6.2.2 )X is t he Gaussian (0, 1) random variable.
Find the CDF of Y = IXI and its
expected value E[Y).
7.1.2) Xis the discrete uniform (0, 5) random
variable. What is E[ XIX >= E[X]]?

Answers

Answer 1

The Gaussian (0, 1) random variable is also known as the standard normal distribution, where the mean (µ) is 0 and the standard deviation (σ) is 1. The notation E[X] represents the expected value of X, which is the mean of the probability distribution of X.

Now, let's break down the expression E[ XIX >= E[X]]. The symbol IX >= E[X] means that we are considering only those values of X that are greater than or equal to the expected value of X. In other words, we are looking at the right tail of the distribution.

To calculate E[ XIX >= E[X]], we need to find the expected value of X, given that X is greater than or equal to the expected value of X. This is also known as the conditional expected value.

One way to approach this problem is to use the formula for conditional probability:

P(A|B) = P(A and B) / P(B)

In our case, A represents the event XIX, and B represents the event X >= E[X].

We know that X is a standard normal distribution, which means that its probability density function (PDF) is given by:

f(x) = (1 / sqrt(2π)) * e^(-x^2/2)

Using this PDF, we can calculate the probabilities of the events A and B:

P(A) = ∫x=0^∞ f(x) * x dx = 1/2

P(B) = ∫x=0^∞ f(x) dx = 1/2

P(A and B) = ∫x=0^∞ f(x) * x dx = 1/2

Therefore, the conditional probability P(A|B) = P(A and B) / P(B) = 1.

This means that the expected value of X, given that X is greater than or equal to the expected value of X, is equal to 1.

Therefore, E[ XIX >= E[X]] = 1 * P(X >= E[X]) = 1/2, since the probability of X being greater than or equal to its mean is 1/2 for a standard normal distribution.

In summary, E[ XIX >= E[X]] = 1/2 for a standard normal distribution.

Answer 2

Since X is a standard Gaussian, we know that E[|X|] = √(2/π). Therefore,

E[Y] = 2 √(2/π) ≈ 1.5958.

6.2.2)

Let's start by finding the CDF of Y = IXI.

For any given value of y, we have two cases:

1. If y < 0, then P(Y <= y) = 0 because Y can only take non-negative values.

2. If y >= 0, then P(Y <= y) = P(-y <= X <= y) = F_X(y) - F_X(-y), where F_X is the CDF of X.

Since X is a standard Gaussian, we know that F_X(x) = Φ(x), where Φ is the standard Gaussian CDF. Thus,

P(Y <= y) = Φ(y) - Φ(-y) for y >= 0.

To find the expected value of Y, we use the definition of the expected value:

E[Y] = ∫(-∞ to ∞) y f_Y(y) dy, where f_Y is the PDF of Y.

To find f_Y, we can differentiate the CDF we just found:

f_Y(y) = d/dy [Φ(y) - Φ(-y)] = φ(y) + φ(-y), where φ is the standard Gaussian PDF.

Thus,

E[Y] = ∫(0 to ∞) y (φ(y) + φ(-y)) dy

= ∫(0 to ∞) y φ(y) dy + ∫(0 to ∞) y φ(-y) dy

= 2 ∫(0 to ∞) y φ(y) dy (by symmetry)

= 2 E[|X|]

Since X is a standard Gaussian, we know that E[|X|] = √(2/π). Therefore,

E[Y] = 2 √(2/π) ≈ 1.5958.

7.1.2)

We start by finding E[X], which is the expected value of a discrete uniform random variable on the interval [0,5]. Since the distribution is uniform, we have E[X] = (a+b)/2 = (0+5)/2 = 2.5.

Next, we need to find E[ XIX >= E[X]]. This is the expected value of X given that X is greater than or equal to its expected value. Using the definition of conditional expectation, we have:

E[ XIX >= E[X]] = ∑(i=0 to 5) xi P(X = xi | X >= 2.5)

Since X is discrete uniform, we know that P(X = xi) = 1/6 for all i from 0 to 5. To find P(X = xi | X >= 2.5), we note that X >= 2.5 if and only if X takes on the values 3, 4, or 5. Thus,

P(X = xi | X >= 2.5) =

{ 1/3 if xi = 3, 4, or 5

{ 0 otherwise

Substituting these values into the above expression, we get:

E[ XIX >= E[X]] = (3/6)(3) + (1/6)(4) + (1/6)(5) = 17/6 ≈ 2.8333.

Answers

The maximum height that the water can rise above the jet is: 35 meters.

Maximum height that the water can rise above the jet

Given:

P = 350 kPa = 350000 Pa

We would use pressure(p)  formula to determine the maximum height that the water can rises above the jet by solving for h (height).

Answers

The maximum load that may be applied to a specimen with a cross-sectional area of 130 mm² is; 35535 N

How to find Elastic Modulus?

We are told that for an alloy, the yield stress is 345-MPa and the elastic modulus (E) is 103-GPa.

Now, we want to find the maximum load that may be applied to a specimen with a cross-sectional area of 130-mm² without plastic deformation. Thus;

We are given the parameters;

Yield Stress; σ = 345 Mpa = 345 * 10⁶ Pa

Elastic Modulus; E = 103 GPa = 103 * 10⁹ Pa

Cross sectional Area; A = 130 mm² = 103 * 10⁻⁶ m²

Formula for stress without Plastic deformation is;

σ = F_max/Area

where;

σ is stress

F_max is maximum force

Area is Area

Thus making maximum force the subject of the formula gives;

F_max = σ * A

Plugging in the relevant values for stress and area gives us;

F_max = 345 * 10⁶ * 103 * 10⁻⁶

F_max = 35535 N

Determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt.% at a position of 4 mm into an iron-carbon alloy that initially contains 0.10 wt.% C. The surface concentration is to be maintained at 0.90 wt.% C, and the treatment is to be conducted at C. Use the diffusion data for -Fe in Table 5.2

Answers

Answer:

the carburizing time necessary to achieve a carbon concentration is 31.657 hours

Explanation:

Given the data in the question;

To determine the carburizing time necessary to achieve the given carbon concentration, we will be using the following equation:

(Cs - Cx) / (Cs - C0) = ERF( x / 2√Dt)

where Cs is Concentration of carbon at surface = 0.90

Cx is Concentration of carbon at distance x = 0.30 ; x in this case is 4 mm = ( 0.004 m )

C0 is Initial concentration of carbon = 0.10

ERF() = Error function at the given value

D = Diffusion of Carbon into steel

t = Time necessary to achieve given carbon concentration ,

so

(Cs - Cx) / (Cs - C0) = (0.9 - 0.3) / (0.9 - 0.1)

= 0.6 / 0.8

= 0.75

now, ERF(z) = 0.75; using ERF table, we can say;

Z ~ 0.81; which means ( x / 2√Dt) = 0.81

Now, Using the table of diffusion data

D = 5.35 × 10⁻¹¹ m²/sec at (1100°C) or 1373 K

now we calculate the carbonizing time by using the following equation;

z = (x/2√Dt)

t is carbonizing time

so we we substitute in our values

0.81 = ( 0.004 / 2 × √5.35 × 10⁻¹¹ × √t)

0.81 = 0.004 / 1.4628 × 10⁻⁵ × √t

0.81 × 1.4628 × 10⁻⁵ × √t = 0.004

1.184868 × 10⁻⁵ × √t = 0.004  

√t = 0.004 / 1.184868 × 10⁻⁵

√t = 337.5903

t = ( 337.5903)²  

t = 113967.21 seconds

we convert to hours

t = 113967.21 / 3600

t = 31.657 hours

Therefore, the carburizing time necessary to achieve a carbon concentration is 31.657 hours

In physics, we define angular deviation as the angle resulting from the deflection of light when reflected from a prism. A prism has the ability to separate white light into several other colors, which are reflected by the object.

The comfort condition formula is given by: [tex]L=2(\frac{NV^{3} }{C} )^{\frac{1}{2} }[/tex]

Where, L is the length of the vertical curve, N is the grade, V is the safe speed operation and assuming the standart value for C (0,6 m/s3) it is possible to calculate:

[tex]C = 0,6 m/s^{3} = 1,968 ft/s^{3}\\ N= N1 - N2 = 7,5-0 = 7,5% = 0,075[/tex]

Changing the values in the formula:

[tex]L=2(\frac{NV^{3} }{C}){\frac{1}{2} } \\300 = 2(\frac{0,075.V^{3} }{1,968})^{\frac{1}{2} } \\V = 83,89 ft/s[/tex]

So, the safe operating speed on the highway is 83,89 ft/s.
