Answer:
20
Step-by-step explanation:
cube everything in the ( )
2^3(x^4)^3
you get 8x^12
8 +12 =20
The data consists of 25 observations - this is just how many people were involved in the study. (count the rows, excluding the header)
As for number of variables, that depends on the aim of the study. More likely than not, I suspect the name of each person involved is irrelevant, which leaves 7 variables. (count the columns, excluding the first)
We can use y2-y1/x2-x1 to find the slope. Therefore, we have:
-5-(-13)/8-(-4). That gives us -5+13/8+4, or 8/12 = 2/3.
Hope this helps!
