Question:

A. Does the table represent a proportional relationship?
B. If the relationship is proportional, what is the constant of proportionality?
Total wight in pounds. 12 18 30 60
Number of books. 10 15 25 50

A. Yes the table represents a proportional relationshipB. The constant of proportionality is 1.2Step-by-step explanation:Two quantities are proportional if:One of them is equal to the constant times the other oneIf x and y are proportion, then y = k x, where k is constant∵ Total wight in pounds ⇒ 12 , 18 , 30 , 60∵ Number of books ⇒ 10 , 15 , 25 , 50- Divide each two corresponding data to check if all they give the same constant or not∵ 12 ÷ 10 = 1.2∵ 18 ÷ 15 = 1.2∵ 30 ÷ 25 = 1.2∵ 60 ÷ 50 = 1.2- That means the total wight is equal to constant times the number of books∴ Total wight = 1.2 Number of books∴ The total wight and the number of books are in a proportional relationshipA. Yes the table represents a proportional relationship∵ Total wight = 1.2 Number of books∴ The constant of proportionality = 1.2B. The constant of proportionality is 1.2Learn more:You can learn more about the proportionality in brainly.com/question/10708697#LearnwithBrainly
