Features of the experiment that inadvertently lead participants to respond in a particular manner is a definition of 1) experimenter bias 2) role attitude cues. 3) volunteer bias. 4) demand characteristics.

4. Demand characteristics.

Step-by-step explanation:

Demand characteristics refer to the situation where the subject of study change their behaviour according to what they think the experiment is about.

On the other hand experimenter bias, happens when the expertise of the experiment conducts the subject of the study indirectly. Volunteer bias, is thought to happen when there are volunteers on a study, who might have a different behaviour to the entire target group.

step-by-step explanation:

15   3/4 / 3 = 5   1/4

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
