A geologist collected data on 11 colleagues. The geologist had to dig hundreds of feet to reach the minerals they were looking for. They shared their data as: 110, 250, 230, 230, 122, 286, 115, 299, 98, 142, 188, 198. What is the mean of this data? Enter your answer rounded to two decimal places, like this: 42.53.

206.29

Step-by-step explanation:

(add all answers up and divide by 11)

(206.18)

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

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)
