Answer:
One possible confound for the experiment is the attitude of the research assistants.
Step-by-step explanation:
A confounder simply means a variable that has impact in influencing both the dependent variable and independent variable, causing a spurious association.
So, we can conclude that the attitudes of the research assistants have positive and negative impacts in determining the reactions of both participants in the experiment.
The rudeness of a research assistant will negatively impact the response of the participant allocated to him/her.
The calmness of the other research assistant will positively impact the response of the participant allocated to him/her.
Answer:
the third one should be it
Answer:
Multiply both sides by 2:
Divide both sides by 4:
Multiply both sides by 5:
Answer:
The percentage of the change from 6 to 3 is a 50% decrease.
Step-by-step explanation:
Given the number '6'.
If the number changes from '6' to '3', means the number reduces to half.
as 6/2 = 3
Thus,
6 → 100%
and when reduces to half
3 → 50%
Thus, the percentage of the change from 6 to 3 is a 50% decrease.
ANOTHER METHOD
% Decrease = (original value - new value) / original value × 100%
= (6 - 3) / 6 × 100%
= 3/6 × 100%
= 0.5 × 100%
= 50%
Thus, the percentage of the change from 6 to 3 is a 50% decrease.
Answer:
x = -9
Step-by-step explanation:
The top angle would be 90 degrees due to the square.
The angles of a triangle add up to 180 degrees.
Set up the equation:
90 + 45 + x + 54 = 180
189 + x = 180
Subtract 189 from both sides:
x = -9
Now, if you need to solve for the angle, just plug x in:
-9 + 54 = 45 degrees
(In your case it is just looking for x so it would be x = -9)
