Historically, a manufacturer finds that 1% of integrated circuits of a certain type fail during burn-in testing. Burn-in testing results (pass/fail) on the latest shipment of 10,500 circuits are to be analyzed using hypothesis testing to compare the failure rate of this shipment with the historical norm. (1) What is the scientific hypothesis

can you hlep me do homework?

step-by-step explanation:

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:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
