Using unit concepts, it is found that:
- a) Grams.
- b) Grams.
- c) Grams squared.
- d) Grams squared.
-----------------------------
- For a data-set, the standard deviation has the same unit as the data-set, both for the sample and the population.
- The variance has the unit squared, both for the sample and the population.
- For example, if the data-set is in metres, the standard deviation will be in metres while the variance will be in squared metres.
-----------------------------
In this question, the data-set is in grams.
- The standard deviation, both for the sample and the population, in items a and b, will be in grams.
- The variance, both for the sample and the population, in items c and d, will be in grams squared.

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The circle tangent theorem states that tangents which meet at the same point are equal in length. Hence:
The missing lengths are 8, 6, 9 and 16.
Perimeter of the polygon = 2(8) + 2(6) + 2(9) + 2(16) = 78 cm
The perimeter of the polygon that circumscribes the circle is 78 cm
