Compare and contrast predictive analytics with prescriptive and descriptive analytics. Use examples.
Explanation:
Predictive, prescriptive, and descriptive analytics are three key approaches to data analysis that help organizations make data-driven decisions. Each serves a different purpose in transforming raw data into actionable insights.
1. Descriptive Analytics:
Descriptive analytics aims to summarize and interpret historical data to understand past events, trends, or behaviors. It involves the use of basic data aggregation and mining techniques like mean, median, mode, frequency distribution, and data visualization tools such as pie charts, bar graphs, and heatmaps. The primary goal is to condense large datasets into comprehensible information.
Example: A retail company analyzing its sales data from the previous year to identify seasonal trends, top-selling products, and customer preferences. This analysis helps them understand the past performance of the business and guide future planning.
2. Predictive Analytics:
Predictive analytics focuses on using historical data to forecast future events, trends, or outcomes. It leverages machine learning algorithms, statistical modeling, and data mining techniques to identify patterns and correlations that might not be evident to humans. The objective is to estimate the probability of future occurrences based on past data.
Example: A bank using predictive analytics to assess the creditworthiness of customers applying for loans. It evaluates the applicants' past financial data, such as credit history, income, and debt-to-income ratio, to predict the likelihood of loan repayment or default.
3. Prescriptive Analytics:
Prescriptive analytics goes a step further by suggesting optimal actions or decisions to address the potential future events identified by predictive analytics. It integrates optimization techniques, simulation models, and decision theory to help organizations make better decisions in complex situations.
Example: A logistics company using prescriptive analytics to optimize route planning for its delivery truck fleet. Based on factors such as traffic patterns, weather conditions, and delivery deadlines, the algorithm recommends the best routes to minimize fuel consumption, time, and cost.
In summary, descriptive analytics helps organizations understand past events, predictive analytics forecasts the likelihood of future events, and prescriptive analytics suggests optimal actions to take based on these predictions. While descriptive analytics forms the foundation for understanding data, predictive and prescriptive analytics enable organizations to make proactive, data-driven decisions to optimize their operations and reach their goals.

#this is 34 lines -- you can do it! # #In web development, it is common to represent a color like #this: # # rgb(red_val, green_val, blue_val) # #where red_val, green_val and blue_val would be substituted #with values from 0-255 telling the computer how much to #light up that portion of the pixel. For example: # # - rgb(255, 0, 0) would make a color red. # - rgb(255, 255, 0) would make yellow, because it is equal # parts red and green. # - rgb(0, 0, 0) would make black, the absence of all color. # - rgb(255, 255, 255) would make white, the presence of all # colors equally. # #Don't let the function-like syntax here confuse you: here, #these are just strings. The string "rgb(0, 255, 0)" #represents the color green. # #Write a function called "find_color" that accepts a single #argument expected to be a string as just described. Your #function should return a simplified version of the color #that is represented according to the following rules: # # If there is more red than any other color, return "red". # If there is more green than any other color, return "green". # If there is more blue than any other color, return "blue". # If there are equal parts red and green, return "yellow". # If there are equal parts red and blue, return "purple". # If there are equal parts green and blue, return "teal". # If there are equal parts red, green, and blue, return "gray". # (even though this might be white or black). #Write your function here!
Answer:
Following are the code to this question:
def find_color(color):#definig a method find_color that accepts color parameter
color = str(color).replace('rgb(', '').replace(')', '')#definig color variable that convert parameter value in string and remove brackets
r, g, b = int(color.split(', ')[0]), int(color.split(', ')[1]), int(color.split(', ')[2])#defining r,g,b variable that splits and convert number value into integer

Explanation:
In the above method "find_color" is declared that uses the color variable as the parameter, inside the method a color variable is declared that convert method parameter value into the string and remove its brackets, and three variable "r,g, and b" is defined. In this variable first, it splits parameter value and after that, it converts its value into an integer and uses the multiple conditional statements to return its calculated value.
if block checks the r, g, and b value it all value is equal it will return a string value, that is "gray" otherwise it will go to elif block. In this block, it checks the value of r is greater then g, and b if it is true it will return a string value, that is "red" otherwise it will go to another elif block. In this block, it checks the value of b is greater then g, and r if it is true it will return a string value, that is "blue" otherwise it will go to another elif block. In this block, it checks the value of g is greater then r and b if it is true it will return a string value, that is "green" otherwise it will go to another elif block. In the other block, it checks r is equal to g or g is equal to b or r is equal to b, it will return the value, that is "yellow" or "teal" or "purple".Transmissions in wireless networks do not allow for collision detection but try to avoid collision. Briefly describe this process and explain why it is termed as unreliable.
Transmissions in wireless networks do not allow for collision detection but try to avoid collision and also It is especially crucial for wireless networks since wireless transmitters desensing (turning off) their receivers during packet transmission prevents the option of collision detection using CSMA/CD.
What are the different types of wireless transmission?Wireless transceivers are unable to send and receive on the same channel simultaneously, hence they are unable to identify collisions. This is because the send power (which is typically around 100mw) and the receive sensitivity have such a huge disparity (commonly around 0.01 to 0.0001mw).
Therefore, Infrared, broadcast radio, cellular radio, microwaves, as well as communications satellites are examples of wireless transmission media that are used in communications. Infrared (IR), which is a wireless transmission medium that uses infrared light waves to transmit signals, was covered previously in the chapter.

b) Find angle between vectors u and v.
c) Graph both u and v on the same system.
d) Now, graph vectors u, v and on the same set of axes and give u * v a different color than vectors u and v.
e) Rotate graph from part d and show two different views of the cross product.
f) Find the normal vector to vector u.
a) To find the dot product of the vectors u and v, we can use the Dot function in Mathematica. The dot product is calculated as follows:
u.v = Dot[u, v]
b) To find the angle between vectors u and v, we can use the ArcCos function in Mathematica. The angle is calculated as follows:
angle = ArcCos[(u.v)/(Norm[u]*Norm[v])]
c) We can graph both vectors u and v on the same system using the ListVectorPlot3D function in Mathematica. This will display the vectors in a 3D coordinate system.
ListVectorPlot3D[{u, v}]
d) To graph vectors u, v, and u * v on the same set of axes with different colors, we can use the Graphics3D function in Mathematica. We can assign a different color to u * v using the Directive function.
Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],
Directive[Red], Arrow[{{0, 0, 0}, u*v}]}]
e) To rotate the graph from part d and show two different views of the cross product, we can use the ViewPoint option in the Graphics3D function. By specifying different viewpoints, we can obtain different perspectives of the graph.
Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],
Directive[Red], Arrow[{{0, 0, 0}, u*v}]},
ViewPoint -> {1, -1, 1}]
Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],
Directive[Red], Arrow[{{0, 0, 0}, u*v}]},
ViewPoint -> {1, 1, 1}]
f) To find the normal vector to vector u, we can use the Cross function in Mathematica. The normal vector is calculated as follows:
normal = Cross[u]
The function Cross[u] computes the cross product of u with the standard basis vectors. The resulting vector represents the direction perpendicular to the plane spanned by u.

Consider the method get Hours, which is intended to calculate the number of hours that a vehicle takes to travel between two mile markers on a highway if the vehicle travels at a constant speed of 60 miles per hour. A mile marker is a sign showing the number of miles along a road between some fixed location (for example, the beginning of a highway) and the current location. IN The following table shows two examples of the intended behavior of getHours, based on the int parameters markeri and marker2. marker1 marke 100 220 100 700.5 Consider the following implementation of getHours. public static double getHours (int markeri, int ON 20 | 2 15. . . e no E /* missing statement */ return hours; Which of the following statements can replace /* missing statement */ so getHours works as intended?
(A) double hours = (Math.abs (markerl) - Math.abs (marker2)) / 60.0;||
(B) double hours = Math.abs (markeri - marker2 / 60.0)
(C) double hours = Math.abs (marker1 - marker2) / 60.0;
(D) double hours = Math.abs((markeri - marker2) / 60);
(E) double hours = (double) (Math.abs (marker1 - marker2) / 60);
Answer:
Replace the comment with:
(c) double hours = Math.abs (marker1 - marker2) / 60.0;
Explanation:
See attachment for right presentation of question
Analyzing the options:
(a): May return a negative result
This option will return a negative value if marker1 is less than marker2 because it subtracts the absolute value of marker2 from the absolute value marker1.
This literally is not different from marker1 - marker2
(b): Incorrect expression
This divides only marker2 by 60, then subtracts the quotient from marker1. This is not the expected expression.
(c) This option is correct
This correctly calculate the positive difference between marker1 and marker2 and the result is divided by 60.0 (note 60.0 not 60)
(d) & (e) Integer division
When a variable declared as double is divided by an integer variable or value, the result of the computation is not always accurate due to approximation
What is the environmental Impact of your favourite food?
With the fruit/vegetable you chose in E03, and the information you gathered, compute the environmental impact of the product system using LCA.
Your computation must at least consider the processes of production of the fruit/vegetable and the transportation of the fruit/vegetable from the “farm” to the grocery store (or where you bought it from).
You can use the automated tools provided by OpenLCA to do this easily.
OpenLCA Nexus has a collection of datasets, e.g., the Agribaylase dataset which contains existing LCA and LCI studies, which you can use to model your product system.
The Information you gathered in E03 about your favourite food, can help fill in the gaps in the generic data provided in the various datasets and increase the accuracy of your impact assessment.
A general overview of how the environmental impact of a food item can be calculated using Life Cycle Assessment (LCA).
LCA is a methodology used to assess the environmental impacts of a product system throughout its entire life cycle, from production to disposal.
To calculate the environmental impact of a food item, LCA would consider factors such as the use of pesticides and fertilizers during farming, the energy and resources required for processing and transportation, and the amount of waste generated.
For example, if we were to consider the environmental impact of a banana, LCA would take into account the carbon emissions from transportation, the water usage and pesticide/fertilizer application during farming, and the waste generated during packaging and disposal.
LCA can provide valuable insights into the environmental impact of a food item, allowing for more informed decision-making and the development of sustainable practices in the food industry.

Which part of the Result block should you evaluate to determine the needs met rating for that result
To know the "Needs Met" rating for a specific result in the Result block, you should evaluate the metadata section of that result.
What is the Result blockThe assessment of the metadata section is necessary to determine the rating of "Needs Met" for a particular outcome listed in the Result block.
The metadata includes a field called needs_met, which evaluates the level of satisfaction with the result in terms of meeting the user's requirements. The needs_met category usually has a score between zero and ten, with ten implying that the outcome entirely fulfills the user's demands.
