The interquartile range (IQR) is 20

You find this by subtracting the values of Q3 and Q1
Q3 is the right most edge of the box which is 45
Q1 is the left most edge of the box which is 25

IQR = Q3 - Q1 = 45 - 25 = 20

Side Note: The median is not 45. The median is actually 40 since this is the middle line of the box, which is in between 35 and 45

. Here is an equation 2x + 9 = -15. Write three different equations that have the same solution as 2x + 9 = -15. Show or explain

Anettt [7]

Answer:

1. $x-3=-15$
2. $2x=-24$
3. $2x-3=-27$

Step-by-step explanation:

Given the following question:

$2x+9=-15$

To find three equations that have the same solution as the given equation we have to first solve the equation.

$2x+9=-15$
$9-9=0$
$-15-9=-24$
$2x=-24$
$2x\div2=x$
$-24\div2=-12$
$x=-12$

<u>Equation one:</u>
$x-3=-15$
$-3+3=0$
$-15+3=-12$
$x=-12$

<u>Equation two:
</u> $2x=-24$
$2x\div2=x$
$-24\div2=-12$
$x=-12$

<u>Equation three:</u>
$2x-3=-27$
$-3+3=0$
$-27+3=-24$
$-24\div2=-12$
$x=-12$

Hope this helps.

How to solve inter quartile range of the given data set? 3,9,12,15,16,18,21

s2008m [1.1K]

Answer:

Step-by-step explanation:

3,9,12,(15),16,18,21

mean (middle number) = 15

Q1 = 9.....the middle number of the numbers before the mean

Q3 = 18...the middle number of the numbers after the mean

interquartile range (IQR) = Q3 - Q1 = 18 - 9 = 9 <==

Wilson purchased a notebook for class for $5. He also purchased x pens for 1.50 each. Write the linear function to model Wilson'

Romashka-Z-Leto [24]

Answer:

$p=1.5x+5$

Step-by-step explanation:

Let the total purchase be given as 'p' dollars.

Given:

Price of a notebook = $5

Price of a pen = $1.50

Number of pens purchased = 'x'

Number of notebooks purchased = 1

So, cost of 'x' pens can be obtained using unitary method and is given as the product of price per pen and number of pens.

So, price of 'x' pens = Price per pen $\times$ Number of pens

Price of 'x' pens = $1.50\times x=1.5x$

Now, total purchase price will be equal to the sum of the price of a notebook and price of 'x' pens.

Therefore, the total purchase price is given as:

Total price = 1 notebook price + 'x' pens price

⇒ $p=5+1.5x\ or\ \\p=1.5x+5$
