670.58 x 0.88 = $590.99

Therefore, the tent will be worth $590.99 in 3 years, to two decimal places.

Answer:

After one year, the value of the tent will be worth 100% - 12% = 88% of its original value.

After two years, the value of the tent will be worth 88% - 12% = 77.44% of its original value.

After three years, the value of the tent will be worth 77.44% - 12% = 68.1472% of its original value.

To find out how much the tent will be worth in 3 years, we can use the following formula:

Value after 3 years = original value x (1 - depreciation rate)^number of years

Value after 3 years = $866 x (1 - 0.12)^3 = $518.98

Therefore, the tent will be worth $518.98 in 3 years.
