Mean of the commissions she earned for the 11 years is $231.13.

Median of the commissions she earned for the 11 years is $233.8.

Mode of the data can be any number from the given amounts.

Step-by-step explanation:

The given data table is

YearAmount(thousands)

2002           $237.51

2003           $233.80

2004           $206.97

2005           $248.14

2006           $164.69

2007           $292.16

2008           $269.11

2009           $225.57

2010           $255.33

2011           $202.67

2012           $206.53

Mean of the commissions is

Mean of the commissions she earned for the 11 years is $231.13.

The given data set is

237.51, 233.80, 206.97, 248.14, 164.69, 292.16, 269.11, 225.57, 255.33, 202.67, 206.53

Arrange the data in ascending order.

164.69, 202.67, 206.53, 206.97, 225.57, 233.8, 237.51, 248.14, 255.33, 269.11, 292.16

Median of the data is middle term of the data set.

So, median of the data is $233.8.

Most frequently accruing number is known as mode of the data.

In the given data set all amount have same frequency, which is 1. So, mode of the data can be any number from the given amounts.

89

step-by-step explanation:

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)
