The number of men and women receiving bachelor's degrees each year has been steadily increasing. For the years 1970 through the projection of 2014, the number of men receiving degrees (in thousands) is given by the equation y equals 3.8 x plus 441, and for women, the equation is y equals 14.4 x plus 311, where x is the number of years after 1970.

Step-by-step explanation:

Given:

The number of men receiving degrees (in thousands)

y = 3.8x + 441

The number of women receiving degrees (in thousands)

y = 14.4x + 311

y = 14.4x + 311

y = 3.8x + 441

Solving the above equations simultaneously,

3.8x + 441 = 14.4x + 311

10.6x = 130

x = 12.24

Inputting the value of x into the initial equation to find y,

y = 3.8(12.26) + 441

= 487.6

Therefore, the point (12.26 , 487.6) will be the solution of our given equations.

"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).
