Answer: 1.5923926292577
Step-by-step explanation: Count, N: 14
Sum, Σx: 49
Mean, μ: 3.5
Variance, σ2: 2.5357142857143
Steps
σ2 =
Σ(xi - μ)2
N
=
(1 - 3.5)2 + ... + (6 - 3.5)2
14
=
35.5
14
= 2.5357142857143
σ = √2.5357142857143
= 1.5923926292577
Answer: E

took a test :)
Answer:
B & C
Step-by-step explanation:
since (2x - 5)(x - 4) = 0
to solve, it would be
(2x -5) = 0 or (x -4) = 0
I think the answer is a I might be incorrect
