Helma wants to find the volume of the right rectangular prism shown below. Which equation could Helma use to find V, the volume

V = 30*16*12. To find the volume of a rectangular prism, you just multiply the area of the base (side 1 * side 2) by the height of the prism.

I h(x)is the inverse of f (x)what is the value of h (f (x))
sergeinik [125]

Answer:

h(f(x)) = x

Step-by-step explanation:

Since the functions are inverses h(x) undoes f(x)

That is if f(x) = x then inverse function maps back to x

h(f(x)) = x

Select all the distribution shapes for which it is most often appropriate to use the mean .
goblinko [34]

The distribution shape that tells us for which it is best to use the mean is the skewed.

<h3>What is the mean?</h3>

This is the term that is used to refer to the average score that exists in a data set.

In the question, these are the reasons why the other options are not correct

When we say Bimodal we are talking about the 2 modes that are in a symmetric distribution. This has nothing to do with the mean

The bell shape has to do with how the normal distribution is when it is drawn. It would create a bell shape hence the mean is not useful.

symmetric has to do with the fact that there are mirror images when the vertical line is drawn in the distribution.

Uniformed shapes tells us that the classes are made up of the same frequency all through.

The skewed shape is what tells us if the median is more or if it is less.

Hence we have the answer that the distribution shapes for which it is most often appropriate to use the mean is the skewed.
