Could someone me with this? what are the minimum, first quartile, median, third quartile, and maximum of the data set?

18, 20, 11, 10, 8, 6, 12, 4

a) minimum 4; first quartile 7; median 10.5; third quartile 17.5; maximum 20
b) minimum 4; first quartile 5.5; median 12.75; third quartile 15; maximum 20
c) minimum 4; first quartile 8.75; median 12.75; third quartile 17.5; maximum 20
d) minimum 4; first quartile 7; median 20.5; third quartile 15; maximum 20

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

the square root of what number? if you add that, then someone will probably answer the question.
