The <em><u>correct answer</u></em> is:
A box and whisker plot
Explanation:
A box and whisker plot, or a box plot, displays what is called the "five number summary." This includes:
Median; LQ (lower quartile, or the median of the lower half of data); UQ (upper quartile, or the median of the upper half of data); lowest value; and highest value.
This will show the spread of data, and the mean can easily be added to this diagram.
Answer and Step-by-step explanation

These are the next three numbers in the pattern :-12, 14, -16
Answer:

Step-by-step explanation:
Note that
sin135° = sin(180 - 135)° = sin45° =
= 
Answer is choice B: the circumference of a circle is the same as perimeter and is defined by πd (or pi times diameter) We can cut this in half because we are working with a semicircle: so we have 6π which approximates to the value in answer
when using 3.14 for pi
Woops: forgot to add the diameter of 12 so we would have 30.84
