The caller times at a customer service center has an exponential distribution with an average of 22 seconds. Find the probabilit

jenyasd209 [6]

Answer:

The probability that a randomly selected call time will be less than 30 seconds is 0.7443.

Step-by-step explanation:

We are given that the caller times at a customer service center has an exponential distribution with an average of 22 seconds.

Let X = caller times at a customer service center

The probability distribution (pdf) of the exponential distribution is given by;

$f(x) = \lambda e^{-\lambda x} ; x > 0$

Here, $\lambda$ = exponential parameter

Now, the mean of the exponential distribution is given by;

Mean = $\frac{1}{\lambda}$

So, $22=\frac{1}{\lambda}$ ⇒ $\lambda=\frac{1}{22}$

SO, X ~ Exp( $\lambda=\frac{1}{22}$ )

To find the given probability we will use cumulative distribution function (cdf) of the exponential distribution, i.e;

$P(X\leq x) = 1 - e^{-\lambda x}$ ; x > 0

Now, the probability that a randomly selected call time will be less than 30 seconds is given by = P(X < 30 seconds)

P(X < 30) = $1 - e^{-\frac{1}{22} \times 30}$

= 1 - 0.2557

= 0.7443

Given the function below, find x so that,<br> f(x)=10

ch4aika [34]

To find the slope and the -intercept of the line, first write the function as an equation, by substituting for

y=10
y=0x+10
y=0x+10 , m=0
y=0x+10 , m=0 , b=10

m=0 , b=10

The slope of the line is m=0 and the y-intercept is b=10

Which of the following fractions can be represented by a terminating decimal? OA 8/9 OB)13/8 OC) 4/3 OD) 6/11

velikii [3]

Answer:

$\frac{13}{8}$

Step-by-step explanation:

$\frac{13}{8} \: \: cuz \: when \: u \: simplify \: into \: a \: decimal \: would \: be \: 1.625 \\ and \: if \: u \: round \: would \: be \: 2 \: so \: u \: take \: out \: the \: decimal \:$
