Answer:
1.) 4
2.) -11
3.) -4
4. 19
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
let y1= 2, y2=3, x1=-1, x2=-4
(3-2)/(-4-(-1))=
1/-3
Answer:
It would be this one
Step-by-step explanation:
Answer:
The formulas are functionally the same, but 'n' (the sample size) is used instead of 'N' (the population size).
Step-by-step explanation:
The sample mean is the average value for a set of observations which is derived from a population. While the population mean is the average value for the entire set of observation belonging to a particular study of interest.
The set of observation belonging to a population is denoted by 'N' ; while the sample size is denoted as 'n' :
The mean formula is written thus :
Population mean = Σx / N
Sample mean = Σx / n
Where, x = set of values.
