Suppose that each of the 300 million people in the United States fully consumes two packages of goods a day bearing RFID tags. How many RFID tags have to be pro- duced annually to meet that demand? At a penny a tag, what is the total cost of the tags? Given the size of GDP, is this amount of money going to be an obstacle to their use on every package offered for sale?

A call center has 60 employees on‐line, each of whom make one phone call every 3 min on average, and talk on average for 2 min. Each call costs 15¢. What is the total traffic in erlangs? How many circuits are required for a GoS of 1%? How much should the yearly (250 working days, 8 working hours a day) lease price be for the company to make a 50% saving in its telephone bills over the first 3 years? Assume the lease set‐up fee of $30,000 should be paid over a period of 3 years.
Consider a lengthy rural road (which can be considered to be a line segment with an eastern endpoint and a western endpoint). Along the road, residences are thinly spaced. Your challenge is to decide where to locate mobile phone base stations along the road in such a way that the total number of base stations is minimised and each residence is within four miles of a base station. Now, provide an efficient solution to this issue. Nota bene: you must demonstrate that your algorithm is valid.

Stanford University researchers published an MIT working paper titled “The Economics of Ride Hailing: Driver Revenue, Expenses, and Taxes” (February 2020). One of the objectives of the study was to determine whether ride-share drivers at Uber and Lyft actually make a profit. Data collected from a sample of 1,121 ride-share drivers yielded a mean monthly profit �¯=$661 with standard deviation �=$583. An Uber executive reports that �, the true mean monthly profit of all its ride-share drivers, is $1,000. You want to test the executive’s figure using �=.10. Set up the null and alternative hypotheses for the test. Assume that you believe the true mean monthly profit is less than $1,000. Find the rejection region for the test. Compute the test statistic. Use statistical software to find the p-value for the test. What is your conclusion? Show that the conclusion is the same whether you use the rejection region or p-value.
Suppose you want to pay back someone with 28 BDT and you have unlimited supply of 1 taka, 2 taka, 5 taka and 10 taka notes. Your target is to use the minimum number of notes to payback the said amount of money. How will you pay him/her back? That means how many notes of which value will you choose?
Pretend you have five employees who would like to know exactly how much their bi-weekly pay will be once all of their deductions are taken off. Their weekly pay is as follows: Emp #1. $1100 Emp #2. $1300 Emp #3. $1500 Emp #4. $1700 Emp #5. $2300 *Taxation *

Department 3 has 2500 hours. Transfers are allowed to departments 2 and 4, and from departments 1 and 2. If Ai measures the labor hours allocated to department i and Tij the hours transferred from department i to department j, then a.T13 + T23 − T32 − T34 − A3 = 2500. b.A3 + T13 + T23 − T32 − T34 = 2500. c.T31 + T32 − T23 − T43 + A3 = 2500. d.A3 − T13 − T23 + T32 + T34 = 2500.
Create a curve that uses a quadratic parametric approach with three interpolated control points. The equations which describe the curve are: $$f_x(u) = c_0 u^2 + c_1 u + c_2 $$ and $$f_y(u) = c_3 u^2 + c_4 u + c_5 $$ where $u$ ranges from 0.0 to 1.0. The first control point $$p_0$$ is for $u=0$, the second $p_1$ for $u=0.5$, and the third for $p_2$ and at $u=1.0$. Modify the code to implement your solution. It is sufficient for this task to get the program working with three control points, but you are most welcome to attempt a solution that works on four or more.

There are many sensors on a wind turbine, based on each sensor's reading many alerts are generated as (start, end). For easier monitoring, our customer is asking to raise alerts on the turbine level instead of on each sensor. If any sensor is having an alert, there should be an alert for the entire wind turbine. Suppose the alerts created with two sensors readings are [(0,3),(5,10),(1,4),(10,15)], then the turbine level alert should be [(0,4),(5,15)]. Return the alerts sorted by the start timestamp. If there is no alert from the sensor level, return an empty array []. Code needs to be in Python?
You found an exciting summer job for five weeks. It pays, say, $15.50 per hour. Suppose thatthe total tax you pay on your summer job income is 14%. After paying the taxes, you spend10% of your net income to buy new clothes and other accessories for the next school yearand 1% to buy school supplies. After buying clothes and school supplies, you use 25% of theremaining money to buy savings bonds. For each dollar you spend to buy savings bonds,your parents spend $0.50 to buy additional savings bonds for you. Write a flowchart that prompts the user to enter the number of hours you worked each week. The program thenoutputs the following:a. Your income before and after taxes from your summer job.b. The money you spend on clothes and other accessories.c. The money you spend on school supplies.d. The money you spend to buy savings bonds.e. The money your parents spend to buy additional savings bonds for you.
