Answer:
16
Step-by-step explanation:
(1) Get the mean: (2 + 13 + 4 + 10 + 6) / 5 = 7
(2) Variance Formula: Σ(x-mean)^2)/N
-> <u>(2-7)^2 + (13-7)^2 + (4-7)^2 + (10-7) ^2 + (6-7)^2</u>
5
= 16
Answer:
Where is the figure?
Step-by-step explanation:
Answer:
2x+ 2y = -2
Step-by-step explanation:
Given the equation of a line as x + y = -1
To get the equation of the line P so the set of equations has infinitely many solutions, we will have to multiply the given equation by a factor
Multiplying the given equation by a factor of 2;
Given x + y = -1
Multiplying both sides by 2;
2(x + y) = 2(-1)
2x+ 2y = -2
Hence the required equation is 2x+ 2y = -2
