Given: 2,500 shares of a stock bought for $8 a share
<span>Probabilities: the stock will rise to a value of $32 a share is 22%</span> <span> the stock will fall to $3 a share is 78%</span>
<span>Question: What is the expected value of the investor’s profit from buying the stock?</span>
Solution: (22%(32-8)-78%(8-3))2500
(.22(24)-.78(5))2500
(5.28-3.9)2500
(1.38)2500
3450
Answer:
2-sqrt14/2, 2+sqrt13/2.
Step-by-step explanation:
What you do is you have to do the quadratic equation like it says in the problem.
x= −b± sqrtb^2 −4ac
/2a
.
a=-2, b=4, c=5.
x=-4±sqrt(4)^2-4(-2)(5)/2(-2).
x=-4±sqrt16+40/-4.
x=-4±2sqrt14/-2.
2-sqrt14/2, 2+sqrt13/2. is your answer once you have done everything.
Answer:
44) 40%
46) 33.3%
68) 8%
74) 72 units
Step-by-step explanation:
44) 20/50= .2= 2-%
46) 5/15= .333= 33.3%
68) 24/300= .08= 8%
74) .8x90= 72
decimal can be made into percents multiplying by 100 (decimal point 2 spots to the right)
percent can be made in to decimals by dividing by 100 (decimal point 2 spots to the left)
Answer:
30*100/70= 42.85% chances that you will draw a Etruscan coin and same way 42.85-100= 57%
