You are trying to improve communication with your staff by posting graphs of significant statistics on the employee bulletin board. You recently calculated the percentage of time employees spend on each of six major tasks. Because you would like the employees to appreciate each task as a percentage of their whole day, you will post these figures using a pie graph.

Yes, the Pie Graph is the right choice.

Step-by-step explanation:

A Pie Graph, or Sector Graph is one of the good options to display, usually relative frequencies, proportionally.

In a Pie Graph the focus is to show the importance of each observation, or category in comparison with the whole.

You need to be careful with the angles, since 180º is equal to 50%, 90º to 25% and 360º is equal to 100% so each "slice" each portion must directly proportional to the angles of one circle.

Since the goal is to show the importance of each work to the whole team, definitely a Pie Graph is one the appropriate one to pick.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
