each little square = 1 square inch
the design takes up 21 squares so area is 21 square inches
the perimeter = 6 +2+3+3+3+5 = 22 inches
Step-by-step explanation:
This is an arithmetic sequence. The expressive formula for an arithmetic sequence is aₙ = a₁ + (n-1)d, where a₁ is the first term and d is the common difference. In this case, a₁ = 12 and d = -1. We have aₙ = 12 + (n - 1) * (-1) = 12 - n + 1 = -n + 13. aₙ = -n + 13. Hope this helps!
and
both have a common denominator, so you can combine them into a single fraction:

You cannot simplify this fraction further:

Answer:
D (compute the mean)
Step-by-step explanation:
A box plot is a visual representation of the 5-number summary of a set of data. It is plotted against a number line.
The 5-number summary of the data set is most easily determined from an ordered set of the data, so ordering the data is usually the first step. Since the 5-number summary is plotted against a number line, the next steps are finding the 5-number summary, and creating a suitable number line.
__
The business of adding the data and dividing by the number of data items is a description of computing the mean of the data. That value is not part of the 5-number summary, and is not needed in the creation of the box plot.
