Which of the following is the appropriate interpretation for when an event has a probability of 1? Group of answer choices We are absolutely certain that the event will occur. The event will never occur. The relative frequency will be more than 1.

9514 1404 393

  We are absolutely certain that the event will occur

Step-by-step explanation:

An event with probability 1 is certain to occur. There is no chance it will not occur.

We are absolutely certain that the event will occur.

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)

5x+2x=49

7x=49

x=7. 35 apples
