no it's you know for getting them for this
“Guides protect the park and make sure that the land and animals remain safe,” is the sentence Maria should use. It helps to explain what guides are for.
Answer:
He could have shut off the power first and de-energize the circuits in order to prevent being electrocuted.
Explanation:
Electrical Safety is very important, <em>especially for those working in such hazardous situations. </em>Almost all our things in the society are electrically-operated, thus it even becomes relevant to have an idea on how we can prevent from obtaining an electrical shock or burns due to faulty electrical tools.
In the worker's scenario above, it is clear that he did not shut off the power at the circuit breaker panel. This is the most important thing that one must include in his plan when attempting to correct an electrical problem. You must find where the electrical switch, fuses and circuit breakers are at first. Once you find their location, you have to turn them off (even if the circuits are of low-voltage).<u> In order to make sure that they are really turned off, test the circuits first. This will help you ensure that they are, indeed, de-energized.</u>
I just use regular ones cause I don’t like to reuse :)
The probability that the the sample mean would be less than x=132.25 will be calculated as follows:
z=(x-σ)/μ
μ- mean
σ- standard deviation
z=(132.25-138)/28=-0.2054
thus:
P(X≤x)=0.4207=42.07%
