The area of the rectangle is, 24 square centimeter.

What is area?

Area is a mathematical concept that expresses the size of a region on a planar or curved surface. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Let, the perimeter of the rectangle is 20 centimeter.

The length is 6 centimeter.

Suppose the width of the rectangle is y.

So,

Perimeter = 2(6) + 2(y)

           20 = 12 + 2y

             8 = 2y

             y = 4

Hence, the width of the rectangle is 4 centimeter.

Since,

Area of rectangle = length x width

                          A =  6 x 4

                          A = 24

Therefore, the area of the rectangle is, 24 square centimeter.

The general solution to the given differential equation is:

y = (4/(1 + √(1 - y⁴) × \(e^{(1 + \sqrt{(1 - y^4))x/2})\) + C₁x + C₂

where C₁ and C₂ are constants of integration.

To find the general solution to the given differential equation, we can make a substitution to reduce the order of the equation.

Let's assume a new variable u = y".

Therefore, we have:

u' = (d²y/dx²)' = d³y/dx³

u'' = (d³y/dx³)' = d⁴y/dx⁴

Now, we can rewrite the original differential equation in terms of u:

y⁴ - 4y'" + 4y" = 0

y⁴ - 4(d⁴y/dx⁴) + 4(d³y/dx³) = 0

y⁴ - 4u'' + 4u' = 0

Simplifying the equation, we get:

y⁴ + 4u' - 4u'' = 0

Now, we can solve this differential equation for u:

u' - u'' = -y⁴/4

To solve this linear homogeneous differential equation, we assume a solution of the form \(u = e^{mx}\).

Substituting this into the equation, we get:

m\(e^{mx\) - m²\(e^{mx\)  = -y⁴/4

Simplifying further:

m - m² = -y⁴/4

Rearranging the equation, we have:

m² - m + y⁴/4 = 0

This is a quadratic equation in terms of m.

Solving this quadratic equation, we find the roots:

m₁ = (1 ± √(1 - 4y⁴/4)) / 2

= (1 ± √(1 - y⁴)) / 2

Since we assumed \(u = e^{mx}\) we have two linearly independent solutions for u:

\(u_1 = e^{m_1x} = e^{(1 + \sqrt{(1 - y^4))x/2})\)

\(u_2 = e^{m_2x} = e^{(1 - \sqrt{(1 - y^4))x/2})\)

Now, we can find y by integrating u twice:

u = y"

u' = y'

Integrating u' = y', we get:

y' = ∫(u')dx = ∫\(e^{(1 + \sqrt{(1 - y^4))x/2})\)dx

= (2/(1 + √(1 - y⁴))) × \(e^{(1 + \sqrt{(1 - y^4))x/2})\) + C₁

Integrating y' = ∫(y')dx, we get:

y = ∫(2/(1 + √(1 - y⁴)) × \(e^{(1 + \sqrt{(1 - y^4))x/2})\) + C₁ dx

= (4/(1 + √(1 - y⁴) × \(e^{(1 + \sqrt{(1 - y^4))x/2})\) + C₁x + C₂

Therefore, the general solution to the given differential equation is:

y = (4/(1 + √(1 - y⁴) × \(e^{(1 + \sqrt{(1 - y^4))x/2})\) + C₁x + C₂

(A) The probability of selecting one defective component is approximately 0.123.

(B) The probability of selecting at least one non-defective component is approximately 0.999.

(A) To calculate the probability of having one defective component, we need to determine the number of favorable outcomes (selecting one defective bearing) and divide it by the total number of possible outcomes (selecting three bearings without replacement).

Favorable outcomes: Selecting one defective bearing out of the remaining 35 defective bearings (300 total - 265 non-defective).

Total possible outcomes: Selecting three bearings out of the 300 bearings.

Calculating the probability:

P(one defective) = (Number of favorable outcomes) / (Total possible outcomes)

= (35 choose 1) / (300 choose 3)

P(one defective) = (35 * (300-35)) / (300 * 299 * 298 / 3 * 2 * 1)

= 35 * 265 / (300 * 299)

≈ 0.123

The probability of selecting one defective component is approximately 0.123.

(B) To calculate the probability of selecting at least one non-defective component, we can find the complement of the probability of selecting only defective components. In other words, it is the probability that all three selected bearings are defective subtracted from 1.

Probability of selecting all defective components:

P(all defective) = (Number of ways to choose 3 defective bearings) / (Total possible outcomes)

= (35 choose 3) / (300 choose 3)

Calculating the complement probability:

P(at least one non-defective) = 1 - P(all defective)

P(at least one non-defective) = 1 - [(35 * 34 * 33) / (300 * 299 * 298 / 3 * 2 * 1)]

≈ 1 - 0.001

The probability of selecting at least one non-defective component is approximately 0.999.

Therefore , the solution of the given problem of percentage comes out to be 38 years old is the median age.

In statistics, a "a%" is a figure or statistic that is expressed as a percentage of 100. The words "pct," "pct," but instead "pc" are also not frequently used. However, the sign "%" is frequently used to represent it. The percentage sum is flat; there are no dimensions. Percentages are truly integers because their numerator almost always equals 100. Either the % symbol (%) or the additional term "fraction" must come before a number to denote that it is a percentage.

Here,

The following algorithm must be used to determine the mean age:

=> mean = (all years added together) / (total number of persons)

The representative age for each age group is the age that falls in the middle of the range. With this approach, we can determine the total age as follows:

=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)

=> 162 + 644 + 924 + 2970 + 4636 + 2688 + 1152 + 1520 + 272.25

=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)

According to the information provided, there are 460 people in total.

=> mean = 17745.25 / 460

=> mean = 17745.25 / 460

As a result, the average lifespan is roughly 38.552 years.

The age category in this instance with the highest frequency has a midpoint of 38 and a frequency of 122. As a result, 38 years old is the median age.

= 6x⁷ -2x⁶ + 8x⁵

Answer:

A. \(6x^{7} - 2x^{6} + 8x^{5}\)

Label the parts of the expression:

Outside the parentheses = \(2x^{4}\)

Inside parentheses = \(3x^{3} -x^{2} + 4x\)

You must distribute what is outside the parentheses with all the values inside the parentheses. Distribution means that you multiply what is outside the parentheses with each value inside the parentheses

\(2x^{4}\) × \(3x^{3}\)

\(2x^{4}\) × \(-x^{2}\)

\(2x^{4}\) × \(4x\)

First, multiply the whole numbers of each value before the variables

2 x 3 = 6

2 x -1 = -2

2 x 4 = 8

Now you have:

6\(x^{4}x^{3}\)

-2\(x^{4}x^{2}\)

8\(x^{4} x\)

When you multiply exponents together, you multiply the bases as normal and add the exponents together

\(6x^{4+3}\) = \(6x^{7}\)

\(-2x^{4+2}\) = \(-2x^{6}\)

\(8x^{4+1}\) = \(8x^{5}\)

A stratified sample is a type of probability sample where the population is divided into segments related to the study's topic before selecting participants.

In a stratified sample, the researcher divides the population into distinct subgroups or strata based on certain characteristics or variables that are relevant to the study. Each subgroup or stratum represents a smaller, homogeneous subset of the population. The characteristics used to create the strata could be demographic factors such as age, gender, ethnicity, or any other relevant variables.

Once the population is divided into strata, participants are then randomly selected from each stratum using probability sampling techniques. This ensures that the sample obtained is representative of the overall population in terms of the characteristics or variables of interest.

By utilizing a stratified sample, researchers can ensure that each subgroup or stratum is adequately represented in the sample, allowing for more accurate and precise conclusions to be drawn about the entire population. Stratified sampling is particularly useful when there is significant heterogeneity within the population, as it allows for targeted and focused analysis within specific subgroups.

Step-by-step explanation:

The closest option to the calculated net present value is d. $(15,542).

To calculate the net present value (NPV) of the project, we need to discount the annual cash flows to their present value and subtract the initial investment.

Using the formula for the present value of a cash flow:

PV = CF / (1 + r)^n

Where PV is the present value, CF is the cash flow, r is the discount rate, and n is the number of years.

For the given data:

Initial investment = $380,000

Annual cash flow = $133,000 per year

Expected life of the project = 4 years

Discount rate = 13%

Calculating the present value of the annual cash flows:

PV = $133,000 / (1 + 0.13)^1 + $133,000 / (1 + 0.13)^2 + $133,000 / (1 + 0.13)^3 + $133,000 / (1 + 0.13)^4

PV ≈ $133,000 / 1.13 + $133,000 / 1.28 + $133,000 / 1.45 + $133,000 / 1.64

PV ≈ $117,699 + $104,687 + $91,724 + $81,098

PV ≈ $395,208
