Z = (x - mean)/std dev
z = (46 - 44)/8
z = 2/8
z = 1/4
z = 0.25

A triangle is dilated with the center of dilation at point U. Point E is a vertex of the triangle and point E ′ E' is the corres

Snezhnost [94]

Answer: $scale\ factor=5$

Step-by-step explanation:

By definition, a Dilation is a transformation in which the image has the same shape as the pre-image but size changes.

The center of dilation is a fixed point in the plane, and the scale factor is the ratio of the corresponding sides of the image to the pre-image.

Based on the information provided in the exercise, you know that:

$UE = 2\ cm\\\\U'E'=10\ cm$

Thererefore, you can determine that the scale factor is:

$scale\ factor=\frac{10\ cm}{2\ cm}\\\\scale\ factor=5$
