Answer:
D. The equation has a variable multiplied by itself. A squared variable.
Step-by-step explanation:
A quadratic equation will always start with a term being squared. For example, 
+ 5x + 7 = 44. Another example would be 
+ 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!
Answer:
B : -2
Step-by-step explanation:
Answer:
Independent variable- time spent in the dark room
Dependent variable - number of objects correctly identified
Conditions of the experiment- low light environment and lighted environments
Scores from the independent variable are used to construct the frequency distribution
Step-by-step explanation:
The independent variable is the factor that is being manipulated in an experiment and this time it is the time spent in a darkened room.
The dependent variable is the response variable, in this case, the number of objects correctly identified.
The experimental conditions involved bringing people from a lighted area into a darkened room.
