Answer 1

The given improper integral converges to the finite value of 0.0833... by using u-substitution and evaluating the limit as the upper limit approaches infinity.

We can determine whether the given improper integral converges or diverges by evaluating the limit of the integral as the upper limit approaches infinity

∫(1 to ∞) 1/(3x+1)^2 dx = lim t→∞ ∫(1 to t) 1/(3x+1)^2 dx

To evaluate the integral, we can use u-substitution, letting u = 3x + 1 and du = 3dx

∫(1 to t) 1/(3x+1)^2 dx = (1/3) ∫(4 to 3t+1) u^(-2) du

= (1/3) [-u^(-1)] from 4 to 3t+1

= (1/3) [(3t+1)^(-1) - 4^(-1)]

Taking the limit as t approaches infinity

lim t→∞ (1/3) [(3t+1)^(-1) - 4^(-1)]

= (1/3) * 0.25 = 0.0833...

Since this limit exists and is finite, the improper integral converges to 0.0833...

customers send emails to a help desk of an online retailer every 2 minutes, on average, and the standard deviation of the inter-arrival time is also 2 minutes. the online retailer has three employees answering emails. it takes 4 minutes to write a response email, on average. the standard deviation of the service times is 2 minutes. this is a g/g/k queue. what is the arrival rate? what is the service rate?

Answers

The arrival rate is found to be 30 emails per hour and the service rate is calculated to be 45 emails per hour.

It has been mentioned in the question that in every 2 minutes, customers send emails to a help desk of an online retailer, on an average, and the standard deviation of the inter-arrival time is also given to be 2 minutes. The online retailer has three employees for answering those emails.

It takes almost 4 minutes to write a response email to the customer, on average. The standard deviation (SD) of the service times is 2 minutes. This is a g/g/k type queue.

Therefore the arrival rate per hour is given by the following relation:

Arrival rate in 1 hr = No. of minutes in an hr / inter arrival time of email taken in minutes

Given here,

No. of minutes in an hour = 60 minutes

Inter arrival time of the email taken in minutes = 2 minutes

Arrival rate in 1 hr = 60 / 2

                                = 30 emails / hr

Hence the arrival rate is 30 emails per hour.

Now for finding out the service rate we have the following formula:

Service rate = No. of minutes in an hr x No. of employes answering/ average time that is required to write response email

Given here,

No. of minutes in an hr = 60 minutes

No. of employes answering = 3

Average time that for writing response email = 2 minutes

∴ Service rate = 60 * 3 / 4

                       = 45 emails / hr

Hence the service rate is 45 emails per hour.

Write an equation to find the total hours of video games played by William in any number of days.

Answers

The equation is H=d*h total hours of video games played by William.

We'll abbreviate William's daily video game playing as "d." The total amount of hours he plays can be expressed mathematically as follows:

Hours = H

H = d * h

where "h" stands for the daily number of hours he plays.

A period of time equal to \(\frac{1}{24}\) (a twenty-fourth) of a day. 1 Day = 24 Hours. 1 Hour = 60 minutes

Therefore, the equation to get the total number of hours William spent playing video games in any number of days is:

H = d * h

Where d is the number of days and h is the daily playing time.

Therefore, the equation is d*h.

consider selecting two elements, a and b, from the set a = {a, b, c, d, e}. list all possible subsets of a using both elements. (remember to use roster notation. ie. {a, b, c, d, e})

Answers

Thus, the possible subsets of the set a = {a, b, c, d, e} using both elements a and b are: {a, b}, {a, b, c}, and {a, b, d}.

To find all possible subsets of the set a = {a, b, c, d, e} using both elements a and b, we need to consider all the possible combinations of these two elements with the remaining elements in the set.

There are three possible subsets that we can create using both elements a and b:

1. {a, b} - This is the subset that contains only the elements a and b.
2. {a, b, c} - This subset contains the elements a and b, along with the third element c.
3. {a, b, d} - This subset contains the elements a and b, along with the fourth element d.

Note that we cannot create any more subsets using both elements a and b because we have already considered all the possible combinations with the remaining elements in the set.

In summary, the possible subsets of the set a = {a, b, c, d, e} using both elements a and b are: {a, b}, {a, b, c}, and {a, b, d}.

Answers

The expectation value of the position squared when the particle in the box is in its third excited state is equal to \(\frac{9l^2}{8}\), where l is the length of the box. This is equal to nine-eighths of the length of the box squared.

The expectation value of the position squared when the particle in the box is in its third excited state can be calculated using the formula\(\langle x^2 \rangle = \frac{l^2}{8} \left( 2n^2 + 6n + 3 \right)\),

where n is the quantum number of the state and l is the length of the box. Here, n is 3, so the expectation value is equal to

\(\frac{l^2}{8} \left( 2 \times 3^2 + 6 \times 3 + 3 \right) = \frac{9l^2}{8}\).

This can be written as nine-eighths of the length of the box squared.

Joy makes 6.5 litres soup correct to the nearest 0.5 litres. She serves the soup in 280ml portions correct to the nearest 10ml. 22 people order this soup. Does joy definitely has enough soup to serve the 22 people.

Answer:

Yes, Joy definitely does has enough soup

Step-by-step explanation:

From the question, we know,

Joy make 6.5 litres of soup

Serves it in 280ml portions

Step 1

We convert the portions to liters

1 ml = 0.001 litre

280 ml

= 280ml × 0.001 litre/1 ml

= 0.28litre

Step 2

We divide 6.5 liters by 0.28 to find out how many people can be served

= 6.5 ÷ 0.28

= 23.2142857143 people

We can see that 6.5 liters soup can serve 23 people approximately.

Therefore, Yes, Joy definitely does has enough soup to serve 22 people

A family pass to the amusement park costs $54. Using Distributive Property, write an expression that can be used to find the cost in dollars of 8 family passes. (I'm actu

Answers

The cost of 8 family passes to the amusement park is $432 when a family pass to the amusement park costs $54.

To find the cost of 8 family passes to the amusement park, we can use the Distributive Property of multiplication over addition. The Distributive Property states that a(b + c) = ab + ac, where a, b, and c are numbers. In this case, we can use the Distributive Property to write:

8 x $54 = (5 x $54) + (3 x $54)

We can see that we have broken 8 down into two smaller numbers that we can multiply by $54 individually, and then add together. The first term, 5 x $54, represents the cost of 5 family passes, while the second term, 3 x $54, represents the cost of 3 family passes. Adding these two values together, we get:

(5 x $54) + (3 x $54) = $270 + $162 = $432

Therefore, the cost of 8 family passes to the amusement park is $432.

Write the sentence as an inequality. Three times a number r plus 8 is fewer than −12

Answers

Answer: \(3r+8<-12\).

Step-by-step explanation:

It is given that three times a number r plus 8 is fewer than −12.

We need to write the sentence as an inequality.

Three times a number r = 3r

Times a number r plus 8 = 3r+8

Fewer than = less than = <

So, the inequality for the sentence "three times a number r plus 8 is fewer than −12" is

\(3r+8<-12\)

Therefore, the required inequality is \(3r+8<-12\).

The inequality that describes the sentence is:

\(3r + 8 < -12\)

--------------------------------

3 times 1 is \(3 \times 1 = 3\), 3 times 2 is \(3 \times 2 = 6\), and so on, thus 3 times a number r is \(3 \times r = 3r\).The plus word means that we have an addition operation, plus 8, thus \(3r + 8\)Fewer than -12 means that the less than -12 completes the inequality, thus:

\(3r + 8 < -12\)

Which is the inequality that describes this situation.
