Answer:
In total,
permutations of three items can be selected from a group of six distinct elements.
In particular, there are
ways to order three distinct items.
.
Step-by-step explanation:
The formula
gives the number of ways to select and order
items from a group of
distinct elements.
To select and order three items from a group six distinct elements, let
and
. Apply the formula:
.
In other words, there are
unique ways to select and order three items (select a permutation of three items) from a group of six distinct elements.
Consider: what's the number of ways to order three distinct items? That's the same as asking: how many ways are there to select and order three items from a group of three distinct elements? Let
and
. Apply the formula for permutation:
.
To find the permutations, start by selecting one element as the first of the list. A tree diagram might be helpful. Refer to the attachment for an example.
Answer:

Step-by-step explanation:
Given the following question:

When x is the numerator of the fraction you multiply each side by the denominator in order to isolate the variable.

The answer is x=4 or x= minus 5 i mean D.
The answer would be 92.5.
The 4 is the tenth
The 7 is the hundredth
The 1 is the thousandth
D.
By looking at the scatterplot, we can identify the ‘trend’, or the general outline of the dots and where they’ll be. Using this, we can predict where a given dot will be in the sequence.
Since the dot for 3 chapters is at 80(roughly) and the dot for 5 chapters is at 140(at the lowest), we can infer that the dot for four chapters will be somewhere in the range of 81-139. From there, we can rule out 140 and 150 as answers, and we can use an inference to pick 120 as the answer.
Hope this helps! :)
