Answer: Randomized design.

Step-by-step explanation:

Randomization is the process of assigning the treatments or tested factors to the experimental units in an experiment in accordance to definite laws or probability is technically known as randomization.

A randomized design relies on randomization to control for the effects of extraneous variables.

In a randomized design, objects or subjects are assigned to groups completely at random. One standard method for assigning subjects to treatment groups is labelling each subject and afterwards, using a list of random numbers to select from the labelled subjects. It is used when the experiment has treatment conditions and subjects. Also, subjects are randomly assigned to different treatments.

How do you solve t=1/8sv and solve for v?
Kruka [31]

Answer:

v = (8t)/s

Step-by-step explanation:

Divide both sides by 1/8, so multiply both sides by 8.

8t = sv

Divide both sides by s.

(8t)/s = v

Switch sides.

v = (8t)/s

How to do geometry proofs I believe it's the subtraction property
notsponge [240]
Hi there!
You need to prove that line segment DE ≅ GH.

You're given:
Line segment DJ ≅ line segment GJ;
E is the midpoint of line segment DF;
H is the midpoint of line segment GJ.

You can justify that line segment DE ≅ line segment GH with the midpoint definition, which is a point on a line segment that divides it into two equal parts. The two equal parts in this case are line segments DE and GH, so DE ≅ GH.
