Answer: HIJK is a parallelogram because the midpoint of both diagonals is <u>(1,0)</u> , which means the diagonals bisect each other.

Step-by-step explanation:

Given: The coordinates of parallelogram H I J K as

H is at (- 2, 2), point I is at (4, 3), point J is at (4, - 2), and point K is at (- 2, - 3).

Diagonals : HJ and IK  [join opposite vertices]

Mid point of HJ = (\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})

=(\dfrac{-2+4}{2},\dfrac{2+(-2)}{2})=(1,0)

i.e. Mid point of HJ = (1,0)

Mid point of IK = (\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})

=(\dfrac{4+(-2)}{2},\dfrac{3+(-3)}{2})=(1,0)

i.e. Mid point of IK = (1,0) =Mid point of HJ

<em>When mid points of both diagonals are equal then that means the diagonals bisect each other.</em>

<em />

Thus, HIJK is a parallelogram because the midpoint of both diagonals is <u>(1,0)</u> , which means the diagonals bisect each other.

Step-by-step explanation:

multiples of 11 between 1 and 80 are 11,22,33,44,55,66,77

number of terms=7

P(multiple of 11)=7/80

P(not a multiple of 11)=1-7/80=73/80
