Answer:
There should be 18 blue marbles in the representative sample.
Step-by-step explanation:
Given that a bag contains 9 white and 54 blue marbles, if a representative sample contains 3 white marbles, to determine how many blue marbles would you expect to contain the following calculation must be performed:
9 = 3
54 = X
54 x 3/9 = X
162/9 = X
18 = X
Therefore, there should be 18 blue marbles in the representative sample.
X is greater than or equal to 74
(it would be this sign: > BUT WITH A LINE UNDER)
Answer:
I'm sure the answer to this is: x<20/3
The answer is 6 degrees below the high.
89+6=95
95-12=83
