Answer:
price = $190
quantity = 950 tickets
Step-by-step explanation:
revenue = price * quantity
n = number of $10 price reductions
price = 300 - 10n
quantity = 400 + 50n
r = (300 - 10n)(400 + 50n)
recognize these as the factors of a quadratic that opens down
the vertex will therefor be the maximum revenue
the roots are:
300 - 10n = 0
300 = 10n
n = 30
400 + 50n = 0
50n = -400
n = -8
vertex is at mid point of the roots
n = (-8 + 30)/2
n = 11
price = 300 - 10n
price = 300 - 10(11)
price = 190
quantity = 400 + 50n
quantity = 400 + 50(11)
quantity = 950
Answer:
P(E) =5/9
P(F)=P(E) × P(B<Y<R) = 5/54
Step-by-step explanation:
Let E be events that gives no two number on the dice
Probability P(E) = (6 × 5× 4 )/(6×6×6)
P(E) = 130/ 216 = 5/9
Probability P(B<Y<R) = 1/6
Probability P (F) = P(E) × P(B< Y < R)
P(F) = (5/9 )×( 2/6) = 5/ 54
