please do 3 and 4 Thanks use the graph to answer 3 and 4

Solve for n using special segments of secants and tangents theoreom provide a detailed explanation of the algorithm that is used to fit a regression tree. Observation Use your senses to make an observation about your environment.Questions Create a hypothesis that can be tested in an experiment.Remember, a hypothesis has a specific "if then" wording. It describes what will happen to the dependent variablewhen changes are made to the independent variable. For example, "If a plant is fertilized (independent variable),then it will grow faster (dependent variable)." Design and plan an experiment.Be sure to identify an independent variable, a dependent variable, and any controls. Remember, controls are factorswhich stay the same. In an experiment designed to test the previously stated hypothesis, one control would be touse the same kind of plant. Write a complete description of your experiment. Include a list of necessary materials. Itis a good idea to follow a step-by-step procedure format. Think of everything you need to do, then write it down inthe order it must be completed. Your description and procedure should be clear enough that another person couldduplicate your experiment exactly. sandy is a 13-year-old girl who has begun to look at herself in the mirror many times each day; each time, she looks at image in the mirror and tries to judge how other people would see her. sandy is probably experiencing during an oxidation-reduction experiment, why is it important to observe the reaction after 30 minutes? responses the solution and solid look different after 30 minutes than when the reaction begins. the solution and solid look different after 30 minutes than when the reaction begins. the reaction requires time to complete. the reaction requires time to complete. silver continues to precipitate for 30 minutes. silver continues to precipitate for 30 minutes. all of the above all of the above An organization has developed an application that needs a patch to fix a critical vulnerability. In which of the following environments should the patch be deployed LAST?a. Testb. Stagingc. Developmentd. Production Maria buys a plastic rod that is 5 feet lorThe cost of the plastic rod is $0.35 per foot including tax. Find the total cost of the rod. let x1;x2; : : : are i.i.d. let z be the average z := (x1 + x2 + x3 + x4)=4 assume that the standard deviation of x1 is equal to 2. what is the standard deviation of z? You plan to deploy an Azure web app that will have the following settings:Name: WebApp1Publish: CodeRuntime stack: Java 11Operating system: LinuxContinuous deployment: DisableYou need to ensure that you can integrate WebApp1 with GitHub Actions.Which setting should you modify? 7.4.4: Array iteration: Sum of excess.Array testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.import java.util.Scanner;public class SumOfExcess {public static void main (String [] args) {Scanner scnr = new Scanner(System.in);final int NUM_VALS = 4;int[] testGrades = new int[NUM_VALS];int i;int sumExtra = -9999; // Assign sumExtra with 0 before your for loopfor (i = 0; i < testGrades.length; ++i) {testGrades[i] = scnr.nextInt();}/* Your solution goes here */System.out.println("sumExtra: " + sumExtra);}} HELLPPPPP PLEASEEEEEE PLEASEEEE Automobiles arrive at the drive-through window at the downtown Baton Rouge, Louisiana, post office at the rate of 2 every 10 minutes. The average service time is 2.0 minutes. The Poisson distribution is appropriate for the arrival rate and service times are negative exponentially distributed. a) The average time a car is in the system = 3.36 minutes (round your response to two decimal places). b) The average number of cars in the system = 0.67 cars (round your response to two decimal places). c) The average number of cars waiting to receive service = 0.27 cars (round your response to two decimal places). d) The average time a car is in the queue = 1.34 minutes (round your response to two decimal places). e) The probability that there are no cars at the window = 0.6 (round your response to two decimal places).f) The percentage of the time the postal clerk is busy = 40 % (round your response to the nearest whole number).g) The probability that there are exactly 2 cars in the system = 0.096 (round your response to three decimal places). suppose the roots of the auxiliary equation are as followsm1=-1 m2=-1 m3=2then the general solution for the third-order homogenous Cauchy Euler differential equation is Can words or terms in contracts that are subject to more than one reasonable interpretation lead to mistakes? CAN SOMEONE HELP WITH THIS QUESTION? Ashna Singh is the vice president of HR for Arcadia Bakeries, a large bread manufacturer. Recently, Adelaide Kramer, one of the best bakers in the company, approached her with a problem."Ashna, Ive got several people on my team who are having a hard time balancing their work and family lives. Either they have children at home or they care for elderly parents, and its just too hard for them to work a regular schedule. Is there anything we can do?"Ashna thought about it for a minute and responded, "I think so. Ive been hearing about some innovative flexible work schedules recently. Let me put some ideas together, and we can talk about it at the next company meeting."At the next company meeting, Ashna announced, "Starting next month, were going to implement a new flexible work schedule. All employees will be able to request part-time assignments. We will pair people who want to work part-time so that each work shift is covered."PART 1:Ashna is proposing a _____ plan.A. flextimeB. telecommutingC. job-sharingD. variable work schedule Read Romeos comment after killing Tybalt in Act III, scene i of Romeo and Juliet.Romeo: O!
