Arthur is using the dot plots to compare two sets of data. Both plots use the same number line. Which choice most likely describes the data sets Arthur is comparing?

a. Plot 1 - shoe sizes of boys in the class

Plot 2 - shoe sizes of girls in the class

b. Plot 1 - the weights of sumo wrestlers

Plot 2 - the weights of Olympic gymnasts

c. Plot 1 - weights of 25 books in grams

Plot 2 - weights of the same 25 books in kilograms

d. Plot 1 - cost of new homes in dollars

Plot 2 - heights of newborn babies

A

Step-by-step explanation:

answer a is the most relatable to eachother therefore it is the most likely to be ploting

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:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
