The transformation from parallelogram LMNO to parallelogram L'M'N'O' is a reflection across the x-axis
<h3>How to determine the transformation?</h3>The complete question is added as an attachment
From the graph, we have the following highlights:
- Parallelogram LMNO and parallelogram L'M'N'O' are on either sides of the x-axis
- They are equidistant from the x and y axes
- They have equal dimensions
This means that parallelogram LMNO is reflected across the x-axis to get parallelogram L'M'N'O'
Hence, the transformation from parallelogram LMNO to parallelogram L'M'N'O' is a reflection across the x-axis

Answer:
Step-by-step explanation:
From the given information:
There are 30 collections of gems, of which 8 are worthless;
Thus, the number of the genuine diamonds = 30 - 8 = 22.
Let X = random variable;
X consider the value as 0 (for 2 worthless stone selection),
X = 1200(1 worthless stone & 1 genuine stone)
X = 2400 (2 genuine stones selected)
However, the numbers of ways of selecting and chosen Gems can be estimated as:
Thus;
To find E(X):
E(X) = (0 × 0.0644) + (1200 × 0.4046) + (2400 × 0.5310)
E(X) = 0 + 485.52 + 1274.4
E(X) = 1759.92
