I know its a scale factor of .5, i just don't know if its the rotation or reflection answer.
The number of unique combinations that can be formed by picking one object from each set is =960. That is option C.
<h3>Calculation of unique combinations of a number set</h3>
Number combination is a mathematical technique that shows the number of possible arrangements in a collection of items.
The first set of objects = 4. There are a total of 4 possibilities.
The second set of objects = 5. There are a total of 5 possibilities
Therefore from first and second set, the total number of possibilities = 4×5 = 20
For the whole set, the total possibilities;
= 4×5×6×8
= 960
