A year-long fitness center study sought to predict the amount of muscle mass gained (kilograms) based on the weekly time spent working out under the guidance of a trainer (minutes.) The slope of the regression line for the study was 0.12 and the y-intercept was 2.04.
For each additional minute (weekly) spent working out, the average muscle mass changed by:

A) 14.40 kg
B) 750.84 kg
C) 16.44 kg
D) 18.48 kg
E) None of the above

E. None of the Above

Step-by-step explanation:

The slope of the regression line for the study, m= 0.12

The y-intercept , c= 2.04.

Using the Slope- Intercept form of the Equation of a line: y=mx+c

The line is:

y=0.12x+2.04

For every additional minute x, the average muscle mass changed by 0.12kg, the Slope of the line.

CHECK

y(1)=0.12(1)+2.04=2.16kg

y(2)=0.12(2)+2.04=2.28kg

Change: y(2)-y(1)= 2.28-2.16=0.12kg

step-by-step explanation:

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
