Question 3 You are working with the ToothGrowth dataset. You want to use the skim_without_charts() function to get a comprehensive view of the dataset. Write the code chunk that will give you this view.
Answers
There are different kinds of chunk options. The code chunk that will give me this view is skim_without_charts(ToothGrowth)
This code chunk can gives me a comprehensive view of the dataset. When you look into the parentheses of the skim_without_charts() function, you will see the name of the dataset that you intended looking into/viewing.
The code is known to return or give a short detail with the name of the dataset and the number of rows and columns therein.

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
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.

Square the difference between the y values.3. Add the two squares.4. Take the square root of the result.In order to compute the square root of something, you need to use the sqrt function. This function belongs to a module in Python called math. The first line of the code provided imports this module, so that you can use the functions in it. To take the square root of a number, simply do something like the following:number = ...result = math.sqrt(number)You can also use the built-in Python function pow to take the square of a number, like this:number = ...square = pow(number, 2)

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

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.

# If str is empty, print "Empty string: no min value"

# one character longer than before. Print "Invalid index" if
# i is greater than the length of str and return None.

# Return two results:
# 1. a new string that is like str but with the ith

Hope this helps !!What’s the relationship among speed frequency and the number of poles in a three phase induction motor
Answers
Answer:
The number of poles in the windings defines the motor's ideal speed. A motor with a higher number of poles will have a slower rated speed but a higher rated torque.
Explanation:
The relationship among speed, frequency, and the number of poles in a three-phase induction motor is governed by what is known as the synchronous speed equation.
The synchronous speed of an induction motor is the speed at which the rotating magnetic field generated by the stator windings of the motor rotates.
The synchronous speed (Ns) of a three-phase induction motor is given by the following equation:
Ns = (120 × f) / P
where:
Ns is the synchronous speed in revolutions per minute (RPM).
f is the supply frequency in hertz (Hz).
P is the number of poles.
From the equation, it can be observed that the synchronous speed is directly proportional to the frequency and inversely proportional to the number of poles.
This means that if the frequency increases, the synchronous speed also increases, assuming the number of poles remains constant.
Conversely, if the frequency decreases, the synchronous speed decreases.
The actual speed of an induction motor is known as the rotor speed or slip speed, which is always slightly lower than the synchronous speed. The difference between the synchronous speed and the actual speed is referred to as slip and is necessary for the motor to induce a voltage in the rotor and generate torque.
It's important to note that the synchronous speed equation assumes an ideal motor with no load. In practice, the actual speed of the motor depends on various factors, including the load torque, rotor resistance, and motor design.
