Answer:
Cold weather
Explanation:
The reason that Alec should limit his driving time/distance in all of the following areas or conditions except for cold weather is because of a concept called temperature inversion. Temperature inversion means that in winter season there is a warm layer of air trapped between two cold layers of air. This happens in winter as the air at altitude is always cold but now the surface temperature or air is also cold. Hence, the warm air above the surface and at lower altitude traps air pollutants contributing to smog occurrence. This is a natural phenomenon and therefore, Alec cannot reduce the chance that he will contribute to a major smog occurrence during cold weather by limiting his driving.
The correct answer is fulcrum
Explanation: Fulcrum is a point of balance. the closer the fulcrum is to the load, the easier the work will be.
Answer:
The response to the question is a discrete random variable.
Explanation:
By definition of a discrete random variable we infer that the response can only take certain known values but the response shall be completely random. As an example when we toss a fair coin the out comes are discrete as only either head or tail is possible and the outcome is random meaning we cannot predict the outcome before hand.
Similarly an continuous random variable takes any value in a set and there are infinitely many possible values it can take. For example if we choose any real number between 1 and 10. Since the answers are infinitely many in number and are completely random.
Now in our survey we can infer that the responses shall be either "yes I smoked last week" or "No i didn't smoke last week". Hence the variables are discrete and random.
<span>Watching the Bobo doll being pounded on TV by an adult has the same inference for a child or adult as if it were happening right in from of them because whether it is on a metal box or right in front of us, we are able to discern that the deed is actually happening. We can actually see it happening.</span>
