Given that the random variables X and Y have a joint pdf of (1/5)(11x^2 4y^2).We have to find E(Y).Formula used: E(Y) = ∫∫yf(x,y)dxdyLimits of integration:

x from 0 to 1 and y from 0 to 2 Solution:We have the joint pdf of X and Y as (1/5)(11x^2 4y^2).∴ f(x,y) = (1/5)(11x^2 4y^2)To calculate E(Y), we need to integrate Y * f(x,y) w.r.t X and Y.E(Y) = ∫∫yf(x,y)dxdyPutting the value of f(x,y), we getE(Y) = ∫∫y(1/5)(11x^2 4y^2) dxdy... (1)

Limits of x is 0 to 1 and y is 0 to 2.∴ ∫∫y(1/5)(11x^2 4y^2) dxdy= (1/5)∫[0,2]∫[0,1]y(11x^2 4y^2)dxdy = (1/5)∫[0,2]((11x^2)/3)y^3∣[0,1]dy∴ E(Y) = (1/5) ∫[0,2] [(11/3)y^3] dy= (11/15) [(1/4)y^4] ∣[0,2]= (11/15) [(1/4)(16)] = 1.466 (rounded off to three decimal places)Therefore, the expected value of Y is 1.466.

Step-by-step explanation:

Based on the given data, we can calculate the control limits using 3-sigma for the diameter of the auto pistons.

a) The value of x is 155.56 mm (rounded to two decimal places).

b) The value of R is 4.44 mm (rounded to two decimal places).

c) Using 3-sigma, the Upper Control Limit (UCL) for the diameter is calculated as:

UCL = x + 3R = 155.56 + 34.44 = 156.93 mm (rounded to two decimal places)

The Lower Control Limit (LCL) for the diameter is calculated as:

LCL = x - 3R = 155.56 - 34.44 = 154.19 mm (rounded to two decimal places)

d) Using 3-sigma, the Upper Control Limit for the Range (UCLR) is calculated as:

UCLR = D4 * R = 2.115 * 4.44 = 7.89 mm (rounded to two decimal places)

The Lower Control Limit for the Range (LCLR) is always 0 in this case since negative ranges are not possible.

e) If the true diameter mean should be 155 mm, the new centerline (nominal line) would be 155 mm. In this case, the UCL and LCL would be calculated using 3-sigma as follows:

UCL = Nominal + 3R = 155 + 34.44 = 156.37 mm (rounded to two decimal places)

LCL = Nominal - 3R = 155 - 34.44 = 153.63 mm (rounded to two decimal places)

Please note that the control limits calculated using 3-sigma assume a normal distribution and the data follows the same pattern in the future.

Answer:

6 cm and 18 cm.

Step-by-step explanation:

We are given that:

The perimeter of any rectangle is:

To determine the dimensions of the rectangle, we need to determine the value of "x". The word "dimensions" are the length and the width of the rectangle. Since the question has not stated the length and width, we can consider the length as x and the width as 3x.

It is also given that the perimeter of the rectangle is 48 cm. Thus, the formula with the length and the width substituted is equivalent to 48 cm.

It is required for the expression on the left hand side to be simplified. This can be done by combining like terms.

Then, we can divide 8 both sides to isolate the coefficient from "x". Once the coefficient of "x" is isolated, we will obtain the value of "x".

Finally, substitute the value of "x" into the length and the width. We considered the length to be "x" and the width to be "3x". Therefore,

Thus, the dimensions of the rectangle are 6 cm and 18 cm.

Step-by-step explanation:

A linear equation in two variables can be described as a linear relationship between x and y, that is, two variables in which the value of one of them (usually y) depends on the value of the other one (usually x). In this case, x is the independent variable, and y depends on it, so y is called the dependent variable

The value of a negative number such that the sum of that number and its square is 42 is -7.

Let the negative number be -x.

According to the question, the sum of the negative number and its square is 42.

So, we form an equation

- x + (-x)² = 42

x² - x - 42 = 0

Solving the quadratic equation,

x² - 7x + 6x - 42 = 0

x(x - 7) + 6(x - 7) = 0

(x - 7)(x + 6) = 0

x = -6 and x = 7

We have taken the number -x to be negative.

So, -x = -6 and -x = 7

x = 6 and x = -7

Hence, the value of the negative number is -7.

To duplicate angle ABC, draw a line segment, position the compass on point A, and then draw an arc that intersects the line segment. Next, position the compass on point B, and then draw a second arc that intersects the first arc at a point on the line segment. Finally, position the compass on the point where the two arcs intersect, but without changing the width, and draw a third arc that intersects the line segment.

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.

Common instruments used to measure angles are:

1. Protractor

2.Compass

3.Digital Angle finder

4.Angle finder

5.Clinometer

6. Inclinometer

You can take the following actions to copy angle ABC:

Create a line segment that will serve as the foundation for the new angle you're going to create.

Draw an arc that crosses the line segment you produced in step 1 by positioning the compass on point A.

Draw a second arc that crosses the previous arc at a point on the line segment by setting the compass on point B.

Place the compass on the intersection of the two arcs without adjusting the compass's width, then create another arc that crosses the line segment.

Point D is where the second arc crosses the line segment. To finish the new angle, join points D and C.

The Kutta-Joukowski theorem, which is represented by equation (3.140), was originally derived for the case of a lifting cylinder. However, it can also be applied to a two-dimensional body of arbitrary shape, as stated in section 3.16.

A more detailed explanation of the answer.
To make a physical argument for this generalization, we can draw a closed curve around the body.

The key is to draw the curve far enough away from the body such that the body appears as a very small speck in the middle of the domain enclosed by the closed curve.

By doing this, we are essentially treating the body as a point object at the center of the curve. Since the body is now a very small speck in comparison to the large domain, its specific shape becomes insignificant to the overall flow around it.

Therefore, the lifting force calculations derived from the Kutta-Joukowski theorem for the lifting cylinder should also apply to the two-dimensional body of arbitrary shape, as long as the body is small in comparison to the domain enclosed by the closed curve.

This physical argument allows us to accept that equation (3.140) can be applied in general to a two-dimensional body of arbitrary shape without requiring a mathematical proof.

The functional need for touch (NFTs) refers to individuals using touch to evaluate products, while the hedonic need for touch (NFTs) refers to individuals touching things because they find the tactile sensation pleasurable.

The functional need for touch (NFTs) is rooted in the practical aspect of touch. It pertains to individuals utilizing the sense of touch to evaluate products. When evaluating products, people often rely on tactile feedback to assess qualities such as texture, material, weight, and durability.

On the other hand, the hedonic need for touch (NFTs) is driven by the pleasurable sensation of touching objects.

Some individuals simply enjoy the tactile experience itself, finding pleasure in the sensation of running their fingers over different surfaces, textures, or shapes.

This pleasure-seeking aspect of touch can be soothing, comforting, or even arousing for some people. It can range from appreciating the smoothness of a polished stone to the satisfying feedback of pressing a button on a mechanical keyboard.

The probability that the sample mean will be greater than 57.95 is 0.0495.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. This is the basic probability theory, which is also used in the probability distribution.

To solve this question, we need to know the concepts of the normal probability distribution and of the central limit theorem.

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z=\dfrac{X-\mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The Central Limit Theorem establishes that, for a random variable X, with mean \(\mu\) and standard deviation \(\sigma\), a large sample size can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(\frac{\sigma}{\sqrt{\text{n}} }\).

In this problem, we have that:

The probability that the sample mean will be greater than 57.95

This is 1 subtracted by the p-value of Z when X = 57.95. So

\(Z=\dfrac{X-\mu}{\sigma}\)

By the Central Limit Theorem

\(Z=\dfrac{X-\mu}{\text{s}}\)

\(Z=\dfrac{57.95-53}{3}\)

\(Z=1.65\)

\(Z=1.65\) has a p-value of 0.9505.

Therefore, the probability that the sample mean will be greater than 57.95 is 1-0.9505 = 0.0495

Ordered pairs of points that can be plotted to graph are (-1,1),(1,5).

The correct option is (b).

A graph is a structure made up of a collection of things where some object pairs are conceptually "connected." Each pair of connected vertices is known as an edge, and the items are represented by mathematical abstractions called vertices (also known as nodes or points) (also called a link or line). In a diagram, a graph is often represented by a group of dots or circles for the vertices and lines or curves for the edges. Graphs are one of the subjects covered in discrete mathematics. Both directed and undirected edges are possible. The fundamental topic of graph theory is graphs.

Calculation:

We have to find the ordered pair of points that can be plotted to graph of 6x - 3y = -9

By putting x =  -1

⇒ -6 - 3y = -9

⇒ 3 = 3y

⇒ y = 1

By putting x = 0

⇒ -3y = -9

⇒ y = 3

By putting x = 1

⇒ 6 - 3y = -9

⇒ 15 = 3y

⇒ y =  5

So, the ordered pairs obtained are (-1,1),(0,3) and (1,5).

Hence, the correct option is (b)

The measure of angle m∠W of the triangle is m∠W= 29°

Given data:

To find the measure of angle W (m∠W), use the fact that the sum of angles in a triangle is 180°.

m∠V + m∠W + m∠X = 180°

Substituting the given angle measures:

(6x - 4) + (x + 12) + (3x + 2) = 180°

Simplifying the equation:

6x - 4 + x + 12 + 3x + 2 = 180

Combining like terms:

10x + 10 = 180

Subtracting 10 from both sides:

10x = 170

Dividing both sides by 10:

x = 17°

Now find the measure of angle W by substituting x = 17 into the expression for m∠W:

m∠W = (x + 12) = (17 + 12) = 29°
