_____ refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.

Setler79 [48]

Answer:

Internal validity

Step-by-step explanation:

Internal validity is a scientific study that emphasize on the fact that there is a proof to validate a specific study. Let's say i'm a forensics scientist for example; and there was a recent crime scene in some nearby sub-urban area which demands our call, when present at the scene, The main task there is to gather information as much as we can which is required to be investigate in the laboratory for further analysis.The process of information gathering is our independent variables which varies with different causes of the crime, the laboratory analysis that make deductions (which is cause by some manipulation) of the information gathered is our dependent variables.

Therefore, we can conclude that Internal validity refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.

How do you begin to solve x^3-3x^2 > x-3?

aliya0001 [1]

For any polynomial, first check to see if it factors. Then you can set each factor equal to zero.
$x^3 -3x^2 -x+3 \ \textgreater \ 0 \\ \\ x^2 (x-3) - (x-3) \ \textgreater \ 0 \\ \\ (x^2 -1)(x-3) \ \textgreater \ 0 \\ \\ (x-1)(x+1)(x-3) \ \textgreater \ 0$

The three zeros are -1,1,3

Next plug in values in each interval between zeros to test whether its greater than 0.

Try x values: -2,0,2,4

x = -2 yields a negative result, the interval x< -1 is Not a solution.

x = 0 yields a positive result, the interval -1
x = 2 yields a negative result, the interval 1
x = 4 yields a positive result, the interval x>3 IS a solution
