Below are sample questions representative of the exercises included on this worksheet and related ALG2.238 Using Matrices for Real Contexts (Extension) skill assessments:

Problem 1Difficulty: Mastery

A three-state customer model uses column vectors with states Online, InStore, Inactive: T = [[0.70, 0.20, 0.10], [0.20, 0.70, 0.10], [0.10, 0.10, 0.80]]. Current vector is v = [500, 300, 200]^T. Which use and interpretation are correct?

Av T = [430, 330, 240]^T, predicting 430 Online, 330 InStore, and 240 Inactive customers next period

BT + v = [500.70, 300.70, 200.80]^T, predicting the next period

CT v = [430, 330, 240]^T, predicting 430 Online, 330 InStore, and 240 Inactive customers next period

DT v = [240, 330, 430]^T, predicting 240 Online, 330 InStore, and 430 Inactive customers next period

Solution & Explanation:With column vectors, multiply T by v. The outputs are Online: 350+60+20=430, InStore: 100+210+20=330, and Inactive: 50+30+160=240.

Problem 2Difficulty: Mastery

A resource matrix A has rows bread slices, cheese slices, and cups and columns sandwiches and smoothies. A combo matrix B has rows sandwiches and smoothies and columns Combo 1 and Combo 2. What does AB represent?

AResources needed per combo, with rows resources and columns combos

BCombos needed per resource, with rows combos and columns resources

CThe number of customers choosing each combo

DThe transition percentages from sandwiches to smoothies

Solution & Explanation:AB follows the chain combo to menu items to resources. The rows come from A, so they are resources, and the columns come from B, so they are combos.

Problem 3Difficulty: Mastery

A resource matrix R = [[3, 2], [1, 2], [4, 1]] has rows fabric, zippers, labor and columns jackets, bags. Plan matrix X = [[5, 3], [4, 8]] has columns Plan A and Plan B. In RX, what does the zippers row, Plan B column entry equal and mean?

A13, the number of zippers needed for Plan A

B19, the number of zippers needed for Plan B

C25, the amount of fabric needed for Plan B

D20, the labor hours needed for Plan B

Solution & Explanation:The zippers row is [1,2] and the Plan B column is [3,8]^T. The dot product is 1(3)+2(8)=19 zippers.
