The water level in Spanaway Lake changes at an average of -2/20 feet every year. How much would the water level change over a 8 year period?

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%

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
