Answer:
σ = 0.5102
Step-by-step explanation:
If
Y = volume filled,
µ = mean
It is a normal distribution
It follows that
0.95 = P (|Y − µ| < 1) = P (|Z| < 1 / σ)
so that
1 / σ = 1.96 ⇒ σ = (1 / 1.96)
⇒ σ = 0.5102.
A: 15/45 = 3/5 in simplest form.
The red line is y=1/2x -4 while the blue one is y=-2x+1. It's the last statement
Answer:
B
Step-by-step explanation:
multiply both sides by 2 to eliminate the fraction
- x > 12
multiply both sides by - 1
Remembering to reverse the inequality symbol as a consequence
x < - 12 ← reverse symbol
⇒ { x | x ∈ R, x < - 12 } → B
