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.

Find the y intercept and slope
Naya [18.7K]
Okay so first off the equation of a line is
Y=mx+b
m= the slope
b= the y intercept

The Y intercept of this line is 2 and the slope is 5/3! You know this is the slope because if you start at point a and go up 5 and to the right 3, you end up at point b.

The equation for this line would be y=5/3x+2

Find the common difference for the sequence shown: [1/5, 13/40, 9/20...)
bazaltina [42]
<h3>Answer:  1/8</h3>

Explanation:

Pick any term and subtract off the previous term to get the common difference.

So,

13/40 - 1/5 = 13/40 - 8/40 = (13-8)/40 = 5/40 = 1/8

Or

9/20 - 13/40 = 18/40 - 13/40 = (18-13)/40 = 5/40 = 1/8

The positive common difference value indicates this arithmetic sequence is increasing.
