The dot plots below show the test scores of the seventh-grade students and the fifth-grade students at a local school.

Which statement compares the shape of the dot plots?

a) only the fifth-grade data points are clustered toward the left of the plot.

b) only the seventh-grade data points are clustered toward the left of the plot.

c) Only the fifth-grade data points are disturbed fairly evenly.

d) only the seventh-great data points are disturbed fairly evenly.

Step-by-step explanation:

i think its b

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)
