Answer:
Reflection: A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
Dialation: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)
Step-by-step explanation:
A(−5,3),B(−2,3),C(−2,1),D(−5,1)
To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:
A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
To dialate by a scale factor of 2 you multiple everything by 2 and you should get: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)

A group of friends spent 1, 0, 2, 3, 4, 3, 6, 1, 0, 1, 2, and 2 hours online last night. What are the 1st and 3rd quartiles for
Ostrovityanka [42]
Arrange the numbers from smallest to largest:
0,0,1,1,1,2,2,3,3,4,6
Split the data in the middle, since there is an odd amount of numbers take an even amount on each side:
0,0,1,1,1,2,2,3,3,4,6
Lower half: 0,0,1,1,1
Higher half: 2,3,3,4,6
1st quartile is the middle value of the lower half: 1
3rd quartile is the middle value of the higher half: 3
