Option B makes the most sense, because if you follow the steps, they fit perfectly into each other!

4 0

Answer:

The second choice is correct.

Step-by-step explanation:

Reflecting ABC across the y-axis will negate the x-coordinates, which will place it directly above triangle DEF.  Counting down from A to D, B to E and C to F, we see that each is 5 units above the image; this means a translation 5 units down will finish mapping the pre-image to the image.  Since they are mapped on top of each other, they are congruent.

The tallest living man at one time had a height of 262 cm. The shortest living man at that time had a height of 68.6 cm. Heights
AysviL [449]

Answer:

more the z-score more will be the extreme. therefore tallest man has high extreme

Step-by-step explanation:

Formula for z-score: \frac{X-\mu }{\sigma}

where

X is height of tallest man

μ mean height

σ is standard deviation

z score for tallest is

z-score = \frac{ 262 - 175.32}{8.17} = 10.60

similarly for shortest man

z-score = \frac{68.6 - 175.32}{8.17} = - 13.06

more the z-score more will be the extreme. therefore tallest man has high extreme
