Answer:
D. 2040
Step-by-step explanation:
population increases by about 1 million every 10 years
in 2010, it's about 8
11 - 8 = 3
2010 + 30 = 2040
So first add all of the marbles together: 3+2+6+9=20
Because there are 20 marbles together, that would be your denominator.
All of the other numbers would be your numerator. So you would have:
3/20 green marbles
2/20 yellow marbles
6/20 blue marbles
9/20 red marbles
So your answer would be the probability of picking a red marble from the bag is 9/20 or 45%
They are similar because they both contain variables.
We know, Circumference = 2π * x/2 = <span>π x
In short, Your Answer would be: Option B
Hope this helps!</span>
