1) Bar graph<span> Its a diagram that uses proportional-width </span>bars<span> to compare data among categories.One can easily see the mode since the candidates with the same height of graph can easily be seen and at a specific mark.as for the median one can easily see the student who who has attained am a mark thats in the middle.</span>

Answer:

2) Box-and-whisker

Step-by-step explanation:

The Box- and -Whisker helps to show the visual representation and how the data are spread. It focuses attention on the mean, median, and mode of data and also quartiles as well as minimum and maximum values.

order your data
middle point is the median
half the median is the quartile
the mean is the average of set of data
mode the one with the highest frequency

Quadratic equations and complex numbers PLEASE HELPPPP ASAP

kondor19780726 [428]

we are given

$27x^3-1=0$

we can also write it as

$(3x)^3-(1)^3=0$

now, we can use factor formula

$a^3-b^3=(a-b)(a^2+ab+b^2)$

we can use above formula

we get

$(3x)^3-(1)^3=(3x-1)((3x)^2+3x\times 1+(1)^2)$

now, we can simplify it

$27x^3-1=(3x-1)(9x^2+3x+1)$

now, we can set it to 0

$27x^3-1=(3x-1)(9x^2+3x+1)=0$

and then we can solve for x

$(3x-1)(9x^2+3x+1)=0$

$3x-1=0$

$x=\frac{1}{3}$

$9x^2+3x+1=0$

now, we can use quadratic formula

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

now, we can plug values

and we get

$x=\frac{-3\pm \sqrt{3^2-4\cdot \:9\cdot \:1}}{2\cdot \:9}$

$x=-\frac{1}{6}+i\frac{\sqrt{3}}{6},\:x=-\frac{1}{6}-i\frac{\sqrt{3}}{6}$

So, we will get solution as

$x=\frac{1}{3},\:x=-\frac{1}{6}+i\frac{\sqrt{3}}{6},\:x=-\frac{1}{6}-i\frac{\sqrt{3}}{6}$ ...............Answer

How can you dicide if useing common multiples and common factors is useful in solving a problem

geniusboy [140]

Usually the problem asks for you finding common multiples and common factors.

Usually these tools are used to solve a problem involving the first number.

Sometimes using common multiples and common factors are a waste of time but most of the time it just makes it easier to solve the problem.

(Geometry HELP) The perimeter of WXY is ___ cm?

jeka57 [31]

I hope this helps you

QR=WS=2.93

RS=QW =2.04

QS=XR =2.28

RS=XQ=2.04

SY=QR =2.93

RY=QS =2.28

XY=XR+RY=2.28+2.28=4.56

XW=XQ+QW=2.04+2.04=4.08

WY=WS+SY=2.93+2.93=5.86

Perimeter of XYW=XW+WY+XY

Perimeter of XYW=4.08+5.86+4.56

Perimeter of XYW =14.5
