Answer:
So both equations are true
Step-by-step explanation:
#4 was asking you to substitute x = 4 into both equations to see if it's the solution of the equations.
Substitute x = 4
Ritz equation
y = 30x + 20
y = 30(4) + 20
y = 120 + 20
y = 140
Smits equation:
y = 15x + 80
y = 15(4) + 80
y = 60 + 80
y = 140
Both companies charged same price $140 for 4 days
So both equations are true
Answer: Conjugates
Step-by-step explanation:
Answer:
1) The dependent variable is;
The recorded exam scores of the student
2) The independent variable items in the experiment are;
a) The method of study;
i) Through visual information only
ii) Using auditory information only
iii) Not studying at all
b) The duration of study
Four days
c) The number of questions in the exam
100-questions
Step-by-step explanation:
Dependent Variable
The dependent variable is the measured result of the experiment which are the values that change due to a change in the treatment applied in the experiment
The dependent variable is the output of the function of the experiment from an varied inputs to the experiment which is the independent variable
Independent Variable
The independent variable are the variable taken as the cause of the desired effect which is observed measured as the dependent variable
