have a great day!!!
Answer:
It is similar to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8)
Step-by-step explanation:
Dilated triangles are <em>never congruent</em>, only <em>similar</em> (unless the dilation factor is exactly 1).
The coordinates of an image dilated about the origin are those of the pre-image multiplied by the dilation factor. For example,
A' = 2A
A'(8, -12) = 2×A(4, -6)
These facts are all you need to know to choose the correct answer (shown above).
Answer:
27.1
Step-by-step explanation:
Given:
mean=25
standard deviation=4
z0.70=0.525

z*sd = x-mean= 2.1
the lowest score for the top 30%: x=27.1
