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:
8^-3 I think (i'm too lazy to simplify)
Step-by-step explanation:
3 - 9 * 2 ÷ 3 = ?
3 - 18 ÷ 3 = ?
3 - 6 = -3
8 to the power of -3
hmmmm i dont think im right tell me if im not
