A deck of cards contains red cards numbered 1,2, blue cards numbered 1,2,3,4,5,6,7,8 and green cards numbered 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 ,16,17,18,19. If a single card is picked at random, what is the probability that the card is blue? Give your an

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
