The correct answer is c. There is no possible way to know how much the mean age decreases, but we know it definitely will (averages decrease as values less than the average are added to the data.) <span />
Answer:
See Below
Step-by-step explanation:
That rule is a transformation across the x-axys.
Assigne a letter to each point:
A = (2, 7) => A' = (2, -7)
B = (-5, -2) => B' = (-5, 2)
C = (4, -3) => C' = (4, 3)
You would shade 4/6, or 4 parts of the square, since 2/3 is equivalent to 4/6.
Answer:
(9a4 + 2a2 + 5) – (16a4 – 7a2 + 1)
A. 25a4 – 5a2 – 4
B. –7a4 – 5a2 + 6
C. 25a8 + 9a4 + 6
D. –7a4 + 9a2 + 4
5.Multiply 9x2(2x2 + 8x).
A. 18x4 + 72x3
B. 18x2 + 72x3
C. 11x4 – 17x3
D. 90x4
Answer:
A parallelogram
Step-by-step explanation:
One of the definitions of a parallelogram is that opposite sides are equal. In this case, 6 = 6 and 4 = 4 so it is a parallelogram.
On the other hand, if you are talking about the shapes making up the parallelogram, they are triangles because they have 3 sides.
