So 4x^2+-2x+-6 then multiply by 5 would be the Area of the entire rectangle using the formula A=bh
You'll get 4x^2 − 2x − 6
3 in by 4 in
because one half of 6 is three and one half of 8 is 4
X-4=2x+4
-X -X
-4=x+4
-4 -4
X=-8

Answer:
1.870828693387
Step-by-step explanation:
Standard Deviation, σ: 1.870828693387
Count, N:4
Sum, Σx: 12
Mean, μ: 3
Variance, σ2: 3.5
Steps
σ2 = Σ(xi - μ)2
N =
(6 - 3)2 + ... + (1 - 3)2
4 = 14
4 = 3.5
σ = √3.5
= 1.870828693387
