1. An Experimental

2. Dependent

3. Independent

The difference in cholesterol level is the DEPENDENT variable. This is because the difference in cholesterol level is what the researcher wants to determine.

The treatment with a drug or placebo is the INDEPENDENT variable. This is because this is what the researcher manipulates to determine the difference in cholesterol level which is the dependent variable in this experimental study.

The last one

for every 4 miles Vanessa jogged, Cody jogged 3 miles. if Vanessa jogged 1 mile, how far would Cody have jogged
Ksju [112]
Alright here's the breakdown:

it said every 4 miles <span>Vanessa jogged, Cody jogged 3 miles.

so

</span><span>Vanessa jogged 1 mile

that means 

Cody jogged .75 of a mile ( or 75% of 1 )

because

Cody will always jog 75% of  how much Vanessa joged 

so say that

</span><span>Vanessa jogged 50 miles

all you do is take 75% of how much </span>Vanessa jogged

and that should be how much Cody joged 

hopes this helps!
