Answer:
$7.50
Step-by-step explanation:
Since there is a 50% chance that the card is odd, the expected payoffs would be $15 * 50%=0.5*15=7.5. Hope this helps!
the point that the function intercepts the x axis are the zeros of the function, where the products set equal to zero give you the x coordinate in which it intercepts.
x=-15 and x=9
set both equal to 0
x+15 and x-9
These are your two products
(x+15)(x-9)
or
x^2+6x-135
The answer is 55.75! Trust me I took a test on this and its the right one.
Yes, it is 0.09 grater that 10.01
