Answer:
<u>The response variable is; reduction in the pain associated with sickle-cell disease.</u>
<u>Explanation:</u>
Note, a response variable (dependent variable) simply refers to resulting effect (either significant or insignificant effect) of the independent variable on the subjects of the experiment.
In other words, the effect of the drug hydroxyurea after the experiment would show whether it leads to or not lead to a reduction in the pain associated with sickle-cell disease.
Inconsistent system of equation consists of equations whose graphs do not intersect (they are parallel lines) and there is no solution.
Dependent system of equations consists of equations that are same (their graph is the same) but written in different form.
Let us analyze the equations:
5x+<span>10y+15z=60 (1)
</span>2x+4y+6z=60 (2)
<span>x+2y+3z=60 (3)
We can divide the first one by 5 </span><span>to obtain the same left side as in equation (3), and to see if they are dependent:
x+2y+3z=12
</span>which is not the same as <span>x+2y+3z=60.
</span>They are not dependent (they are independent).<span>
We can divide the second one by 2 to obtain the same left side as in equation (3), and to see if they are dependent:
</span><span>x+2y+3z=30 (2) divided by 2
which is not the same as </span><span>x+2y+3z=60. They are not dependent (they are independent).
The graphs of the three functions are parallel so, they are inconsistent.
Solution: inconsistent and independent

The answer is 1, because you have got lets say 1 1/2 chocolate (it means one and a half) then if you eat the 1/2 (the half) then you have got 1 chocolate left.
