s to write a Python-program that uses training data to choose the four ideal functions which are the
best fit out of the fifty provided (C) *.
i) Afterwards, the program must use the test data provided (B) to determine for each and every x-ypair of values whether or not they can be assigned to the four chosen ideal functions**; if so, the
program also needs to execute the mapping and save it together with the deviation at hand
ii) All data must be visualized logically
iii) Where possible, create/ compile suitable unit-test
* The criterion for choosing the ideal functions for the training function is how they minimize the sum of all ydeviations squared (Least-Square)
** The criterion for mapping the individual test case to the four ideal functions is that the existing maximum
deviation of the calculated regression does not exceed the largest deviation between training dataset (A) and
the ideal function (C) chosen for it by more than factor sqrt(2
Answers
Use the knowledge in computational language in python is possible write the data about a function and the summation.
How to define function in Python?In Python, a function is a sequence of commands that performs some task and that has a name. Its main purpose is to help us organize programs into chunks that correspond to how we envision a solution to the problem.
So in an easier way we have that the code is:
def plus(a,b):
return a + b
class Summation(object):
def sum(self, a, b):
self.contents = a + b
return self.contents
sumInstance = Summation()
sumInstance.sum(1,2)

An IT infrastructure manager is reviewing his company's computer assets, particularly the mean time to failure (MTTF) of the PC and server hard drives. The manufacturer of the hard drives typically used in the company states that the MTTF is approximately 11 years. Because servers and some high-priority workstations must operate continuously except for brief periods of maintenance, how many hours, on average, can these hard drives be expected to operate before failure
Answers
The numbers of hours, on average, can these hard drives be expected to operate before failure is 24 hours a day, also seven days a week and 365 days a year.

Thirty percent of a magazine's subscribers are female. A random sample of 50 subscribers Answer the following questions using Excel: (using standart devision of 0.0648)
a. What is the probability that the proportion of females from this sample is at most 0.25
b. What is the probability that the proportion of females from this sample is between 0.22 and 0.28
c. What is the probability that the proportion of females from this sample is within 0.03 of the population proportion?
Answers
Based on the mean of the subscribers, the sample size, and the standard deviation, the probability of females being at most 0.25 is 0.2202.
The probability that they are between 0.22 and 0.28 is 0.2703.
The probability that they are within 0.03 of the population proportion is 0.3566.
What is the probability that they are at most 0.25?Using Excel, we shall assume that the distribution is normally distributed.
We can therefore use the NORM.DIST function:
=NORM.DIST(0.25,0.3,0.0648,TRUE)
= 0.2202
What is the probability that they are between 0.22 and 0.28?=NORM.DIST(0.28,0.3,0.0648,TRUE) - NORM.DIST(0.22,0.3,0.0648,TRUE)
= 0.2703
What is the probability that they are within 0.03 of the population proportion?X high = 0.30 + 0.03
= 0.33
X low = 0.30 - 0.03
= 0.27
= NORM.DIST(0.33,0.3,0.0648,TRUE) - NORM.DIST(0.27,0.3,0.0648,TRUE)
= 0.3566.

Suppose that you have a computer with a memory unit of 24 bits per word. In this
computer, the assembly program’s instruction set consists of 198 different operations.
All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory.
1. How many bits are needed for the opcode?
2. How many bits are left for the address part of the instruction?
3. How many additional instructions could be added to this instruction set without
exceeding the assigned number of bits? Discuss and show your calculations.
4. What is the largest unsigned binary number that the address can hold?
Answers
Answer:
a ) The amount of bits required for the opcode
8 bits
2^8= 256
256>198
We get the next lower number, which is 2^7 = 128 bits, because it is greater than 198. As a result, the operation code necessitates 8 bits.
b) The number of bits reserved for the instruction's address.
16 bits
24-8 = 16
c)
65536
2^16 = 65536
Maximum number = 65535
