Question Help
A bag contains 7 green marbles and 35 white marbles. If a representative sample contains 2 green
marbles, then how many white marbles would you expect it to contain? Explain.​

Answer 1

Answer:

10

Step-by-step explanation:

35/7 = 5, so the white marbles appears 5 times often.

If we have 2 green marbles and we want to maintain the same ratio of green to white marbles (so the same assumption that white appears 5 times often) we need to multiply that by 5.
