Answer:
Step-by-step explanation:
Expected value of the bet =
<h3>
P(you make the correct draw) * 40 + P(you do not make the correct draw) * (-10) = </h3>
(4/52)(4/51)(4/50) * 40 + (1 - (4/52)(4/51)(4/50)) * (-10) =
(64/132600) * 40 + (1 - 64/132600) *(-10) =
64/3315 + (132536/132600) * (-10) =
64/3315 - (132536/13260) =
64/3315 - 33134/3315 =
-33070/3315 =
-9.97586726998 =
-$9.98, rounded to the nearest cent
(i.e., the expected value of the bet is a loss of $9.98)
Side length in centimeters is
A) 130 cm
3 sig figs
multiply
9.00*4.25=38.25
round to 3
38.3 square inches
The rule, letting d=discriminant:
d>0, two real solutions
d=0, one real solution
d<0, no real solution (but there are two imaginary solutions)
So if it has only one real solution, the discriminant is equal to zero.
