Answer:
Step-by-step explanation:
There are 44 slots with numbers 0 , 00 , 1 ,2 ...42
Bet is placed for an odd number
Total odd numbers are = 1,3,...41 = 21
Total numbers = 44
a) Probability of winning=n(odd numbers)/total numbers
=
b) Actual odds against winning =
c) Pay off odds are 1:1.
So profit if we bet 14 dollars = 14 (0.9131) = 12.7833
d) If pay off is the same as 0.4773:0.5227=0.9131:1
Profit would be =
Answer:
5 amperes will produce the maximum power
Step-by-step explanation:
The power generated by an electrical circuit (in watts) as a function of its current c (in amperes) is modeled by: P(c)= -12c^2 + 120c.
To find out the maximum power we need to find the vertex
formula to find x -coordinate of vertex is
P(c)= -12c^2 + 120c is given in the form of y=ax^2+bx+c
a= -12, b = 120
c= 5 amperes will produce the maximum power
