Write an inequality to describe all the points on the coordinate plane above y=-4?

Answer: y > -4

Step-by-step explanation: i believe this is your answer because i think you are asking for the range more or less. when you do this, you have to just ask yourself what points would be acceptable (any y point above -4) so the answer would be any y value more than -4, y > -4

Expected is the sum of the payouts of each bet multiplied by its likelihood:

$EV= \frac{64*0.40+25*1.15+1*9.00}{90}\\EV= 0.70$
