Answer: 50%
Step-by-step explanation:
Add 25% to 25% : do this because 1/4+1/4=2/4, which is a half. If you add 25% to 25%, you get 50%, and 50% is also 1/2.
Answer:
B
Step-by-step explanation:
The expected value of profit margin is the sum of the product of profit margin and probability.
Wrench A:
... 10×.05 +20×.6 +30×.2 +40×.15 = 0.5 +12 +6 +6 = 24.5
Wrench B:
... (20+40)×.3 +(30+50)×.2 = 18 +16 = 34
Wrench C:
... 15×.4 +30×.5 +(45+60)×.05 = 6 +15 +5.25 = 26.25
Wrench D:
... 5×.2 +10×.4 +15×.15 +20×.25 = 1 +4 +2.25 +5 = 12.25
___
Clearly, Wrench B has the greatest expected profit margin. That would be the one Jose should order if he's trying to maximize his profit.
If we presume north is along the positive y-axis, then Rachel's initial position is
.. (x, y) = (-√2, √2)
This does not match any of the offered choices.
If Rachel starts 2 mi NE of her house, then selection D is appropriate.
