Answer:
The answer is 24:42
Step-by-step explanation:
All you have to do is multiply 7 by 6 because for every red marbles there are 6 marbles.
Hopes this helps!!
I think it’s 74 bc I got it right but your might be different
Expected value of the bet is
the sum of the products of value of outcome and its probability,
less the amount paid to place the bet.
Outcomes value probability
win 225 1/4
lose 0 3/4
cost of bet = 40
So expected value of bet
E[X]=225*(1/4)+0*(3/4)-40
=56.25-40
=16.25
This means that in the long run, gambler will win, since the expected value is positive. (does NOT mean she will win in the next bet!)
Given:
The function is:
To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,
Step 1: Substitute 
.
Step 2: Interchange x and y.
Step 3: Isolate variable y.
Step 4: Substitute 
.
Therefore, the inverse of the given function is 
and the graphs of these functions are shown below.
