Answer:
48 rocks
Step-by-step explanation:
there are 4 rocks in one pound since each rock weighs 4 ounces so 4 times 12 equals 48

Step-by-step explanation:
<u>Linear Modeling</u>
It consist is setting up a linear relationship between two variables, given some experimental data. Only 2 points are needed to set up the equation of a line, but if more than 2 points are used, then the result should use statistical approaches like linear regression to find the best-fit line.
For the question at hand, Marty practices his piano lessons 11 minutes the week #1. It provides the first point (1,11). He practices 25 minutes per day on the third week. It gives us another point (3,25). This is enough to find the equation of a line. The general formula for a line, having two points (m1,w1) (m2,w2) is

Let's plug in our values

Simplifying:


1/2 x 2/3 x 3/4 = 1/4
(Sorry, I did the math wrong. I meant 1/4)
W = 7/15 L
w = 56
56 = 7/15 L
56 x 15/7 = 7/15 x7 L
L = 120
