I think the answer may be that an event is as likely as not to happen when the probability of the event happening is 50%, and the probability of the event not happening is 50%. Like a coin toss, the chance you will flip a "heads" is 1/2 or 50%, and the chance that you WON'T flip a heads is also 1/2 or 50%
Answer:
yea I don't understand either kid, it's upside down.
Step-by-step explanation:
Step-by-step explanation:
Original Price = $499
100% of something is the original price. when you mark something up, you are increasing the price. when the clerk marks up merchandise by 28%, they are increasing the price by 28%.
This means that the price is original + markup = 100 + 28 = 128%
Therefore, the retail price is
499 x 128% = $638.72
Answer:
8
sqrt(7)
1/2
20
Step-by-step explanation:
4sqrt(2) * sqrt(2) = 4 * sqrt(4) = 4 * 2 = 8
3sqrt(7) - 2sqrt(7) = sqrt(7)
sqrt(7)/(2sqrt(7)) = 1/2
2sqrt(5) * 2sqrt(5) = 2 * 2 * sqrt(25) = 4 * 5 = 20
