The number of wins for a high school football team is measured for the season. when the team plays at home, it is generally believed that they will win. comparing the location of the game and the number of wins, a correlation coefficient of −0.91 is calculated. what would this imply about the football team winning at home?
a. the scatter plot would closely resemble a straight line with a negative slope. the data has a strong negative correlation, and a causal relationship exists between the team playing at home and winning.
b. the scatter plot would closely resemble a straight line with a negative slope. the data has a strong, negative correlation, but causation cannot be determined.
c. the scatter plot would not represented by a line of best fit with a negative slope. there is a weak correlation between the football team playing at home and winning.
d. there is no causation and almost no correlation between the football team playing at home and winning.

"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).

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

positive

step-by-step explanation:

the quadrant is facing upwards
