Answer:
a) - $0.169
b) - $0.04242
Step-by-step explanation:
Data provided in the question:
Bet amount = $4
Probability of losing $4 = 
Probability of gaining $4 = 
a) The expected value
= Winning amount × winning probability - Losing amount × Losing probability
= $4 ×
- $4 × 
= $4 × 
= - $0.169 (Negative sign means loss)
b) The amount lost for each dollar =
=
= - $0.04242
C.21 ft x 48 ft
because you multiply 7 by 3 and 12 by 3 and that is what it is
It helps immensely if you know your times tables.
a) 36 = 6*6 = 2*3*2*3 = 2^2*3^2
b) 45 = 5*9 = 5*3*3 = 3^2*5
c) 2 is not a common factor; 3^2 is a common factor; 5 is not a common factor. The greatest common factor is 3^2 = 9.
d) The least common multiple can be found a couple of ways.
.. 1) the product of the distinct factors to their highest powers
.. .. .. 2^2 * 3^2 * 5 = 180
.. 2) the product of the numbers divided by their greatest common factor.
.. .. .. 36 * 45 / 9 = 180
Answer:
3/2 or 1 and 1/2 and it already has a common denominator.
Step-by-step explanation:
The Denominators are the same and 4-1=3 with the same denominator.
