The answer is J. 2.0. This is because when you substitute in N = 2, you get (4.2 × 2)/1.2 = 8.4/1.2 = 7, and 7 is an integer.
I hope this helps!
Answer:
For a level of 0.0174 or more of nitrogen oxide, the probability of fleet is 0.01.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 0.02 g/mi
Standard Deviation, σ = 0.01 g/mi
Sample size, n = 81
We are given that the distribution of level of nitrogen oxides is a bell shaped distribution that is a normal distribution.
Standard error due to sampling:

Formula:
We have to find the value of x such that the probability is 0.01
P(X > x)
Calculation the value from standard normal z table, we have,
For a level of 0.0174 or more of nitrogen oxide, the probability of fleet is 0.01.

Answer:
C/2pi = r
Step-by-step explanation:
C = 2 pi r
divide with 2 pi on both sides to solve for r
C/2pi = r
