Answer:
Ordered pair of yz is ( 9 , 9 ) and Magnitude of yz is 9√2 unit.
Step-by-step explanation:
Given ordered pair of y and z are ( 14 , -23 ) and ( 23 , -14 ) respectively
To find: Ordered pair of yz and magnitude of yz
To find order pair of yz we subtract ordered pair of y from z.
Ordered pair of yz = ( 23 - 14 , -14 - (-23) )
= ( 9 , -14 + 23 )
= ( 9 , 9 )
Magnitude of yz ,
=
=
=
Therefore, Ordered pair of yz is ( 9 , 9 ) and Magnitude of yz is 9√2 unit.

32 kilowatt-hours.
Step-by-step explanation:
The energy usages per day (in kilowatt-hours) of houses on Hamlet Avenue are listed below:
30, 23, 38, 36, 33.
Therefore, the mean energy usage per day of the houses of Hamlet Avenue will be
=
= 32 kilowatt-hours.
