If the one root of the quadratic equation

is 2 then the other root is

½

Step-by-step explanation:

If 2 is a root:

a(2)² - 5(2) + 2 = 0

4a - 10 + 2 = 0

4a = 8

a = 2

2x² - 5x + 2 = 0

2x² - 4x - x + 2 = 0

2x(x - 2) - 1(x - 2) = 0

(x - 2)(2x - 1) = 0

x = 2, ½

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
