The stock of Company A lost 2.75% today to $77.80. What was the opening price of the stock in the beginning of the day?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

30 people weigh 160 pounds or more

jml angle lkj & angle mj = lm

2/3=10/15

1/5=3/15

10+3=13/15
