The number of phone calls that Actuary Ben receives each day has a Poisson distribution with mean 0.1 during each weekday and me

Dovator [93]

Answer:

There is a 0.73% probability that Ben receives a total of 2 phone calls in a week.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

$e = 2.71828$ is the Euler number

$\mu$ is the mean in the given time interval.

The problem states that:

The number of phone calls that Actuary Ben receives each day has a Poisson distribution with mean 0.1 during each weekday and mean 0.2 each day during the weekend.

To find the mean during the time interval, we have to find the weighed mean of calls he receives per day.

There are 5 weekdays, with a mean of 0.1 calls per day.

The weekend is 2 days long, with a mean of 0.2 calls per day.

So:

$\mu = \frac{5(0.1) + 2(0.2)}{7} = 0.1286$

If today is Monday, what is the probability that Ben receives a total of 2 phone calls in a week?

This is $P(X = 2)$ . So:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 2) = \frac{e^{-0.1286}*0.1286^{2}}{(2)!} = 0.0073$

There is a 0.73% probability that Ben receives a total of 2 phone calls in a week.

A meteorologist forecasted that Monday's hight temperature would be 76F. On Monday, the temperature reached 80F. What is the per

mihalych1998 [28]

Answer: 5%

Step-by-step explanation:

A meteorologist predicted that Monday's hight temperature would be 76F and on Monday, the temperature reached 80F.

The percentage error will be

Percentage error=

(Exact value-Forecasted value)/exact value x 100

= 76-80/80 × 100

= -4/80 × 100

=4/80 × 100

= 400/80

= 5%

The percentage error is 5%.

Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2

vladimir2022 [97]

ANSWER

$x=-0.62$ or $x=1.62$

EXPLANATION

For $-x^2+y=1$

We make y the subject to obtain,

$y=x^2+1$

We can easily graph this function, because we just have to transform the graph of $y=x^2$ by shifting the intercept up to $1$ .

As for the straight line, $-x+y=2$ ,

We find the intercepts as follows,

When $y=0,x=-2$ .

When $x=0,y=2$ .

We plot the points $(-2,0)$ and

$(0,2)$ .

We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be

$x=-0.62$ or $x=1.62$

What is u = kx + ух, for x

Ivahew [28]

Answer:

<h2> $x= \frac{u}{k + y}$ </h2>

Step-by-step explanation:

u = kx + ух

First of all factorize x out at the right side of the equation

That's

u = x(k + y)

Divide both sides by ( k + y) to make x stand alone

That's

<h3> $\frac{x(k + y)}{k + y} = \frac{u}{k + y}$ </h3>

We have the final answer as

<h3> $x = \frac{u}{k + y}$ </h3>

Hope this helps you
