The results from the last quiz that mr. tham gave his class are 10, 15, 25, 75, 75, 77, 80, 83, 85, and 90. which statistical measure makes these scores seem low overall?

Mean

Step-by-step explanation:

Mean is the average of all results.

Step 1 : Identify the formula of calculating mean

Mean = Sum of all data

             Number of data

Step 2 : Substitute the values in the formula

Mean = 10 + 15 + 25 +75 + 75 + 77 + 80 +83 + 85 + 90

                                        10

Mean = 615

              10

Mean = 61.5 marks

!!

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)
