For -(4)^7
the - is not affected by the power of 7

For (-4)to the power of7 is the same as -4 to the power of 7

It is because 7 is an odd number,the - will not change .Therefore
(-4)^7= -(4)^7

But keep in mind that if the power is an even number , the - will change to + when the situation is (-4)
For example,(-4)^4=(4)^4

Suppose that the number of asbestos particles in a sample of 1 squared centimeter of dust is a Poisson random variable with a me
Maslowich

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

W = \frac{X-\mu}{\sigma} = \frac{X-10000}{100}

We have

P(X>10110) = P(\frac{X-10000}{100} > \frac{10110-10000}{100}) = P(W > 1,1) = 1-\phi(1,1) = 1-0.8643 = 0.1357

Where \phi is the cummulative distribution function of a standard normal distribution. The values of \phi 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.

How did estimate help you place the decimsl point in a product correctly.
Kruka [31]
After you have multiplied but you have all these numbers, look to see how many decimal places the numbers you have multiplied.
Lets say you multiply:
     23.45
   x    2.1
= 49.245
Because your first number had 2 decimal places and your second number had 1 decimal place you add that and that is how many decimal places your product has. In this case there is three.
