Answer:
x^4 - 81 = 0
(x² - 9)(x² + 9) = 0
Notice that the first of these is itself a difference of two squares:
(x - 3)(x + 3)(x² + 9) = 0
So the solutions are x = 3, x = -3, x = 3i, x = -3i

Step-by-step explanation:
The question is incomplete, as the box plot is not given. A general approach to the question, is as follows:
First, identify the 27 mark on the box plot.
Next, count the number of data less than 27.
Take, for instance, there are 6 dots or marks before 27;
This means that 6 bags contain less than 27 ounces
72% = 72/100
72/100=36/50=18/25
