Find A UB.
A)
{3,7)
B)
{3,5,6,7}
{2,3,5,7,8,9,12}
D)
{3,5,6,7,8,11,12}

D

Step-by-step explanation:

3,5,6,7,8,11,and 12

Because that's the union

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

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
