Answer:
Figure ABCD is congruent to figure A’B’C’D’. So can say that Figure ABCD is similar to figure A’B’C’D’.
Step-by-step explanation:
It is given that Figure ABCD is reflected about the y-axis to obtain figure A’B’C’D’.
Reflection is a rigid transformation it means the size and shape of the figure remains same but reflected across a line of reflection.
In other words we can say that Figure ABCD is congruent to figure A’B’C’D’.
Corresponding parts of congruent figures are same.
Therefore, the correct statement is "Figure ABCD is similar to figure A’B’C’D’".

A. We are going to form 7 digit numbers from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
where the first digit cannot be 0 or 1.
so we have 8 choices for the 1. digit, and 10 choices for all the other 6 digits.
this means there are
possible numbers.
b.
consider the numbers which start with 911. There are
such numbers, since for the 4th, 5th, 6th and 7th digits we have 10 choices.
then we remove this number, from the one we found in a:
There are in total
numbers which don't start with 911.
