Question 1 (10 points). (a) Explain the difference between linear and logistic regression. (Explain at least two differences and one similarity in detail). (b) Give an example of a modeling problem (ie, using X to predict Y, where X and Y are real life examples) for each type.
Answer:
(a) Linear regression is used to estimate dependent variable which is continuous by using a independent variable set. Logistic regression we predict the dependent variable which is categorical using a set of independent variables.
(b) Finding the relationship between the Number of doors in the house vs the number of openings. Suppose that the number of door is a dependent variable X and the number of openings is an independent variable Y.
Step-by-step explanation:
(a) Linear regression is used to estimate dependent variable which is continuous by using a independent variable set .whereas In the logistic regression we predict the dependent variable which is categorical using a set of independent variables. Linear regression is regression problem solving method while logistic regression is having use for solving the classification problem.
(b) Example: Finding the relationship between the Number of doors in the house vs the number of openings. Suppose that the number of door is a dependent variable X and the number of openings is an independent variable Y.
If I am to predict that increasing or reducing the X will have an effect on the input variable X or by how much we will make a regression to find the variance that define the relationship or strong relationship status between them. I will run the regression on any computing software and check the stats result to measure the relationship and plots.

Step-by-step explanation:
The following pie chart shows the number of rabbits, sheep, cattle, pigs on a farm rabbits 900 sheep 700 cattle 300 Pig 500 a. How many animals are on the farm? b.What represents the number of sheep on the farm c. what percentage of the total number of animals are rabbits d. Calculate the angle that represents number of pigs
a) There are 2400 animals on the farm.
b) The number of sheep on the farm is 700.
c) The percentage of rabbits in relation to the total number of animals is 37.5%.
d) The angle that represents the number of pigs is 75 degrees.
a) To determine the total number of animals on the farm, we add up the number of rabbits, sheep, cattle, and pigs:
Total number of animals = 900 (rabbits) + 700 (sheep) + 300 (cattle) + 500 (pigs) = 2400 animals.
b) The number of sheep on the farm is given as 700.
c) To calculate the percentage of rabbits in relation to the total number of animals, we divide the number of rabbits by the total number of animals and multiply by 100:
Percentage of rabbits = (900 / 2400) * 100 = 37.5%.
d) To calculate the angle that represents the number of pigs, we need to find the proportion of the total number of animals that pigs make up, and then convert it to an angle on the pie chart.
Proportion of pigs = 500 / 2400 = 0.2083.
To find the angle in degrees, we multiply the proportion by 360 degrees:
Angle representing pigs = 0.2083 * 360 = 75 degrees.

4b + 11 + 8b + 1 = 180
Answer:
b=14
Step-by-step explanation:
Add 4b and 8b, which you get 12b. Then you add 11 and 1 which you get 12.
12b + 12 = 180 is the next equation.
Afterwards, you subtract 12 from 180.
12b = 168
Divide 12b from 168.
b = 14
Find for B?
Mk in this equation
4b + 11 + 8b + 1 = 180
Subtract 11 and 1 from both sides
4b + 8b = 168
Combine unknowns
12b = 168
Find b by dividing by 12
Thus, B = 14

Answer:
The formula for the area is πr² where r is the radius.
But the radius wasn't given so we have to ring it via the circumference given.
Step-by-step explanation:
Circumference = 87.92
To find the radius;
The formula for finding the circumference is 2πr. Therefore;
\(87.92 = 2\pi r \\ \pi = 3.14 \\ therefore \\ 87.92 = 2 \times 3.14r \\87.92 = 6.28r \\ we \: have \: to \: make \: r \: the \: subject \\ r = \frac{87.92}{6.28} \\ = 14 \)
So now that we have our radius to be 14 we substitute it into the equation for finding the area
\(area = \pi {r}^{2} \\ r = 14 \\ therefore \\ area = 3.14 \times {14}^{2} \\ = 3.14 \times 196 \\ = 615.44 \: square \: inches\)

Answer:
The decoded message is: "Steve Jobs".
Step-by-step explanation:
The given code is a sequence of binary digits, which represents the ASCII code of a message in binary form. To decode the message, we need to convert each 8-bit binary sequence into its corresponding ASCII character.
1010011 1110100 1100101 1110110 1100101 0100000 1001010 1101111 1100010 1110011
To decode this message, we split it into 8-bit sequences:
01010011 --> 'S'
01110100 --> 't'
01100101 --> 'e'
01110110 --> 'v'
01100101 --> 'e'
00100000 --> ' '
01001010 --> 'J'
01101111 --> 'o'
01100010 --> 'b'
01110011 --> 's'
Therefore, the decoded message is: "Steve Jobs".
Answer:
The decoded message is: "Steve Jobs"
Step-by-step explanation:
Converting the binary code to ASCII, we get:
01010011 = S
1110100 = t
1100101 = e
1110110 = v
1100101 = e
0100000 = (space)
1001010 = J
1101111 = o
1100010 = b
1110011 = s
So the decoded message is: "Steve Jobs"
----------------
Here are the steps to decode the given binary code:
Break the binary code into groups of 8 digits, as each group represents a single ASCII character.
Convert each group of 8 digits into its corresponding ASCII character using a binary-to-text converter or an ASCII code chart.
Write down the decoded ASCII characters in the order in which they appear in the original binary code.
Let's follow these steps to decode the given binary code:
The given binary code is: 1010011 1110100 1100101 1110110 1100101 0100000 1001010 1101111 1100010 1110011
We break this binary code into groups of 8 digits:
1010011 = 53
1110100 = 74
1100101 = 65
1110110 = 76
1100101 = 65
0100000 = 32
1001010 = 74
1101111 = 111
1100010 = 98
1110011 = 115
We convert each group of 8 digits into its corresponding ASCII character using an ASCII code chart:
53 = S
74 = t
65 = e
76 = v
65 = e
32 = (space)
74 = J
111 = o
98 = b
115 = s
We write down the decoded ASCII characters in the order in which they appear in the original binary code:
Decoded message: "Steve Jobs"
ASCII mean?
ASCII stands for American Standard Code for Information Interchange. It is a character encoding standard that assigns unique numeric codes to represent text characters. The ASCII standard includes codes for uppercase and lowercase letters, digits, punctuation marks, and various other symbols. Each ASCII character is represented by a unique 7-bit binary code, allowing computers and other devices to communicate and display text in a consistent manner. The ASCII standard was first published in 1963 and has since been expanded and updated to include additional characters and support for different languages.
