what is the probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour?

Answers

The probability that the request is received by the server within the first 5 minutes (300 seconds) after the hour would depend on the rate at which requests are made to the server, as well as any other factors that may affect the timing of requests.

In order to find this probability, you would need additional information such as the average rate of requests per second or minute, and the distribution of request timing.

If the requests are Poisson distributed with a mean rate of λ requests per second, the probability that a request is received within the first 5 minutes (300 seconds) after the hour is

A system of equations is shown below. y = 3x + 4 y = 7x – 2 What is the solution to the system?

Answers

The solution to the system of equations is x = 3/2 and y = 11/2.

What is the linear equation?

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of a linear equation is y=mx + b

We are given two equations:

y = 3x + 4

y = 7x – 2

We can set the two equations equal to each other and solve for x:

3x + 4 = 7x - 2

Subtracting 3x from both sides:

4 = 4x - 2

Adding 2 to both sides:

6 = 4x

Dividing both sides by 4:

x = 3/2

Now we can substitute this value of x back into either of the original equations to find the corresponding value of y. Using the first equation:

y = 3(3/2) + 4 = 9/2 + 4 = 11/2

Therefore, the solution to the system of equations is x = 3/2 and y = 11/2.

antti entered a 10 kilometer race. his goal is to finish in one hour. he starts off sprinting, and completes the first 2 kilometers of the race at an average speed of 12 kilometers per hour. to achieve his goal of a one-hour finish time, what average speed must antti maintain for the last 8 kilometers of the race?

Answers

So, Antti must maintain an average speed of 8 kilometers per hour for the last 8 kilometers of the race in order to finish in one hour.

To finish the 10 kilometer race in one hour, Antti must maintain an average speed of 10 kilometers per hour for the entire race. Since he has already completed 2 kilometers at an average speed of 12 kilometers per hour, he must make up for that extra speed by running the last 8 kilometers at a slower pace.

To find out what average speed he must maintain for the last 8 kilometers to finish in one hour, we can use the formula:

(distance) / (time) = (speed)

So, 8 / 1 = 8 kilometers per hour

The area of a rectangle is represented by 32X exponent three it’s a length of a rectangle is 4X then the width is 

Answers

Answer:We know that the area of a rectangle is represented by the product of its length and width, so the equation for the area of the rectangle is:

A = l * w

We also know that the area of the rectangle is given as 32X^3 and the length of the rectangle is 4X. Therefore, we can substitute these values into the equation:

32X^3 = (4X) * w

To find the width of the rectangle, we can divide both sides of the equation by 4X:

w = 32X^3 / 4X

Simplifying the equation, we can get the value of w:

w = 8X^2

So the width of the rectangle is 8X^2

Step-by-step explanation:

Let's solve your system by substitution.

y=3x+13; y=7x+17

Step: Solve y = 3x + 13 for y:

y=3x+13

Step: Substitute 3x + 13 for y in y = 7x + 17 :

y=7x+17

3x+13= 7x+17

3x+13+-7x=7x+17+-7x (Add -7x to both sides)

-4x+13=17

-4x+13+-13=17+-13 (Add -13 to both sides)

-4x=4

-4x/-4 = 4/-4 (Divide both sides by -4)

x=-1

Step: Substitute -1 for x in y=3x+13:

y=3x+13

y=(3)(-1)+13

y=10(simplify both sides of the equation)

Answer:

x= -1 and y= 10

In an experiment with probability function f(x) is binomially distributed with probability p that an attribute occurs at a single trial. If in four trials of the experiment, the attribute occurs four times with probability 16/81, find the value of p

Answers

Answer:

Step-by-step explanation:

A binomial probability function has two parameters: n, the number of trials and p, the probability of success (or occurrence of the attribute) in a single trial.

In this case, we are given that the attribute occurs four times in four trials, with probability 16/81. Using this information, we can use the binomial probability formula to find the value of p:

P(k) = (n choose k) * p^k * (1-p)^(n-k)

Where k is the number of successes in n trials, and (n choose k) is the binomial coefficient, which is the number of ways to choose k items from n items without replacement.

In this case,

k = 4 (the attribute occurs four times)

n = 4 (there are four trials)

P(k) = 16/81

We can use this equation to find the value of p:

(4 choose 4) * p^4 * (1-p)^(4-4) = 16/81

1 * p^4 * (1-p)^0 = 16/81

p^4 = 16/81

p = √(16/81)

p = √(4/81)

p = √(1/81)

p = 1/9

The value of p is 1/9

This means that in a single trial of the experiment, the probability of the attribute occurring is 1/9 or about 0.111

does this approximate a normal distribution? does this confirm the first part of the central limit theorem?

Answers

No, this does not approximate a normal distribution.

This does not confirm the first part of the Central Limit Theorem, which states that the sum of a large number of independent random variables will approximate a normal distribution. To calculate the probability of a normal distribution, we need to calculate the mean and standard deviation of the sample. We can then use this information to calculate the z-score of a given value in the sample. The z-score will tell us how many standard deviations away from the mean a certain value is. If the z-score follows a normal distribution then the sample approximates a normal distribution. However, if the z-score does not follow a normal distribution then the sample does not approximate a normal distribution.

0.80 is the expected value of wei's ticket. This can be solved by using the concept of probability.

What is probability?

The word "probability" derives from the Latin word "probitatem," which means "credibility, likelihood," from the noun probabilis in the 14th century (see probable). The phrase was first used in a mathematical meaning in 1718.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

As, we know

E(x) = x₁. p(x₁) + x₂ . p(x₂) + ....... + x(n). p(x(n))

From the table it is shown that,

E(x) = (68% × 0) + (24% × 0) + (6% × 5) + (2% × 25)

or, E(x) = 0.80
