The level of nitrogen oxides (NOX) in the exhaust after 50,000 miles or fewer of driving of cars of a particular model varies No
Greeley [361]

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:

=\dfrac{\sigma}{\sqrt{n}} = \dfrac{0.01}{\sqrt{81}} = 0.0011

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.01

P(X > x)  

P( X > x) = P( z > \displaystyle\frac{x - 0.02}{0.0011})=0.01  

= 1 -P( z \leq \displaystyle\frac{x - 0.02}{0.0011})=0.01  

=P( z \leq \displaystyle\frac{x - 0.02}{0.0011})=0.99  

Calculation the value from standard normal z table, we have,  

\displaystyle\frac{x - 0.02}{0.0011} = -2.326\\\\x = 0.0174

For a level of 0.0174 or more of nitrogen oxide, the probability of fleet is 0.01.

The fraction 6/11 = the fraction 18/
kramer
The fraction 6/11 is equivalent to the fraction of 18/33. They both have the same value. Simply multiply both the numerator and denominator by 3 to the fraction of 6/11 to get the new equivalent one.

Please graph! 90 points! And BRAINLIEST
daser333 [38]

The points on the graph are:

  • Midline point = (0,-5)
  • Maximum point = (0.65,-2)

<h3>(a) The graph of the function</h3>

The equation of the function is given as:

f(x) = 3\sin(12x) - 5

See attachment for the graph of the function f(x)

<h3>(b) The midline point</h3>

This is the point that is on the line that passes through the midsegment of the function.

From the graph, a point on the midline is (0,-5)

<h3>(c) The maximum point</h3>

This is the point that is on the vertex of the function.

From the graph, a point on the midline is (5pi/24,-2)

This can be rewritten as: (0.65,-2)
