Answer:
0.9209
Explanation:
For a normally distributed random variable, the only way to find areas is using the z score. The z score is given by the equation:
Where μ is the mean, σ is the standard deviation and x is the raw score to be measured.
The area under the standard normal curve that lies between the interval z=-2.73 and z=-1.39
From the z table, Area between -2.73 and -1.39 = P(z < -1.39) - P(z < -2.73) = 0.0823 - 0.0032 = 0.0791
Since the Area between -2.73 and -1.39 is 0.0791, the are outside the interval = 1 - 0.0791 = 0.9209
The number of molecules of NO₂ that can be obtained when 2 molecules of NO react is 2 molecules
<h3>Balanced equation</h3>
We'll begin by writing the balanced equation for the reaction. This is given below:
NO + O₂ —> NO₂
There are 3 atoms of O on the left side and 2 atoms on the right side. It can be balanced by writing 2 before NO and NO₂ as shown below
2NO + O₂ —> 2NO₂
Now, the equation is balanced
From the balanced equation above,
We can see that 2 molecules of NO will react to produce 2 molecules of NO₂.
Thus, we can conclude that 2 molecules of NO₂ will be obtained from the reaction.

Answer:
Hurricane Flash flood tsunami and tornado
Explanation:
What is a severe weather event?
A Severe weather event is 1-2 inches of hail (25-51 mm) an F1 tornado or winds up from 58-75 miles per hour (or 93 to 121 km/hour) but there is something called a Significant severe weather which is more than what is listed. So we already know that a hurricane, tornado, flash flood and tsunami are ALL severe weather events. But what about Earthquake and Volcano. While yes, they ARE considered severe events, they are NOT titled under these criteria.
