Answer:
Step-by-step explanation:
The answer is C, or 28.
You can plug the values into a regression calculator to find the equation. When you do this, you will get the equation y=18.001+0.3ln(x). When you substitue 19 in for y, you get that x is about 28.
The lcm of 120 and 20 is 120!
20 = 2 x 2 x 5
120 = 2 x 2 x 2 x 3 x 5
LCM = 2 x 2 x 2 x 3 x 5
