The side of a rhombus and the half-diagonals form a right triangle. The length of the other half-diagonal is found from the Pythagorean theorem to be
... d = √((10 cm)² -(6 cm)²) = √(64 cm²) = 8 cm
The length of the other diagonal is 16 cm.
The area is half the product of the diagonal lengths, so is
... area = (1/2)(12 cm)(16 cm) = 96 cm²
Answer:
Systematic sampling
Step-by-step explanation:
Systematic sampling is a form of random sampling that involves sampling based on numbering the members of the population and selecting the sample at a given specified interval.
However, when the systematic sampling technique is used, it is necessary to ensure that the numbering of the population does not result in an ordering of the population such that the selected sample will consist more of a particular group of the population.
The answer is 3.75.
Since the length of 'b' is one-half that of 7.5 based on the diagram (we know this because the partial radii connecting the two lines, or chords, are the same length, meaning the two chords are equal);
<u>7.5</u> ⇒ 3.75<u>
</u> 2
