This question is a perfect example of the difference between false positives and false negatives. This hypothetical test is for all practical purposes, useless. Let's assume that the disorder is relatively rare and that only 1 out of a 1000 people have it and that we'll give that test to 20,000 people. Among that population, there will be:
1 person with the disorder who wasn't detected (false negative).
19 people with the disorder who were detected (true positive).
999 people without the disorder who were detected (false positive).
<span>
<span>18981 people without the disorder who were declared clean (true negative).
</span></span>
So we have a population of 1018 people who tested positive for the disorder, yet of that population, less than 2% of them actually have the disorder.
<span>The tokens act as secondary reinforcers. A secondary reinforcer is one that is associated with a primary reinforcer. In order for the reinforcer to achieve its objective, the person has to learn the association between the primary and the secondary reinforcer. For example, money is a secondary reinforcer, food is a primary reinforcer. When we see the money we are motivated by the association we make; <span>buy food with the money.
I hope my answer can help you.

Best answer is C) Observe how others dress.
SInce the dress code is unwritten, you won't find it in the company handbook or the website. Dressing how you want is a very "millennial" thing to do, but it might not score you any points at the office. The safest bet is to observe how others dress to get an idea of the expectations.
Headlights improve a driver's ability to identify hazards and conditions in the driving environment and even act as a warning to fellow drivers in certain situations.
A headlight is a lamp that is mounted on the front of a car to light the way. Although headlights and headlamps are frequently used interchangeably, in the most formal sense, headlight refers to the gadget's beam of light and headlamp to the device itself. Make sure you can stop in the area where your headlights illuminate. According to the legislation, you are required to turn on your headlights 30 minutes after dusk and keep them on until 30 minutes before dawn. Anytime you can't see at least 1000 feet in front of you, you must switch on your lights.
