festyles. They studied disc replacement and spinal fusion. Identify the response and explanatory variables. (4 points) Group of answer choices
A.)The response variable is the amount of activity the patients were able to do after surgery, and the explanatory variable is the type of spinal surgery.
B.)The response variable is the type of spinal surgery, and the explanatory variable is the amount of activity the patients were able to do after surgery.
C.)The response variable is disc replacement, and the explanatory variable is spinal fusion.
D.) The response variable is spinal fusion, and the explanatory variable is the amount of activity the patients were able to do after surgery.
E.) The response variable is spinal fusion, and the explanatory variable is disc replacement.
Answer: A.)The response variable is the amount of activity the patients were able to do after surgery, and the explanatory variable is the type of spinal surgery.
Step-by-step explanation:
The response variable focuses on the question in a study or an experiment while the explanatory variable is the one which explains the changes in that variable.
Here response variable is the amount of activity the patients were able to do after surgery while the explanatory variable will be spinal surgery type
If the answer can be left in a fraction than this is the solution: 2×5/8=5/4 5/4-1/3=11/12 if you mean the answer must be left in a whole number than.. I don't really know how to do it
The correct answer is) D. Because on the graph you can see that it increases by 25 each day which follows the equation Y=25x
The reason for this is because she reads 25 pages a night Meaning that the total number of pages Jacqueline has read (Variable Y) = 25 pages a night (x)
