<h3>Answer: B. 2</h3>

How I got that answer:

The data set for Marcus is

2, 3, 5, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 10, 10

The five number summary is

min = 2
Q1 = 6
median = 7
Q3 = 8
max = 10

So the interquartile range (IQR) is

IQR = Q3 - Q1

IQR = 8 - 6

IQR = 2

What is the slope intercept form of the equation 4x-8y=72

Masteriza [31]

Answer:

y = 1/2x - 9

General Formulas and Concepts:

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Standard Form: 4x - 8y = 72

<u>Step 2: Find slope-intercept form</u>

Subtract 4x on both sides: -8y = 72 - 4x
Divide both sides by -8: y = -9 + 1/2x
Rewrite: y = 1/2x - 9

Please help! <br> Simplify. Your answer should contain only positive exponents.

maxonik [38]

Answer:

$\frac{1}{4k^3}$

Step-by-step explanation:

It's already in a form that only ha positive exponents. Just to state it though you could rewrite it as $k*(4k^{4})^{-1}$ or $k*4^{-1}*k^{-4}$ The question asks for positive exponents though so yu don't need to do that.

You also need to know $\frac{x^a}{x^b}=x^{a-b}$ so in this case $\frac{k}{k^4}=\frac{k^1}{k^4} =k^{1-4}=k^{-3}=\frac{1}{k^3}$

so $\frac{k}{4k^4}=\frac{1}{4}*\frac{k}{k^4}=\frac{1}{4}*\frac{1}{k^3}=\frac{1}{4k^3}$
