I need the answer. Help me out

The answer is where and

Solution sketch:

Apply the Pythagorean theorem to find and which you then use to find and Apply Heron's formula to to find that its area is 10, and then use (base times height over 2) to finish by solving for .

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

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4
