Based on the ratio of blue marbles to total marbles in the sample that Conor counted (3 blue marbles out of 10 marbles), we can calculate the proportion of blue marbles in the entire bag of marbles.
Using this proportion (3 blue marbles out of 10 marbles), we can set up a ratio to find out how many blue marbles will be in the entire bag:
$$
\text{Blue marbles} = \frac{3}{10} \times 600 = 180
$$
Therefore, we can predict that there will be 180 blue marbles in the bag.
Conor has a bag of marbles. He counts out 10 marbles and finds that there are 3 blue marbles among them. If the bag has 600 marbles, predict how many will be blue.(1 point) explain
