Answer: Karen's weight = 125 pounds
Step-by-step explanation:
Let Karen's weight be x , this means that John's weight is 3x.
Two times John’s weight = 2(3x)
Two times John’s weight plus Karen’s weight is 875 pounds implies;
2(3x) + x = 875
6x + x = 875
7x = 875
divide through by 7
x = 125
Therefore Karen's weight = 125 pounds
John's weight = 3 x 125 = 375 pounds
Answer:
The dependent variable depends on the independent variable.
Step-by-step explanation:
- The variable whose values are deliberately changed by the researcher in order to obtain the desired outcome is called independent variable...
- The values of the independent variable can be changed as per requirement, by the researcher...
- Manipulation can be done in the values of independent variable, but the researcher observes the value of a dependent variable during an experiment.
- An independent variable is a presumed cause whereas dependent variable is a measured effect.
- In a simple linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable, which means y depends on x
