PLZ HELP ME IM RUNNING OUT OF TIME

-0.69 degrees

Step-by-step explanation:

You can find the mean of a set of values by taking the sum of them, and then dividing that sum by the number of values you had to start with.

Hope this helped!

-0.69

Step-by-step explanation:

Mean: ( -3.36 + 1.74 - 1.81 + 0.67)/4 = -0.69

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)

step-by-step explanation:

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
