Answer: Choice B) -4

The lower quartile, also known as Q1 or the first quartile, is the left edge of the box. In this case, that is at -4. We can drop a vertical line from the left edge of the box until we hit -4 on the number line.

Side Note: 25% of the data values are below Q1, while 75% of the data values are above Q1

Which equation shows an example of the associative property of addition?

Nat2105 [25]

The associative property states that we can regroup the terms of an expression and obtain the same result.

We have then:

$a + (b + c) = (a + b) + c$

The expression that complies with this property is given by:

$(-4 + i) + 4i = -4 + (i + 4i)$

Answer:

An equation that shows an example of the associative property of addition is:

a. (- 4 + i) + 4i = -4 + (i + 4i)

Find the volume of the rectangular prism: 1\frac{1}{2}\ \textit{inches},\ 2\frac{1}{2}\textit{inches},\ \ 3\ \textit{inches}1 2

loris [4]

Answer:

$\dfrac{45}{4}\ \text{inches}^3\ \text{or }11\dfrac{1}{4}\ \text{inches}^3$

Step-by-step explanation:

Dimensions of prism

$1\dfrac{1}{2}=\dfrac{3}{2}\ \text{inches}$

$2\dfrac{1}{2}=\dfrac{5}{2}\ \text{inches}$

$3\ \text{inches}$

Volume is given by

$V=\dfrac{3}{2}\times \dfrac{5}{2}\times 3=\dfrac{45}{4}\ \text{inches}^3\\ \text{or }11\dfrac{1}{4}\ \text{inches}^3$

The volume of the rectangular prism is $\dfrac{45}{4}\ \text{inches}^3\ \text{or }11\dfrac{1}{4}\ \text{inches}^3$ .

In a random sample of 30 sixth graders, 9 had traveled outside of the United States. There are a total of 120 sixth graders in t

Aleksandr-060686 [28]

36 students have traveled outside of the United States, when there are total 120 sixth graders.

<u><em>Explanation</em></u>

The number of students traveled outside of the United States is 9 when there is total 30 sixth graders. So, the ratio of the student traveled to the total students will be $9: 30 = 3: 10$

Now there are total of 120 sixth graders in the school and lets assume the number of students traveled outside the United states is $x$ . That means the ratio...

$x: 120 = 3:10 \\ \\ \frac{x}{120}=\frac{3}{10} \\ \\ 10x=360\\ \\ x=\frac{360}{10} \\ \\ x= 36$

So, 36 students have traveled outside of the United States.
