The price per share of electric company's stock during 9 days, rounded to the nearest dollar, was as follows: 16, 17, 16, 16, 18, 18, 21, 22, 19. Use a box plot to determine how much greater the third quartile's price per share was than the first quartile's per share

$4.0

#See solutions for details.

Step-by-step explanation:

#Given our share prices as:16, 17, 16, 16, 18, 18, 21, 22, 19

# I have used to plot a box plot and determine the first and third quartile price difference:

Hence the third quartile is greater than the first quartile by $4.0

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
