6. Bob and Sue were two students who were having a friendly argument about who had been more consistent in their math quiz grades. Bob had scored: 80, 90, 95,
85 & 70 on his quizzes. While Sue had scored: 70, 75, 90, 100, & 95 on hers.
Find the mean absolute deviation for each of them and then answer the two
questions:
Bob's mean:
Sue's mean:
Bob's MAD:
Sue's MAD:
Who's doing better on the quizzes?
Who's more consistent in their quiz scores?

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:

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

answer: 7

step-by-step explanation:

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
