58. You are responsible for valuing the inventory of a crude oil depot based on daily closing prices, and you havecreated a spreadsheet to help you. The cells in column A tell the ownership status of individual grades of oil(Holding or Not Holding), column B reports the closing price, and column C issues instructions based on theclosing price (Bid, Offer, or Do Nothing). The rules for taking action are as follows:If the closing price is >=$75 and we own the oil, we will Offer it for sale.If the closing price is <=$55 and we do not own the oil, we will Bid for its acquisition.Otherwise, we will Do Nothing.What formula should you enter in cell C2 to conduct this analysis?€IF(A2="Holding", B2>=75), "Offer",IF((A2="Not Holding",B2<=55), "Acquire","Do Nothing"))IF(AND(A2="Holding", B2>=75), "Offer",IF(AND(A2="Not Holding", B2<=55),"Offer","Do Nothing"))IF(AND(A2="Not Holding", B2>=75), "Offer",IF(AND(A2=" Holding", B2<=55), "Bid","Do Nothing"))IF(AND(A2="Holding", B2>=75),"Offer",IF(AND(A2="Not Holding", B2<=55),"Acquire", "Do Nothing"))27

Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, I-405 services I-5, and I-290 services I-90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 the output is: I-90 is primary, going east/west. Ex: If the input is: 290 the output is: I-290 is auxiliary, serving I-90, going east/west. Ex: If the input is: 0 or any number not between 1 and 999, the output is: 0 is not a valid interstate highway number.

The following image shows 4 boxes containing different balls labelled by numbers between 1 and 9. 4 2 (8) (5 7 5 The boxes are used in a lottery to determine a winning combination of 4 numbers by drawing one ball from each box. To enter the lottery, participants write 4 numbers between 1 and 9 on their ticket in nondecreasing order (from smallest to largest). A ticket wins if all its numbers are drawn in the lottery. The order in which the numbers are drawn does not matter. For example, if the drawing is (2, 8, 2, 1), then a ticket with the numbers (1, 2, 2, 8) wins (the numbers are the same, albeit in a different order), but a ticket with the numbers (1, 2, 2, 9) loses. Construct a list of all valid tickets, i.e., all tickets that can potentially be drawn in the lottery, and store it in the variable possible_tickets. The tickets should be specified as tuples of 4 numbers in nondecreasing order, and every valid ticket should appear exactly one time in the list possible_tickets. (Note,…
Q3. A company has 45 employers, 25 work as system developers (D) and (N) work as sales representer while (M) of them work as IT technicians. This company deals with 450 products. In the products table, each product has a name, price, size, and weight. A. Draw a flowchart to find the product that has very heavy weight. B. Draw a flowchart to find how many numbers of the products have a Small size(s), where there are 3 product sizes (S, M, L). ':
A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is: 1712 the output is: 1712 - leap year Ex: If the input is: 1913 the output is: 1913 - not a leap year
Python code for this scenario: There is a line of tourist trying to book a room for their vacation. The rates for each room is available below. The guest are allowed to book any room for any duration. Rate per day: A - Junior Suite (1500) B - Deluxe Suite (3600) C - Executive Suite (7800) Input: Number of guests: Name of guests: Letter of their room choice and the number of room: Duration of stay: Customer payment: Process: - The accommodation should be inputted as a string. If the value is not applicable, just ignore that item. - The duration of their stay will be arranged in ascending order to know who will check out soon Output: Guest names in ascending order based on the duration of their stay. Calculate your total sales and the total change. Example: Book now! Rate per day: A - Junior Suite (1500) B - Deluxe Suite (3600) C - Executive Suite (7800) Number of guests: 3 Name of guests: Moon Rose Sky Letter of their room choice and the number of room: A3 B2 C1 Duration of…
Part C: Function, for and plotting We did a project in the lecture on calculating the free fall speeds and plotting them on a graph. This part is similar to the project. An engineer has derived a relationship between the force applied to a material and the extension in length that the force would cause. The relationship between force f and extension e is given by: You are asked to plot a graph showing the relationship between force and extension. You are asked to complete the following tasks: Task 1 Write a Python function which returns the value of e for a given input f. Do not use literals (e.g. 5.5, 10) in the expressions for e in the function. Instead you should define constants and use them. Note that the relationship between e and f depends on whether f is bigger than 10 or not, this means you need a certain Python construction in your function. If you can't think of that, have a look at Part A of Lab03.
A performance venue hosts many concerts a year. Performers perform several times a year for the concerts. Each concert has one or more performers and has a name and a specified seating arrangement. A concert is held in one (and only one) of several concert halls, each of which has a room number and the number of seats. Each concert generates revenues from the sales of tickets. Assume that the price of the ticket is the same for the same concert, but different prices for different concerts.Identify several attributes and a key field for each entity. Represent this situation of concerts and performers with an E-R diagram

Q1: Research Groups In response to popular demand, Dan’s established two research groups A and B composed of his n graduate students. Each of these students is a member of exactly one of the two groups at any given time. The students are numbered from 1 to n in some arbitrary order. To measure the success of his research groups, Dan assigns a citation score to each of them. Initially, both groups have citation score 0. Throughout the semester, events of the following two types happen: Student x publishes a paper in which they cite student y’s work (youcan assume all of the students have been around long enough to have prior research that can be cited). As a result, If x and y are in the same group, their group’s citation score increases by 1. If x and y are in different groups, y’s group’s citation score increases by 5. Dan changes student x’s group (from A to B or from B to A) to have them work on different projects. To assess the overall success of the research groups, Dan…
