Coefficient Cn is determined by Cn = 1/2 ∫[0,2] (x+2)yn(x) dx

To find the coefficients Cn of the eigenfunction expansion of a function f(x), f(x) must be expanded with the eigenfunction yn(x). The expansion of f(x) with respect to the eigenfunction yn(x) is given by

f(x) = Σ[∞], n=1 cnyn(x)

To find the coefficient cn, we need to compute the dot product of f(x) and yn(x).

cn = (f,yn) = ∫[0,4]f(x)yn(x)dx

Since the eigenfunctions yn(x) are orthonormal, the scalar product is given by

cn = ∫[0,4]f(x)yn(x)dx = ∫[0,2]f(x)yn(x)dx + ∫[2,4]f(x)yn(x)dx

Since f(x) = 2/2 x for x in [0,2] and f(x) = 2 for x in [2,4], compute the coefficient cn as I can do it.

cn = ∫[0,2](2/2x)yn(x)dx + ∫[2,4](2)yn(x)dx

= ∫[0,2]xyn(x)dx + ∫[2,4]2yn(x)dx

= 1/2 ∫[0,2] (xyn(x) + 2yn(x)) dx

= 1/2 ∫[0,2] (x+2)yn(x) dx

Therefore, the coefficient Cn is given by

Cn = 1/2 ∫[0,2] (x+2)yn(x) dx

The phrase that BEST describes humidity is "the amount of water vapor in the air". Therefore, option C is the correct answer.

The phrase that BEST describes humidity is "the amount of water vapor in the air". Humidity is the amount of water vapor in the atmosphere or in a given space. It is a measure of the amount of moisture that is present in the air and is typically expressed as a percentage. This amount of water vapor can be affected by a variety of factors, such as temperature, air pressure, and precipitation.

Therefore, option C is the correct answer.

"Your question is incomplete, probably the complete question/missing part is:"

Which phrase BEST describes humidity?

the amount of precipitation that falls

the temperature of air that causes condensation

the amount of water vapor in the air

the condensation that forms on a cooler surface

We can conclude that with 95 percent confidence, the sample means will fall within the interval of approximately (0.9534, 0.9566).

To determine the interval within which 95 percent of the sample means will fall, we need to calculate the margin of error using the standard deviation and the desired level of confidence.

The formula to calculate the margin of error is given by:

Margin of Error = Z * (Standard Deviation / √n)

Where:

Z is the critical value corresponding to the desired level of confidence

Standard Deviation is the standard deviation of the population

n is the sample size

Since the sample size is 41 and we want to find the interval at a 95 percent confidence level, we need to find the critical value corresponding to a 95 percent confidence level.

The critical value can be found using a standard normal distribution table or a calculator. For a 95 percent confidence level, the critical value is approximately 1.96.

Now we can calculate the margin of error:

Margin of Error = 1.96 * (0.0050 / √41)

Calculating this, we find:

Margin of Error ≈ 0.001624

To find the interval within which 95 percent of the sample means will fall, we need to subtract and add the margin of error to the true mean:

Interval = True Mean ± Margin of Error

Interval = 0.9550 ± 0.001624

Calculating this, we find:

Interval ≈ (0.9534, 0.9566)

Therefore, we can conclude that with 95 percent confidence, the sample means will fall within the interval of approximately (0.9534, 0.9566).

Answer:

Step-by-step explanation:

Answer:

The correct answer is "\(2.633< \sigma < 4.480\)".

Step-by-step explanation:

Given:

n = 21

s = 3.3

c = 0.9

now,

\(df = n-1\)

    \(=20\)

⇒ \(x^2_{\frac{\alpha}{2}, n-1 }\) = \(x^2_{\frac{0.9}{2}, 21-1 }\)

                  = \(31.410\)

⇒ \(x^2_{1-\frac{\alpha}{2}, n-1 }\) = \(10.851\)

hence,

The 90% Confidence interval will be:

= \(\sqrt{\frac{(n-1)s^2}{x^2_{\frac{\alpha}{2}, n-1 }} } < \sigma < \sqrt{\frac{(n-1)s^2}{x^2_{1-\frac{\alpha}{2}, n-1 }}\)

= \(\sqrt{\frac{(21-1)3.3^2}{31.410} } < \sigma < \sqrt{\frac{(21.1)3.3^2}{10.851} }\)

= \(\sqrt{\frac{20\times 3.3^2}{31.410} } < \sigma < \sqrt{\frac{20\times 3.3^2}{10.851} }\)

= \(2.633< \sigma < 4.480\)

The price of the item now is $8 after an 80% reduction. To find the price of the item after the 80% reduction, you can follow these steps:

1. Calculate the amount of the reduction: 80% of $40.

2. Subtract the reduction amount from the original price to get the final price.

Step 1: Calculate the amount of the reduction:

80% of $40 = 0.80 * $40 = $32

Step 2: Subtract the reduction amount from the original price:

Original Price - Reduction Amount = $40 - $32 = $8

So, the price of the item now is $8 after an 80% reduction.

Any polygon can be the base of a prism so the answer is true.

First, add 7 to both sides of the equation so it would be;

2−7 + 7=−5+14+7

To simplify this it would be:

2=−5+21

Add 5 to both sides, it would look like this:

The solution of the expression, \((\frac{2}{3} )^{-4}\) is 81 / 16.

An algebraic expression is an expression which is made up of variables and constants, along with algebraic operations such as multiplication, subtraction, addition etc.

Therefore, lets solve the expression as follows:

\((\frac{2}{3} )^{-4}\)

Using exponential laws,

b⁻¹ = 1 / b

Let's apply the law to the expression as follows:

\((\frac{2}{3} )^{-4} = \frac{1}{(\frac{2}{3})^{4} }\)

Therefore,

A curved line represents the graph of a non-linear function. A curved line is one whose direction changes over time.

Linear refers to straight, and a graph is a figure that depicts the relationship between two or more quantities. So, the simplest definition of a linear graph is a straight line or straight graph constructed on a plane to connect two points with x and y coordinates.

The two-variable linear equation 3x - 7y = 16 has three variables. Instance For the equation 2x + y = 8, Mike must create a linear graph. With a ruler and the specified amount as the starting point, draw a vertical line. From the line across to the -axis, draw a horizontal line using a ruler. Look at the value on the -axis. Examining the information on the graph's plot can help you distinguish between a linear and a quadratic graph.

30 + 110 + 30 + 110 = 280

360-280 = 80

2y = 80

y = 40 degrees

If y is 40. Then the angle next to 30 is also y due to vertically opposite angles.

30 + 40 = 70

The line with 2 arrows is parallel to the line with x degrees. So, I use co-interior angles adds to 180.

In that c shaped, we got the bottom angle to be 70 & the top to be 110 because co-interior angles =180

Forget the c shape exists, and move onto the triangle that's visible. The top angle is 110 as found.

Angles in triangle add to 180.

180 - 110 - 30 = 40.

Thus, x = 40 degrees

There's a short cut I realise now because we can have alternate angles are equal; creating a z shape to find what x is equal to & that turns out to be the same value as y. ( due to vertically opposite angles)

Hope this helps!

Using the same-side interior angles theorem,

\(8x+30+6x+24=180 \\ \\ 14x+54=180 \\ \\ 14x=126 \\ \\ \boxed{x=9}\)

Using vertical angles,

\(6(9)+24=10y+2 \\ \\ 78=10y+2 \\ \\ 10y=76 \\ \\ \boxed{y=7.6}\)

Step-by-step explanation:

Both triangles are similar triangles!

Length 21 for the top triangle is similar to length 20 for the bottom triangle

Length 29 for the top is similar to b on the bottom.

Length 20 for the top is similar to a on the bottom.

Use the first ratio: 21/20 to find the proportionality constant.

Divide 29 by that constant to get b

Divide 20 by that constant to get a

You end up with b = 580/21 (= 27.61), and a = 400/21 (= 19.047)

Therefore A is the right answer.

Divide the shape into a square and a rectangle, multiply 7 by 10, and subtract 10 from 21 to get 11. then multiply 11 by 24. Lastly, add the products together and you get 334 feet squared. Have a good day my friend!

The area of the polygon is: 334 ft²

To find the area of a polygon, decompose the polygon into known shapes and find the area of each shape, then add all.

Thus:

Decomposing the polygon given, we would have rectangle 1 and rectangle 2.

Area of rectangle 1 = length × width = 7 × 10 = 70 ft²

Area of rectangle 2 = length × width = 24 × (21 - 10) = 264 ft²

Area of the polygon = 264 + 70 = 334 ft²
