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 (McKenzie, Pinger, & Seabert, 2018). 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.
Correct and detailed answer will upvoted else downvoted . Skip if you don't know. there live N individuals, numbered from 1 to N. There are by and large M sets of individuals that are companions with one another. Individuals of Baltia need to put together a fruitful party, however they have extremely severe guidelines on what a party is and when the party is effective. On the island of Baltia, a party is a social occasion of precisely 5 individuals. The party is viewed as effective if either every one individuals at the party are companions with one another (so they would all be able to converse with one another without stressing over conversing with somebody they are not companions with) or no two individuals at the party are companions with one another (so everybody can simply be on their telephones without any other person troubling them). If it's not too much trouble, help individuals of Baltia put together a fruitful party or let them know that it's difficult to do as such.…
Each person in a group of n persons (n >= 4) has independent information known only to themselves. Whenever a person calls another person in the group, they exchange all the information they know at the time of calling. Design a sequence of calls (specifying the persons involved in each call) that they have to make in order to ensure that everyone knows all the information. How many calls are there in your scheme?
Every patient has a primary physician. Every doctor has at least one patient. Each pharmacy sells several drugs and has a price for each. A drug could be sold at several pharmacies, and the price could vary from one pharmacy to another. Doctors prescribe drugs for patients. A doctor could prescribe one or more drugs for several patients, and a patient could obtain prescriptions from several doctors. Each prescription has a date and a quantity associated with it. You can assume that, if a doctor prescribes the same drug for the same patient more than once, only the last such prescription needs to be stored. Pharmaceutical companies have long-term contracts with pharmacies. A pharmaceutical company can contract with several pharmacies, and a pharmacy can contract with several pharmaceutical companies. For each contract, you have to store a start date, an end date, and the text of the contract. Pharmacies appoint a supervisor for each contract. There must always be a supervisor for each…
Consider the elliptic curve group based on the equation where a = 1405, b = 2011, and p = 2531. We will use these values as the parameters for a session of Elliptic Curve Diffie-Hellman Key Exchange. We will use P = (0,98) as a subgroup generator. You may want to use mathematical software to help with the computations, such as the Sage Cell Server (SCS). On the SCS you can construct this group as: G=EllipticCurve(GF(2531),[1405,2011]) Here is a working example. (Note that the output on SCS is in the form of homogeneous coordinates. If you do not care about the details simply ignore the 3rd coordinate of output.) 62 Alice selects the private key 41 and Bob selects the private key 20. What is A, the public key of Alice? y² = x³ + ax+b mod p What is B, the public key of Bob? 2472 After exchanging public keys, Alice and Bob both derive the same secret elliptic curve point TAB. The shared secret will be the x-coordinate of TAB. What is it?
Correct answer will be upvoted else downvoted. Computer science. You are permitted to alter the marks through the accompanying activity: Pick two particular integers I and j among 1 and n. Trade the marks of focuses I and j, lastly Draw the section between focuses I and j. A grouping of tasks is legitimate if in the wake of applying every one of the activities in the succession all together, the k-th point winds up having the name k for all k among 1 and n comprehensive, and the drawn sections don't meet each other inside. Officially, assuming two of the portions cross, they should do as such at a typical endpoint of the two sections. Specifically, all drawn portions should be unmistakable. Track down any legitimate arrangement of activities, or say that none exist. Input The main line contains an integer n (3≤n≤2000) — the number of focuses. The I-th of the accompanying n lines contains three integers xi, yi, man-made intelligence (−106≤xi,yi≤106,…
Theoretical Overview Suppose we have a set of data consisting of ordered pairs and we suspect the x and y coordinates are related. It is natural to try to find the best line that fits the data points. If we can find this line, then we can use it to make all sorts of other predictions. In this project, we're going to use several functions to find this line using a technique called least squares regression. The result will be what we call the least squares regression line (or LSRL for short). In order to do this, you'll need to program a statistical computation called the correlation coefficient, denoted by r in statistical symbols: NOTE: Equation is written assuming you start at the value 1. Lists start at index 0. Once you have the correlation coefficient, you use it along with the sample means and sample standard deviations of the x and y-coordinates to compute the slope and y-intercept of your regression line via these formulas: Tasks: In this project, you must read…

To start with, the arrangement is unfilled. In one turn a player can eliminate a number from the left or right half of the exhibit and add it to the arrangement. The standard is that the grouping they are building should be completely expanding. The champ is the player that takes the last action. Alice is playing first. Given the beginning cluster, under the presumption that the two of them play ideally, who dominates the game? Input :The main line contains one integer N (1≤N≤2∗105) - the length of the exhibit A. The subsequent line contains N integers A1, A2,...,AN (0≤Ai≤109) Output :The solitary line of output comprises of one string, the name of the victor. On the off chance that Alice won, print "Alice", in any case, print "Weave".
ASSIGNMENT The Injury Severity Score (ISS) is a medical score to assess trauma severity. Data on ISS and hospital stay (in days) have been collected from a number of patients who were admitted to hospital after accidents. The ISS data are [64 35 50 46 59 41 27 39 66], and the length of stay data are [8 2 55 4 3 1 4 6]. Use MATLAB to plot the relationship between ISS and hospital stay.A
Let's revisit our first problem, where we want to set up a series of chess matches so we can rank six players in our class. As we did before, we will assume that everyone keeps their chess rating a private secret; however, when two players have a chess match, the person with the higher rating wins 100% of the time. But this time, we are only interested in identifying the BEST of these six players and the WORST of these six players. (We don't care about the relative ordering or ranking of the middle four players.) Your goal is to devise a comparison-based algorithm that is guaranteed to identify the player with the highest rating and the player with the lowest rating. Because you are very strong at Algorithm Design, you know how to do this in the most efficient way. Here are five statements. A. There exists an algorithm to solve this problem using 6 matches, but there does not exist an algorithm using only 5 matches. B. There exists an algorithm to solve this problem using 7 matches,…
Computer science. Correct answer will be upvoted else downvoted. There are n rockers, numbered from 1 to n from left to right. A few easy chairs are involved by individuals (at most one individual for each rocker), others are not. The number of involved rockers isn't more noteworthy than n2. For reasons unknown, you might want to advise individuals to move from their rockers to some different ones. In the event that the I-th easy chair is involved by somebody and the j-th rocker isn't, you can perceive the individual sitting in the I-th rocker to move to the j-th rocker. The time it takes an individual to move from the I-th rocker to the j-th one is |i−j| minutes. You might play out this activity quite a few times, however these tasks should be done consecutively, i. e. you can't see an individual to move until the individual you requested to move in the last activity has completed the process of moving to their objective easy chair. You need to accomplish the accompanying…
A basketball league wants to keep track of its teams and players. For each team, they need to track the name, city, and the number of years the team has been in the league. A city can host multiple teams, but a team can only ever represent one city. They also wish to store the population of each city. Multiple players play for each team (a new team might not yet have any players). For each player, the league wants to keep track of the first and last names, and the player’s jersey number. They only track the player’s most recent team – no historical data are stored. One and only one player on each team is designated the captain – this also needs to be stored. Each team is owned by one or more owners. For each owner, they need to track to the first and last name, all of the owner’s phone numbers, and the percentage of the team that each owner owns. Owners can own more than one team at the same time. At the end of the season, the league needs to publish a season-end report that…
