Given:
μ = 2 min, population mean
σ = 0.5 min, population standard deviation
We want to find P(x>3).
Calculate the z-score
z= (x-μ)/σ = (3-2)/0.5 = 2
From standard tables, obtain
P(x ≤ 3) = P(z ≤ 2) = 0.9772
Therefore
P(x > 3) = P(z > 2) = 1 - 0.9772 = 0.0228
Answer: 0.02275
Answer: C) F(4) = 0
Detailed Explanation:
A zero/root of a polynomial is a value of the variable which makes the value of the polynomial to 0.
Therefore, when (x - 4) is a Factor :-
=> x - 4 = 0
=> x = 4
=> x = 4 is the Zero of the Polynomial.
Answer:
16 pi cubic units
Step-by-step explanation:
Given that a region is bounded by
And the region is rotated about x axis.
We can find that here radius would be y value and height would be dx
So volume would be as follows:
If f(x) is rotated about x axis volume
= 
cubic units.
They both cost 10 dollars
