Scientific Notation: what’s (2.2 x 10 to the -4) - (3 x 10 to the 2)

Marrrta [24]

Answer:

$2.23\times10^4$

Step-by-step explanation:

In order to get the answer to this question you need to turn the scientific notations into standard form then subtract the two standard forms.

$(2.2\times10^{-4})-(3\times10^2)$

Turn the notations into standard form:

$2.2\times10^{-4} = .00022$

$3\times10^2=300$

$.00022-300=22300$

$=22300$

Turn into notation form:

$22300 = 2.23\times10^{4}$

Hope this helps.

The Department of Commerce in a particular state has determined that the number of small businesses that declare bankruptcy per

skad [1K]

Answer:

B) 0.1487

Step-by-step explanation:

Let $X$ be the discrete random variable that represents the number of events observed over a given time period. If $X$ follows a Poisson distribution, then the probability of observing $k$ events over the time period is:

$P(X=k)=\frac{\lambda^{k} *e^{-\lambda} }{k!}$

Where:

$\lambda=Mean\\k=number\hspace{3}of\hspace{3}events\\e=Euler's\hspace{3}number$

So, the probability that exactly 5 bankruptcies occur next month is:

$P(X=5)=\frac{6.4^{5} *e^{-6.4} }{5!} =\frac{17.84083537}{120} =0.1486736281\approx0.1487$
