Through common sense a number is already at it’s 100%. And so by increasing The percentage of the number you are also increasing the number itself.
For example take the number 10. If you increase it by 20% you'll take 2 out of 10 and add it to original number which will result in 12, 20% more or 120% in total. And so if you apply the same situation but with a hundred percent, you will double the number and get a number of 20 or 200%. An increase of a 100% plus the original 100%. If this doesn't make sense however, I'm sorry as my "explaining" skills suck
Answer:
40
Step-by-step explanation:
31 + 9=40
cause u need to change the negative into positve and change the minus into plus
<span>99(100x)+31=89
=> 9900x + 31 =89
=> 9900x = 89 - 31=58
=> x = 58/9900
Hope it helps !!!</span>
Answer:
The approximate probability that 10 squared centimeters of dust contains more than 10110 particles is 0.1357
Step-by-step explanation:
For a sample of 10 sqaured centimeters of dust, the total amount of asbestos particles has a Poisson distribution with a mean of 1000/1 * 10 = 10000.
We will approximate this probability to a normal distribution. The variance is also 10000 (because it is poisson), therefore the standard deviation is √10000 = 100. Lets call X the distribution, and W its standarization, given by
We have
Where 
is the cummulative distribution function of a standard normal distribution. The values of are well known and they can be found in the attached file.
We conclude that the approximate probability that 10 squared centimeters of dust contains more than 10110 particles is 0.1357.
1. It's asking if the hourly pay seems linear or nonlinear. Which is practically you just giving one or the other.
2. It's asking where the number cluster close together. Which is from 4-6
Those are the only 2 I see difficult to understand
