Question 1: a)Population Growth The world population data spans from 1960 to 2017. We'd like to build a predictive model that can give us the best guess at what the population growth rate in a given year might be. We will calculate the population growth rate as follows:- Growth_rate=current_year_population−previous_year_populationprevious_year_population As such, we can only calculate the growth rate for the year 1961 onwards. Write a function that takes the population_df and a country_code as input and computes the population growth rate for a given country starting from the year 1961. This function must return a return a 2-d numpy array that contains the year and corresponding growth rate for the country. Function Specifications: Should take a population_df and country_code string as input and return a numpy array as output. The array should only have two columns containing the year and the population growth rate, in other words, it should have a shape (?, 2) where ? is…
The ACT is a standardized test used by college admissions offices as a factor in whether an applicant is or is not admitted to their college. Since so many students take this test each year, the distribution of results are typically approximately normal. The table below shows the mean and standard deviation for each section of within the ACT for all test takers in the years 2015, 2016, and 2017. Section Mean Standard Deviation English 20.3 6.8 Math 20.7 5.4 Reading 21.4 6.5 Science 20.9 5.5 STEM 21.0 5.2 What are the z-score and the percentile rank of a student who scored 22 in the Math section of the ACT? z = percentile
Correct answer will be upvoted else downvoted. Focuses got by hopefuls in various stages are utilized for shaping generally challenge results. Assume that k phases of the challenge are finished. For every challenger, k−⌊k4⌋ stages with the most noteworthy scores are chosen, and these scores are added up. This total is the general aftereffect of the competitor. (Here ⌊t⌋ indicates adjusting t down.) For instance, assume 9 phases are finished, and your scores are 50,30,50,50,100,10,30,100,50. Initial, 7 phases with the most elevated scores are picked — for instance, all stages aside from the 2-nd and the 6-th can be picked. Then, at that point, your general outcome is equivalent to 50+50+50+100+30+100+50=430. At this point, n stages are finished, and you know the focuses you and Ilya got for these stages. Be that as it may, it is obscure the number of more stages will be held. You can't help thinking about what the most modest number of extra stages is, after which your outcome…
plz solve this in C. don't copy other people's code. thanks You are in charge of planning a holiday party for your organization at a venue nearby, which meant that you have to organize the details including food and activities. After researching the possibilities, you have considered three packages. Each package charges a minimum fee for the first hour of room rental, and an additional fee every hour in excess of the first hour. The maximum duration possible for reserving per day is 4 hours. There is a maximum charge for room rental for an event. Write a program that calculates and prints the total charge for a selected package, the duration, and food and activities (based on the number of people attending). Package First Hour of room rental (minimum) Hourly Cost after the First Hour Maximum room rental charge for an event Minimum number of guests Maximum number of guests Cost per person for food and activities #1 $50 $25 $95 50 200 $25…

A staff number of a BigHit company is composed of 2 non-vowels uppercase alphabets and 3 digit mumbers. i How many staffnumbers can be generated if the company requested to start the first letter with J and the 3 digit numbers (repetition not allowed)? ii. How many ways the staff number can be formed if it has any consonants and odd numbers with repetition allowed?
Step 1. Intersection over Union # def intersection_over_union(dt_bbox, gt_bbox): ---> return iou Step 2. Evaluate Sample We now have to evaluate the predictions of the model. To do this, we will write a function that will do the following: Take model predictions and ground truth bounding boxes and labels as inputs. For each bounding box from the prediction, find the closest bounding box among the answers. For each found pair of bounding boxes, check whether the IoU is greater than a certain threshold iou_threshold. If the IoU exceeds the threshold, then we consider this answer as True Positive. Remove a matched bounding box from the evaluation. For each predicted bounding box, return the detection score and whether we were able to match it or not. def evaluate_sample(target_pred, target_true, iou_threshold=0.5): # ground truth gt_bboxes = target_true['boxes'].numpy() gt_labels = target_true['labels'].numpy() # predictions dt_bboxes =…

Depending on the cause of death, racial/ethnic and gender disparities exist on years of potential life lost in the United States. Years of Potential Life Lost (YPLL) can be defined as the number of years lost when death occurs before one’s life expectancy. For this assignment, life expectancy will be set for everyone at 75. For YPLL, a death of a very young person is weighted more than a death of a very old person (Seabert, McKenzie, & Pinger, 2022). AS Instructions: Investigate one cause of death (infant mortality, homicide, suicide, unintentional injuries (such as car accidents, drowning, falling, etc.), pregnancy complications, COVID-19, etc.) in the United States and research the YPLL for racial/ethnic groups and genders. Summarize your findings in your paper and discuss how calculating YPLL can change the way we think about that particular cause of death differently. Provide factual documentation that reinforces your findings from at least three peer reviewed sources…
The Nobel peace prize is awarded to persons who excel in various fields ofendeavor. Currently only a handful of panel members determine and choose people who qualify for a particular award based on nomination from a wide range of disciplines’. This process of selecting the winners for the various prices have been criticized as being biased especially from the side of the panel members. The committee of experts at a general council meeting decided to automate the selection process. On a trial bases, you have been engaged to develop a java system that will automatically select a nominee as the winner of the award in two categories (peace and science). Your program should have the following functionalities. a) You are to define a class named Nobel_Award. Your class must have twofunctions, one of the functions should be named Award_Category, andthe other function should be named Award_Winner. YourAward_Category must have a string parameter list and return the stringwhen called. Your…
