Suppose there are 5 students in a room. The mean age is 20.2 20.2 years, and the median age is 19 19. If the youngest person leaves and is not replaced by another person, what happens to the mean and the median?

Step-by-step explanation:

If the youngest person leaves and is not replaced by another person, it means the mean age is no longer be 20.2 and the median is no longer is 19.

There are 4 students left, so

Mean: will inscrease, when number of terms descrease (only 4)

Media: will descrease, when we have to calculate the average value for term number 2 and 3, not only term number 3 before the youngest person leaves.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
