<span>Expected value is the sum of the probability of each even times the outcome of the event.
So she wins $10 with probability 2/8, $3 with probability 1/8, $0 with probability 3/8, and loses $3 with probability 2/8.
So,
E = 10(2/8) + 3(1/8) + 0(3/8) - 3(2/8)
=5/4 + 3/8 - 3/4
=7/4

Answer:
The value of u are,
0.93, -12.93
Step-by-step explanation:
It is given an expression in variable u
(u + 6² + 4 = 52
<u>To find the solution of given expression</u>
(u + 6)·² + 4 = 52
(u + 6)² = 52 - 4
(u + 6)² = 48
u + 6 = √48
u + 6 = ±6.93
u = ±6.93 - 6
u = 6.93 - 6 or u = -6.93 - 6
u = 0.93 or u = -12.93
Answer:
idk its hard to me too
Step-by-step explanation:
It will be graph C. y=-2x+6
ratio of voljumes = 3^3 : 4^3 or 27:64
small/large = 27 / 64
vol of smaller = 27 * 320 / 64
=135
