Answer with explanation:
⇒The given equation of line in two variable is :
y = 10 x + 15
If we have to find the solution of the equation of a unique line,as on a line there are infinite number of points lying on it.
So, Line, y=10 x + 15, has infinite number of solution.
Substituting different value of , x we will get different value of y,and by Substituting Different values of y, we will get different values of x.
→→If, x=k, then solution set of line, y=10 x + 15 ,will be,
(x,y)=All the points lying on the line, that is of the form,(k, 10 k +15).
Answer:
Standard deviation = 4
Step-by-step explanation:
Given the following data;
Mean = 25
Variance = 16
To find the standard deviation;
Mathematically, standard deviation is given by the formula;
Substituting into the formula, we have;
Standard deviation = 4
