Dena has a box with 7 blue marbles and 3 pink marbles. A marble is drawn and then placed back into the bag. What is the probability that both of the marbles are blue?

i think 1: 2

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

its very big question plz make it small
