1) What is the purpose of the random assignment of treatments to subjects 1 poin in an experiment? * (A) To create roughly equivalent groups that are proportionately representative before treatments are administered. (B) To prevent certain groups in the population from being systematically excluded in the experiment. (C) To reduce bias in the selection of the subjects to be included in the experiment (D) To eliminate the need for blinding in an experiment.

Random assignment refers to the use of chance procedures in psychology experiments to ensure that each participant has the same opportunity to be assigned to any given group. Study participants are randomly assigned to different groups, such as the experimental group or treatment group.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
