Answer:
814.5 mg remain after 4 hours
Step-by-step explanation:
The multiplier of the original quantity is 1 -5% = 0.95 for each passing hour. The amount remaining after x hours is ...
y = 1000·0.95^x
For x=4, the amount remaining is ...
y = 1000·0.95^4 = 1000·0.81450625
y ≈ 814.5 . . . mg remain after 4 hours
<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>
We know that
volume of a bar of soap=2*4*0.5----> 4 in³
<span>A bar of soap is sold for $3 individually
</span>so
$3/4-----> 0.75 $/in³
<span>A three-pack of the same soap costs $8
so
$8*(3*4)----> 0.67 $/in</span>³
<span>if you buy the three-pack you save-----> [0.75-0.67]=0.08 $/in</span>³
the answer is
$0.08
