Answer:

I think it's C.

Explanation:

I could be wrong, but this is my understanding. M3 equals the sum of all money in the economy. To get M3, you add M2 and M1. So, this would be the correct way to calculate the money supply with M2.

Dean Smith is dissatisfied with the time it takes to get a new faculty ID made and believes more servers will speed up service and reduce costs thanks to shorter lines. Prof. Karen is tasked to study the situation. Prof. Karen observes an average of 20 customers/hr arriving and each technician (service window) serves 5 customer/hr, on average. Assume an M/M/s queue system. Prof. Karen calculates the operational cost of each server as $20/hr, and assumes a cost of waiting in the SYSTEM as $25/hr per customer. What is the optimal number of service windows to minimize total cost

Answers

The answer is :

X = 4

Explanation:

The optimal number of service windows to minimize total cost will be 5 service windows.

How to calculate the optimal value?

The optimal number of service windows to minimize total cost will be calculated thus:

Cost = 20x + 25(20 - 5x)

Cost = 20x + 500 - 125x

Cost = 500 - 105x

For the minimum cost,

500 - 105x = 0

105x = 500

x = 500/105

x = 4.76 = 5

Therefore, the optimal number of service windows to minimize total cost will be 5 service windows.

Building a String Library

Sometimes when programming you need to introduce a new data type and develop a library of functions for manipulating instances of that data type. Often this is done as methods on a new class but not always.

In this assignment, you'll be defining a collection of functions on strings, most of which already exist as methods on the str class. However, you should pretend that they don't already exist and define them as functions. Of course, you can't just use the existing methods. This will give you a bunch of practice on manipulating strings and also on defining functions.

In this assignment, you'll be defining a collection of functions on strings. You should define each of these as a new function with a function header as below. The description of each is in the comment supplied. Recall that strings are immutable, so you will have to return a new copy of the string for those that call for you to return a string. If you are returning the same string as the input, just return it; there is no need to make a new copy, and it wouldn't anyway.

The only string functions/methods to use:

ord, chr
indexing and slicing
append (i.e., ``+'')
len, in, not in
equality comparison (== or !=))
Looping over strings (while or for loops) and selection (if statements) are allowed. BUT You cannot convert the strings to other types such as lists.

Define each of the following functions, with semantics as indicated by the comment. In each of the following ch is a single character, str, str1, str2 are strings, and i is a non-negative integer. You do not have to validate the inputs, except as indicated; you can assume these types.

At least one question asks you to return two values. That really means returning a tuple (pair) of values. You do that as follows:

return value1, value2
This actually returns the pair (value1, value2). The caller can then assign the members of the pair to two variables:

x, y = pairReturningFunction() # assumes function returns a pair
z, w = (value1, value2) # assigning a tuple to 2 variables
If you like, you can use earlier functions in later ones, or define helper functions, though it shouldn't really be necessary. Note that some of these are trivial to write, while others are a bit harder. I have done the first one for you.

def myAppend( str, ch ):
# Return a new string that is like str but with
# character ch added at the end
return str + ch

def myCount( str, ch ):
# Return the number of times character ch appears
# in str.

def myExtend( str1, str2 ):
# Return a new string that contains the elements of
# str1 followed by the elements of str2, in the same
# order they appear in str2.

def myMin( str ):
# Return the character in str with the lowest ASCII code.
# If str is empty, print "Empty string: no min value"
# and return None.

def myInsert( str, i, ch ):
# Return a new string like str except that ch has been
# inserted at the ith position. I.e., the string is now
# one character longer than before. Print "Invalid index" if
# i is greater than the length of str and return None.

def myPop( str, i ):
# Return two results:
# 1. a new string that is like str but with the ith
# element removed;
# 2. the value that was removed.
# Print "Invalid index" if i is greater than or
# equal to len(str), and return str unchanged and None

def myFind( str, ch ):
# Return the index of the first (leftmost) occurrence of
# ch in str, if any. Return -1 if ch does not occur in str.

def myRFind( str, ch ):
# Return the index of the last (rightmost) occurrence of
# ch in str, if any. Return -1 if ch does not occur in str.

def myRemove( str, ch ):
# Return a new string with the first occurrence of ch
# removed. If there is none, return str.

def myRemoveAll( str, ch ):
# Return a new string with all occurrences of ch.
# removed. If there are none, return str.

def myReverse( str ):
# Return a new string like str but with the characters
# in the reverse order.

This code calculates the distance between points (1, 2) and (4, 6) using the Pythagorean Theorem, which yields a result of 5.0.

A Python function that calculates the distance between two coordinate pairs using the Pythagorean Theorem:

```python

import math

def distance(point1, point2):

   # Unpack the coordinate pairs into variables

   x1, y1 = point1

   x2, y2 = point2

   # Calculate the squared differences between x and y coordinates

   x_diff_sq = pow(x2 - x1, 2)

   y_diff_sq = pow(y2 - y1, 2)

   # Add the squared differences and take the square root of the result

   distance = math.sqrt(x_diff_sq + y_diff_sq)

   return distance

```

You can use this function by passing two tuples representing the coordinate pairs as arguments. For example:

```python

result = distance((1, 2), (4, 6))

print(result)  # Output: 5.0

```
