While a(n) manipulates an independent variable in order to see the change in a dependent variable, a(n) typically uses the same structure but with an independent variable that cannot truly be manipulated by the experimenter. Even though the independent variable cannot be truly manipulated, this type of research can be done by having the participants experience all levels of the independent variable () or by having each participant experience only one level of the independent variable ().

step-by-step explanation:

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
