The first one is a. If you solve for x, equals 50. And if you retrace the steps described in a, describes the situation. Lost half, then one more.
The second is c, the inequality describes the condition and solves how many commissions he needs to earn at least 100 or more dollars a day.
Would it be 6.5 since the scale factor is 1.5 and its added to the 3 to get 4.5? correct me if i’m wrong

Answer:
0 = x⁴ -x³ -9x² -11x -4
Step-by-step explanation:
Each root r contributes a factor of (x-r). The factored form of the polynomial of interest is ...
0 = (x +1)³(x -4)
0 = (x³ +3x² +3x +1)(x -4)
0 = x⁴ -x³ -9x² -11x -4
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.
