Determine whether the underlined numerical value is a parameter or a statistic. explain your reasoning. upper a survey of 42 out of hundreds in a dining hall showed that modifying 40.5 % with underline enjoyed their meal. a survey of 42 out of hundreds in a dining hall showed that 40.5% enjoyed their meal. choose the correct answer below.

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.
