I believe the correct answer would be $67.22 as the sum of all three
Rigid mapping is used to illustrate rigid transformation.
The rigid mapping rules are:
- <em>(a) (x, y)->(y,x)
</em>
- <em>(c) (x, y)->(-y, x)
</em>
- <em>(d) (x, y)-> (-y +4, X-6)
</em>
- <em>(e) (x, y)->(x + 4, y-5)
</em>
- <em>(f) (x, y)->(x, x+y)
</em>

All transformations are rigid except dilation.
This is so, because dilation <em>changes the size </em>of the function that is being transformed, while others do not.
Dilations are represented by scale factors (<em>product or division</em>)
From the list of given options
<em>(b) (x, y)->(3x, y) and (c) (x,y)-> (3)</em> are non-rigid mapping because they represent dilations.
Hence, the rigid mapping rules are:
- <em>(a) (x, y)->(y,x)
</em>
- <em>(c) (x, y)->(-y, x)
</em>
- <em>(d) (x, y)-> (-y +4, X-6)
</em>
- <em>(e) (x, y)->(x + 4, y-5)
</em>
- <em>(f) (x, y)->(x, x+y)
</em>

I would say that statistics is a mathematical subject that allows you to explain scientific data. In a similar fashion, you could use mathematics to explain the various idea in physics as you can use statistics to interpret the results of experiments and the data collected.
Hope that helped!
