I believe it is B, as C and D both are based on the number of books sold while the only variable to determine the amount of money she earns are the additional doors she knocks on.
Answer:
-4 to -1.5
Step-by-step explanation:
When the graph start to slope downwards or go down its decreasing. So when the hump starts to go down at (-4,0) it then starts to go up again after (-1.5,0). Hope this helps:)
Since 74% of the middle area is bounded, this means that
there is 13% on the left side, and another 13% on the right side.
P (left) = 0.13
P (right ) = 1 - 0.13 = 0.87
At this P values, the z scores are approximately:
z score (left) = -2.22
<span>z score (right) = 1.13</span>
80. there's no mathematical equations, also there's nothing to compare
