<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>
Answer: $506.25
Step-by-step explanation:
1. Find 40% of $843.75
- The decimal value of 40% is 0.4. We can multiply 0.4 by 843.75 to find the discount on the computer.
-> 0.4*843.75= 337.5
2. Now that we have the discount, we can subtract 40% of the original price to find the new price.
843.75 - 337.5 = $506.25
