The exterior angles of any polygon will always add up to 360 degrees. Since we know all the values for every exterior angle, we can simply make the following equation:

3x + (x + 50) + 4x + (2x + 40) = 360

Simplify:

10x + 90 = 360
10x = 270
x = 27

If you want me to explain anything I did here, just ask :)

KatRina [158]

Answer: 0.1

Step-by-step explanation:

Given : A Houston department store sampled 80 items sold in January and found that 8 of the items were returned.

In other words, sample size : <em>n</em>=1040

Number of items returned : <em>x</em>= 8

Let <em>p</em> be the proportion of items returned for the population of sales transactions at the Houston store.

As per sample , the sample proportion of items returned for the population of sales transactions at the Houston store is :

$\hat{p}=\dfrac{x}{n}=\dfrac{8}{80}=0.1$

As we know that , <em>the sample proportion is the best estimate of the population proportion.</em>

Therefore,a point estimate of the proportion of items returned for the population of sales transactions at the Houston store is 0.1.

Which equations and/or functions represent the graphed line? Select three options.

Reil [10]

Answer:

$y=\frac{1}{2}x+2$

Step-by-step explanation:

Let's take points (2,3) and (-4,0)

Slope

$m=\frac{y_2-y_1}{x_2-x_1}\\\Rightarrow m=\frac{0-3}{-4-2}\\\Rightarrow m=\frac{3}{6}\\\Rightarrow m=\frac{1}{2}$

So,

$y=mx+c\\\Rightarrow y=\frac{1}{2}x+c$

To find c we put value of (2,3) in the equation

$3=\frac{1}{2}2+c\\\Rightarrow 3-1=c\\\Rightarrow 2=c$

Equation of line

$y=\frac{1}{2}x+2$
