I need help with this question

Swordfish :  20%

Lizard Lollies :  50%

Puffer Pops : 30%  

Step-by-step explanation:

Given :

Quantity of Swordfish : 4

Quantity of Lizard Lollies : 10

Quantity of Puffer Pops : 6

Now,

Step 1:

Calculate the total quantity

             4+10+6 = 20

Step 2:

Probability of selecting Swordfish is

               =  20 %

Step 3:

Probability of selecting Lizard Lollies is

            =  50%

Step 4:

Probability of selecting Puffer Pops is

             =  30%

So,

Swordfish :  20%

Lizard Lollies :  50%

Puffer Pops : 30%

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)
