Answer: Hello mate!
You have one $20 bill, two $10 bills, three $5 bills and four $1 bills in a bag.
This adds to a total of 10 bills in the bag, and you want to know the expected value if you took one at random.
The expected value is defined as ∑pₙxₙ
where pₙ is the probability for each event (in this case is the number of bills of a given price divided the number of bills in the bag) and xₙ is the value of the bill.
Then we can write the expected value as:
E = (1/10)*$20 + (2/10)*$10 + (3/10)*$5 + (4/10)*$1 = (1/10)( 20$ + 2*$10 + 3*$5 + 4*$1) = (1/10)*($59) = $5.90
The expected value is $5.90.
Answer: False according to apex
Step-by-step explanation:
Let x be the amount invested at 6%
840 = 0.06x + 0.075(2x)
840 = 0.06x + 0.15x
840 = 0.21x
x = 840/0.21
x = 4000
Therefore, she invests $4000 at 6% and $8000 at 7.5%
