Ten needles were randomly selected from a branch of a loblolly pine tree. The stomata (microscopic breathing holes) are arranged in rows. On each needle, four rows are randomly selected and the number of stomata per centimeter for each of the rows was determined. The data below is in the file named stomata. dat on Bb, Column 1 for Needle and Column 2 for numbers of stomata per centimeter. a. Why is the random effects model appropriate here

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20

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)
