(-4b - 8) = 20
-4b = 20 + 8
-4b = 28
b = -7
Answer:
c = 7 (if you have more questions like this in the future, use photomath (an app) or mathpapa algebra calculator (a website))
Because the choices concern more about the median, the median of Data set A is equal to 17. The median of Data set B is 16. Thus, the median for A is not exactly similar to the median of B.
The range of Data Set A is 8 while that of Data Set B is 7. Thus, the range of A is greater compared to B.
