Answer:
-7π/3 or -420 degrees
Step-by-step explanation:
So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.
The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.
π/2 - π/6
3π/6 - π/6 = 2π/6
π/3
Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3
Answer:
C) The expected value is -$40, so the man should not buy the warranty.
Step-by-step explanation:
The total cost to the man is expected to be the total of the amount he pays for the warranty and any amounts he gets because he has the warranty ...
-$100 +600×0.10 +0×0.90 = -$40
The expected value of the warranty is -$40. Based on that alone, the man should decide not to buy it.
