x+y=120_______1
x=4*y_________2
x=4y
substitute 4y for x in equation 1
`4y+y=120
5y=120
eliminate the coefficient of y
y=120/5
y=24
now,input 24 for y in equation 2
`x=4y
x=4*24
x=96
thus, the numbers are
96 and 24

<u><em>The range's difference is the highest and lowest value of the data</em></u>
<u><em>RANGE= 250-150= 100</em></u>
<u><em>The mean would be the sum of all values divided by how many values </em></u>
<u><em>250+200+185+165+160+150+150+150+150 / 10 = 1720/10 = 172</em></u>
<u><em>The variance is the sum of squared deviations </em></u>
<u><em>*n=10 </em></u>
<u><em>s^2 = (250-172)^2+(150-172)^2 / 10-1</em></u>
<u><em>which equals an esitmate of 1034.4444 </em></u>
<u><em>take the square root and you get your final answer of 32.1628</em></u>
<u><em>The measure of the variation isn't typical for all celebs, since the numbers are only based on ten highest networths </em></u>
