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.
Answer:
B. x = 1/4y²
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
Also in this case we can use the Pythagorean theorem in this way
x^2 + (5√3)^2 = 10^2
x^2 + 75 = 100
x^2 = 25
x = +/- 5
we take only the positive value because a lenght can’t be negative
x = 5
