Answer:
"Independent Variable: Use of calculators
Dependent Variable: How fast student worked math problem
Control: Group not using calculators
Constant: Same math problem"
Explanation:
Independent variable: In research, the term "independent variable" is described as a variable that is being changed by a researcher to see its effects on the dependent variable. Independent variable isn't changed by any variable a researcher is trying to evaluate or measure.
Dependent variable: It is being tested by the researcher, and tends to represent a specific quantity whose value is dependent on some manipulations i.e., any changes being made onto the independent variable will hamper the dependent variable directly.
Control group: It is composed of specific participants that don't receive the "experimental treatment". When a researcher is administering an experiment, these participants are being randomly assigned to the given group.
One reason is because of the geography of Greece, and probably the main reason is to stop any monarchies from forming and ruling them.
Answer:
Explanation:
13)
---- (1)
------ (2)
Multiply equation by 5 and equation 2 by 4
------ (3)
------ (4)
Subtract equation 3 from 4
Divide both sides by -12
Substitute in equation 1
Subtract 24 from both sides
Divide both sides by 4
----------------------------------------------
14)
---- (1)
----- (2)
Make x the subject of formula in (2)
Substitute in (1)
Open bracket
At this point, we conclude that thee system has no solution.
----------------------------------------------
15)
--- 1
----2
Substitute in (2)
Subtract 4 from both sides
Divide both sides by 8
Substitute in equation 1
----------------------------------------------
16)
Add both equations
Divide both sides by 0.8
Substitute in (1)
Subtract 2.5 from both sides
Divide both sides by 0.4
----------------------------------------------
17)
Substitute in (1)
At this point, we conclude that thee system has no solution.
Answer:
