Answer:
Expected return for this bet = - $0.0243
Step-by-step explanation:
to find out
the expected return for this bet
solution
we know that Number of slots in the spinner is
Number of slots in the spinner = 0 + 40 = 41 slots
so
P for you winning is here = 
and
Winning amount is = $40
so we can say that
Expected return for this bet is = Winning amount × P (winning) - Cost of bet ...............................1
put here value we get
Expected return for this bet = $40 ×
- 1
Expected return for this bet = - $0.0243
Answer: 245-83+103= 265 so it would be negtive 265
Step-by-step explanation:
Answer:-3
Step-by-step explanation:
First find g(3).
So g(3)= -2(3)+1 so g(3)= -5
now plug this value into f(x).
f(-5)= (-5)3 +4(3) = -15+12 = -3
To solve for P(QIR) we use the formula:
P(QIR)=[P(Q∩R)]/P(R)
But from the diagram:
P(Q∩R)=3/22
P(R)=7/22
hence
P(QIR)=3/22÷7/22=3/7
Answer: the answer is C. 80°
Step-by-step explanation:
= 360 - 110 - 90
=160°
b=1/2 (160)
