Answer:

The Poisson distribution uses the shape parameter denoted by  <em>λ</em>.

Step-by-step explanation:

A Poisson distribution is used to describe the distribution of the number of events that take place in a fixed interval of time.

For instance, number of customers arriving at a bank in an hour or the number of typos encountered in a book every 50 pages.

The Poisson distribution uses the shape parameter to compute the probabilities of different events.

The shape parameter is defined as the average number of occurrence in a given time interval. It is usually denoted by <em>λ</em>.

The probability mass function of a Poisson distribution is:

P(X=x)\frac{e^{-\lambda}\lambda^{x}}{x!};\ x=0,1,2,3...

How do you solve these problems?
Rzqust [24]
A)

\bf log_4(x)=3\\\\&#10;-----------------------------\\\\&#10;log_{{  a}}{{  a}}^x\implies x\qquad \qquad &#10;\boxed{{{  a}}^{log_{{  a}}x}=x}\impliedby &#10;\begin{array}{llll}&#10;\textit{we'll use this}\\&#10;\textit{cancellation rule}&#10;\end{array}\\\\&#10;-----------------------------\\\\&#10;4^{\cfrac{}{}log_4(x)}=4^3\implies x=4^3

b)

\bf 3^{2y}=81\qquad &#10;\begin{cases}&#10;81=3\cdot 3\cdot 3\cdot 3\\&#10;\qquad 3^4&#10;\end{cases}\implies 3^{2y}=3^4\impliedby &#10;\begin{array}{llll}&#10;\textit{same base}\\&#10;exponents\\&#10;must\ be\\&#10;the\ same&#10;\end{array}&#10;\\\\\\&#10;2y=4\implies y=\cfrac{4}{2}\implies y=2
