The first matrix represents inventory (how many there are) of four types of objects. The second matrix is a price matrix. The third matrix is the product of the first two matrices. Give an example of real inventory and real prices for which the product matrix makes sense. Describe where you found your prices. Complete the matrices using your values and explain the meaning of the product.

step-by-step explanation:

answer: i don't understand. what are the options

step-by-step explanation:

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
