The pressure p and volume v of a given mass of gas are connected by the relation
k=(p+a\v^2)(v-b)
where a, b, and k are constants.
Using the composite trapezoidal method, write a MatLab script to approximate the work done by the gas in expanding from an initial volume to a final volume. Express p in terms of v.
Where W = Integral (Pdv)

Let V be a vector space of dimension 1 over a field k and choose a fixed nonzero element voe V, which is therefore a basis. Let W be any vector space over k and let woe W be an arbitrary vector. Show that there is a unique linear transformation T: V → W such that T(v)= wo. [Hint: What must T(Avo) be?)

A stellar object that is at a great distance emits a stream of
matter at velocity v towards an observer obliquely, forming an
angle θ with the observation line. For the observer the jet appears
to have been emitted laterally at speed V.
Show that for certain angles the speed measured by the observer may
exceed the speed of light.
V = sin θ (1 / v - cos θ) −1

River Plant. Selected data for an average month for the two
products follow.

Production at the plant is automated and any labor cost is included
in overhead. Data on manufacturing overhead at the plant

a. Compute the unit costs for the two products
V-1 and V-2 using the current costing system at Upriver (using
machine hours as the allocation basis). (Do not round
intermediate calculations. Round your answers to 2 decimal
places.)
b. Compute the unit costs for the two products V-1

Consider a binary channel transmitting bits independently. Each bit is demodulated with a 0 corresponding to 0 volts and a 1 corresponding to 5 volts. Thus, the received random variable v is normally distributed with variance σ2 = 1 and mean μ = 0 or μ = 5. The demodulated voltage v is compared to a threshold τ to decide whether a bit is a 0 or 1, i.e., decide that a 1 was sent if v > τ and that a 0 was sent if v < τ. Bits are equally probable so that P ( μ = 0 ) = P ( μ = 5 ) = 1 / 2. Note that an error occurs either if a 0 was sent so that μ = 0 but v > τ and a 1 is decided or if a 1 was sent so that μ = 5 but v < τ and a 0 is decided. What are the conditional probabilities P ( v > τ | μ = 0 ) and P ( v < τ | μ = 5 )? What is the resulting probability of error? What value should one choose for τ to minimize the probability of error? If 1250 bytes (8 bits each) are sent, what is the expected number of errors?

In a study conducted by some Statistics students, 69 people were randomly assigned to listen to rap music, music by Mozart, or no music while attempting to memorize objects pictured on a page. They were then asked to list all the objects they could remember. The summary statistics for each group are shown in the table. Complete parts a and b.
a.Does it appear that it is better to study while listening to Mozart than to rap music? Test an appropriate hypothesis and state your conclusion. Let group M correspond to Mozart listeners and group R correspond to rap listeners. Write the null and alternative hypotheses. b. Find p and t values c. State the conclusion d.Now compare the group that listened to Mozart with the group that listened to no music. Create a 90 % a confidence interval for the mean difference in memory score between students who listen to Mozart and those who listen to no music at all. Interpret your interval. |

The students answered questions about alcohol use and hangovers, including a count of how many out of a list of 13 possible hangover symptoms they had experienced in the past year. For the 470 men, the mean number of symptoms was 5.4; for the 755 women, it was 5.1. The standard deviation was 3.7 for each of the two samples.
(a) Define the parameter of interest using appropriate notation. The parameter of interest is Correct: Your answer is correct. in mean number of hangover symptoms, out of the 13 listed, experienced by the populations of male and female college students similar to those in the study.
(b) Find the standard error of the difference in means. (Round the answer to four decimal places.) s.e.(x1 - x1) =
(c) Find an approximate 95% confidence interval for the difference in population means. (Round all answers to two decimal places.) to symptoms
(d) On the basis of your interval in part (c), do you think that there is a difference in the population mean number of hangover symptoms experienced by college men and women? There Correct: Your answer is correct. a difference in the mean number of symptoms in the population.

Given: You are given a Python Class template. In this class
there is a
class variable vector, is a list of N non-negative integers and
are
stored (in positions 0, 1, 2, ... (N-1)), where at least one
integer
is 0.
Task: Write a recursive function "findAllPaths" to find all
possible
path through V starting at position 0, and ending at
the location of 0, in accordance with the Rule below.
If no such path exists, "paths" should be an empty list. You
also
have to write functions called "getShortest" and "getLongest"
which
return respectively the shortest and longest paths as lists.
Rule: From position i, the next position in the path must be either
i+x,
or i-x, where x is the non-negative integer stored in position
i.
There is no path possible from position i to position i+x if
either of these 2 conditions hold:
position i+x is beyond the end of V.
position i+x is already on the path.
There is no path possible from position i to position i-x if
either of these 2 conditions hold:
position i-x is beyond the start of V.
position i-x is already on the path.
Example:
Suppose V contained the following:
Position: 0 1 2 3 4 5 6 7 8 9 10 11
Integer: 2 8 3 2 7 2 2 3 2 1 3 0
Then one path is:
0 2 5 7 4 11
Recursive Algorithm
-------------------
Your solution MUST use a recursive function to identify the
paths.
You must implement the recursive function, as follows:
def findAllPaths(self, position, solution):
"findAllPaths" takes the initial part of a solution Path,
and
a potential next solution position in the Vector. It explores
paths with the given position appended to the given solution
path so far.
The class variable paths is a list of lists and the function
Example Run:
------------
Example vector: [2, 8, 3, 2, 7, 2, 2, 3, 2, 1, 3, 0]
Valid paths:
0 2 5 7 4 11
0 2 5 3 1 9 10 7 4 11
0 2 5 3 1 9 8 10 7 4 11
0 2 5 3 1 9 8 6 4 11
No Solution example:
3 1 1 1 3 4 2 5 3 0
The following template is given:
def getName():
# Use the name displayed on D2L (easier for us to find)
return "Haque, Mohammad"
class Pathfinder():
def __init__(self, vector):
# Initialize the Pathfinder object
self.vector = vector
self.paths = []
self.findAllPaths(0,[])
def findAllPaths(self, position, solution):
# Recursively explore the possible paths and store valid
paths
# This method will not be tested, so you can modify the parameters
as needed
print("hi")
pass
def getLongest(self):
# Return the longest of all paths found or [] if no paths
exist
# If multiple paths with the longest length exist, return one of
them
pass
def getShortest(self):
# Return the shortest of all paths found or [] if no paths
exist
# If multiple paths with the shortest length exist, return one of
them
pass
Any help will very much appreciated
