Answer:
C) a positive correlation
Step-by-step explanation:
<em>More people ⇒ Longer time</em> is a positive correlation between those variables. However, <em>longer time</em> is not the desired outcome.
Rather, <em>shorter time</em> is the desired outcome. The correlation between <em>more people</em> and <em>shorter time</em> is negative. In order to compute that correlation numerically, one would have to define a function that would give a numerical value for "shorter time" that would model the goodness of outcome as time gets shorter.
So what we do is we first get the x on the right side: 7x-x = 6x.
Now we get the 5 to the left side: 71-5= 66.
Now our equation is 66=6x.
We divide 66 by 6 which makes x=11
