First, set these expressions equal in an equation. solve for x, then multiply x by 3 because there are 3 sides. the perimeter is 12
Answer:
12, Increase
Step-by-step explanation:
12 is by far the lowest in the set, and removing the number would raise the mean.
Answer:
59
Step-by-step explanation:
F = 1.8c + 32
F = 1.8(15) + 32
F = 27+32
F = 59
Answer:
- 3.027
Step-by-step explanation:
First price = 10000 ; second price = 700
Number of tickets sold = 11000
Ticket cost = $4
Probability that a ticket wins grand price = 1 / 11000
Probability that a ticket wins second price = 1 / 11000
X ____ 10000 _____ 700
P(x) ___ 1 / 11000 ___ 1/11000
Expected winning for a ticket buyer :
E(X) = Σx*p(x)
E(X) = (1/11000 * 10000) + (1/11000 * 700) - ticket cost
E(X) = 0.9090909 + 0.0636363 - 4
E(X) = - 3.0272728
E(X) = - 3.027
