Answer:

Length: 11.95

Width: 9.95

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

To begin solving this question we need to create a formula to then solve. According to the information given in the question we can create 2 formulas.

$P = 2L+2W$

$L = 2+W$

<u>Where:</u>

P is the perimeter
L is the length
W is the width

Now we can replace L for the L in the P formula and solve for W, Like so....

$43.8 = 2(2+W)+2W$

$43.8 = 4+2W+2W$

$39.8 = 4W$

$9.95 = W$

Now that we have the value of W we can plug that into the L formula and find L

$L = 2+9.95$

$L = 11.95$

Finally, we can see that the value of the Length is 11.95 in and the Width is 9.95 in

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Answer:

Step-by-step explanation:

Hello!

A double-blind experiment is a type of experiment where both the experimental units and the researchers that analyze the data don't know what kind of treatment was applied to each subject.

This means, that if it is a placebo-controlled experiment. The subjects will be randomly assigned either the medicament to test ("treatment" group) or the placebo ( "control" group) but they will not know which one they are taking. This way the placebo effect is eliminated.

On the other hand, in other to eliminate the observer bias, the researchers will also not know which patient belongs to the "control" group and wich patient belongs to the "treatment" group.

I hope it helps!
