Here's another one.
See the attached picture.
<u>Answer:</u>
P(3 blue) = 1/5
<u>Steps:</u>
P(3 blue) = 2/3 × 3/5 × 1/2
P(3 blue) = 6/30
P(3 blue) = 1/5
<em>that's 20%</em>
The diver is moving down, so he moved −20 feet. Start with 20 negative tiles and separate them into 5 equal groups. There are 4 negative tiles in each group, so he traveled at a rate of −4 feet per second.
The midpoint formula is ( x + x / 2, y + y / 2)
so....
6+ 2 = 8 / 2 = 4
4 + 8 = 12 / 2 = 6
the midpoint is (4, 6)
