Answer:
okay I'll try to answer it
9514 1404 393
Answer:
The (piece, perceived values) are ...
- Cindy, (3, 48%)
- Jamal, (1, 39%)
- Monique, (2, 33%)
Step-by-step explanation:
We assume the values and questions are as shown in the attachment.
1. After the division, Cindy bids only on piece 3, and Jamal bids only on piece 1. Hence the appropriate final division is ...
Cindy: piece 3
Jamal: piece 1
Monique: piece 2
__
2. Monique divides the land so that the value of each piece to her is 33 1/3%. That is her perceived value for the piece she gets.
The discriminant of
ax^2+b+c=0 is
b^2-4ac
when the discriminant is
less than 0, then there are no real roots
equal to 0, then there is 1 real root
greater than 0, then there are 2 real roots
so
2x^2-5x+7=0
a=2
b=-5
c=7
discriminat=(-5)^2-4(2)(7)=25-28=-3
-3<0
no real roots
