Answer:
The beginning development of a star is marked by a supernova explosion, with the gases present in the nebula being forced to scatter. As the star shrinks, radiation of the surface increases and create pressure on the outside shell to push it away and forming a planetary nebula or white dwarf. 5.0. 3 votes.
Answer:
Explanation:
To find the percentage of cars averaged less than 62 mph calculate the corresponding z-score and use a standard normal cumulative probability table
<u>1. Z-score</u>
![Z-score=\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=Z-score%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
- x is the specific value of the random variable: 62mph
- μ is the mean of the population: 65mph
- σ is the standard deviation of the population: 5mph
Substitute and calculate
![Z-score=\dfrac{62-65}{5}=-0.600](https://tex.z-dn.net/?f=Z-score%3D%5Cdfrac%7B62-65%7D%7B5%7D%3D-0.600)
<u>2. Use of the table.</u>
The percentage of cars that averaged less than 62mph is given by the area under the curve to the left of z = -0.600.
From a standard normal cumulative probability table, the probability of z being less than -0.600 (which is equal to the probability of z being greater than 0.600) is 0.2743, which is 27.43%.
Thus, the conclusion is that 27.43% of the cars averaged less than 62mph.
All of the following are effective countermeasures of fatigue except: D. Allowing your eyes to lose focus.
<h3>What is a countermeasure?</h3>
This is the term that helps to describe something that helps a person to fight against another thing. The counter measure is usually what is taken in order to prevent something from happening or occurring.
Here fatigue has to do with the fact that a person is tired, worn out and they need to rest well in order to continue functioning properly in the chores or the tasks that they are known to indulge in.
When a person is tired they would have issues with their eyes enabling them to focus on what they are doing.
