Which word best describes the degree of overlap between the two data sets? moderate none low high two line plots with the same scale and interval, from zero to ten, with tick marks every one unit. the plots are stacked vertically for comparison. each plot has sixteen data values. values appear as x marks above the line. upper plot data values are one x mark above two, one x mark above three, one x mark above four, two x marks above five, four x marks above six, three x marks above seven, two x marks above eight, one x mark above nine, and one x mark above ten. lower plot data values are one x mark above 1, two x marks above two, three x marks above three, four x marks above four, two x marks above five, two x marks above six, one x mark above seven, and one x mark above eight.

answer: the first graph

step-by-step explanation:

"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).
