The number of errors in a textbook follow a poisson distribution with a mean of 0.01 errors per page. what is the probability th

neonofarm [45]

Mean number of errors in each page = 0.01
Mean number of errors in 100 pages = 0.01*100=1

It is possible to use the cumulative distribution function (CMF), but the math is a little more complex, involving the gamma-function. Tables and software are available for that purpose.

Thus it is easier to evaluate with a calculator for the individual cases of k=0,1,2 and 3.

The Poisson distribution has a PMF (probability mass function)

$P(k):=\frac{\lambda^ke^{-\lambda}}{k!}$
with λ = 1
=>
$P(0):=\frac{1^0e^{-1}}{0!}=0.3678794$
$P(1):=\frac{1^1e^{-1}}{1!}=0.3678794$
$P(2):=\frac{1^2e^{-1}}{2!}=0.1839397$
$P(3):=\frac{1^3e^{-1}}{3!}=0.0613132$
=>
$P(k$
or
P(k<=3)=0.9810 (to four decimal places)

How many solutions does 3(x-2)=22-x have

morpeh [17]

Answer:

x=7

Step-by-step explanation:

Start by distributing the 3:

(3)(x)+(3)(−2)=22-x

Now we have:

3x−6=−x+22

Add x to both sides:

3x−6+x=−x+22+x

Now we have:4x−6=22

Add 6 to both sides:

Add x to both sides.

3x−6+x=−x+22+x

4x−6+6=22+6

Now we have

4x=28

Divide both sides by 4

x=7
