<h2><u>Answer:</u></h2><h3>The Line Plot is Below.</h3><h2><u></u></h2><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Turn each fraction into a decimal:</h3>

$1\frac{1}{2}=1.5$

$2\frac{3}{4}=2.75$

$3=3$

$2\frac{3}{4}=2.75$

$2\frac{1}{2}=2.5$

$2\frac{3}{4}=2.75$

$3\frac{3}{4}=3.75$

$3=3$

$3\frac{1}{2}=3.5$

$2\frac{1}{2}=2.5$

$3\frac{1}{2}=3.5$

(I've included the line plot below.)

I am honestly not sure about this answer... try Khan Academy. Or, try breaking it down into steps.

I hope this helped... sorry about that. I will try this concept soon. :)

Find the solution of the following equation whose argument is strictly between 270^\circ270 ∘ 270, degree and 360^\circ360 ∘ 360

Natasha2012 [34]

$\rightarrow z^4=-625\\\\\rightarrow z=(-625+0i)^{\frac{1}{4}}\\\\\rightarrow x+iy=(-625+0i)^{\frac{1}{4}}\\\\ x=r \cos A\\\\y=r \sin A\\\\r \cos A=-625\\\\ r \sin A=0\\\\x^2+y^2=625^{2}\\\\r^2=625^{2}\\\\|r|=625\\\\ \tan A=\frac{0}{-625}\\\\ \tan A=0\\\\ A=\pi\\\\\rightarrow z= [625(\cos (2k \pi+pi) +i \sin (2k\pi+ \pi)]^{\frac{1}{4}}\\\\k=0,1,2,3,4,....\\\\\rightarrow z=(625)^{\frac{1}{4}}[\cos \frac{(2k \pi+pi)}{4} +i \sin \frac{(2k\pi+ \pi)}{4}]$

$\rightarrow z_{0}=(625)^{\frac{1}{4}}[\cos \frac{pi}{4} +i \sin \frac{\pi)}{4}]\\\\\rightarrow z_{1}=(625)^{\frac{1}{4}}[\cos \frac{3\pi}{4} +i \sin \frac{3\pi}{4}]\\\\ \rightarrow z_{2}=(625)^{\frac{1}{4}}[\cos \frac{5\pi}{4} +i \sin \frac{5\pi}{4}]\\\\ \rightarrow z_{3}=(625)^{\frac{1}{4}}[\cos \frac{7\pi}{4} +i \sin \frac{7\pi}{4}]$

Argument of Complex number

Z=x+iy , is given by

If, x>0, y>0, Angle lies in first Quadrant.

If, x<0, y>0, Angle lies in Second Quadrant.

If, x<0, y<0, Angle lies in third Quadrant.

If, x>0, y<0, Angle lies in fourth Quadrant.

We have to find those roots among four roots whose argument is between 270° and 360°.So, that root is

$\rightarrow z_{2}=(625)^{\frac{1}{4}}[\cos \frac{5\pi}{4} +i \sin \frac{5\pi}{4}]$

What are the common factors of 18 and 30? What do they represent?

Zolol [24]

Factor out 18.

The factors for 18 are as listed:

1, 2, 3, 6, 9, 18

Now factor out 30.

The factors for 30 are as listed:

1, 2, 3, 5, 6, 10, 15, 30

Now look at the factors that are both factors for 18 and 30.

So, the common factors are 2, 3, and 6.

Did you ever purchase a bag of M & M Peanut candies and wonder about the distribution of the colors ? A recent article repor

Vika [28.1K]

Filling in the frequency table according to the colors observed and expected on the M & M Peanut candies is as follows:

<h3>Frequency Table:</h3>

Color Brown Yellow Red Green Orange Total

<h3>Absolute Frequencies</h3>

Observed Frequency 67 22 51 24 24 188

Expected Frequency 56 38 38 38 18 188

<h3>Relative Frequencies:</h3>

Observed Frequency 36% 12% 27% 13% 13%

Expected Frequency 30% 20% 20% 20% 10%

<h3>What is a frequency table?</h3>

A frequency table is a display of the number of occurrences of a particular value or characteristic.

A frequency table makes it easy to display and interpret a distribution of data.

The absolute frequencies shows the absolute values of the observed and expected frequencies, while the relative frequencies shows the percentage values of the observed and expected frequencies.

<h3>Data and Calculations:</h3>

Color Brown Yellow Red Green Orange Total

Observed Frequency 67 22 51 24 24 188

Expected Frequency 30% 20% 20% 20% 10% 100%
