Find the number of sides of a regular polygon if the sum of the its interior angles is 1620

(x - 2) * 180 = 1620

x -2 = 1620/180

x = 11

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%

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
