A local bookstore is keeping a database of its customers to find out more about their spending habits and so that the store can start to make personal recommendations based on past purchases. The first 5 lines of the database appear in the accompanying table. Complete parts (a) and (b) below. a) What does a row correspond to in this data table? Choose the correct answer below. A. Each row represents a different customer. B. Each row represents a different transaction. C. Each row represents a different date. D. Each row represents a different book. How would you best describe its role? Choose the correct answer below A. As a respondent B. As an experiment C. As a case D. As a participant b) How many variables are measured on each row? (Type an integer or a decimal.)

Step 1
So, the correct answer is B. Each row represents a different transaction. The role of the data table in this scenario is to record and provide information about each transaction. So, it can be best described as a case. So, the correct answer is C. As a case. Show more…

The number of tickets of each class purchased for a particular flight is given by the vector N = [8, 21, 115]. What is the significance of P · N? 1.35 The inventory of computers at each outlet of a three-store chain is given by the matrix N = [9 12; 15 4; 7 0] where the rows pertain to the different stores and the columns denote the number of brand X and brand Y computers, respectively, in each store. The wholesale costs of these computers are given by the vector D = [700, 1200]^T. Calculate ND and state its significance.

The distribution system for the Herman Company consists of three plants, two warehouses, and four customers. Plant capacities and shipping costs per unit (in $) from each plant to each warehouse are as follows: Plant 1: Capacity = 100 units, Shipping costs to Warehouse 1 = $5, Shipping costs to Warehouse 2 = $7 Plant 2: Capacity = 150 units, Shipping costs to Warehouse 1 = $6, Shipping costs to Warehouse 2 = $8 Plant 3: Capacity = 200 units, Shipping costs to Warehouse 1 = $4, Shipping costs to Warehouse 2 = $6 Customer demand and shipping costs per unit (in $) from each warehouse to each customer are as follows: Warehouse 1: Customer 1 demand = 50 units, Shipping costs to Customer 1 = $10, Customer 2 demand = 75 units, Shipping costs to Customer 2 = $12 Warehouse 2: Customer 3 demand = 100 units, Shipping costs to Customer 3 = $8, Customer 4 demand = 125 units, Shipping costs to Customer 4 = $10 Choose the correct network representation of this problem.

The manager of a local hotel knows that on holiday weekends, if they charge $116 per room, they will book all 100 of the rooms in the hotel. For every $42 increase in price, they will book 6 fewer rooms. In the following parts, we will write an equation that represents the number of rooms rented as a function of the price charged per room. Part a) Identify the input and output to the function and the variables that you will use to represent them. Part b) Using the input and output from Part a), create a table that includes at least 5 different room charges and the corresponding number of rooms that are rented. Part c) Based on the table you created in Part b), what type of function does this table represent? How do you know? Part d) Using the above parts, write an equation that represents the number of rooms rented as a function of the price charged per room.
