Answer:
18/20
Step-by-step explanation:
There are 20 cards in total. The 9 yellow and brown cards makes 18 cards. Since we want the yellow or brown, the probability is 18 out of 20 cards.
If they started at the south pole every direction is north. Traversing the lattitudes (traveling 20 miles west) doesn't get you any farther from the pole.
So they photographed south pole stuff, mostly snow.

Answer:
20 m
Step-by-step explanation:
Let x is the days and the y is the height of the plant.
Let the change between x and y is linear.
So, the relation between x and y will take the form ⇒ y = ax + b
where a and b are constants.
At x = 30 ⇒ y = 18 ⇒⇒⇒ ∴ 18 = 30 a + b → (1)
At x = 90 ⇒ y = 29 ⇒⇒⇒ ∴ 29 = 90 a + b → (2)
solve (1) and (2) to find a and b
subtract (1) from (2)
∴ 11 = 60 a ⇒⇒⇒ ∴ a = 11/60
substitute at (1) ⇒⇒⇒ ∴ b = 25/2 = 12.5
<u>So, the equation which represents the plants growth is</u>
<u>∴ y = (11/60) x + 12.5</u>
