On a strange railway line, there is just one infinitely long track, so overtaking is impossible. Any time a train catches up to the one in front of it, they link up to form a single train moving at the speed of the slower train. At first, there are three equally spaced trains, each moving at a different speed. You watch, and eventually (after all the linking that will happen has happened), you count the trains. You wonder what would have happened if the trains had started in a different order (but each of the original three trains had kept its same starting speed). On average (averaging over all possible orderings), how many trains will there be after a long time has elapsed? what if at the start there are 4 trains (all moving at different speeds)? or 5? or n?
Answers
On average The number of trains after a long time is = 2 trains
Given data :
Number of trains = 3
Let's assume :
speed of Train 1 = V₁
speed of Train 2 = V₂
speed of Train 3 = V₃
Determine the number of trains after a long time has elapsed Before linkage = 3 trains When ( Train 1 and Train 2 links ) = 2 trains When ( Train 1 , Train 2 and Train 3 links ) = 1 train When ( Train 2 and Train 3 links ) = 2 trainsTherefore the average number of trains after a long time will be
( 3 + 2 + 1 + 2 ) / 4
= 8 / 4
= 2 trains
Hence we can conclude that On average The number of trains after a long time is = 2 trains

for the pipe system below, we assume the cross-section at is subject to the resultant forces and . the pipe gauge pressure is given by . use the dimensions , and . the circular cross-section has outer diameter and inner diameter .
Answers
The given problem involves a pipe system with a circular cross-section that is subject to resultant forces and has a gauge pressure given by a specific equation. The dimensions of the pipe, including the outer and inner diameter, are also provided.
To solve this problem, we need to first understand the given information. The circular cross-section of the pipe has an outer diameter (d) and an inner diameter (d_i). We assume that the cross-section at a particular point is subject to resultant forces (R) and (S). The pipe gauge pressure (P) is given by the equation P = (R + S) / (2 * t), where t is the thickness of the pipe wall.
Using the provided dimensions, we can calculate the value of t by subtracting the inner diameter from the outer diameter and dividing by 2: t = (d - d_i) / 2. We can then substitute this value into the equation for P to calculate the gauge pressure.
In conclusion, the pipe system described in the problem can be analyzed using the given dimensions and the equation for gauge pressure. By understanding the properties of the circular cross-section, we can calculate the thickness of the pipe wall and use it to determine the gauge pressure based on the resultant forces.

Brianna models a can of ground coffee as a right cylinder. She measures its height as 6 1/4 in its radius as in 3/4in. Find the volume of the can in cubic inches. Round your answer to the nearest tenth if necessary.
Answers
To find the volume of the can, we can use the formula for the volume of a cylinder:
Volume = π * r^2 * h
Given:
Height of the can = 6 1/4 inches (or 6.25 inches)
The radius of the can = 3/4 inches (or 0.75 inches)
Plugging these values into the formula, we get:
Volume = π * (0.75)^2 * 6.25
Calculating this, we find:
Volume ≈ 3.14159 * 0.5625 * 6.25
Volume ≈ 10.973
Rounding to the nearest tenth, the volume of the can is approximately 11.0 cubic inches.

using the difference in interest between the credit card and savings account from problem 3, how much total interest could you save by putting all $500 instead of just $250 toward the credit card at the beginning of the month
Answers
The total interest that you could save by putting all $500 instead of just $250 toward the credit card at the beginning of the month is: $2.19.
How to find the simple Interest?Simple interest is defined as a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest on $250 for a month = 250*4* (1/12) * 1/100
Simple interest on $250 for a a month = $0.83
The difference in the amount of interest accrued between the credit card and savings account = $19.24 - $0.83 = $18.41
If $500 was paid instead of $250, then it means that the balance on which interest would have been levied = $1,842.66-$500
= $1342.66
The Interest levied on $1342.66 = 1342.66 * (14.5/100) * 1/12
= $16.22
Thus, interest saved = $18.41 - $16.22
= $2.19
Therefore, The difference in the amount of interest accrued between the credit card and savings account is $18.41.

The lifetime of a particular type of car tire is normally distributed. The mean lifetime is 50,000 miles, with a standard deviation of 5,000 miles. Of a random sample of 15,000 tires, how many of the tires are expected to last for between 45,000 and 55,000 miles?
Answers
Answer:
10,240 tires
Explanation:
To calculate the percentage of tires that are expected to last for between 45,000 and 55,000 miles, we need to find P(45000 < X < 55000).
Calculator input for "normal cumulative distribution function (cdf)":
Lower bound: x = 45000Upper bound: x = 55000Mean, μ = 50000Standard deviation, σ = 5000⇒ P = 0.682689492...
⇒ P = 68.27%
Therefore, approximately 68.27% (2 d.p.) of tires are expected to last for between 45,000 and 55,000 miles.
To find the number of tires that are expected to last between 45,000 and 55,000 miles from a random sample of 15,000, multiply the found percentage by the number in the sample:
⇒ 0.682689492... × 15000 = 10240.3428...
Therefore, of a random sample of 15,000 tires, 10,240 tires are expected to last for between 45,000 and 55,000 miles.

Let's say that this computer is on my desk, which is caused by gravity. Gravity is causing my computer to stay on my desk right now. This also influences our solar systems, however, gravity is much different there, because gravity has to ensure that the planets stay put in the solar system. For instance, the gravity on the moon influences earth because the gravitational pull causes ocean tides. Gravity also creates stars using material in the solar system from which stars are made.

The least possible value of (6/5)p+2 is C) 16.
How to estimate the least possible value of (6/5)p+2?To compute the least possible value of (6/5)p+2, we first solve the inequality (3/5)p - 2 ≥ 5:
(3/5)p - 2 ≥ 5
(3/5)p ≥ 7
p ≥ 35/3
Next, we find the least possible value of (6/5)p+2:
Putting p = 35/3 into the expression, we have:
(6/5)(35/3) + 2 = 16
Let us solve (6/5)(35/3), first.
So, (6/5)(35/3) = (6 * 35) / (5 * 3) = 210 / 15 = 14.
Then, we add 2:
14 + 2 = 16.
Thus, the least possible value of (6/5)p+2 is 16.

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place
Answers
Answer:
To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:
Standard Error = Standard Deviation / √(Sample Size)
= 92 / √(90)
≈ 9.685
Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.
Now we can calculate the confidence interval:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
= 1700 ± (1.96 * 9.685)
Lower Limit = 1700 - (1.96 * 9.685)
≈ 1679.69
Upper Limit = 1700 + (1.96 * 9.685)
≈ 1720.31
Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.
