Question

What is the constant of proportionality between the number of selfies (x) and the amount of data storage in megabytes (y) for the first pair of data (4, 8)?

A) 2
B) 4
C) 0.5
D) -2

Answer 1

The constant of proportionality between the number of selfies (x) and the amount of data storage in megabytes (y) for the first pair of data (4, 8) is 2 (option A). This is found by dividing y by x.

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities. In this case, we are looking for the constant of proportionality between the number of selfies (x) and the amount of data storage in megabytes (y) based on the first pair of data (4, 8). To find this, we would use the formula y = kx where k is the constant of proportionality. We can then solve for k by dividing y by x:

k = y/x = 8/4 = 2.

Thus, the constant of proportionality between the number of selfies and the amount of data storage in this instance is 2, which corresponds to option A).
