I believe the answer would be the first choice (4 of each color) because of how similar the probabilities are. The table showed that the probabilities are very similar, and this model represents that.
Answer:
30 degrees
Step-by-step explanation:
90 + 60 + x = 180
150 + x = 180
-150 -150
x = 30
1) the car has travelled 210 miles in 3.5 hours
2) No because the line stops at (1,50)
x² - 80 = 0
Add 80
to each side: x² = 80
Square root
each side: x = √80
Look it up: x = + 8.944... (rounded)
and
x = - 8.944... (rounded).

Here's a cleaner solution:
x² - 80 = 0
Add 80
to each side: x² = 80
Square root
each side: x = √80
But 80 = 16 · 5
So √80 = √16 · √5
√16 = 4, so x = 4 √5
