Find the expected value of the winnings
marishachu [46]

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

Given F(x)= 3x-1 and g(x) = 2x-3, for which value of x does g(x) = f(2)?
emmasim [6.3K]

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

PLEASE Answer asap!!!!
Zina [86]

Answer:

x=0

Step-by-step explanation:

The axis of symmetry: x=\frac{-b}{2a} when the equation is y=ax^2+bx+c

The given equation is:

y=x^2-6

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

y=1x^2+0-6

Now, we can tell that a=1 and b=0. Plug these into the equation x=\frac{-b}{2a} :

x=\frac{-(0)}{2(1)}\\x=0

Therefore, the equation for the axis of symmetry for the parabola is x=0.

I hope this helps!
