Answer:
The expected value is $4.35
Step-by-step explanation:
For us to calculate the expected value , we need to multiply each of the given probability by the individual payout value and add
So we have it as;
0.35(1) + 2(0.2) + 5(0.1) + 8(0.2) + 10(0.15)
= 0.35 + 0.4 + 0.5 + 1.6 + 1.5
= $4.35
Answer:
x = 4
Step-by-step explanation:
f(x)= 3x-1
f(2)= (3×2)-1
f(2)= 6 - 1
f(2)= 5
Now,
g(x) = f(2)
2x-3 = 5
2x = 8
x = 4
Answer:
x=0
Step-by-step explanation:
The axis of symmetry:
when the equation is 
The given equation is:

To make the a and b values more easily identifiable, we can rewrite it like this:

Now, we can tell that a=1 and b=0. Plug these into the equation
:

Therefore, the equation for the axis of symmetry for the parabola is x=0.
I hope this helps!
