If the points (4,2) (6,3) and (8,4) are on the graph of f, give three points on the graph of f^-1

Stels [109]

let's recall that an inverse function has the same pair of coordinates as the original function, but backwards, or namely the inverse's range is the original's domain.

$\bf \stackrel{f(x)}{\begin{array}{|cc|ll} \cline{1-2} 4&2\\ 6&3\\ 8&4\\ \cline{1-2} \end{array}}\qquad \qquad \stackrel{f^{-1}(x)}{\begin{array}{|cc|ll} \cline{1-2} 2&4\\ 3&6\\ 4&8\\ \cline{1-2} \end{array}}$

The average number of customers arriving at a gas station is 33 per hour during lunch hours. Use equation to denote the number o

Paha777 [63]

Answer:

The equation denoting the number of arrivals in 5 minutes is, $\frac{33}{60}\times5$ .

The number of arrivals in 5 minutes is 2.75.

Step-by-step explanation:

Let <em>X</em> = number of customers arriving at a gas station in an hour.

The average customers arriving at a gas station in an hour is, <em>λ</em> = 33.

The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em>.

The probability mass function of a Poisson distribution is:

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

In 60 minutes the number of arrivals is, 33.

In 1 minute the number of arrival will be, $\frac{33}{60}$ .

Then in 5 minutes the number of arrivals will be, $\frac{33}{60}\times5$ .

The equation denoting the number of arrivals in 5 minutes is, $\frac{33}{60}\times5$ .

The number of arrivals in 5 minutes is

$\frac{33}{60}\times5=2.75$

Thus, the number of arrivals in 5 minutes is 2.75.
