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.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
