A bag contains a total of 150 green and blue marbles. Without looking, a student chooses a marble, records the color, and places it back in the bag. The student records 4 green marbles and 11 blue marbles. Which is the best prediction of the total number of blue marbles in the bag? (1 point)
There are 15 marbles total that were chosen. The ratio of blue marbles to green marbles chosen is 11:4.
To find the best prediction of the total number of blue marbles in the bag, we can set up a proportion:
11/4 = x/150
Solving for x, we get:
x = (11/4) * 150
x = 412.5
Since we cannot have a fraction of a marble, the best prediction for the total number of blue marbles in the bag would be 412.
