Simplify the expression. 2(3 y - 7) - 5 y (2 - y )

5 y2 - 4 y - 14
5 y2 + 4 y + 14
-5 y2 - 4 y - 14
y2 + 16 y - 14

Step-by-step explanation:

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%
