To identify which data set is represnted by the box plot, find the data set that has the exact five-nunber summary of the box plot given.

<h3>What is a Box Plot?</h3>

If you identify the five-number summary of a data set, you can easily draw a box plot, because the values of each of the five-number summary is exactly what you are going to see on a box plot.

The min, max, lower and upper quartile, and median, which are the five-numnber summary of a data set is displayed as shown in the box plot attached below.

Therefore, to identify which data set is represnted by the box plot, find the data set that has the exact five-nunber summary of the box plot given.

(5x^5) - (80x^3)<br> factoring

elena55 [62]

Answer:

Factoring the term $(5x^5) - (80x^3)$ we get $\mathbf{5x^3(x-4)(x+4)}$

Step-by-step explanation:

We need to factor the term $(5x^5) - (80x^3)$

First we can see that $5x^3$ is common in both terms

So, taking $5x^3$ common:

$(5x^5) - (80x^3)\\=5x^3(x^2-16)$

We can write $x^2-16$ as $(x)^2-(4)^2$

$=5x^3((x)^2-(4)^2)$

Now we can solve $(x)^2-(4)^2$ using the formula: $a^2-b^2=(a+b)(a-b)$

We can write:

$=5x^3((x)^2-(4)^2)\\=5x^3(x-4)(x+4)$

So, factoring the term $(5x^5) - (80x^3)$ we get $\mathbf{5x^3(x-4)(x+4)}$

What must be true in order for p (a or b) = p(a) + (b)

anyanavicka [17]

A and B must be disjoint. You have, by the inclusion/exclusion principle, that

$\mathbb P(A\cup B)=\mathbb P(A)+\mathbb P(B)-\mathbb P(A\cap B)$

where the last term is required to prevent double counting. When $A$ and $B$ are disjoint, you have $A\cap B=\emptyset$ and $\mathb P(A\cap B)=0$ , leaving you with

$\mathbb P(A\cup B)=\mathbb P(A)+\mathbb P(B)$
