! Means starting from that number multiply by every number down to 1.
5!= 5•4•3•2•1 = 20•6=120
2!= 2•1=2
120+2=122 :)

Hope this helps and please give brainliest!
Download photomath it will give u the answer
What im thinking is this: F(a) = f(b) so have 2 equations written and plug a into one and b in the other
(a-2)^3+8 = a^3-8+8 = a^3
= a^3 = b^3 square root both side = a=b
<span>(b-2)^3+8 = b^3-8+8 = b^3
Thus it is 1:1.</span>
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
