A bag contains 6 purple marbles and 24 blue marbles which statements are characteristic of a representative sample.
80% of the marble are blue
There are more purple marbles than blue marbles
One out every five marbles is purple

80% of the marbles are blue and one out of every five marbles is purple.

Step-by-step explanation:

First of all, there are clearly not more purple marbles than blue marbles, so we can get that one out right away.

To find the percent of blue marbles in the bag you have to add 24 and 6, which is 30. Then, you divide 24 by 30, which is 0.8, or 80%, so that is correct.

Finally, to find out if this proportion is correct, you have to put 6/30 and if you simplify that fraction, you get 1/5. So that is also correct.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
