Answer:
3.9
Step-by-step explanation:
Given the data:
Payout ($) (x) : 0 2 4 8 10
Probability p(x) : 0.35 0.2 0.1 0.2 0.15
The expected winning ; E(X) = Σ(x * p(x))
Σ(x * p(x)) = (0*0.35)+(2*0.2)+(4*0.1)+(8*0.2)+(10*0.15)
= 0 + 0.4 + 0.4 + 1.6 + 1.5
= 3.9
Draw the figure out and you will find that AB + BC = AC. Given this, put the equations together to form x+41+x+10=22. Solve to get x=-29/2
Answer: H
Step-by-step explanation:
So this is called a problem you would use PEMDAS or (please-excuse-my-dear-aunt-sally)
Parenthesis
Exponents
Multiply
Divide
Addition
Subtract
In this sens, since parenthesis are present you do them first so it would be H
Step-by-step explanation:
1a. Just add both of them.
1b. We just subtract both of the functions.
1c.
1d.
