Average waiting time for FCFS: 8.75

Average waiting time for SJF: 4.75

To solve this scheduling problem using FCFS (First-Come, First-Served) and SJF (Shortest Job First) algorithms, let's go step by step:

Schedule order for FCFS:

The FCFS algorithm schedules processes based on their arrival time. So, the schedule order for FCFS is as follows:

Pl -> P2 -> P3 -> P4

Average waiting time for FCFS:

To compute the average waiting time for FCFS, we need to calculate the waiting time for each process and then take the average.

Process | Arrival Time | Running Time | Waiting Time

Pl | 0 | 3 | 0

P2 | 3 | 10 | 3

P3 | 4 | 6 | 13

P4 | 5 | 1 | 19

Average waiting time = (0 + 3 + 13 + 19) / 4 = 8.75

Therefore, the average waiting time for FCFS is 8.75.

Schedule order for SJF:

The SJF algorithm schedules processes based on their running time. The process with the shortest running time gets executed first. If multiple processes have the same running time, the process with the earliest arrival time is selected first. The schedule order for SJF is as follows:

Pl -> P4 -> P3 -> P2

Average waiting time for SJF:

To compute the average waiting time for SJF, we need to calculate the waiting time for each process and then take the average.

Process | Arrival Time | Running Time | Waiting Time

Pl | 0 | 3 | 0

P4 | 5 | 1 | 3

P3 | 4 | 6 | 6

P2 | 3 | 10 | 10

Average waiting time = (0 + 3 + 6 + 10) / 4 = 4.75

Therefore, the average waiting time for SJF is 4.75.

Answer:

Step-by-step explanation:

To find the normal plane and osculating plane, we first need to find the required derivatives.

x = 5t, y = t^2, z = t^3

dx/dt = 5, dy/dt = 2t, dz/dt = 3t^2

So, the velocity vector v and acceleration vector a are:

v = <5, 2t, 3t^2>

a = <0, 2, 6t>

Now, let's evaluate them at t = 1 since the point (5, 1, 1) is given.

v(1) = <5, 2, 3>

a(1) = <0, 2, 6>

The normal vector N is the unit vector in the direction of a:

N = a/|a| = <0, 1/√10, 3/√10>

Using the point-normal form of the equation for a plane:

normal plane equation = 0(x-5) + 1/√10(y-1) + 3/√10(z-1) = 0

Simplifying this equation we get:

5x + 2y + 3z = 30

The osculating plane can be found using the formula:

osculating plane equation = r(t) · [(r(t) x r''(t))] = 0

where r(t) is the position vector, and x is the cross product.

At t = 1, the position vector r(1) is <5, 1, 1>, v(1) is <5, 2, 3>, and a(1) is <0, 2, 6>.

r(1) x v(1) = <-1, 22, -5>

r(1) x a(1) = <12, -6, -10>

v(1) x a(1) = <-12, 0, 10>

Substituting these values into the formula, we get:

osculating plane equation = (x-5, y-1, z-1) · <12, -6, -10> = 0

Simplifying this equation we get:

3x - 15y + 5z = 5

Therefore, the equations for the normal plane and osculating plane at (5, 1, 1) are:

(a) 5x + 2y + 3z = 30

(b) 3x - 15y + 5z = 5

Answer: 1.28

Step-by-step explanation:

1. P(Z > 0.99) = 1 -Ф (0.99) = 1-0.8389 = 0.1611

2.P(Z <-0.99) = Ф(-0.99) = 0.161 (known that from [a] by symmetry)

3.P(Z <0.99) = Ф(0.99) = 0.8389

4. P(Z >0.99) = P(Z <-0.99) + P(Z > 0.99) = 2(0.1611) = 0.3222

The value z = 10.0 is out because it is too large. On comparing with the largest value, z = 3.99,

we get

5. P(Z < 10.0) > P(Z <3.99) = 1.0

6.P(Z > 10.0)<P(Z > 3.99) =10.0

7. On solving the equation

Ф(Z) = 0.9

for Z.

In Table A4, find the value of z corresponding to the probability 0.9. The  nearest value is Ф(1.28) = 0.8997. Therefore, z ≈ 1.28

The point (4,80) represents the distance covered by a bicyclist who rides 80 miles in 4 hours, where 4 represents the number of hours and 80 represents the distance covered in miles.

In the given scenario, the constant of proportionality is the rate of speed at which the bicyclist is riding, which is calculated as distance/time or 80/4 = 20 miles per hour. The equation in the form of y = kx for this relationship is y = 20x, where y represents the distance covered in miles and x represents the time taken in hours. The constant of proportionality, k, is equal to 20, which represents the speed at which the bicyclist is riding. Therefore, the equation y = 20x represents the relationship between the distance covered by the bicyclist and the time taken to cover that distance.

The speeds for each of the given distance and times are;

A) 45 miles per hr

B) 22 miles per hr

C) 30 miles per hr

D) 50 miles per hr

E) 65 miles per hr

To convert the given values of distance and time to speed in miles per hour, we will just divide the time by the distance. Speed = distance/time

A) 135 miles in 3 hours. Thus;

Speed = 135/3 miles per hour = 45 miles per hr

B) 22 miles in 1 hour. Thus;

Speed = 22/1 miles per hr = 22 miles per hr

C) 7.5 miles in 1/4 hour. Thus;

Speed = 7.5/(1/4) miles per hour = 30 miles per hr

D) 100/3 in 2/3 hour. Thus;

Speed = (100/3 ÷ 2/3) = 50 mph

The bottom right graph shows the line of best fit for the data.

For a data-set, the definition of a residual is that it is the difference of the actual output value by the predicted output value, that is:

Residual = Observed - Predicted.

Hence the graph of the line of best fit should have the smallest possible residual values, meaning that the points on the scatter plot are the closest possible to the line.

For this problem, we have that the bottom right graph has the smaller residuals, hence it shows the line of best fit for the data.

Answer:

A)  The function has a maximum value of 1

Step-by-step explanation:

Since the parabola opens downward, then its maximum would be 1 and its minimum would be -∞

After the loop terminates, x has the value 128.

If x is an int where x = 0, then x will be 128 after the following loop terminates:

while (x < 100)x *= 2

In the loop given above, the value of x is 0. The loop continues to execute as long as the value of x is less than 100. In the loop, x is multiplied by 2 in each iteration. If we multiply 0 by any value, the result will always be 0.

Therefore, the loop does not execute in the first iteration itself. But after that, the value of x becomes 0 since it has been multiplied by 2 in each iteration.

In this case, it will be multiplied by 2 six times before the value of x becomes greater than or equal to 100.2⁶ = 64So, x = 64 after six iterations.

After the loop terminates, x has the value 128.

The final total including tax is 838.5

The sale tax is 58.5

Step-by-step explanation:

The exact value of the expression cos(-10pi/3) is -1/2.

To find the exact value of cos(-10pi/3), follow these steps:

1. Determine the equivalent positive angle: Since the cosine function has a period of 2pi, we can add multiples of 2pi to the angle until we get a positive angle. In this case, we add 4pi (since 4pi = 12pi/3) to get the equivalent positive angle:
  (-10pi/3) + (12pi/3) = 2pi/3.

2. Find the cosine value of the positive angle: Now, we find the cosine value of the positive angle 2pi/3. Using the unit circle, we can determine that cos(2pi/3) = -1/2.

So, the exact value of the expression cos(-10pi/3) is -1/2.

Answer:

  (c)  AE = x·cos(α)/sin(θ)

  (d)  BD = x·cos(α)cos(α-θ)/cos(θ)

Step-by-step explanation:

In the given diagram, you want expressions for (c) AE and (d) BD in terms of x, α, and θ.

The law of sines can be used in ∆ACE to give the measure of AE.

\(\dfrac{AE}{\sin(C)}=\dfrac{CE}{\sin(\theta)}\\\\\boxed{AE=\dfrac{x\,\cos(\alpha)}{\sin(\theta)}}\qquad\text{where $\sin(C)=\cos(\alpha)$ and $CE=x$}\)

The length BD can be found in terms of AD and θ:

  BD = AD·tan(θ)

The length AD can be found in terms of AE and (α-θ):

  AD = AE·cos(α-θ)

Using the value of AE from part (c), we have ...

  BD = AE·cos(α-θ)·tan(θ) = x·cos(α)cos(α-θ)·tan(θ)/sin(θ)

  BD = x·cos(α)cos(α-θ)/cos(θ) . . . . . . . using tan/sin = 1/cos

The correct answer is C. False because Ø contains no elements so nothing can belong to it.

In the area of mathematical logic known as set theory, we study sets and their characteristics. A set is a grouping or collection of objects. These things are frequently referred to as elements or set members. A set is, for instance, a team of cricket players.

We can say that this set is finite because a cricket team can only have 11 players at a time. A collection of English vowels is another illustration of a finite set. However, many sets, including sets of whole numbers, imaginary numbers, real numbers, and natural numbers, among others, have an unlimited number of members.
